Brigham City v. Stuart
Does the Fourth Amendment permit police officers to make a warrantless entry into a private home when they have an objectively reasonable basis for believing that an occupant is seriously injured or faces imminent serious physical harm?

The Supreme Court ruled unanimously, 9–0, in favor of Brigham City, reversing the Utah Supreme Court's decision. The opinion was authored by Chief Justice John G. Roberts Jr. The Court held that police officers may make a warrantless entry into a home when they have an objectively reasonable basis for believing that an occupant is seriously injured or imminently threatened with such injury. The officers' subjective motivations for entering are irrelevant to the Fourth Amendment analysis.
Chief Justice Roberts grounded the decision in a core Fourth Amendment principle: the reasonableness of a government intrusion does not depend on the actual motivations of the individual officers involved. The Court pointed to a long line of precedent establishing that the Fourth Amendment's protections are measured by an objective standard. Just as an officer's subjective intent to find drugs does not invalidate an otherwise lawful traffic stop, an officer's subjective law-enforcement purpose does not invalidate an otherwise justified emergency entry. What matters is whether the circumstances, viewed objectively, justified the action taken.
The Court then applied this objective standard to the facts. The officers had witnessed a juvenile punch an adult in the face with enough force to cause bleeding. This was an ongoing act of violence occurring right before their eyes. Any reasonable officer in that position would have believed that the injured adult needed assistance and that the violence could escalate further. Under these circumstances, the Court found that the officers had an objectively reasonable basis for believing an occupant was seriously injured or faced imminent serious injury, which justified their warrantless entry.
The Court explicitly rejected the Utah Supreme Court's approach of inquiring into whether the officers' primary motivation was to render aid or to gather evidence and make arrests. Such a subjective inquiry, the Court explained, was incompatible with the objective reasonableness framework that governs Fourth Amendment analysis. The decision established a clear, workable standard: courts evaluating emergency aid entries should look at the totality of the objective circumstances, not peer into the minds of the officers involved.
Concurring Opinions
Justice Stevens wrote a brief concurring opinion in which he emphasized that while he agreed with the Court's holding and its rejection of the subjective-motivation test, he wanted to underscore that the objective standard still requires a genuine emergency — the mere possibility of an emergency is not enough, and the police conduct must be a reasonable response to the specific emergency at hand.
Background & Facts
In the early morning hours of July 23, 2000, police officers in Brigham City, Utah responded to a call about a loud house party. When they arrived at the residence, they could hear shouting from inside. Officers walked around the side of the house and into the backyard, where they observed two juveniles drinking beer in the backyard. Through a screen door and windows, they looked into the kitchen and saw a chaotic scene: a fight had broken out between adults and a juvenile inside the home.
Specifically, the officers witnessed four adults attempting to restrain a young man. The juvenile broke free and punched one of the adults hard in the face, causing the adult to spit blood into the kitchen sink. Seeing this violent altercation unfolding in real time, one of the officers opened the screen door, announced the police presence, and stepped inside. The officers ultimately arrested several individuals, including Stuart and others, on charges including contributing to the delinquency of a minor and disorderly conduct.
The defendants moved to suppress all evidence obtained as a result of the warrantless entry, arguing it violated the Fourth Amendment. The trial court granted the motion. On appeal, the case eventually reached the Utah Supreme Court, which affirmed the suppression of evidence. Critically, the Utah Supreme Court applied a test that looked at the officers' subjective motivations for entering the home. The state court concluded that the primary reason the officers entered was not to render emergency aid but rather to make an arrest or otherwise enforce the law, and therefore the warrantless entry was unconstitutional.
The U.S. Supreme Court agreed to hear the case because the Utah Supreme Court's approach — focusing on officers' subjective motivations rather than objective circumstances — conflicted with established Fourth Amendment principles and created confusion about when police could lawfully enter a home without a warrant to assist someone in danger. The case presented an important question about the so-called 'emergency aid' exception to the warrant requirement.
The Arguments
The city argued that the officers' warrantless entry into the home was constitutionally justified because they witnessed an ongoing act of violence — a juvenile punching an adult in the face hard enough to draw blood. The test for whether such an entry is lawful should be purely objective: whether a reasonable officer would believe someone inside was injured or in imminent danger of injury.
- The officers personally witnessed a violent physical altercation through the window, giving them an objectively reasonable basis to believe someone was being seriously harmed
- Under well-established Fourth Amendment precedent, the reasonableness of a search or seizure depends on objective circumstances, not on officers' subjective motivations or states of mind
- The Utah Supreme Court's subjective-motivation test was unworkable and contrary to the practical realities of policing, as officers in emergency situations should not be second-guessed based on their internal thoughts
Stuart and the other respondents argued that the warrantless entry violated the Fourth Amendment because the officers' true purpose in entering the home was to investigate criminal activity and make arrests, not to provide emergency assistance to anyone inside.
- The officers had multiple opportunities to seek a warrant or use less intrusive means before physically entering the home
- The situation inside the house, while involving a scuffle, did not rise to the level of a genuine emergency requiring immediate entry
- The officers' subjective intent matters because the emergency aid exception should not become a pretext for law enforcement to bypass the warrant requirement
