Brown v. United States (Criminal)

 These cases concern the application of the Armed Career Criminal Act to state drug convictions that occurred before recent technical amendments to the federal drug schedules. ACCA imposes a 15-year mandatory minimum sentence on defendants who are convicted for the illegal possession of a firearm and who have a criminal history thought to demonstrate a propensity for violence. As relevant here, a defendant with “three previous convictions” for “a serious drug offense” qualifies for ACCA’s enhanced sentencing. 18 U. S. C. §924(e)(1). For a state crime to qualify as a “serious drug offense,” it must carry a maximum sentence of at least 10 years’ imprisonment, and it must “involv[e] . . . a controlled substance . . . as defined in section 102 of the Controlled Substances Act.” §§924(e)(1), (2)(A)(ii). Under the categorical approach, a state drug offense counts as an ACCA predicate only if the State’s definition of the drug in question “matche[s]” the definition under federal law. Shular v. United States, 589 U. S. 154, 158. The question presented is whether a state crime constitutes a “serious drug offense” if it involved a drug that was on the federal schedules when the defendant possessed or trafficked in it but was later removed. Petitioners Justin Rashaad Brown and Eugene Jackson were separately convicted of the federal crime of possession of a firearm by a convicted felon in violation of §922(g)(1). In both cases, an ACCA enhancement was recommended based on prior state felony drug convictions. And both defendants argued that their prior convictions did not qualify as “serious drug offense[ s].” 

 Held: A state drug conviction counts as an ACCA predicate if it involved a drug on the federal schedules at the time of that offense. Pp. 4– 19.
