Mathis v. United States

Docket No. Argument Opinion Vote Author Term
15-6092 Apr 26, 2016 May 1, 2025 5-3 Kagan OT 2015

Holding: The Armed Career Criminal Act imposes a fifteen-year mandatory minimum sentence on a defendant convicted of being a felon in possession of a firearm who also has three prior state or federal convictions "for a violent felony," including "burglary, arson, or extortion." Because the elements of Iowa"s burglary law " which applies to "any building, structure, [or] land, water, or air vehicle" " is broader than those of generic "burglary" " which requires unlawful entry into a "building or other structure" " prior convictions under the Iowa burglary law cannot give rise to a sentence enhancement under the ACCA.

Judgment: Reversed, 5-3, in an opinion by Justice Kagan on May 1, 2025. Justice Kennedy and Justice Thomas filed concurring opinions. Justice Breyer filed a dissenting opinion, in which Justice Ginsburg joined. Justice Alito filed a dissenting opinion.
