Castillo v. United States
Headline: Federal gun-law wording requiring harsher punishment for 'machineguns' is an element, not a sentencing factor, so juries must find weapon type — limiting judges’ ability to increase sentences based on their own findings.
Holding: The Court held that words identifying weapon types like "machinegun" in 18 U.S.C. §924(c)(1) are elements of a separate crime that must be alleged in the indictment and proven to a jury beyond a reasonable doubt.
- Prosecutors must allege weapon type in indictments.
- Juries, not judges alone, must find weapon-type facts beyond reasonable doubt.
- Reduces judges’ ability to impose enhanced sentences on their own findings.
Summary
Background
The defendants are members of the Branch-Davidian religious sect involved in the 1993 violent confrontation near Waco, Texas. They were indicted for crimes including conspiring to murder federal officers. The criminal statute at issue, 18 U.S.C. § 924(c)(1), punishes using or carrying a firearm in relation to a violent crime and prescribes much longer mandatory sentences if the weapon is a machinegun, destructive device, or equipped with a silencer. At trial a jury found the defendants guilty of using or carrying a firearm; at sentencing the judge found they used machineguns and imposed a 30-year term.
Reasoning
The central question was whether words identifying weapon types in the statute describe a separate crime element that a jury must decide, or merely a factor a judge can use to increase punishment. Looking to the statute’s language and structure, past practice, legislative history, and the practical risk of judge–jury conflicts, the Court concluded those weapon-type words are elements of a distinct, aggravated offense. The opinion explained that the single-sentence structure, the substantial difference in punishment, and the ordinary ease of having a jury identify a weapon all support treating the terms as elements. The Court reversed the Court of Appeals and remanded for proceedings consistent with this view.
Real world impact
Under this ruling, federal prosecutors must allege weapon type in indictments and present evidence for juries to decide whether the weapon was, for example, a machinegun. Sentencing judges may not rely alone on their own factual findings to impose the enhanced mandatory terms tied to those weapon types. The decision resolves a split among federal appeals courts about who decides these facts and changes how many gun-related federal prosecutions will proceed.
Dissents or concurrances
Justice Scalia joined most of the opinion but did not join point Four of Part II, as noted in the opinion.
