Burrage v. United States
The Court ruled that a drug dealer can only face a 20-year mandatory minimum sentence for a customer's overdose death if the drug he sold was an actual but-for cause of death — meaning the person would not have died without it.
Because the victim in this case had taken several drugs and experts could not say he would have lived without the heroin, the enhanced sentence could not stand, and the case goes back for further proceedings.
“Where there is no textual or contextual indication to the contrary, courts regularly read phrases like “results from” to require but-for causality.”
The Court's core reasoning for why the statute requires but-for causation.
How it got here: A federal jury convicted Burrage and the trial court imposed the 20-year mandatory minimum; the Eighth Circuit affirmed, and the Supreme Court agreed to review the causation question.
The Case in Depth
What happened
Joshua Banka, a long-time drug user, died after a binge that included oxycodone, marijuana, and heroin he bought from Marcus Burrage. Medical experts testified heroin was a "contributing" factor to Banka's death but could not say he would have died without it, since multiple other drugs were also in his system. Burrage was charged with distributing heroin that "resulted" in Banka's death, triggering an enhanced mandatory minimum sentence.
The question before the Court
If a man died after using heroin along with several other drugs, could the seller be hit with a 20-year mandatory minimum just because the heroin contributed to his death?
Why it matters
The ruling makes it harder for prosecutors to secure lengthy mandatory-minimum sentences in overdose cases involving multiple drugs, a common real-world scenario. Dealers can still be convicted and sentenced under the default drug-distribution penalties, but the harsher 20-year floor now requires proof the specific drug they supplied was truly decisive in causing death, not just one contributing factor among several.
What changes now
The case returns to the lower courts for further proceedings consistent with the Court's but-for causation standard. Burrage remains guilty of the underlying heroin-distribution offense and faces the standard sentencing range for that crime, but the enhanced 20-year mandatory minimum tied to Banka's death can no longer apply absent proof that the heroin was a but-for cause of death.
What this does not decide
The Court did not decide how causation works when multiple drugs or actions are each independently sufficient on their own to cause death — a special rule some courts use for such 'multiple sufficient causes' scenarios. It resolved only the situation where the defendant's drug was not independently enough to cause death by itself.
Concurrences and dissents
Concurrence in part — Justice Alito
Justice Alito joined the entire opinion except Part III-B, the section addressing the government's policy arguments about the practical difficulties of requiring but-for causation in overdose cases. He agreed with the core but-for causation holding but did not join the Court's extended discussion of why a looser standard would create its own uncertainty.
Concurrence — Justice Ginsburg
Justice Ginsburg, joined by Justice Sotomayor, agreed with the outcome but not the majority's broader reasoning about the ordinary meaning of causal phrases like 'because of.' She reiterated her view from a prior dissent that such phrases need not always mean sole causation, but agreed that when a criminal statute is ambiguous, courts should not choose the interpretation that disfavors the defendant, which was enough to support the judgment here.
How the Court got there
The legal reasoning, step by step
- The Court explained that criminal causation traditionally has two parts: actual cause (did the conduct actually bring about the result) and legal or 'proximate' cause (is the conduct closely enough connected to be fairly blamed). The Court focused only on actual cause here.
- Because the mandatory-minimum provision increases both the minimum and maximum sentence a defendant faces, it counts as an element of the crime that a jury must find beyond a reasonable doubt, not just a sentencing factor a judge can find on the side.
- The Court read the statutory phrase 'results from' according to its ordinary meaning, concluding that it requires but-for causation — proof that the death would not have happened without the defendant's drug, much like similar phrases such as 'because of' or 'by reason of' have been read in other federal statutes.
- The Court declined to adopt a looser 'contributing factor' or 'substantial factor' standard, noting that such tests are vague, inconsistently applied by courts, and cannot be reconciled with the certainty required in criminal law, especially under the rule of lenity that favors defendants when a criminal statute is ambiguous.
- The Court left open a narrow exception for cases where multiple independently sufficient causes act together to cause death, but found it unnecessary to resolve that scenario here because no evidence showed heroin alone would have killed Banka.
- Applying but-for causation to the facts, the Court concluded that because experts could not say Banka would have died without the heroin, the enhanced sentence could not be sustained on this record.
