Stephen L. Voisine and William E. Armstrong, Iii, Petitioners v. United States.

Summary

The Supreme Court held that misdemeanor assault convictions for reckless conduct qualify as 'misdemeanor crimes of domestic violence' under 18 U.S.C. § 922(g)(9), triggering the federal firearms ban. The Court concluded that the statutory phrase 'use of physical force' encompasses volitional acts undertaken with conscious disregard of a substantial risk of harm, not just intentional or knowing acts.
