'Related To' Clause
The statutory language in the FAAAA (and the Airline Deregulation Act) that preempts state laws having a connection or reference to carrier or broker prices, routes, or services. Courts have interpreted this phrase broadly, but there is debate over just how broad its reach is.
18 U.S.C. § 922(g)(3)
A federal statute that makes it unlawful for any person who is 'an unlawful user of or addicted to any controlled substance' to ship, transport, possess, or receive firearms or ammunition. This is the specific law at issue in this case.
Abrogation of sovereign immunity
The act of Congress stripping away a sovereign's legal protection from being sued. Courts require a clear statement from Congress before finding abrogation, though no specific 'magic words' are required.
Abscondment
The act of fleeing or hiding from supervision, typically by failing to report to a probation officer and making oneself unavailable. There is no statutory definition, and courts disagree on exactly what conduct qualifies — some require only a failure to appear, while others require a deliberate pattern of conduct that makes supervision impossible.
Absentee Ballot
A ballot cast by a voter who is unable to appear in person at a polling place on Election Day, typically submitted by mail before the election. Absentee voting is particularly important for military personnel, overseas citizens, and voters with disabilities.
Abuse of discretion
The standard by which appellate courts review a district court's decision on compassionate release. A court abuses its discretion when it makes a decision that is clearly unreasonable, arbitrary, or not supported by the facts and law. This deferential standard gives trial judges significant latitude but allows reversal in extreme cases.
Acting under a federal officer
A requirement of the Federal Officer Removal Act meaning the defendant must have been working under the direction or authority of a federal officer or agency—more than merely being regulated by the federal government. It typically applies to government contractors or those carrying out delegated federal duties.
Actual innocence
A claim that a convicted person did not actually commit the crime for which they were convicted. The Supreme Court has never definitively ruled whether a freestanding claim of actual innocence—unaccompanied by a separate constitutional violation—can provide a basis for federal habeas relief.
Actuarial Assumptions
Professional predictions about future uncertain events that affect pension costs, such as how long retirees will live, what investment returns the plan will earn, and how many employees will retire early. These are not simple facts but professional judgments that can vary among actuaries, and under the statute they must be 'reasonable' and represent the actuary's 'best estimate' of the plan's anticipated experience.
Adaptive Functioning
A person's practical ability to perform everyday tasks and navigate daily life independently, such as managing money, communicating effectively, maintaining employment, and caring for oneself. It is one of the three diagnostic criteria for intellectual disability alongside IQ and age of onset.
Administrative Procedure Act (APA)
A federal statute that establishes procedural requirements for agency action, including notice-and-comment rulemaking, and provides standards for judicial review of agency decisions. Agencies must follow APA procedures and their actions must not be arbitrary and capricious.
AEDPA (Antiterrorism and Effective Death Penalty Act)
A 1996 federal law passed in the wake of the Oklahoma City bombing that significantly restricted habeas corpus relief for both state and federal prisoners. It imposed time limits, heightened standards of review, and gatekeeping requirements for successive petitions, all in the name of promoting finality of criminal convictions.
AEDPA (Antiterrorism Effective Death Penalty Act)
A 1996 federal statute that severely restricted the availability of federal habeas corpus relief for state prisoners by limiting federal review to cases where state courts have decided questions contrary to or unreasonably applied clearly established federal law. It represents one of the most significant limitations on federal review of state convictions.
Affidavit of Merit (AOM)
A sworn statement by a qualified expert — here, a medical professional — filed at or near the beginning of a lawsuit, asserting that there are reasonable grounds for the claim. Many states require AOMs in medical malpractice cases to filter out frivolous lawsuits before they proceed.
Age verification
A mechanism requiring users to confirm they are adults before accessing age-restricted content or services. Methods range from showing a government-issued ID to biometric scanning (such as a face scan) or using transactional data such as credit or mortgage records to infer age.
Agency Authority
The scope of powers delegated to a federal agency by Congress through statute. An agency may only exercise powers explicitly or implicitly granted by law; regulatory actions beyond this scope are considered ultra vires and subject to judicial invalidation.
Agency Principles (Principal-Agent Law)
Legal rules governing the relationship between a principal (the party giving directions) and an agent (the party carrying them out). Under these principles, when an agent acts within authority validly delegated by the principal, the principal — not the agent — bears responsibility. The government argues Yearsley is simply an application of these ordinary principles.
Amicus Curiae
Latin for 'friend of the court.' An amicus curiae is a person or organization that is not a party to the lawsuit but files a brief to give the court additional information or arguments that might be helpful. Courts are not required to follow or even consider amicus briefs.
Ancien régime
A French term literally meaning 'old regime,' used in Supreme Court jurisprudence to describe the earlier era when courts freely implied private rights of action from federal statutes without requiring clear textual support. The Court moved away from this approach beginning with Cort v. Ash in 1975.
ANDA (Abbreviated New Drug Application)
A streamlined application process under FDA regulations that allows generic drug manufacturers to obtain approval without repeating all safety and efficacy testing already done for branded drugs. Filing an ANDA can trigger patent disputes under the Hatch-Waxman Act.
Anti-Circularity Principle
A constitutional rule preventing the government from using its own laws to redefine or eliminate property rights in a way that avoids paying just compensation. Without this principle, governments could simply write statutes declaring that certain property interests don't exist, and then take them without compensation.
Apprendi rule
A constitutional principle from Apprendi v. New Jersey holding that any fact (other than a prior conviction) that increases the maximum punishment a defendant can receive must be found by a jury beyond a reasonable doubt. This rule has been extended to monetary penalties.
Appropriate relief
The statutory term used in both RFRA and RLUIPA to describe the remedies available to a person whose religious exercise has been violated. The central dispute in this case is whether 'appropriate relief' clearly includes money damages when the defendant is an individual state official rather than the state itself.
Arbitrary and Capricious
A standard of review under the Administrative Procedure Act meaning that agency action must have a rational basis and cannot be taken without consideration of relevant factors. Actions that are unexplained, inconsistent, or based on irrational reasoning can be set aside as arbitrary and capricious.
Arm of the State
A legal classification for entities that are so closely tied to a state government that they are treated as the state itself for purposes of sovereign immunity. Courts examine factors like state control, financial relationship, and the entity's function to determine whether an entity qualifies.
Article III standing
The constitutional requirement that a plaintiff must show three things to bring a case in federal court: (1) an actual or imminent injury, (2) caused by the defendant's conduct, and (3) that can be fixed by a court ruling. Without standing, federal courts lack power to hear the case.
Artifact Noun
A linguistic concept holding that nouns referring to man-made objects are defined by their intended design and function rather than their current physical state of completion. Under this theory, an incomplete version of an object can still be called by that object's name if it is clearly designed to serve that function.
As-Applied Challenge
A lawsuit arguing that a law or regulation is unlawful only as applied to a specific person, product, or situation — not that the rule is generally invalid. These challenges are resolved on concrete facts and can leave the rule intact for other applications.
Asylum
A form of legal protection that allows people who have fled their home country due to persecution based on race, religion, nationality, political opinion, or membership in a particular social group to remain legally in the United States.
Attorney-client privilege
A legal protection that keeps communications between a lawyer and client confidential. Several justices raised concerns about whether cross-examination about overnight conversations would violate this privilege, potentially undermining one proposed safeguard against improper coaching.
Auxiliary legal principles
Sub-rules or guidelines that courts develop over time to help apply a broad legal standard to specific situations. They sit between the general statutory term and the specific facts of individual cases, providing guidance for recurring factual patterns.
Ballot access
The legal right and procedural requirements for candidates to appear on election ballots. States administer ballot access rules, including verification of candidate eligibility to hold office. This case involves whether states may enforce Section 3 disqualifications by denying ballot access to ineligible candidates.
Bankruptcy Estate
When a person files for bankruptcy, all of their property and legal interests at that moment are gathered into a legal 'estate' controlled by a trustee on behalf of creditors. The key question in this case is whether that estate also captures property and lawsuits that arise after the bankruptcy filing but while the case is still open.
Bankruptcy Trustee
A court-appointed person who manages the bankruptcy estate on behalf of creditors. The trustee collects and sells non-exempt property, distributes the proceeds to creditors, and has the authority to pursue legal claims that belong to the estate.
Base contribution limits
The maximum amount an individual may donate directly to a single candidate, party committee, or PAC per election cycle. Currently set at approximately $3,300 per election for candidates and about $44,000 per year for national party committees. These limits are the foundational mechanism for preventing corruption in campaign finance law.
Batson challenge
A formal objection raised during jury selection to question whether an opposing party has used peremptory strikes to remove jurors based on race or other protected characteristics. The challenging party must show a pattern suggesting race-based motivation, and the striking party must provide race-neutral reasons.
Belt-and-Suspenders Drafting
A legislative drafting approach where Congress uses overlapping or redundant terms to ensure complete coverage of a subject, preferring to have some redundancy rather than risk leaving gaps. It reflects a 'better safe than sorry' approach to lawmaking.
Best Estimate Requirement
A statutory standard under Section 1393 requiring that the actuarial assumptions used for withdrawal liability represent the actuary's own best estimate of the plan's anticipated future experience. This is a subjective test designed to ensure the actuary exercises independent professional judgment rather than bowing to pressure from plan trustees or others.
Black codes
Laws passed primarily in Southern states immediately after the Civil War that restricted the rights of newly freed Black Americans, including their right to bear arms. These laws were designed to maintain white supremacy and keep formerly enslaved people in a condition of near-servitude.
Blockburger test
A legal test used to determine whether two criminal charges constitute the 'same offense' for double jeopardy purposes. Two offenses are different only if each requires proof of an element that the other does not. If one offense is entirely contained within the other (a lesser-included offense), they are the same offense under Blockburger.
Board of Immigration Appeals (BIA)
The highest administrative tribunal for interpreting and applying immigration law within the Department of Justice. It reviews decisions made by immigration judges and its decisions can be appealed to federal circuit courts.
Boyle defense (government contractor defense)
A judicially created immunity for government contractors who build products to reasonably precise government specifications. It requires that the government approved the specifications, the product conformed to them, and the contractor warned the government about known dangers.
Bruen two-step framework
The test established in NYSRPA v. Bruen for evaluating gun regulations. Step one asks whether the law regulates conduct covered by the Second Amendment's text (arms-bearing conduct). Step two requires the government to show the regulation is consistent with the nation's historical tradition of firearms regulation.
But-for causation
A test asking whether a particular outcome would have been different 'but for' (without) a certain factor. In discrimination law, it asks whether the person would have been treated differently but for their sex, race, or other protected characteristic.
Carceral tolling
A statutory provision (Section 3624(e)) that pauses the running of a supervised release term when the supervisee is imprisoned for another offense. Unlike fugitive tolling, this type of tolling is explicitly written into federal law.
Causation
The legal and factual connection between a defendant's wrongful conduct and the plaintiff's injury. Causation requires both actual cause (but-for the defendant's conduct, the harm would not have occurred) and proximate cause (the harm was a foreseeable result of the defendant's conduct). In medical malpractice, establishing causation often requires expert testimony.
Cause of Action
A legal right to sue someone based on specific facts — for example, the right to sue for damages after being injured due to another's negligence. A cause of action does not exist until the underlying event (like an injury) actually happens.
Certification / Authorization
Under AEDPA, before a prisoner can file a second or successive habeas petition, a three-judge panel of the court of appeals must certify (authorize) that the petition meets certain statutory requirements. This is a gatekeeping mechanism designed to screen out meritless filings.
Certified claim
A claim officially validated by the Foreign Claims Settlement Commission (FCSC), establishing that a U.S. national had property confiscated by the Cuban government and assigning a dollar value to the loss. Under the Helms-Burton Act, the FCSC's determinations of fact and law are conclusive and not subject to judicial review.
Certiorari
A formal order from the Supreme Court agreeing to review a lower court's decision. Because the Supreme Court chooses which cases it hears, granting certiorari (often called 'cert') means the Court has decided the legal question is important enough to address.
Certiorari (Cert)
The formal process by which the Supreme Court agrees to review a lower court's decision. Because the Supreme Court has nearly complete control over its docket, it grants certiorari only in cases it considers important, usually where lower courts are divided or a significant legal question needs resolution.
Certiorari before judgment
A rare Supreme Court procedure in which the Court accepts a case directly from a lower court (bypassing normal appellate process) before the lower court has completed its review. The petition must concern a question of exceptional importance. The Court granted Trump's certiorari petition before judgment in December 2025.
Chain of privity
A legal concept from contract law referring to the connected relationships between parties to related agreements. In this case, it describes the argument that obligations flow from the federal government to the state (via the funding agreement) and then from the state to its employees (via employment), binding each link in the chain.
Chapter 7 Bankruptcy
A type of personal bankruptcy that allows individuals to have most of their debts wiped out (discharged) in exchange for giving up non-exempt property to a trustee who sells it to pay creditors. It is often called 'liquidation' bankruptcy and is intended to give debtors a fresh financial start.
Charming Betsy canon
A longstanding rule of statutory interpretation holding that courts should construe federal laws to avoid conflicts with international law whenever a reasonable interpretation allows it.
Chevron Deference
A two-step judicial review framework for evaluating agency interpretations of statutes they administer. First, the court examines whether Congress directly addressed the precise question; if not, the court asks whether the agency's interpretation is reasonable. Agencies receive significant deference at the second step, even if courts might prefer a different reading.
Chilling effect
The discouraging or deterring impact on the exercise of constitutional rights, particularly First Amendment freedoms, caused by government action or the threat of government action. A person refrains from lawful activity out of fear of consequences.
Circuit Split
When different federal appeals courts (circuits) reach conflicting conclusions on the same legal question, creating inconsistent law across the country. The Supreme Court often grants certiorari to resolve such splits and establish a uniform national rule.
Claim Interpretation
The process by which courts determine the meaning and scope of patent claim language. Proper interpretation determines what products or processes fall within the patent's protection and is critical to infringement analysis.
Class Action
A type of lawsuit where one or a few people sue on behalf of a much larger group of people who have similar legal claims. It allows many individuals with smaller or harder-to-litigate claims to join together in a single case.
Class Certification
The formal court ruling that allows a lawsuit to proceed as a class action. A judge must find that the group of people is large enough, that they share common legal questions, and that the named plaintiffs can adequately represent the whole group.
Clear indication (or clear congressional intent)
The standard the Supreme Court has used in double jeopardy cases requiring that Congress must clearly signal its intent to authorize multiple punishments for the same offense before courts will impose them. This is sometimes described as a presumption that Congress does not intend cumulative punishments unless it says so.
Clear notice requirement
A rule from Spending Clause jurisprudence requiring that conditions attached to federal funding be stated clearly and unambiguously so that states know what they are agreeing to when they accept the money. This is sometimes described as analogous to a contract — both parties must understand the terms.
Clear statement rule
A principle of statutory interpretation requiring that Congress speak clearly and unambiguously when it intends to take certain significant actions, such as creating a new private right of action. The rule places the burden on those claiming Congress acted to show unmistakable statutory language.
Clearly established law
Under AEDPA, a legal principle that has been repeatedly recognized by the Supreme Court as settled constitutional doctrine. A state court decision violates clearly established law if it applies the law in a manner contrary to Supreme Court precedent, but disagreement with that precedent is not enough to grant habeas relief.
Closed-end fund
A type of investment fund that raises a fixed amount of capital through an initial offering and then trades on stock exchanges. Unlike open-end mutual funds, shareholders cannot redeem shares at net asset value, which can lead to shares trading at a discount.
Closely drawn scrutiny
The level of judicial review applied to contribution limits under campaign finance law. It is less demanding than strict scrutiny but still requires the government to show the restriction is closely connected to a sufficiently important interest. The restriction must be narrowly tailored but need not be the least restrictive means available.
Code Pleading
An older and more demanding pleading system that requires parties to state specific facts supporting each element of their claim, as opposed to notice pleading. The Federal Rules of Civil Procedure were designed to replace code pleading with the simpler notice-pleading standard.
Collateral attack
A challenge to the validity of a court judgment made in a separate proceeding rather than through a direct appeal. A party may collaterally attack a judgment by arguing it is void, for example, when the judgment creditor tries to enforce it in a different court.
Collateral estoppel
A legal doctrine that prevents a party from relitigating an issue that has already been decided in a prior proceeding. In this context, a criminal conviction can establish facts that a victim can then rely on in a separate civil suit without re-proving them.
Collateral Order Doctrine
A judge-made exception to the final judgment rule that allows immediate appeal of certain pretrial court orders that are conclusive, resolve an important question completely separate from the merits, and would be effectively unreviewable if the party had to wait until after trial. It is meant to be narrow and sparingly applied.
Colorable federal defense
A requirement for federal officer removal meaning the defendant must be able to raise at least a plausible (non-frivolous) defense based on federal law. It does not require proving the defense will succeed, only that it is not clearly meritless. This is considered a low bar.
Combatant activities exception
A provision in the Federal Tort Claims Act that bars lawsuits against the United States for injuries arising out of combatant activities during time of war. It covers not only direct combat but also actions necessary to and taken in connection with military operations.
Comity
A principle of international law and civil procedure requiring that courts in one country respect the sovereignty and legal processes of other countries. Comity may limit the extraterritorial reach of U.S. court orders and discovery demands, particularly when such orders would burden foreign nationals or interfere with foreign legal processes.
Commercial activity exception
An exception under FSIA Section 1605 that strips a foreign sovereign's immunity when the lawsuit is based on the sovereign's commercial activity in the United States or having a direct effect in the United States.
Community Caretaking
A concept describing police activity aimed at helping community members rather than investigating crime, such as welfare checks. The Supreme Court in Caniglia rejected this as a standalone exception to the warrant requirement for homes, though Montana's courts continued to use the terminology.
Compassionate release
A legal mechanism allowing the reduction of a federal prisoner's sentence based on extraordinary and compelling reasons. Originally, only the Bureau of Prisons could file these motions, but the First Step Act of 2018 allowed prisoners to file directly with courts after exhausting BOP remedies.
Compelling Interest
Under strict scrutiny, the government must show that its use of a racial classification serves a goal of the highest order. In redistricting, the Court has assumed without deciding that compliance with Section 2 of the Voting Rights Act is such an interest, but this case asks the Court to finally resolve that question.
Competitive injury (electoral context)
Harm to a candidate's or party's competitive position in an election. This includes being placed at a disadvantage relative to opponents due to a change in election rules. Courts have recognized this as a basis for standing in some election cases.
Complete Diversity
A requirement for federal diversity jurisdiction meaning that every plaintiff must be a citizen of a different state from every defendant. If even one plaintiff shares state citizenship with one defendant, diversity jurisdiction does not exist.
Composite Score
A statistically derived overall IQ score calculated by combining results from multiple test subtests or multiple test administrations using a standardized formula, considered more accurate than a single test score or a simple average.
Concession
A grant by a government or property owner allowing another party to use property or exercise certain rights for a specified period and purpose. It is typically more limited than full ownership and reverts to the grantor when the term expires.
Conclusive and preclusive power
Constitutional authority that belongs exclusively to the President and cannot be shared with or limited by Congress. Used in Trump v. United States to describe core presidential functions like directing criminal prosecutions.
Conduit bribery
A scheme in which a donor attempts to bribe a candidate indirectly by routing money through an intermediary (like a political party) rather than giving directly to the candidate. Petitioners argue this is an implausible theory because the intermediary has its own interests and is unlikely to cooperate.
Confiscated property
Under the Helms-Burton Act, property that the Cuban government seized ownership or control of without providing adequate compensation. Property remains 'confiscated' until the claim is resolved through compensation, the property is returned, or Cuba transitions to democracy.
Conflict preemption
A form of preemption where a specific state law is displaced because it directly conflicts with federal law or policy — either making it impossible to comply with both, or because state law stands as an obstacle to achieving federal objectives.
Conforming amendment
A legislative change made to harmonize different parts of a statute after a substantive amendment is enacted. Conforming amendments are typically considered technical adjustments, though the Court has held that even conforming amendments must be given their full textual effect.
Congressional Intent
The purpose and meaning that Congress intended when enacting a statute, as discerned from the statute's language, structure, legislative history, and context. Courts look to congressional intent to determine how broadly a statute applies.
Congruence and Proportionality
The test from City of Boerne v. Flores for evaluating whether Congress has exceeded its enforcement power under the Reconstruction Amendments. Legislation must be congruent to the constitutional violation it targets and proportional in scope — not going too far beyond what the amendment itself requires.
Consecutive sentences
Prison terms that must be served one after the other rather than at the same time (concurrently). Section 924(c)(1)(D)(ii) mandates that any sentence imposed under § 924(c) must run consecutively to any other sentence, which the amicus argues shows Congress intended cumulative punishment.
Constitutional avoidance
An interpretive principle where courts prefer a construction of a statute that avoids raising serious constitutional problems over one that would create such problems. It applies only when there are genuinely competing plausible interpretations of the statute.
Constitutional Challenge
A legal argument that a government action violates the U.S. Constitution or constitutional principles. Such challenges invoke fundamental rights or structural constitutional provisions as limits on government authority.
Constitutional liquidation
The idea that the meaning of ambiguous constitutional provisions can be settled over time through consistent practice by the political branches. Respondents argued that over a century of Congress creating independent agencies, Presidents signing those laws, and the Court upholding them has liquidated the constitutional question in their favor.
Constructive denial
A situation where, although there is no explicit refusal to provide something, the conditions or circumstances effectively deny access. In Title IX, a constructive denial of educational opportunity can constitute discrimination even without a formal exclusion.
Content-based restriction
A law that regulates speech based on its subject matter, topic, or viewpoint. Content-based restrictions are presumptively unconstitutional and must survive strict scrutiny to be upheld.
Contributory copyright infringement
A form of secondary liability where someone who doesn't directly copy or distribute copyrighted material can still be held liable if they knowingly contribute to another person's infringement. Courts have recognized this through common law principles even though the Copyright Act doesn't explicitly mention it.
Controlled Substance
A drug or chemical regulated under federal law, categorized into schedules based on their potential for abuse and accepted medical use. Marijuana is classified as a Schedule I controlled substance under federal law, meaning it is treated as having a high potential for abuse and no accepted medical use, even though many states have legalized it.
Convention Against Torture (CAT)
An international treaty that prohibits returning individuals to countries where they would face torture. Under U.S. law, courts generally review de novo whether undisputed facts demonstrate torture under CAT, which petitioner argues supports de novo review for the analogous persecution question.
Conversion
A tort that occurs when someone intentionally exercises unauthorized control over another person's property, depriving the owner of its use. It is essentially the civil equivalent of theft. Notably, Congress did not include conversion in the FTCA's intentional tort exception.
Coordinated expenditures
Money spent by a political party in coordination with a candidate's campaign. Federal law treats these as functionally equivalent to direct contributions to the candidate because the candidate effectively controls how the money is spent. They are subject to limits under federal campaign finance law.
Covert content manipulation
The government's central concern that China could secretly direct TikTok's recommendation algorithm — without users' knowledge — to suppress certain viewpoints, amplify others, or sow social discord to serve Chinese geopolitical goals.
Cracking and Packing
Two forms of gerrymandering. Cracking splits a cohesive group across multiple districts so they cannot form a majority in any. Packing concentrates a group into as few districts as possible, wasting their votes and limiting their overall influence. Both can constitute vote dilution under Section 2.
Critical Machining Operations Test
The standard ATF applied before 2022, examining whether the key manufacturing steps needed to create a frame or receiver's functional areas — specifically the holes and material removals that allow firing components to be installed — had already been performed. If those critical operations were done, the item was regulated; if they remained undone, it was not.
Cross-reference (statutory)
A provision in one section of a statute that directs the reader to another section, incorporating some or all of that other section's requirements. Disputes often arise about exactly how much of the referenced section is incorporated — particularly when the referenced section was written with different parties in mind.
Cumulative punishment
Imposing separate penalties for two or more offenses arising from the same conduct, typically resulting in stacked or consecutive sentences. The key legal question in double jeopardy cases is whether Congress clearly authorized cumulative punishment when two charges constitute the same offense.
Damages
Monetary compensation awarded by a court to an injured party to make them whole for losses caused by another's wrongful conduct. In medical malpractice cases, damages may include economic losses (medical expenses, lost wages), non-economic losses (pain and suffering), and in some jurisdictions, punitive damages (to punish egregious conduct).
De facto officer
A person who occupies a government position and exercises its powers under color of authority, even though there may be a legal defect in their appointment or right to hold the office. Their official acts are generally treated as valid.
De novo review
A standard of review where the court decides the question fresh, exercising its own independent judgment without giving any deference to the lower tribunal's conclusion. The court effectively starts from scratch.
Debt Limitation Clause
A provision in a state constitution that limits the amount of debt the state government can incur, often requiring public approval through a vote before new debt is issued. Creating a separate public corporation allows the state to borrow money through that entity without triggering these constitutional limits.
Decision of 1789
A debate in the First Congress over whether the President had implicit constitutional authority to remove executive officers without Senate approval. The majority sided with James Madison's view that removal power is inherent in executive power, and this is often cited as historical evidence for presidential removal authority.
Default judgment
A judgment entered against a party who fails to appear in court or respond to legal proceedings. If a defendant does not answer a complaint or show up, the court may enter judgment in favor of the plaintiff without a trial.
Defense Base Act
A 1941 federal law that provides workers' compensation coverage for civilian employees of government contractors working on U.S. military bases overseas. In exchange for guaranteed compensation, employees give up their common law tort claims against the contractor.
Deference
The degree to which courts defer to or respect an agency's interpretation of law or its factual findings. Under the overruled Chevron standard, courts deferred to reasonable agency interpretations; under current law, courts exercise independent judgment.
Delegation
The transfer of authority from Congress to an administrative agency, allowing the agency to make rules and decisions within a defined scope. Delegation questions ask whether Congress properly granted power to the agency and whether the agency stayed within those bounds.
Departure
A sentencing decision that falls outside the recommended guidelines range. A judge may 'depart' upward or downward from the guidelines based on factors not adequately considered by the guidelines themselves. In this case, the practical question is whether post-term conduct changes the guidelines range itself or merely serves as a basis for departure.
Derivative Sovereign Immunity
The theory that a private contractor can 'derive' or inherit the government's own immunity from suit by virtue of performing the government's work. The Supreme Court put this concept in scare quotes in Campbell-Ewald and rejected it as applied to a contractor that had not followed government directions.
DIG (Dismiss as Improvidently Granted)
When the Supreme Court dismisses a case after granting certiorari upon realizing the case does not properly present the legal question it intended to decide, often because of factual complications or because the question presented doesn't match the actual dispute.
Digital communications
Electronic messages and information transmitted over networks, including email, text messages, instant messages, and other electronically stored communications. Courts have increasingly recognized that digital communications deserve Fourth Amendment protection because they often contain highly sensitive personal information.
Discharge
The legal elimination of a debtor's personal liability for certain debts as a result of bankruptcy. Once a discharge is granted, creditors can no longer legally pursue the debtor for those debts. In Chapter 7, a discharge typically occurs relatively quickly, but the estate may remain open longer.
Disclosure (or Discovery)
The process in civil litigation by which parties obtain information and documents from one another and from non-parties relevant to the claims in dispute. Disclosure is governed by the Federal Rules of Civil Procedure and requires that parties produce responsive documents and information that is not protected by privilege. Disclosure can include compelling parties to identify themselves and provide information about their identities, assets, and conduct.
Discount Rate
An interest rate used to calculate the present value of future payments. In pension contexts, it represents the expected rate of return on the plan's investments. A lower discount rate increases the calculated present value of future pension obligations (and thus withdrawal liability), because it assumes the plan's investments will earn less, requiring more money today to fund the same future payments.
Discrete and Insular Minority
A concept from Footnote 4 of Carolene Products describing groups that are identifiable, politically powerless, and historically subjected to discrimination. Laws targeting such groups may warrant heightened judicial scrutiny because the democratic process may not protect them.
Discretionary Enforcement
The legal principle that government officials — especially in law enforcement and immigration — often have broad authority to decide how, when, and against whom to apply the law, and courts generally cannot second-guess those judgment calls.
Discrimination
In legal contexts, unlawful differential treatment of individuals based on protected characteristics such as race, color, religion, sex, national origin, age, or disability. Discrimination may be intentional (disparate treatment) or the result of a facially neutral policy with a discriminatory effect (disparate impact).
Disparate Impact
A theory of discrimination based on a facially neutral policy or practice that has a disproportionately adverse effect on members of a protected class, regardless of the defendant's discriminatory intent. The plaintiff must show that a specific employment practice causes a significant statistical disparity, and the defendant must justify the practice as job-related and necessary.
Disparate Treatment
A form of discrimination in which an employer, business, or institution intentionally treats individuals differently based on a protected characteristic. It requires proof that the defendant knew of and acted because of the plaintiff's membership in a protected class.
Disqualification clause
A constitutional provision that makes a person ineligible to hold public office based on past conduct or characteristics. The Fourteenth Amendment's Section 3 is a disqualification clause that bars persons who engaged in insurrection from holding office.
Do-over bar (relitigation bar)
Section 2244(b)(1)'s prohibition on raising a claim in a successive habeas petition that was already presented in a prior petition. It is an absolute bar — unlike (b)(2), which allows new claims meeting certain criteria — and prevents prisoners from relitigating claims that have already been decided.
Double Jeopardy
A constitutional protection found in the Fifth Amendment that prohibits the government from prosecuting or punishing a person more than once for the same criminal offense. Once 'jeopardy attaches,' the government generally cannot retry a defendant for the same crime.
Double Jeopardy Clause
The Fifth Amendment provision that protects individuals from being tried or punished twice for the same offense. In this case, it is invoked to challenge whether a defendant can receive two separate convictions and punishments under overlapping federal gun statutes for a single fatal shooting.
Due Process
A constitutional guarantee (in the Fifth and Fourteenth Amendments) that the government must follow fair procedures before depriving a person of life, liberty, or property. Due process requires adequate notice and an opportunity to be heard. In the jurisdictional context, due process limits when courts can exercise authority over defendants.
Duty of Care
A legal obligation to act reasonably and prudently to avoid causing harm to another person. In medical contexts, healthcare providers and institutions owe patients a duty to exercise reasonable care in diagnosis, treatment, and monitoring. A breach of this duty can form the basis for a negligence claim.
Earmarking rules
Federal regulations that treat contributions designated or directed to a specific candidate through an intermediary as contributions directly to that candidate, subject to individual contribution limits. Violating these rules is a federal crime. They are intended to prevent donors from circumventing contribution limits by funneling money through third parties.
Editorial discretion
A publisher's or platform's constitutionally protected right to decide what content to include, promote, or exclude — the functional equivalent of a newspaper editor's choices about which stories to run.
Effective Unreviewability
One of the three requirements for the collateral order doctrine: the right at issue must be one that would be effectively lost forever if the party is forced to wait until after trial to appeal. For true immunities from suit, the right not to be tried at all is destroyed the moment trial begins.
Effects Doctrine
A principle of jurisdiction holding that a nation may prosecute foreign conduct that produces effects within its territory or harms its citizens or interests, even if the conduct itself occurred abroad. The effects doctrine is sometimes invoked to justify extraterritorial jurisdiction.
Eighth Amendment
The provision of the U.S. Constitution prohibiting 'cruel and unusual punishments.' The Supreme Court has interpreted this to forbid executing certain categories of people, including those who are intellectually disabled, based on the 'evolving standards of decency' of American society.
Ejusdem Generis
A legal interpretation rule meaning 'of the same kind.' When a statute lists specific items followed by a general catch-all term like 'or otherwise,' the general term is interpreted to include only things similar in nature to the specific items listed.
Election Finality
The principle that election results should be certified and become official within a reasonable and predictable timeframe after Election Day, avoiding prolonged uncertainty about who won. States often cite this interest when defending strict ballot-receipt deadlines.
Elections Clause
A provision in Article I of the U.S. Constitution that gives states the authority to regulate the time, place, and manner of congressional elections, but allows Congress to override those state rules by passing federal legislation.
Eleventh Amendment
A constitutional amendment that prohibits federal courts from hearing lawsuits brought against a state by citizens of another state or foreign country. It has been interpreted broadly to reflect a deeper constitutional principle of state sovereign immunity that extends beyond its literal text.
Emergency Aid Exception
A recognized exception to the Fourth Amendment's warrant requirement that permits police to enter a home without a warrant when they have reason to believe someone inside is seriously injured or faces imminent serious injury. It is justified by the urgent need to save lives rather than to investigate crimes.
Endogenous vs. Circulating Testosterone
Endogenous testosterone is what the body naturally produces; circulating testosterone is the total amount in the bloodstream at a given time, including from external sources like hormone therapy. The distinction matters because transgender women on hormone therapy suppress endogenous testosterone but may have circulating testosterone from medication.
Enforcement Power
The authority granted to Congress under Section 2 of the Fifteenth Amendment and Section 5 of the Fourteenth Amendment to pass legislation enforcing those amendments' guarantees. This power allows Congress to go beyond what the amendments prohibit by their own force, such as enacting effects-based tests rather than requiring proof of intentional discrimination.
Equal Protection Clause
Part of the Fourteenth Amendment to the U.S. Constitution, which provides that no state shall 'deny to any person within its jurisdiction the equal protection of the laws.' It is the primary constitutional provision used to challenge laws that treat people differently based on characteristics like race, sex, or national origin.
Equitable tolling
A legal doctrine that allows a court to extend a filing deadline when a party was prevented from meeting it through no fault of their own, such as being in a coma or being misled about their rights. In the habeas context, it can excuse missing the one-year Section 2255 filing deadline.
Erie Doctrine
The principle from Erie Railroad v. Tompkins that federal courts hearing state-law claims must apply state substantive law but use federal procedural law. When no federal rule directly applies, courts use a balancing test considering whether failing to apply state law would lead to forum shopping or inequitable outcomes.
Erie Guess
When a federal court sitting in diversity must predict how a state's highest court would rule on an unsettled question of state law, since federal courts in diversity cases must apply state substantive law. Named after Erie Railroad Co. v. Tompkins.
ERISA (Employee Retirement Income Security Act)
A comprehensive 1974 federal law that sets minimum standards for most private pension and health plans to protect participants. ERISA establishes rules for plan funding, reporting, fiduciary duties, and participants' rights. The MPPAA's withdrawal liability provisions are part of ERISA.
Evolving Standards of Decency
The constitutional framework used by the Supreme Court to define the scope of Eighth Amendment protections. The Court looks to objective evidence—especially state legislative enactments—of society's contemporary moral views to determine whether a punishment is cruel and unusual.
Ex Parte Young Doctrine
A legal doctrine allowing lawsuits against state officials in their official capacity seeking prospective injunctive relief (a court order to stop ongoing violations of law), even when the state itself would be immune from suit. It does not allow suits for monetary damages from the state treasury.
Ex Post Facto Clause
A constitutional provision (Article I, Sections 9 and 10) that prohibits the government from passing laws that retroactively criminalize conduct, increase punishment, or change the rules of evidence to the disadvantage of the defendant after the crime was committed. It only applies to criminal punishments, not civil measures.
Exceptions Clause
Article III, Section 2 of the Constitution grants the Supreme Court appellate jurisdiction 'with such Exceptions, and under such Regulations as the Congress shall make.' This clause gives Congress power to limit the Court's appellate jurisdiction, but its outer boundaries remain unresolved after over 200 years.
Execution immunity
A legal protection that prevents creditors from seizing a foreign sovereign's property to satisfy a court judgment, even after the sovereign has been found liable. This is separate from and often narrower than jurisdictional immunity.
Executive Authority
The constitutional and statutory powers vested in the President and executive branch agencies to enforce laws, conduct foreign relations, and manage government operations. The scope of this authority is defined by the Constitution and statutes passed by Congress.
Exigent Circumstances
A broader exception to the warrant requirement that permits warrantless searches or entries when there are urgent circumstances that make obtaining a warrant impractical, such as hot pursuit of a suspect, destruction of evidence, or an immediate threat to life. The emergency aid exception is a specific type of exigent circumstance.
Express preemption
Preemption that occurs when a federal statute explicitly states that it preempts state law or when Congress directly defines the extent to which its enactments preempt state law. This is the clearest form of preemption and requires the least judicial inference.
Expressio unius
A Latin legal principle meaning 'the expression of one thing implies the exclusion of others.' When a statute explicitly mentions one limitation, the inference is that Congress did not intend other unmentioned limitations to apply. This canon of statutory construction is used to argue against reading additional restrictions into a law.
Expropriation
The act of a government taking private property for public use or state purposes, typically requiring compensation under international law. When done without adequate compensation, it constitutes an unlawful confiscation.
Extraordinary and compelling reasons
The statutory standard under Section 3582(c)(1)(A) that must be met before a court can reduce a federal prisoner's sentence. Congress did not define the phrase specifically but delegated to the Sentencing Commission to provide guidance. The phrase sets a deliberately high bar for relief.
Extraterritorial
Occurring or having effect outside the territorial boundaries of a state or nation. In the context of jurisdiction, extraterritorial refers to a court exercising authority over conduct, persons, or events located beyond its geographic borders. Courts generally have limited extraterritorial reach and must satisfy constitutional and statutory limits on their authority.
Extraterritorial Application
The extension of a nation's laws to conduct occurring outside its borders or involving foreign nationals. In criminal law, extraterritorial application raises questions about whether a federal statute applies to crimes committed in foreign countries.
FAAAA (Federal Aviation Administration Authorization Act of 1994)
A federal law that deregulated the trucking industry and prohibited states from enacting or enforcing any law 'related to a price, route, or service' of motor carriers or freight brokers. It was modeled on the earlier Airline Deregulation Act to create a uniform national market for trucking.
Facial Challenge
A lawsuit arguing that a law or regulation is broadly invalid in all or most of its applications, rather than only unlawful in a specific case. Facial challenges are difficult to win because the challenger must show the law fails generally, not just in one marginal instance.
Facial sex classification
A law that explicitly uses sex as a basis for treating people differently on the text of the statute itself, as opposed to a law that is neutral on its face but has a discriminatory effect or purpose.
Failure-to-warn
A type of product liability claim alleging that a manufacturer negligently or strictly failed to provide adequate warnings or instructions about a product's risks or dangers. The claim does not challenge the product's design itself but rather the sufficiency of information provided to users about hazards.
Favorable termination
Under Heck, the requirement that a plaintiff's criminal conviction must first be reversed, expunged, or otherwise invalidated before the plaintiff can bring a Section 1983 suit that would imply the conviction was wrongful. This ensures federal civil courts don't undermine valid state criminal judgments.
Federal Acquisition Regulations (FAR)
The primary set of rules governing how the federal government purchases goods and services from private contractors. These regulations dictate what costs contractors can include in their bids and what expenses the government will reimburse, including restrictions on litigation-related costs.
Federal Arbitration Act (FAA)
A federal law passed in 1925 that generally requires courts to enforce arbitration agreements in contracts. It reflects a strong national policy favoring the resolution of disputes through private arbitration rather than in court.
Federal common law
Judge-made legal rules created by federal courts to govern areas of uniquely federal concern where Congress has not legislated. Unlike state common law, it derives its authority from the federal government's constitutional responsibilities rather than state sovereignty.
Federal Habeas Corpus
A legal procedure allowing state prisoners to challenge their convictions or sentences in federal court by arguing that their imprisonment violates the U.S. Constitution or federal law. Federal courts can only grant habeas relief for violations of federal law, not state law.
Federal Officer Removal Act
A federal statute (28 U.S.C. § 1442) that allows certain persons—including federal officers, agencies, and those 'acting under' them—to move (remove) lawsuits filed against them in state court to federal court. It exists to protect federal operations from interference by potentially hostile state courts.
Federal Preemption
When federal law overrides or displaces state law under the Supremacy Clause of the Constitution, preventing states from enforcing their own rules on the same subject. Preemption can be explicit (stated in the statute) or implied by the structure and purpose of federal law.
Federal Question Jurisdiction
The authority of federal courts to hear cases involving claims arising under the U.S. Constitution, federal statutes, or treaties. Federal question jurisdiction allows federal courts to hear criminal prosecutions involving alleged violations of federal law.
Federal Tort Claims Act (FTCA)
A federal law enacted in 1946 that waives the United States' sovereign immunity and allows people to sue the federal government for injuries caused by the negligent or wrongful acts of government employees acting within the scope of their employment. It contains numerous exceptions where immunity is preserved.
Federalism
The constitutional system by which power is divided between the federal government and the states. Disputes about federalism arise when there is disagreement about whether the federal or state government has authority over a particular matter. This case raises federalism questions about whether states may enforce federal constitutional eligibility requirements.
Fee simple
The most complete form of property ownership, giving the holder full and permanent rights to the property with no time limit or conditions. It represents the entire 'bundle of rights' in a property.
Fiduciary Duty
A legal obligation to act in the best interest of another person, rather than in one's own interest. Investment advisers typically owe fiduciary duties to their clients. The scope of who qualifies as an 'investment adviser' determines who owes such duties under federal law.
Field preemption
A form of preemption where the federal government is understood to occupy an entire area of regulation so completely that no room remains for state law to operate — regardless of whether any specific state law actually conflicts with federal policy.
FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)
A comprehensive federal statute that grants the EPA authority to regulate pesticide registration, labeling, and use. Under FIFRA, manufacturers must obtain EPA approval for pesticide labels before marketing products, and the EPA sets mandatory labeling requirements that manufacturers must follow.
Fifth Amendment
A provision of the U.S. Constitution that protects individuals in criminal proceedings in several ways, including the right against self-incrimination (the right to remain silent) and the protection against double jeopardy (being tried twice for the same crime).
Final Judgment Rule (28 U.S.C. § 1291)
The general federal rule that courts of appeals may only review 'final decisions' of district courts — meaning a party normally must wait until the entire case is over before appealing any ruling. The collateral order doctrine is a narrow exception to this rule.
Finding of fact
A determination about what actually happened — who did what, when, and where. Under Section 1252(b)(4), findings of fact by the agency are conclusive if supported by reasonable, substantial, and probative evidence from the record. The central dispute in this case is whether the persecution determination is a 'finding of fact' or something else.
First Step Act of 2018
A bipartisan federal criminal justice reform law that, among other things, amended Section 3582 to allow prisoners themselves to file motions for compassionate release directly with the court, rather than relying solely on the Bureau of Prisons to initiate such motions. Congress enacted it because the BOP was filing too few compassionate release motions.
For-cause removal
A statutory restriction meaning the president can only fire an official for a specific reason (cause) rather than at will. The central dispute in this case is what 'cause' means—whether it is as broad as any misconduct or as narrow as inefficiency, neglect, or malfeasance.
For-cause removal protection
A statutory restriction that prevents the President from firing an officer except for specific reasons such as inefficiency, neglect of duty, or malfeasance. This contrasts with 'at-will' removal, where the President can fire someone for any reason or no reason at all.
Foreign adversary
A foreign nation formally designated by the U.S. government as posing a significant threat to national security. The Act applied specifically to applications controlled by entities in foreign adversary nations, with China being the primary target.
Foreign Claims Settlement Commission (FCSC)
A quasi-judicial federal agency within the Department of Justice that adjudicates claims of U.S. nationals against foreign governments for property losses. Its determinations of law and fact are final, conclusive, and not subject to judicial review.
Foreign Relations Deference
A judicial doctrine that courts should defer to the executive branch on matters affecting international relations and foreign policy. Courts recognize that federal courts' jurisdiction and discovery orders affecting foreign nationals can implicate sensitive diplomacy and that international comity (respect for other nations' sovereignty) may limit judicial authority in transnational cases.
Foreign Sovereign Immunities Act (FSIA)
A 1976 federal law that provides the exclusive framework for determining when foreign governments and their agencies can be sued in U.S. courts. It generally grants immunity unless specific exceptions apply, such as commercial activity in the U.S.
Forum Shopping
The practice of choosing between available courts — such as federal versus state court — based on which has more favorable rules or procedures. The Erie doctrine and Hanna analysis are designed in part to discourage forum shopping by ensuring substantially similar outcomes regardless of which court hears a diversity case.
Fourteenth Amendment, Section 3
A provision adopted in 1868 that disqualifies from federal office persons who previously took an oath to support the Constitution and then engaged in insurrection or rebellion. The provision states that such persons cannot hold office unless Congress removes the disability by a two-thirds majority. This section is the focus of the entire case.
Fourth Amendment
The constitutional protection against unreasonable searches and seizures by the government. It requires that searches be reasonable and typically be supported by a warrant issued upon probable cause. The Fourth Amendment protects privacy interests in people, places, and their possessions.
Frame or Receiver
The principal structural component of a firearm — the housing that contains the firing mechanism (trigger, hammer) and sealing components that direct a bullet out the barrel. Under the Gun Control Act, the frame or receiver is the legally regulated 'backbone' of a gun; all other parts attach to it.
Fraudulent Joinder
A legal doctrine that allows a defendant to remove a case to federal court by arguing that a non-diverse co-defendant was joined solely to defeat diversity jurisdiction, not because the plaintiff has a legitimate claim against them. If the court agrees, the non-diverse defendant is dismissed and the case stays in federal court.
Freight Broker
A person or company that acts as a middleman to arrange transportation of goods between shippers (who need cargo moved) and motor carriers (trucking companies) for a fee. Brokers do not typically own trucks or directly employ drivers.
Fresh Start
A fundamental goal of bankruptcy law: to give honest debtors a clean financial slate free from crushing debt, allowing them to rebuild their lives. Courts often cite this principle when deciding how broadly or narrowly to apply bankruptcy rules that affect debtors' ability to keep post-bankruptcy assets.
Fugitive tolling
A doctrine under which the clock on a legal period (such as a sentence or supervision term) stops running when the person subject to it flees or hides from authorities. The time spent as a fugitive does not count toward completing the term, effectively extending it.
Gender dysphoria
A recognized medical condition involving significant distress or impairment caused by a disconnect between a person's gender identity and their sex assigned at birth. It is listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Generalized grievance
A complaint shared broadly by the public at large rather than being specific to the plaintiff. Courts generally refuse to hear cases based on generalized grievances because allowing them would turn courts into forums for abstract policy disputes rather than resolution of concrete harms.
Generic Drug
A medication produced after a brand-name drug's patent expires that contains the same active ingredients and has the same therapeutic effect as the brand-name drug. Generics are typically less expensive and must meet FDA approval standards.
Ghost Gun
A privately made firearm lacking a serial number, making it untraceable by law enforcement. Ghost guns are typically built from parts kits or home-machined components, allowing buyers to bypass background checks and record-keeping requirements that apply to commercially sold firearms.
Gingles Preconditions
Three threshold requirements a plaintiff must meet to establish a Section 2 vote dilution claim: (1) the minority group is sufficiently large and geographically compact to form a majority in a reasonably configured district, (2) the minority group is politically cohesive, and (3) the white majority votes as a bloc to usually defeat minority-preferred candidates.
Habeas corpus
A legal procedure allowing a person in government custody to challenge the legality of their detention. It is the traditional remedy for prisoners who believe their conviction or sentence is unlawful. Heck sought to prevent plaintiffs from using Section 1983 as an end-run around habeas procedures.
Hanna Analysis (Direct Conflict)
The test from Hanna v. Plumer for resolving clashes between federal rules and state law. When a valid Federal Rule of Civil Procedure directly conflicts with — or 'answers the same question as' — a state law, the federal rule controls in federal court. This avoids the more complex Erie balancing test.
Hatch-Waxman Framework
The regulatory and statutory framework under the Drug Price Competition and Patent Term Restoration Act that allows generic drugs to be approved through an abbreviated pathway while preserving patent protections for branded drugs. It establishes procedures for patent disputes when generics seek approval.
Heck bar
A rule from Heck v. Humphrey that prevents someone from bringing a Section 1983 civil rights lawsuit if winning that lawsuit would necessarily call into question the validity of an existing criminal conviction. The plaintiff must first get the conviction overturned through other legal channels.
Heightened scrutiny
A more demanding standard of judicial review that requires the government to show that a challenged law serves an important governmental interest and that the classification drawn by the law is substantially related to achieving that interest. It is stricter than rational basis review but less demanding than strict scrutiny.
Historical analog
An old law or regulation that a government points to as evidence that a modern regulation is consistent with the nation's historical tradition. Under Bruen, the government must identify sufficiently similar historical laws to justify a modern firearms regulation.
Historical Analogue
Under the Bruen test, a founding-era law that is 'relevantly similar' to a modern gun regulation in its burden on the right to bear arms and its underlying justification. The government must produce such analogues to defend modern firearms restrictions.
Historical Tradition Test (Bruen Test)
The legal standard established in New York State Rifle & Pistol Association v. Bruen (2022) requiring the government to show that a modern firearms regulation is consistent with the historical tradition of gun regulation in America at the time of the founding. Courts may not simply balance public safety interests against gun rights; they must find historical analogues.
IEEPA (International Emergency Economic Powers Act)
A 1977 federal law that gives the President authority to regulate economic transactions during declared national emergencies arising from foreign threats. It allows actions like freezing assets, blocking transactions, and regulating imports/exports when the President declares an unusual and extraordinary threat from abroad.
IIRIRA (Illegal Immigration Reform and Immigrant Responsibility Act of 1996)
A major federal law that overhauled immigration enforcement and significantly restricted judicial review of immigration decisions. It codified standards of review for immigration cases and generally limited the ability of courts to override agency determinations.
Illustrative Map
A hypothetical redistricting map drawn by plaintiffs in a Section 2 case to demonstrate that a reasonably configured majority-minority district is possible, satisfying the first Gingles precondition. It is not the final remedy but a tool for proving the violation exists.
Immutability
In equal protection analysis, one factor courts consider when deciding whether a classification deserves heightened judicial protection is whether the characteristic in question is immutable — meaning it is unchangeable or so fundamental to identity that a person should not be required to change it.
Impermissible coaching
As defined by the petitioner, this is the narrow category of conduct where a lawyer attempts to change the substance of a witness's testimony—essentially trying to get the witness to say something the witness does not believe to be true. Distinguished from legitimate witness preparation.
Implied license (implied consent)
A legal concept where a property owner is presumed to have given permission for certain activities simply by opening their property to the public, without needing to say so explicitly. For example, a store that opens its doors is implicitly inviting customers to enter.
Implied preemption
Preemption that is inferred from federal law even when not explicitly stated, typically when state law conflicts with federal law's objectives or purposes, or when federal law is so comprehensive that Congress intended to occupy the entire regulatory field and preclude state law from operating in that area.
Implied private right of action
A right to sue that is not explicitly stated in a statute but is inferred by courts from the statute's language, structure, and purpose. Modern Supreme Court doctrine requires strong textual evidence that Congress intended to create such a right.
Implied repeal
A legal doctrine where a later statute is interpreted as impliedly revoking or limiting an earlier statute, even though the later statute does not expressly say so. Courts strongly disfavor finding implied repeals, typically requiring a strict showing that the two statutes are irreconcilably inconsistent.
In Camera Review
A judicial proceeding where a judge privately examines documents or evidence that are not disclosed to the parties or the public. This allows the judge to make determinations about privileged or sealed materials without revealing them.
In Forma Pauperis
A legal procedure allowing a party without sufficient funds to proceed in court without paying filing fees and costs. The Court may grant in forma pauperis status to indigent litigants to ensure access to the justice system.
Independent agency
A federal agency whose leaders cannot be fired by the President at will, typically structured as a multi-member commission with staggered terms and bipartisan membership requirements. Examples include the FTC, FCC, SEC, and NLRB.
Independent Contractor
A person who provides services to a company but is not classified as an employee. Independent contractors typically do not receive employee benefits, overtime pay, or other legal protections that employees have, but they have more control over how they perform their work.
Individual capacity suit
A lawsuit against a government official in their personal capacity, seeking to hold them personally liable for their actions. Unlike an official capacity suit (which is really against the government entity), an individual capacity suit targets the person and their personal assets. The primary remedy in individual capacity suits is money damages.
Inducement
A form of secondary liability where someone actively encourages, promotes, or persuades another to engage in unlawful conduct. In copyright, this means distributing a product or service with the specific object of promoting its use for infringement, often shown through advertising or direct communication.
Ineffective assistance of counsel
A violation of the Sixth Amendment right to counsel occurring when a defendant's attorney fails to provide competent representation, measured by whether counsel's performance fell below an objective standard of reasonableness and whether this deficient performance caused prejudicial harm to the defense.
Injunctive Relief
A court order requiring a party to stop or refrain from an action (negative injunction) or to take an affirmative action (positive injunction). In patent cases, a successful patent holder may seek an injunction to prevent a competitor from making, using, or selling the patented product.
Injury in fact
A concrete, particularized, and actual or imminent harm to a legally protected interest. This is the first and most contested element of standing in this case — the plaintiff must show they are personally affected, not just generally unhappy about a law.
INM (Inefficiency, Neglect, or Malfeasance)
A specific standard for removing government officials that stands for inefficiency, neglect of duty, or malfeasance in office. It is generally understood to apply only to conduct while in office and to require notice and a hearing before removal.
Institutional Liability
The legal responsibility of a healthcare institution (such as a hospital or medical system) for injuries to patients, which may arise independently from the negligence of individual physicians or staff. Institutional liability recognizes that organizations have their own duties regarding credentialing, supervision, quality assurance, and safe operations.
Instrumentalities (of a foreign state)
Entities that are owned or controlled by a foreign government, such as state-run companies. Under the FSIA, they receive the same immunity as foreign states themselves, unless exceptions apply.
Insurrection
A violent uprising against the authority of the government or state. Section 3 of the Fourteenth Amendment disqualifies from federal office persons who have engaged in insurrection or rebellion against the United States. The precise meaning of insurrection—whether it requires violence, formal organization, or direct participation—is disputed in this case.
Intellectual Disability (Atkins Claim)
A condition characterized by significant limitations in intellectual functioning and adaptive behavior, which under Atkins v. Virginia exempts a person from the death penalty. Establishing intellectual disability typically requires showing below-average IQ, deficits in adaptive functioning, and onset before age 18.
Intentional Infliction of Emotional Distress (IIED)
A tort claim where a plaintiff alleges that a defendant's extreme and outrageous intentional or reckless conduct caused the plaintiff severe emotional distress. It requires more than ordinary rudeness or insensitivity.
Interlocutory Appeal
An appeal taken before a final judgment is entered in a case. Normally, parties must wait until the case is fully resolved before appealing, but certain important rulings can be appealed immediately under specific procedural rules.
Intermediate scrutiny
A middle level of judicial review applied to laws that incidentally burden speech or are content-neutral. The government must show the law serves a substantial government interest and is reasonably — though not necessarily the least restrictive — means of achieving it.
Interstate Commerce
The buying, selling, or movement of goods and services across state lines. The Constitution gives Congress broad power to regulate interstate commerce, and many federal laws apply to workers or businesses involved in it.
Investment Adviser
Under the Investment Advisers Act of 1940, a person or entity that, for compensation, engages in the business of advising others on the advisability of investing in or purchasing securities. The definition is central to determining SEC jurisdiction and regulatory authority over financial advisory activities.
Irreparable harm
An injury that cannot be adequately compensated by money damages after the fact. Courts require a showing of irreparable harm before granting emergency relief like preliminary injunctions. First Amendment violations are often presumed to cause irreparable harm.
Issue Preclusion (Collateral Estoppel)
A doctrine that prevents a party from relitigating an issue that was already decided in a prior proceeding. Non-mutual issue preclusion can sometimes be used by a party who was not involved in the original case to prevent relitigation.
Javits Amendment
A 1974 amendment to Title IX that directed the Department of Health, Education, and Welfare (HEW) to issue regulations for Title IX's application to intercollegiate athletics, taking into account 'the nature of particular sports.' It authorized the regulatory framework permitting sex-separated sports teams.
Jeopardy Attachment
The point in criminal proceedings at which double jeopardy protections 'kick in' and the government loses its ability to simply restart a case. In a jury trial, jeopardy attaches when the jury is sworn in; in a bench trial, when the first witness is sworn; and in a guilty plea, when the court accepts the plea.
JMOL (Judgment as a Matter of Law)
A court ruling that overrides a jury verdict when no reasonable jury could have reached that conclusion based on the evidence presented. It is a legal determination that the evidence is so one-sided that the case should not have gone to the jury or the jury's conclusion cannot stand.
Joint fundraising committee
A committee established by multiple political entities (such as a candidate's campaign, the national party, and state parties) to raise money together. A single donor can write one large check that is then divided among all participating committees according to a pre-set allocation formula, effectively allowing much larger individual donations than any single committee could accept.
Judicial Review
The power of courts to examine government actions and determine whether they comply with law and the Constitution. The scope of judicial review over executive decisions varies based on the type of decision and applicable legal standards.
Jurisdiction Stripping
When Congress passes a law that takes away — or 'strips' — federal courts' power to hear certain types of cases or review certain government decisions, especially in immigration law.
Jury venire
The pool of prospective jurors summoned to court from which jurors are selected for a particular trial. Both the prosecution and defense have the opportunity to examine and challenge prospective jurors during a process called voir dire.
Just Compensation
The 'fair market value' payment the government must provide when it takes someone's property under the Takings Clause. It is generally measured by what a willing buyer would pay a willing seller for the property in an open market.
Laches
An equitable defense that bars a claim when a party has unreasonably delayed in asserting its rights, and that delay has caused prejudice to the opposing party. It functions similarly to a statute of limitations but is more flexible and based on fairness considerations.
Last-Mile Delivery
The final step in a supply chain, where goods are transported from a local warehouse or distribution center to their final destination—typically a store or a customer's home. This is a concept central to the debate over which delivery workers qualify for the FAA exemption.
Legislative Veto
A mechanism allowing one or both houses of Congress to override or cancel an executive action without passing a new law or obtaining the President's signature. The Supreme Court struck down legislative vetoes as unconstitutional in INS v. Chadha (1983), removing what had been IEEPA's primary congressional check on presidential emergency powers.
Less restrictive alternative
Under strict scrutiny, the government cannot justify a speech restriction if another available method would achieve the same compelling interest while burdening speech less. The existence of a viable less restrictive alternative is often fatal to a law under strict scrutiny.
Lesser-included offense
A crime whose elements are all contained within a more serious crime, such that you cannot commit the greater offense without also committing the lesser one. When one offense is a lesser-included offense of another, they are considered the 'same offense' under the Blockburger test.
Level of generality
The degree of abstraction at which a court compares a modern law to historical analogs. Too high a level makes any law seem historically supported; too low requires an exact historical twin. Rahimi clarified that courts should look for analogous principles, not identical laws.
Major Questions Doctrine
A legal principle that courts should not interpret vague or general statutory language as granting agencies or the executive extraordinary powers of vast economic and political significance unless Congress has clearly authorized that specific power. It requires clear congressional authorization for major policy decisions.
Mandamus
A court order compelling a government official to perform a mandatory or ministerial duty. Historically the remedy used by courts of law to reinstate wrongfully removed officers, it requires the person seeking it to show a clear and indisputable right to relief.
Mandatory Arbitration
A requirement, usually written into a contract, that disputes must be resolved through private arbitration rather than in court. Arbitration is a private process where a neutral third party decides the outcome, and the decision is usually final and hard to appeal.
Mandatory minimum
A legally required minimum prison sentence that a judge must impose upon conviction, regardless of other circumstances. Section 924(c) currently carries a mandatory minimum of five years for simple gun possession during a crime of violence, while § 924(j) has no mandatory minimum.
Mandatory minimum sentence
A sentencing floor set by Congress requiring that a convicted person serve at least a specified minimum prison term, regardless of any mitigating circumstances. Judges have very limited discretion to sentence below a mandatory minimum.
Mandatory Victims Restitution Act (MVRA)
A 1996 federal statute that requires courts to order defendants convicted of certain crimes to pay full restitution to their victims. Unlike its predecessor, the VWPA, the MVRA removes judicial discretion over whether and how much restitution to impose, making full victim compensation mandatory.
Master of the Complaint
The principle that a plaintiff has the right to decide whom to sue, what claims to bring, and where to file the lawsuit. This means a plaintiff can structure a case to stay in state court by, for example, including a non-diverse defendant.
Material contribution
A theory of contributory liability where a defendant provides significant, tangible assistance to a primary wrongdoer's illegal conduct. In copyright, this typically means providing the actual tools or means by which infringement occurs, as opposed to merely being aware of it.
Means-ends scrutiny
A method of judicial review that evaluates whether a law's restrictions are proportionate to and effective at achieving the government's stated goals. Bruen explicitly rejected this approach for Second Amendment cases in favor of the historical-tradition test.
Measurement Date (Valuation Date)
The specific date as of which the plan's financial condition is assessed for purposes of calculating withdrawal liability. Under Section 1391, this is the last day of the plan year preceding the year in which the employer withdraws. All parties agree the objective financial data must be measured as of this date; the dispute is whether actuarial assumptions must also be selected by this date.
Medical Malpractice
A form of professional negligence in which a healthcare provider fails to provide care that meets the standard of care expected of reasonably skilled professionals in the field, resulting in injury to the patient. Medical malpractice typically requires proof of a duty of care, breach of that duty, causation, and damages.
Mendoza-Martinez test
A two-step framework from Kennedy v. Mendoza-Martinez used to determine if a government action constitutes criminal punishment. Step 1 asks whether Congress intended to impose punishment through statutory construction. Step 2, reached only if step 1 is ambiguous, examines whether the measure is so punitive in purpose or effect that it must be deemed criminal regardless of Congress's label.
Mens Rea
Latin for 'guilty mind' — the mental state or intent a person must have to be convicted of a crime. Different crimes require different levels of culpability, ranging from negligence to recklessness to knowledge to specific intent or willfulness.
Metadata
Information about communications rather than the content of communications themselves, such as phone numbers called, email addresses contacted, or the time and duration of communications. Metadata can reveal sensitive personal information including location, habits, and associations, even without disclosing the actual content of messages.
Metering (or Turnbacks)
An informal border enforcement practice where U.S. immigration officers limit or stop the number of asylum seekers who can present themselves at a port of entry on a given day, sometimes by telling them to wait or by physically preventing them from approaching.
Minimum Contacts
The legal standard established in International Shoe v. Washington for determining whether a court has personal jurisdiction over a defendant. A defendant must have certain minimum contacts with the forum state such that exercise of jurisdiction does not offend traditional notions of fair play and substantial justice. These contacts can be physical presence, business operations, or other connections to the state.
Miscarriage (of mail)
A term used in the postal exception meaning, at minimum, the failure of mail to arrive at its intended destination or to be carried properly. The parties dispute whether it covers only negligent failures or also intentional wrongful conduct by postal employees.
Mixed question of law and fact
A question that requires applying a legal standard to a set of facts. It is neither purely legal (what does the law say?) nor purely factual (what happened?) but involves both — determining whether what happened satisfies what the law requires.
Mootness
A legal doctrine holding that a case must be dismissed if the controversy has been resolved or the plaintiff no longer faces any real threat of harm. Unlike standing (which looks at whether a case was proper when filed), mootness asks whether the dispute is still live.
Motion to dismiss
An early-stage request by the defendant asking the court to throw out the case without a trial, often because the plaintiff's complaint fails to state a valid legal claim or, as here, because the plaintiff lacks standing. At this stage, courts generally accept the plaintiff's factual allegations as true.
MPPAA (Multiemployer Pension Plan Amendments Act)
A 1980 federal law that amended ERISA to impose withdrawal liability on employers leaving multiemployer pension plans. Before the MPPAA, employers could leave plans without financial consequence, threatening the plans' solvency. The Act created the framework for calculating, assessing, and collecting withdrawal liability that is at issue in this case.
Multiemployer Pension Plan
A pension plan maintained under collective bargaining agreements involving multiple unrelated employers, typically in a single industry. Multiple companies contribute to a shared fund that pays retirement benefits to workers. When one employer leaves, the remaining employers bear a greater share of the plan's obligations, which is why withdrawal liability exists.
Necessarily implies the invalidity
The key test from Heck v. Humphrey: a Section 1983 claim is barred if a judgment in the plaintiff's favor would logically require the conclusion that the plaintiff's existing criminal conviction was wrongful. The parties sharply disagreed on whether prospective relief meets this test.
Necessary and Proper Clause
A constitutional provision (Article I, Section 8, Clause 18) that gives Congress the power to enact laws that are necessary and proper to carry out its other enumerated powers. In this case, it is invoked as a basis for Congress to enforce Spending Clause conditions against individuals who are not direct recipients of federal funds.
Necessity Defense
A common law defense to trespass or other torts, allowing a person to enter another's property without permission when reasonably necessary to prevent serious harm. Justice Gorsuch raised it as a historical analog for the emergency aid exception, noting that private citizens historically could enter homes to save lives.
Negligence
A legal cause of action that requires proof of four elements: (1) a duty of care owed to the plaintiff, (2) breach of that duty, (3) causation (both actual and proximate), and (4) damages resulting from the breach. Negligence is a tort that allows injured parties to recover compensation for losses caused by another's failure to exercise reasonable care.
Negligent Hiring / Negligent Selection
A common-law tort theory holding that a person or company can be liable for harm caused by a contractor or employee if they failed to exercise reasonable care in selecting that contractor, especially when the work involves foreseeable risk of harm to others.
Non-feasance vs. misfeasance
Non-feasance means failing to act or take steps when one arguably should, while misfeasance means taking an affirmative wrongful action. Courts generally distinguish between passively doing nothing (non-feasance) and actively doing something harmful (misfeasance), with secondary liability typically requiring the latter.
Non-self-executing subpoena
An administrative subpoena that does not, by itself, impose any legal obligation or penalty on the recipient. The issuing authority must go to court and obtain a separate order before the recipient can be compelled to comply or face consequences.
Nondelegation Doctrine
A constitutional principle holding that Congress cannot hand off its legislative powers to the executive branch without providing an 'intelligible principle' to guide and constrain the exercise of that delegated authority. It prevents Congress from abdicating its lawmaking responsibility.
Noscitur a sociis
A Latin phrase meaning 'a word is known by the company it keeps.' It is a rule of statutory interpretation holding that the meaning of an ambiguous word should be determined by looking at the other words surrounding it in the statute.
Notice Pleading
The system established by the Federal Rules of Civil Procedure (particularly Rules 8 and 9) requiring only a short, plain statement of the claim to start a lawsuit. The plaintiff need not prove the case at the outset — detailed facts emerge later through discovery.
Object of the regulation
The person or entity that a law is primarily directed at or aimed at regulating. When someone is the direct object of a regulation, courts generally presume they can challenge it without an elaborate showing of injury because the law's impact on them is obvious and direct.
Objectively Reasonable Basis
The standard articulated in Brigham City v. Stuart for emergency aid entries, requiring that an officer's belief that someone inside needs immediate help be grounded in objective facts that a reasonable person would find persuasive, rather than being based solely on the officer's subjective hunches or feelings.
Obscene as to minors
A legal category of sexually explicit material that states may regulate for children even though the same material is constitutionally protected for adults. Material is obscene as to minors if it appeals to prurient interest for minors, is patently offensive for their age group, and lacks serious value for them—even if it would not be obscene for adults.
Off-label use
The practice of prescribing an FDA-approved medication for a purpose, age group, or dosage other than those specifically approved by the FDA. This is legal and extremely common in medicine, especially in pediatrics.
Old soil argument
An interpretive approach arguing that when Congress uses a legal term with an established meaning in existing law (the 'old soil'), it incorporates that established meaning into the new statute. The party making this argument bears the burden of showing the meaning was well-settled.
One-Low-Score Rule
The approach—which both parties agree is incorrect—under which a defendant automatically satisfies the first prong of an intellectual disability claim (below-average intellectual functioning) simply by having one IQ test score whose standard error of measurement range dips below 70, regardless of other scores.
One-Way Ratchet
A structural problem in delegation law where once Congress grants power to the President, it becomes practically impossible to reclaim because the President can veto any legislation to take it back, requiring a two-thirds supermajority in both chambers to override.
Original Jurisdiction
The authority of the U.S. Supreme Court to hear certain cases directly, without them first being tried in a lower court. The Constitution grants the Supreme Court original jurisdiction over disputes between states, which is relevant when determining whether a state entity is really the state itself.
Overinclusive and underinclusive
A law is overinclusive when it covers more people or situations than necessary to achieve its purpose, and underinclusive when it fails to cover people or situations that present the same concerns. Both are relevant when courts evaluate whether a law is properly tailored to its stated goals.
Parole
The early release of a prisoner from incarceration, subject to conditions and supervision for the remainder of the original sentence. Federal parole was abolished prospectively by the Sentencing Reform Act of 1984, though legacy parole cases still exist. Unlike supervised release, parole is carved out of the prison sentence rather than added on top of it.
Past persecution
A showing that an asylum applicant suffered persecution in their home country before coming to the United States. If established, it creates a presumption that the applicant is eligible for asylum without needing to separately prove a forward-looking fear of future persecution.
Patent Claims
The specific language at the end of a patent document that defines the scope and boundaries of what the patent protects. Claims are written in technical language and determine what others cannot make, use, or sell without permission.
Patent Infringement
The unauthorized making, using, offering to sell, or selling of a patented invention during the patent term. In patent law, a party infringes if it makes, uses, or sells a product or process covered by a valid patent claim without permission.
Patent Validity
Whether a patent meets all statutory requirements for patentability, including novelty, non-obviousness, and adequate disclosure. A valid patent entitles the holder to exclusive rights; an invalid patent may not be enforced.
Pennhurst Doctrine
A rule from the Supreme Court's decision in Pennhurst State School v. Halderman holding that federal courts cannot order state officials to comply with state law when the state has sovereign immunity. It limits the types of claims that can be brought against state entities in federal court.
Peremptory strike
A lawyer's right to remove a potential juror from the jury panel without stating a reason and without the judge's approval. Traditionally, peremptory strikes were exercised at a lawyer's complete discretion, but modern law limits their use to prevent race-based or other unconstitutional discrimination.
Persecution
A legal standard under immigration law meaning extreme suffering or harm inflicted on account of a protected characteristic (race, religion, nationality, political opinion, or membership in a particular social group). Courts have broadly agreed it must amount to more than ordinary harassment or mistreatment.
Personal jurisdiction
A court's legal authority over a particular person or entity. For a court to enter a valid judgment against someone, it must have personal jurisdiction, which typically requires proper service of process and sufficient connections between the defendant and the forum. Without personal jurisdiction, a judgment may be considered void.
Petroleum Administration for War (PAW)
A federal wartime agency that extensively regulated and supervised oil production, refining, and distribution during World War II to maximize petroleum output for the war effort. It set production targets, regulated drilling practices, and coordinated the supply chain from crude production to refined products.
Plea Agreement
A negotiated deal between a criminal defendant and the prosecutor in which the defendant agrees to plead guilty (usually to reduced charges or for a recommended sentence) in exchange for concessions by the government. Most federal criminal cases are resolved this way.
Pocketbook injury
A financial or monetary harm — the most traditional and easily recognized form of injury for standing purposes. If a law costs you money, that is generally sufficient to establish standing regardless of whether you can prove other harms.
Poison pill (impermissible motive doctrine)
A constitutional principle that when a law is enacted with an impermissible purpose — such as suppressing disfavored speech — that motive can invalidate the entire law, even if the government also had a legitimate secondary purpose.
Port of Entry
An officially designated location — such as a bridge, checkpoint, or airport — where travelers are authorized to enter the United States and where immigration officers process arrivals.
Post-Petition
Anything that happens after a bankruptcy petition (the official document starting a bankruptcy case) is filed with the court. This term is important because the Bankruptcy Code treats property and events before and after the petition filing very differently.
Postal Exception
A provision in the Federal Tort Claims Act (28 U.S.C. § 2680(b)) that preserves the government's sovereign immunity for 'any claim arising out of the loss, miscarriage, or negligent transmission of mail.' It means you cannot sue the government for certain mail-related injuries.
Pre-enforcement challenge
A lawsuit filed to challenge a law before it is actually applied to the plaintiff. In the standing context, courts allow such challenges when there is a credible or non-imaginary threat that the law will be enforced against the challenger, without requiring proof of certain harm.
Pre-enforcement review
A legal challenge to a government action or law before it is actually enforced against the plaintiff. Courts allow such challenges when a plaintiff faces a credible threat of enforcement, so they don't have to violate a law and face prosecution to test its constitutionality.
Preclusion trap
A situation where requiring a plaintiff to litigate in state court first effectively bars them from ever reaching federal court, because the state court judgment will be given preclusive effect (res judicata) that prevents re-litigating the same issues in federal court.
Predicate offense
An underlying crime that must be committed as a prerequisite for another criminal charge. Section 924(c) requires that the gun be used during a 'crime of violence or drug trafficking crime,' which is its predicate offense. Similarly, § 924(j) requires a violation of § 924(c) as its predicate.
Preemption
The constitutional doctrine under which federal law overrides or displaces conflicting state law. It can be express (Congress says so) or implied (federal law so thoroughly occupies a field that state law cannot coexist).
Preliminary injunction
A court order issued before a full trial that temporarily blocks a law or government action while litigation proceeds. To obtain one, a party must show it is likely to succeed on the merits, will suffer irreparable harm without it, and that the balance of hardships and public interest favor relief.
Preponderance of the Evidence
The most common civil burden of proof, requiring that a claim be more likely true than not—essentially, greater than a 50% probability. In Alabama's Atkins proceedings, this means the defendant must show it is more probable than not that his true IQ is 70 or below.
Present Value
The current worth of a future stream of payments, calculated by applying a discount rate to account for the time value of money. A dollar to be paid 30 years from now is worth less than a dollar today, and the present value calculation determines exactly how much less based on the chosen discount rate.
Presidential suspension power
A provision in the Helms-Burton Act allowing the President to suspend the right to bring Title III lawsuits for six months at a time, based on U.S. national interest and promoting a transition to democracy in Cuba.
Presumption Against Extraterritorial Application
A canon of statutory interpretation holding that federal laws are presumed to apply only within U.S. territory unless Congress has clearly expressed intent to extend them abroad. This presumption requires explicit statutory language before courts will interpret a law to reach foreign conduct.
Presumption of Consistent Usage
A principle of statutory interpretation that when Congress uses the same word in different parts of the same statute, it is presumed to mean the same thing in both places, unless context clearly indicates otherwise.
Presumptive ban
A law that defaults to prohibiting an activity unless specific conditions are met to allow it. Here, Hawaii's law presumes that carrying a firearm on private property open to the public is forbidden unless the property owner has given express permission.
Pretext / Pretextual regulation
A law that claims to serve one purpose but is actually designed to achieve a different, often unconstitutional, goal. The U.S. government argued that Hawaii's law claims to protect property rights but is really designed to undermine the Second Amendment right to carry.
Prior restraint
A government action that prevents speech from occurring in the first place, rather than punishing it after the fact. Prior restraints are considered especially disfavored under the First Amendment because they chill speech before it happens.
Probable Cause
A standard of evidence meaning a 'fair probability' or 'substantial chance' that something is true. In criminal law, it typically means a reasonable belief that a crime has been committed. Petitioner argues it should also be required before entering a home to render emergency aid, applied to the likelihood of an emergency rather than a crime.
Procedural waiver
The loss of a legal right or claim because it was not raised at the proper time or in the proper manner during legal proceedings. A party that fails to assert a claim or objection when required to do so may be barred from raising it later.
Prong 1 / Prong 2 (Intellectual Disability)
Many states, including Alabama, analyze intellectual disability claims in distinct parts or 'prongs.' Prong 1 typically addresses intellectual functioning (usually measured by IQ), and Prong 2 addresses adaptive behavior deficits. A defendant must generally satisfy both prongs to be found intellectually disabled.
Prophylactic rule
A legal rule that goes beyond what the Constitution strictly requires in order to provide a clearer, more easily administered standard that prevents constitutional violations. The government described its broader no-testimony-discussion rule as partly prophylactic.
Prosecutorial Discretion
The authority granted to prosecutors and law enforcement to decide whether to initiate charges, pursue enforcement actions, or allocate investigative resources. While broad, this discretion is not absolute and must operate within constitutional and statutory constraints.
Prospective relief
A court remedy that looks forward rather than backward — it prevents future violations rather than compensating for past ones. Common forms include injunctions (court orders to stop doing something) and declaratory judgments (court declarations about what the law means going forward).
Prothonotary
The chief clerk of certain courts, particularly in Delaware and Pennsylvania, responsible for filing and maintaining court records. In Delaware, the prothonotary is the official who receives and dockets complaints.
Puberty blockers
Medications (typically GnRH agonists) that temporarily pause the hormonal changes of puberty. They have been used for decades to treat precocious (early) puberty and are also prescribed to transgender adolescents to delay puberty and give them more time before making decisions about further treatment.
Public Accommodations
Privately owned businesses or facilities that are open to the general public, including hotels, restaurants, stores, entertainment venues, and similar establishments. The Civil Rights Act of 1964 prohibits discrimination in public accommodations based on race, color, religion, or national origin.
Public Corporation
A corporation created by a state to carry out public functions, but structured as a separate legal entity with its own assets, liabilities, and ability to sue and be sued. Unlike a traditional government agency, it has a distinct legal identity separate from the state that created it.
Qualified conferral order
A trial court order that allows a defendant and lawyer to communicate but restricts the topics they may discuss—typically prohibiting discussion of the defendant's ongoing testimony while permitting other trial-related conversations. This is contrasted with an 'absolute' no-contact order.
Qualified divestiture
A specific statutory term in the Act requiring ByteDance to completely sever Chinese government control over TikTok — including control over the algorithm, data, and operations — not merely transfer nominal ownership to a new company.
Qualified immunity
A legal doctrine that protects government officials from personal liability for civil damages unless their conduct violated clearly established law that a reasonable person would have known. It serves as a safety net ensuring officials are not punished for reasonable mistakes about what the law requires.
Quantum meruit
A Latin term meaning 'as much as deserved,' referring to a legal doctrine that allows a party to recover the reasonable value of services or benefits provided to another, even without a valid contract. It prevents unjust enrichment.
Quasi-suspect classification
A classification — like sex or illegitimacy — that the Supreme Court has recognized as deserving more judicial protection than ordinary classifications but less than classifications like race. Laws using quasi-suspect classifications are reviewed under intermediate scrutiny.
Quid pro quo corruption
A direct exchange of something of value (like a campaign contribution) for an official action (like a vote or policy decision). Under current Supreme Court precedent, preventing this type of corruption or its appearance is the only permissible government interest that can justify limits on campaign contributions and spending.
Quo warranto
A legal proceeding used to challenge a person's right to hold a public office. Traditionally used when two people claim the same office, it asks 'by what authority' does the person hold the position.
Racial Predominance
The legal standard under Shaw v. Reno that triggers strict scrutiny of a redistricting plan. Race predominates when it is the factor that could not be compromised and that subordinated traditional race-neutral districting principles like compactness, contiguity, and respect for political subdivisions.
Racially Polarized Voting
A pattern where voters of different races consistently vote for different candidates, such that the preferred candidates of a minority group are regularly defeated by the majority group's bloc voting. It is a critical element of the Gingles test for proving vote dilution under Section 2.
Rational basis review
The most lenient standard of judicial review, under which a law is upheld if it is rationally related to any legitimate government interest. The government does not need to prove its reasoning — courts may even hypothesize justifications. Nearly all laws survive this standard.
Readily Converted
A statutory standard in the Gun Control Act meaning an item can be quickly, easily, and efficiently made into a functional firearm using common tools by a person of ordinary skill. Courts have interpreted this to allow roughly up to eight hours of conversion time, with faster conversions more clearly qualifying.
Real Party in Interest
The person or entity that actually stands to gain or lose from the outcome of a lawsuit, regardless of who is formally named as a party. In sovereign immunity cases, if the state treasury would actually bear the cost of an adverse judgment, the state may be considered the real party in interest even if only the agency is named.
Reasonable expectation of privacy
The legal standard established in Katz v. United States to determine whether a person has Fourth Amendment protection in a particular situation. An expectation of privacy is reasonable if a person subjectively expects privacy and society recognizes that expectation as reasonable. This test applies to new technologies and circumstances not contemplated when the Fourth Amendment was drafted.
Reasonable Suspicion
A lower standard of evidence than probable cause, requiring specific and articulable facts that would lead a reasonable officer to suspect criminal activity. It is the standard for Terry stops (brief investigatory detentions) and is what the Petitioner argued the Montana Supreme Court improperly applied to justify the home entry.
Receipt Deadline
A rule requiring that a mailed ballot physically arrive at election offices by a certain date — typically Election Day — to be counted, regardless of when it was sent or postmarked.
Redemption Period
A window of time given to a property owner to pay off back taxes and reclaim their property before the government can complete a tax foreclosure sale. Redemption periods vary by state and are intended to give owners a fair chance to save their homes.
Regulatory approval
Official authorization or clearance granted by a government agency permitting a product to be manufactured, labeled, marketed, or sold. Regulatory approval establishes that a product complies with applicable legal standards but does not necessarily immunize the product from state law liability.
Regulatory Authority
The power granted by law to an agency to make rules, issue orders, and enforce compliance with those rules in a particular area of law. In this case, the central question is whether the FCC possessed the regulatory authority to issue the challenged telecommunications regulations.
Regulatory Jurisdiction
The lawful authority of a regulatory agency to exercise control over specific persons, entities, or activities within a defined area. Jurisdiction is determined by statute and determines which agency (federal or state, SEC or other body) has authority to regulate particular conduct.
Regulatory labeling
Product warnings, instructions, and disclosures that are required by federal or state regulatory agencies and must appear on product packaging or accompanying materials. Regulatory labeling reflects governmental determinations about what information consumers must receive about product risks.
Regulatory Tariff vs. Revenue-Raising Tariff
A regulatory tariff is imposed primarily to influence behavior — such as discouraging imports or pressuring foreign governments to negotiate — rather than to generate government revenue. A revenue-raising tariff is imposed primarily to collect money for the treasury. The distinction matters because revenue-raising implicates Congress's exclusive taxing power.
Relating to
A broad legal phrase added to the Federal Officer Removal Act in 2011, interpreted by the Supreme Court in other contexts to mean 'connected to' or 'associated with.' It expanded the types of conduct that can support removal beyond acts directly performed under federal authority to include related activities.
Remedies
Legal or equitable relief awarded to a plaintiff who prevails in a lawsuit, such as compensatory damages (money damages for actual losses), punitive damages (additional damages to punish defendant conduct), injunctive relief (court orders to stop or require specific conduct), or other forms of relief designed to make the plaintiff whole or deter future violations.
Removal
The legal process by which a defendant transfers a case filed in state court to federal court. Removal is typically available when the federal court would have had original jurisdiction over the case, such as when there is complete diversity of citizenship.
Res judicata
A legal doctrine meaning 'a matter already judged' that prevents the same parties from relitigating issues that have been finally decided by a court. Even void judgments can have preclusive effect under this doctrine if a party has already had an opportunity to challenge the judgment's validity.
Rescission
A legal remedy that undoes or cancels a contract, returning the parties to the positions they were in before the contract was made. It is an equitable remedy, as opposed to monetary damages.
Restitution
A court-ordered payment by a criminal defendant to compensate victims for losses caused by the defendant's crime. It differs from a fine (which is paid to the government) and from civil damages (which are awarded in a separate lawsuit). Under the MVRA, it is mandatory and covers the full amount of victim losses.
Retroactivity
The principle that a new law applies to conduct or sentences that occurred before the law was enacted. When Congress makes a law retroactive, it applies to people already sentenced; when it makes a law only prospective, it applies only to future cases. Retroactivity decisions are typically key negotiating points in criminal justice legislation.
Revocation
The judicial process of canceling a person's supervised release (or parole or probation) due to a violation of its conditions. Upon revocation, the court can send the person back to prison and may impose a new period of supervised release afterward.
RFRA (Religious Freedom Restoration Act)
A 1993 federal statute that prohibits the federal government from substantially burdening a person's religious exercise unless it demonstrates a compelling interest pursued through the least restrictive means. After the Supreme Court struck down RFRA's application to states in City of Boerne, Congress enacted RLUIPA to restore similar protections in the institutional context using the Spending Clause.
Right to assistance of counsel
The Sixth Amendment guarantee that a criminal defendant has the right to have a lawyer help with their defense. This includes not just having a lawyer present but receiving meaningful legal advice and assistance on trial-related matters.
Right to exclude
A fundamental property right that allows an owner to control who may enter their property and under what conditions. This right is considered one of the most essential aspects of property ownership and was invoked by Hawaii as the basis for requiring express consent.
Right to receive information
A First Amendment principle, established in Lamont v. Postmaster General, protecting Americans' right to receive speech from others — including foreign sources — without government interference based on disagreement with the content.
RLUIPA (Religious Land Use and Institutionalized Persons Act)
A 2000 federal statute that prohibits state and local governments from imposing substantial burdens on the religious exercise of institutionalized persons (primarily prisoners) unless the burden serves a compelling governmental interest and is the least restrictive means. It applies to institutions that receive federal funds.
Rule 54(b) Certification
A federal procedural rule that allows a district court to enter a final, appealable judgment on one or more claims or parties in a multi-party case before all claims are resolved. This permits immediate appellate review of that partial judgment.
Rule 60(b)(4)
A provision of the Federal Rules of Civil Procedure that allows a court to relieve a party from a final judgment if the judgment is 'void.' This is one of several grounds listed in Rule 60(b) for seeking relief from a judgment.
Rule 60(c)(1)
The timing provision of Rule 60 that requires motions for relief under Rule 60(b) to be made within a 'reasonable time.' For motions under subsections (b)(1) through (b)(3), there is also a one-year outer limit. The central dispute in this case is whether the 'reasonable time' requirement applies to 60(b)(4) motions challenging void judgments.
Rule 60(d)
A provision preserving certain additional avenues for relief from judgment outside of Rule 60(b), including independent actions and relief from fraud on the court. Unlike Rule 60(b), Rule 60(d) has no explicit time limit. Respondent argued that if the drafters wanted no time limit for void judgments, they would have placed them under this provision.
Rule of decision
A legal standard that tells courts how to decide a particular issue when it arises in litigation, as opposed to a provision that grants parties the right to initiate litigation. A rule of decision applies once parties are already before the court.
Rule of Lenity
A principle of statutory interpretation holding that ambiguities in criminal statutes should be resolved in favor of the defendant. It is rooted in separation of powers and the presumption of liberty, requiring that Congress speak clearly before criminal punishment is imposed.
Rules Enabling Act
The federal statute that authorizes the Supreme Court to prescribe rules of procedure for federal courts, with the limitation that such rules shall not abridge, enlarge, or modify any substantive right. It is the test for whether a Federal Rule of Civil Procedure is valid.
Russello presumption
A canon of statutory interpretation holding that when Congress uses different language in different parts of the same statute, it is presumed to have done so intentionally and to have meant different things. Named after the 1983 Supreme Court case Russello v. United States.
Safe harbor
A legal provision that protects someone from liability if they follow specified rules or procedures. In regulatory law, a safe harbor gives regulated parties certainty that certain conduct is permissible.
Safe harbor (DMCA Section 512)
A legal protection created by the Digital Millennium Copyright Act that shields Internet Service Providers from copyright liability if they meet certain conditions, such as adopting a policy for terminating repeat infringers and responding to takedown notices. It limits, but does not eliminate, potential liability.
Safety valve
A legal provision designed as a backstop or escape mechanism to prevent unjust outcomes in exceptional cases. In sentencing law, it refers to provisions allowing courts to impose sentences below mandatory minimums or reduce sentences in extraordinary circumstances.
Scope of Authority
The boundaries or limits of the power an agency has been granted by Congress. A question about scope of authority asks whether an agency action falls within or exceeds the power Congress delegated to it.
Sealed Materials
Documents or evidence in a legal case that the court has ordered to be kept confidential and not disclosed to the general public. Sealed materials may contain sensitive personal information, trade secrets, or other information requiring protection, and are accessible only to parties to the litigation and the court.
Second Amendment
The constitutional provision in the Bill of Rights that protects the right of individuals to keep and bear arms. The Supreme Court has confirmed this is an individual right, though its exact scope — particularly who may be disarmed and under what circumstances — remains heavily litigated.
Second or successive application
A habeas corpus petition or motion filed after a prisoner has already had one full round of post-conviction review. Under AEDPA, filing such an application requires special authorization from a court of appeals panel, and the application must meet heightened substantive requirements.
Secondary effects doctrine
A First Amendment doctrine allowing governments to regulate adult businesses based on their non-speech-related impacts on surrounding communities—such as crime or declining property values—without triggering strict scrutiny, because the law targets effects rather than content.
Secondary liability
Legal responsibility imposed on someone who did not directly commit a wrong but facilitated, encouraged, or assisted the primary wrongdoer. In copyright, it includes both contributory infringement and vicarious liability, neither of which is explicitly mentioned in the Copyright Act but has been recognized by courts.
Section 1 Exemption
A provision in the Federal Arbitration Act that excludes certain workers from the law's coverage. Specifically, it exempts 'contracts of employment of seamen, railroad employees, or any other class of workers engaged in foreign or interstate commerce,' meaning those workers can take their disputes to court even if they signed an arbitration agreement.
Section 122 of the Trade Act of 1974
A trade statute that explicitly authorizes the President to impose tariffs to address 'large and serious' trade deficits, but with strict limits: a maximum 15 percent tariff rate and a 150-day time limit. Challengers cited it as evidence that Congress knew how to delegate tariff authority with proper guardrails.
Section 1983
A federal statute (42 U.S.C. § 1983) that allows individuals to sue state officials who violate their federal constitutional or statutory rights while acting 'under color of state law.' It is the primary vehicle for enforcing civil rights against state actors and routinely permits damages suits against individual officials.
Section 2254 application
A federal habeas corpus petition filed by a state prisoner challenging the legality of their state-court conviction or sentence. It allows federal courts to review whether a state prisoner is being held in violation of the Constitution or federal law.
Section 2255 (habeas corpus)
The primary federal post-conviction remedy allowing prisoners to challenge the legality of their conviction or sentence. It has strict procedural requirements including a one-year statute of limitations and severe restrictions on filing second or successive petitions. If a prisoner proves their sentence is unlawful, the court must grant relief.
Section 2255 motion
The primary legal vehicle for federal prisoners to challenge their convictions or sentences after direct appeal. It is a motion filed in the sentencing court, distinct from a habeas corpus application, and functions as the federal counterpart to Section 2254 for state prisoners.
Section 3553(a) factors
A statutory list of factors that federal courts must consider when imposing or modifying a sentence, including the nature of the offense, the defendant's history, the need for deterrence, public safety, and the need to avoid unwarranted sentencing disparities among similarly situated defendants. The compassionate release statute incorporates these factors by reference.
Section 3583(i)
A federal statute enacted in 1994 providing that if a warrant or summons for a supervised release violation is issued before the supervised release term expires, the court retains jurisdiction to conduct a revocation hearing even after the term has ended. It serves as a safety valve for late-in-term violations.
Self-executing constitutional provision
A provision of the Constitution that operates and is enforceable without requiring Congress or other branches to pass implementing legislation. Self-executing provisions create rights and impose duties that individuals and courts can rely upon directly. The question of whether the Fourteenth Amendment's Section 3 is self-executing is central to this case.
Self-executing subpoena
A subpoena that imposes immediate legal obligations and penalties from the moment it is issued, without requiring a separate court order to enforce compliance. Failure to comply can directly trigger penalties.
Self-inflicted injury
A harm that the plaintiff has voluntarily brought upon themselves rather than one caused by the defendant's conduct. Courts are skeptical of self-inflicted injuries as a basis for standing because the plaintiff could have avoided the harm by choosing differently.
Sensitive places
Locations where firearms may be restricted consistent with the Second Amendment because of a historical tradition of limiting weapons there. Heller cited schools and government buildings as examples, and Bruen recognized that the concept has limits to prevent every place from being designated sensitive.
Sentencing Commission
An independent agency within the judicial branch that establishes sentencing guidelines and policies for federal courts. Under Section 994(t), Congress delegated to the Commission the authority to define what constitutes 'extraordinary and compelling reasons' for sentence reductions, and courts must ensure reductions are consistent with the Commission's policy statements.
Sentencing Commission policy statement
Official guidance issued by the U.S. Sentencing Commission that helps courts interpret and apply sentencing laws. Under 28 U.S.C. § 994(t), Congress directed the Commission to describe what constitutes 'extraordinary and compelling reasons' for compassionate release. These policy statements must go before Congress for six months before taking effect, and Congress can reject them.
Sentencing finality
The principle that criminal sentences should be final and not subject to endless relitigation. The Sentencing Reform Act of 1984 emphasized finality by abolishing federal parole and establishing determinate sentencing, while leaving narrow exceptions like compassionate release.
Sentencing guidelines
Advisory ranges established by the U.S. Sentencing Commission that recommend appropriate sentences based on the offense and the defendant's history. In revocation cases, the guidelines assign a 'grade' to the violation, which affects the recommended sentencing range. Courts must give respectful consideration to these ranges but are not bound by them.
Sentencing Reform Act of 1984
A federal law that overhauled the federal sentencing system. It abolished federal parole prospectively, created the supervised release system as a replacement, established the U.S. Sentencing Commission, and introduced federal sentencing guidelines. It governs how federal sentences are structured and served.
Separation of powers
The constitutional principle that legislative, executive, and judicial powers are divided among the three branches of government. In this context, it means that Congress — not the courts — decides what conduct to criminalize and how severely to punish it, so courts should not impose additional punishment without clear congressional authorization.
Sequestration of witnesses
A long-standing trial practice of keeping witnesses separate from each other and from attorneys so that their testimony is not influenced by what others have said. The government cited this tradition as historical support for restricting defendant-counsel communication about testimony.
Seventh Amendment right to jury trial
The constitutional guarantee that in civil cases involving claims for money damages that would have been tried at common law, the parties have a right to a jury trial. The Court has extended this to statutory actions that resemble common law damages claims.
Severability
The legal question of whether an unconstitutional portion of a statute can be removed while leaving the rest of the law intact. In removal cases, this means asking whether striking down the removal restriction saves the agency itself.
Sex-Based Classification
A law or policy that treats people differently based on their biological sex. Under Supreme Court precedent, such classifications trigger intermediate scrutiny and must serve important government interests through substantially related means.
Similarly situated
A legal concept requiring that people must be in comparable circumstances before differential treatment counts as discrimination. If two groups are not similarly situated, treating them differently is a distinction, not discrimination.
Skidmore deference
A standard of judicial respect for agency interpretations of statutes. Under Skidmore v. Swift & Co., courts give weight to an agency's interpretation based on its thoroughness, reasoning, consistency, and other persuasive qualities — less deferential than the now-overruled Chevron deference.
Sliding Scale
The United States' proposed framework suggesting that the amount of information officers need before entering varies with the severity of the threatened harm — more severe threats may justify entry with less corroborating evidence. Justice Gorsuch challenged this concept, noting that Brigham City already fixes the severity at serious injury.
Solicitor General
The government official responsible for representing the United States in cases before the Supreme Court. The Solicitor General decides which cases the government will appeal, how to argue them, and often files briefs in cases where the government has a significant interest even if it is not a direct party.
Sovereign Immunity
The legal doctrine that the government cannot be sued without its consent. The FTCA waives this immunity for certain tort claims, but exceptions like the postal exception preserve it in specific areas.
Speech incidental to conduct
A legal doctrine holding that when speech is merely a secondary part of regulated non-speech activity (conduct), the government can regulate it without triggering full First Amendment scrutiny. The key question is whether there is separate non-speech conduct being regulated.
Spending Clause
Article I, Section 8 of the Constitution, which gives Congress the power to tax and spend for the general welfare. Congress uses this power to attach conditions to federal funding — essentially telling states, 'if you want this money, you must comply with these rules.' The Supreme Court requires that such conditions provide clear notice to the states.
Stacking (Section 924(c))
Under the pre-2018 version of Section 924(c), a defendant convicted of multiple gun offenses in connection with crimes of violence or drug trafficking received mandatory consecutive sentences that 'stacked'—the first offense carried a 5-year minimum, and each additional offense carried a 25-year mandatory consecutive sentence. The First Step Act changed this so the enhanced 25-year minimum applies only after a prior 924(c) conviction has become final.
Standard Error of Measurement (SEM)
A statistical concept reflecting the fact that any single IQ test score is an estimate, not an exact measure, of a person's true intelligence. Because tests are imperfect, a score of 72 with a standard error of ±5 actually represents a range of roughly 67 to 77, meaning the person's true IQ could fall anywhere in that band.
Standard of care
The level of treatment and skill that a reasonably competent healthcare professional in the same field would provide under similar circumstances. It is typically defined by medical consensus and serves as the benchmark in malpractice cases.
Standard of Review
The level of scrutiny a court applies when reviewing lower court or agency decisions. Different standards (de novo, clear error, substantial evidence, arbitrary and capricious) require different degrees of deference to the lower decision-maker. The parties dispute which standard applies to the SEC's statutory interpretation.
Standing
A legal requirement that a person bringing a lawsuit must show they have suffered or will imminently suffer a concrete injury caused by the defendant's actions. In challenges to laws not yet enforced against the plaintiff, there must be a sufficiently credible threat of enforcement.
Staple article of commerce doctrine
A principle borrowed from patent law holding that the seller of a common product capable of both lawful and unlawful uses generally cannot be held liable for a buyer's unlawful use of that product. The rationale is that selling everyday goods shouldn't create liability when the goods have many legitimate uses.
Stare decisis
The legal principle that courts should follow their prior decisions to ensure stability and predictability in the law. Overruling a precedent requires special justification, and courts consider factors like how wrong the decision was, reliance interests, and workability.
State secrets privilege
An evidentiary privilege that allows the government to resist disclosure of information in litigation if revealing it would harm national security. It can result in exclusion of specific evidence or, in extreme cases, dismissal of entire lawsuits.
Status-Based Disarmament
A categorical prohibition on firearms possession based on a person's status or identity — such as being a felon, a drug user, or having a mental illness — rather than on specific dangerous conduct. Many of the § 922(g) prohibitions are status-based, and their constitutionality under the Bruen test is a central issue in this litigation.
Statutory Construction
The process of interpreting the meaning and scope of a statute, including determining its geographic reach and applicability to specific conduct. Courts apply canons of construction, such as the presumption against extraterritorial application, to guide statutory interpretation.
Statutory history
The record of how a statute has been enacted, amended, and evolved over time, distinct from legislative history (committee reports, floor statements). Even judges skeptical of legislative history generally accept looking at prior versions of a statute to understand its current text.
Statutory Interpretation
The process by which courts determine the meaning and scope of a statute. Courts may look to statutory text, legislative history, purpose, and related case law. The proper scope of interpretation—whether courts should defer to agency readings or apply independent judgment—is a central dispute in this case.
Strict scrutiny
The most demanding level of judicial review, applied to laws that burden fundamental constitutional rights or target protected groups. The government must prove the law serves a compelling government interest and is narrowly tailored — using the least restrictive means available — to achieve that interest.
Subject-Matter Jurisdiction
A court's authority to hear a particular type of case based on the nature of the claim or the parties involved. Federal courts have subject-matter jurisdiction over federal questions (claims arising under federal law) and diversity cases (claims between citizens of different states involving amounts exceeding $75,000). A court lacking subject-matter jurisdiction cannot hear a case regardless of personal jurisdiction.
Substantial evidence review
A deferential standard of review where a court will uphold an agency's factual finding as long as a reasonable person could have reached the same conclusion based on the evidence. The court does not substitute its own judgment but only asks whether the agency's conclusion was reasonable.
Substantial Fit
The degree of alignment required between a government classification and its stated objective under intermediate scrutiny. The law must be substantially related to an important interest but need not be perfectly tailored to every individual case.
Substantial risk of harm
The standard used in standing analysis when the alleged injury has not yet occurred. The plaintiff must show that the threatened harm is not merely speculative or theoretical but is sufficiently likely to happen. Courts have not defined a specific probability threshold.
Substitute payor
A concept used by respondent to describe the unusual role the Helms-Burton Act assigns to traffickers: they effectively stand in for the Cuban government as the entity that must pay just compensation for confiscated property. Only those who traffic in the specific confiscated interest can be put in this position.
Sue-and-Be-Sued Clause
A provision in an entity's organic statute that authorizes it to initiate lawsuits and to be sued in its own name. Such clauses are typical of public corporations and suggest the entity has a legal identity separate from the government that created it.
Suicide by Cop
A situation in which a person deliberately provokes a confrontation with law enforcement with the intent of being killed by police, often by threatening officers with a weapon. Officers familiar with Case believed this was his likely intention rather than self-harm, which was central to Petitioner's argument against probable cause.
Summary Judgment
A procedure under Federal Rule 56 where a court decides a case without a full trial because there is no genuine dispute of material fact and one party is entitled to judgment as a matter of law. It can be used to dispose of cases where the evidence is one-sided.
Super PAC
An independent expenditure-only committee that can raise and spend unlimited amounts of money to advocate for or against candidates, as long as it does not coordinate with any candidate's campaign or party. Super PACs emerged after Citizens United and have become major players in elections, often outspending traditional party committees.
Supervised release
A period of court-ordered supervision that follows a federal prison sentence. Unlike parole, it is not a reduction of prison time but an additional period designed to help the person reintegrate into society, during which they must comply with conditions set by the court and report to a probation officer.
Supplemental Jurisdiction
The authority of a federal court to hear additional claims that are related to the claims over which it has original jurisdiction, even if those additional claims would not independently qualify for federal court. Governed by 28 U.S.C. § 1367.
Supremacy Clause
Article VI of the Constitution, which declares that the Constitution, federal statutes, and treaties are the 'supreme law of the land' and override conflicting state laws. It is the textual foundation for all preemption doctrines.
Surplus Equity
The value of a property that exceeds the amount of debt owed on it. In a tax foreclosure, surplus equity is the money left over after the government collects what it is owed in back taxes, penalties, and fees.
Surplusage Canon
A rule of statutory interpretation holding that courts should try to give meaning to every word in a statute, avoiding readings that make some words unnecessary or redundant. It is a guideline, not an absolute rule, and sometimes Congress does use redundant language.
Suspect Class
A group defined by characteristics like race or national origin that has historically faced discrimination, lacks political power, and possesses immutable traits. Laws targeting suspect classes receive the highest level of judicial scrutiny. Quasi-suspect classes like sex receive intermediate scrutiny.
Suspensory removal
The president's claimed power to remove an official on an interim basis while the legality of the removal is being determined, with the official staying out of office during litigation rather than remaining in place.
Take Care Clause
Article II, Section 3 of the Constitution, requiring the President to 'take Care that the Laws be faithfully executed.' Both sides cited it — petitioners as reinforcing presidential removal power, respondents as requiring adequate presidential supervision without mandating at-will removal.
Takings Clause
The part of the Fifth Amendment to the U.S. Constitution that says the government cannot take private property for public use without paying the owner fair compensation. It protects individuals from having their property seized or destroyed by the government without being paid for it.
Tax Foreclosure
A legal process by which a government seizes and sells a person's property when the owner fails to pay property taxes. The sale proceeds are used to satisfy the unpaid tax debt, and any leftover money is the 'surplus.'
Testimonial management
The practice of a lawyer coaching, strategizing about, or directing a witness's testimony—including advising on specific questions and answers, word choices, and manner of delivery. Texas argued this narrow category of conduct is what the trial court prohibited.
Title III of the Helms-Burton Act
A provision of the Cuban Liberty and Democratic Solidarity Act of 1996 that creates a private right of action in U.S. federal courts, allowing U.S. nationals whose property was confiscated by the Cuban government to sue anyone who traffics in that property. Presidents suspended this right from 1996 until 2019.
Totality of the Circumstances
A legal approach requiring courts to consider all relevant facts and context together rather than applying rigid rules or checklists. In this case, it means evaluating everything the officers knew — the girlfriend's call, their observations at the scene, and their prior experience with Case — as a whole to determine whether entry was justified.
Trafficking (under Helms-Burton Act)
A statutory term meaning to sell, transfer, distribute, dispense, or otherwise use or benefit from property that was confiscated by the Cuban government. The definition excludes activities undertaken with the authorization of the former property owner.
Trafficking (under the Helms-Burton Act)
Under the LIBERTAD Act, knowingly and intentionally using, benefiting from, or engaging in transactions involving property that was confiscated by the Cuban government from U.S. nationals.
TWEA (Trading With the Enemy Act)
A 1917 wartime statute that gave the President broad powers to regulate economic transactions with enemy nations during wartime. IEEPA was enacted in 1977 as its peacetime successor, using similar language but with different triggering conditions and oversight procedures.
Ultra Vires
Latin term meaning 'beyond the powers.' Describes government action that exceeds the legal authority granted to an agency or official. Courts will strike down ultra vires agency actions as unlawful, even if the underlying policy goal might be reasonable.
Ultra vires review
A very narrow form of judicial review in equity that allows courts to set aside government action that exceeds the agency's legal authority. In the federal subpoena context, it is the rare exception permitting early challenge to a subpoena before the normal enforcement process concludes.
Unconstitutional conditions doctrine
A constitutional principle that the government cannot condition a benefit on the surrender of a constitutional right. Justice Gorsuch raised this doctrine as potentially relevant if a court order prevented a lawyer from advising about perjury consequences or plea options.
Under-inclusiveness
A constitutional flaw where a law fails to address the problem it claims to solve by targeting only some sources of a harm while leaving equally problematic sources unregulated, undermining the claim that the law truly serves its stated interest.
Unfunded Vested Benefits (UVBs)
The difference between the present value of all pension benefits that participants have earned and cannot lose (non-forfeitable benefits) and the current value of the plan's assets. When UVBs are positive, the plan doesn't have enough money to cover all promised benefits, and this shortfall forms the basis for withdrawal liability.
Uniquely federal interest preemption
A judicial doctrine holding that in areas committed exclusively to the federal government by the Constitution, federal courts may develop common law rules that displace state law — even without an act of Congress. It applies in domains where state regulation would be fundamentally incompatible with federal authority.
UOCAVA (Uniformed and Overseas Citizens Absentee Voting Act)
A federal law passed in 1986 that requires states to allow members of the military, their families, and Americans living abroad to register and vote absentee in federal elections. It sets certain minimum standards to protect these voters' access to the ballot.
Usufruct
A legal right to use and derive profit or benefit from property that belongs to another person, as long as the property is not damaged or altered. In Cuban law, it functions similarly to a leasehold, granting the holder rights to all uses and all fruits (profits) of the property for a specified period.
Vacatur
A court order that sets aside or nullifies a previous judgment, effectively erasing it as if it never happened. When an appellate court vacates a lower court judgment, the case typically must be retried or reconsidered.
Vertical integration
A business structure where a single company controls multiple stages of production. In the oil industry, a vertically integrated company both produces crude oil from the ground and refines it into finished products, rather than buying crude on the open market.
Vesting Clause
Article II, Section 1 of the Constitution, which states 'The executive Power shall be vested in a President of the United States.' Petitioners argue this grants the President complete control over all executive functions, including an unrestricted removal power.
Vicarious liability
A form of secondary liability where a person is held responsible for another's wrongful conduct because they had the right and ability to supervise the wrongdoer and had a direct financial interest in the wrongful activity. Unlike contributory liability, it does not require knowledge of specific infringement.
Victim and Witness Protection Act (VWPA)
A 1982 federal statute that was the predecessor to the MVRA. Under the VWPA, courts had discretion to order restitution and could calibrate the amount based on the defendant's culpability, circumstances, and dependents — features more typical of criminal sentencing.
Viewpoint discrimination
A form of speech restriction where the government treats speech differently based on the particular opinion or perspective being expressed, rather than just the subject matter. It is considered the most egregious form of content discrimination and is almost always unconstitutional.
Void ab initio
A Latin phrase meaning 'void from the beginning.' A judgment that is void ab initio is treated as though it never existed because it was entered without proper authority — for example, when a court lacked jurisdiction over the defendant. Unlike a merely erroneous judgment, a void judgment has no legal force at any point.
Void vs. unenforceable
A 'void' contract is treated as if it never existed and has no legal effect. An 'unenforceable' contract may have been validly formed but cannot be enforced by a court. The distinction matters because voidness traditionally carries 'customary incidents' including the right to go to court for rescission, while unenforceability is typically raised as a defense.
Vote Dilution
The practice of drawing electoral district lines in a way that minimizes or cancels out the voting strength of a particular racial or ethnic group, such as by splitting a cohesive community across multiple districts (cracking) or concentrating them into fewer districts than warranted (packing).
Warrant
A court order authorizing law enforcement to conduct a search or seizure, issued by a judge based on probable cause and supported by oath or affirmation. A warrant must describe with particularity the place to be searched and the things to be seized. Warrants are generally required before police can conduct searches under the Fourth Amendment.
Warrantless search
A search or seizure conducted by law enforcement without a warrant. Warrantless searches are presumptively unreasonable under the Fourth Amendment unless they fall within a recognized exception, such as consent, exigent circumstances, or searches incident to lawful arrest. The government bears the burden of proving that a warrantless search fits within an exception.
Weapon Parts Kit
A commercially sold, curated collection of components designed and marketed specifically for assembly into a functional firearm. Unlike random spare parts, a weapon parts kit typically includes all components needed to build a complete gun along with instructions, jigs, or templates, and is sold with the clear intent that buyers will assemble it into a working weapon.
Well-pleaded complaint rule
The principle that federal jurisdiction in removal cases is generally determined solely by looking at the plaintiff's complaint, not at defenses the defendant might raise. The Federal Officer Removal Act is an exception to this rule, allowing removal based on the defendant's federal defense.
Willful blindness
A legal doctrine holding that deliberately avoiding knowledge of facts that would reveal illegal activity is treated the same as actually knowing about the illegality. A person cannot escape liability by intentionally closing their eyes to obvious wrongdoing.
Willfulness
A heightened criminal intent standard requiring the government to prove not only that a defendant committed an act, but that they knew the act was unlawful. Good-faith actors who genuinely believe their conduct is legal are protected from conviction even if they technically violated the law.
Withdrawal Liability
The amount of money an employer owes to a multiemployer pension plan when it stops participating in (withdraws from) the plan. It represents the employer's proportionate share of the plan's unfunded pension obligations, designed to prevent remaining employers from bearing the full cost of the departing employer's promised benefits.
Withdrawal of Plea
The act of taking back a guilty plea before or after sentencing. Courts may allow a defendant to withdraw a plea under certain conditions, but the question in Hunter's case is whether the government — not the defendant — can force the invalidation of a plea it agreed to.
Writ of Certiorari
An order issued by an appellate court (in this case, the Supreme Court) directing a lower court to send a case for review. The Supreme Court grants certiorari only when it believes a case involves important legal questions that warrant its review, typically accepting fewer than 100 cases out of over 7,000 petitions annually.
Yearsley Doctrine
A legal protection for government contractors derived from the 1940 Supreme Court case Yearsley v. W.A. Ross Construction Co. It shields contractors from liability when two conditions are met: the contractor's work was within Congress's constitutional authority, and the contractor complied with all federal directions. Whether this is an 'immunity from suit' or a 'defense to liability' is the central dispute in this case.
Younger abstention
A judicial doctrine holding that federal courts should generally refrain from interfering with ongoing state court proceedings, particularly criminal cases. If a party is already litigating in state court, the federal court will typically decline to hear the same issues.
Youngstown Zones
A framework from Justice Jackson's concurrence in Youngstown Sheet & Tube v. Sawyer for analyzing presidential power. Zone 1: President acts with congressional authorization (maximum power). Zone 2: President acts without congressional guidance (twilight zone). Zone 3: President acts contrary to Congress's will (lowest ebb of power).
