Kimbrough v. United States
May a federal district court judge, when sentencing a defendant, consider the disparity between the harsher crack cocaine sentencing guidelines and the more lenient powder cocaine guidelines as a reason to impose a sentence below the recommended guideline range?
The Decision
7-2 decision · Opinion by Ruth Bader Ginsburg · 2007
Majority Opinion— Ruth Bader Ginsburgconcurring ↓dissent ↓
In a 7–2 decision authored by Justice Ruth Bader Ginsburg, the Supreme Court reversed the Fourth Circuit and held that district courts may consider the crack/powder cocaine sentencing disparity when exercising their discretion to impose a sentence outside the guideline range. The Court upheld Kimbrough's 180-month sentence as reasonable.
The majority's reasoning began with the framework established in the Court's earlier decisions making the Sentencing Guidelines advisory. Under federal sentencing law — specifically 18 U.S.C. § 3553(a) — judges must consider the guideline range but also a host of other factors, including the nature and circumstances of the offense, the need for just punishment, deterrence, and the need to avoid unwarranted sentencing disparities. The Court emphasized that this statute gives sentencing judges considerable latitude and does not require them to treat the guidelines as effectively mandatory simply because they reflect a policy choice Congress made.
Critically, the Court noted that the crack/powder guidelines were not the product of the Sentencing Commission's usual empirical, data-driven process. Instead, they were driven by mandatory minimum sentences that Congress enacted in 1986 in a climate of public alarm about crack cocaine. The Sentencing Commission had never endorsed the 100-to-1 ratio on its own merits; in fact, it had sent multiple reports to Congress explaining that the ratio was unjustified and recommending a significant reduction. The Court reasoned that because the crack guidelines did not reflect the Commission's characteristic institutional expertise, district courts were not acting unreasonably when they concluded that the resulting sentencing range was greater than necessary to serve the purposes of sentencing.
The Court was careful to note that it was not saying every below-guideline crack sentence would be reasonable, nor was it mandating any particular ratio. It simply held that a judge who decides that the crack guidelines yield an excessive sentence in a particular case, and who carefully considers all the § 3553(a) factors, is exercising the kind of reasoned discretion that the advisory guideline system contemplates. The Court also stressed that Congress knows how to constrain judicial sentencing discretion when it wants to — through mandatory minimums and other express directives — and it had not done so with respect to guideline departures based on the crack/powder disparity.
Concurring Opinions
Justice Scalia wrote a concurrence emphasizing that the advisory guidelines system means district courts cannot be bound by any guideline that does not reflect the jury's findings or the defendant's admissions, and he expressed skepticism toward any appellate standard of review that would effectively make certain guidelines mandatory in practice. Justice Souter also wrote a brief concurrence.
Dissenting Opinions
Clarence Thomas
Justice Thomas dissented because he continued to disagree with the foundational premise of the majority's reasoning — the earlier decision in United States v. Booker that made the Sentencing Guidelines advisory. In his view, the Guidelines should remain mandatory as Congress intended, and the entire post-Booker framework of advisory guidelines and reasonableness review was illegitimate.
- The Booker decision improperly rewrote the federal sentencing statute by converting mandatory guidelines into advisory ones, and subsequent decisions like Kimbrough compounded that error.
- Under the original statutory scheme, Congress clearly intended the Guidelines to be binding, and allowing judges to reject guideline ranges based on policy disagreements defeats Congress's purpose of achieving sentencing uniformity.
Samuel Alito
Justice Alito argued that even under the advisory guidelines framework, district courts should not be permitted to substitute their own policy judgments for those of Congress regarding the relative seriousness of crack and powder cocaine offenses. He warned that the majority's ruling would produce significant sentencing disparities and effectively allow individual judges to override a deliberate legislative choice.
- The 100-to-1 ratio reflected a considered policy judgment by Congress, and the democratic process — not individual judicial preferences — is the proper mechanism for changing it.
- Allowing district courts to reject guidelines based on policy disagreements, rather than case-specific circumstances, threatens the uniformity that the Sentencing Reform Act was designed to achieve.
- The majority's distinction between guidelines that reflect the Sentencing Commission's empirical expertise and those driven by congressional mandates is unworkable and invites judges to selectively disregard guidelines they personally disfavor.
Background & Facts
Derrick Kimbrough was a veteran of the first Gulf War who, after returning home, became involved in the drug trade in Norfolk, Virginia. In 2005, he was caught with 56 grams of crack cocaine, 92.1 grams of powder cocaine, and a firearm. He pleaded guilty to four federal charges: conspiracy to distribute crack and powder cocaine, possession with intent to distribute more than 50 grams of crack cocaine, possession with intent to distribute powder cocaine, and possession of a firearm in furtherance of a drug trafficking crime.
At the heart of Kimbrough's case was a long-controversial feature of federal drug sentencing law. Under the Anti-Drug Abuse Act of 1986 and the resulting federal Sentencing Guidelines, crack cocaine offenses were punished roughly 100 times more severely than equivalent powder cocaine offenses. This meant that possessing just 5 grams of crack triggered the same mandatory minimum sentence as possessing 500 grams of powder cocaine — even though crack and powder cocaine are pharmacologically the same substance. This 100-to-1 ratio had been widely criticized by judges, scholars, and the U.S. Sentencing Commission itself as producing unjust outcomes, and it had a stark racial dimension: the vast majority of crack defendants were Black, while powder cocaine defendants were more racially diverse.
Under the Sentencing Guidelines as they applied to Kimbrough, his recommended prison term was 228 to 270 months (19 to 22.5 years). The sentencing judge, however, concluded that this range was excessive and that the crack/powder disparity drove an unreasonable result in Kimbrough's case. The judge sentenced him instead to 180 months (15 years), still a significant prison term but well below the guideline range. The judge explicitly noted that if Kimbrough's crack had been treated like powder cocaine, his guideline range would have been much lower.
The U.S. Court of Appeals for the Fourth Circuit reversed the sentence. It held that after the Supreme Court's landmark 2005 decision making the federal Sentencing Guidelines advisory rather than mandatory, a district court still could not impose a sentence below the guideline range based on a disagreement with the crack/powder disparity. In the Fourth Circuit's view, such a departure was effectively per se unreasonable. Other federal appeals courts had split on this question, and the Supreme Court agreed to hear the case to resolve the disagreement.
The Arguments
Kimbrough argued that after the Supreme Court made the federal Sentencing Guidelines advisory, district judges have broad discretion to consider all relevant factors when crafting an individualized sentence — including the widely acknowledged unfairness of the 100-to-1 crack-to-powder cocaine sentencing ratio. His below-guideline sentence was reasonable and should be upheld.
- The Supreme Court's prior decision in United States v. Booker made the Sentencing Guidelines advisory, meaning judges are no longer bound to follow them mechanically.
- Federal sentencing law (18 U.S.C. § 3553(a)) directs judges to consider a wide range of factors in crafting a just sentence, and nothing in that statute forbids considering the crack/powder disparity.
- The U.S. Sentencing Commission itself had repeatedly told Congress that the 100-to-1 ratio was unjustified and produced sentences that were excessively harsh for crack offenders compared to powder cocaine offenders.
The government argued that while the Sentencing Guidelines are advisory, a district court cannot use its disagreement with a specific policy choice embedded in the guidelines — particularly one that reflects Congress's own judgment about the relative seriousness of crack versus powder cocaine — as a basis for imposing a lower sentence. Allowing judges to override this legislative policy choice would undermine uniformity in sentencing.
- Congress itself enacted the statutory framework that produced the 100-to-1 ratio, and judicial second-guessing of that legislative judgment is inappropriate.
- Permitting district courts to deviate from the guidelines based on policy disagreements would create unwarranted sentencing disparities across the country.
- The proper remedy for any perceived unfairness in the crack/powder ratio is legislative reform, not ad hoc judicial adjustments at sentencing.
