SCOTUS rules unanimously in favor of defendant in latest Armed Career Criminal Act ruling

The US Supreme Court handed down one opinion this morning, and it is a win for a federal criminal defendant in US v. Wooden, No. 20-5279 (S. Ct. March 7, 2022) (available here).  Here is how Justice Kagan’s opinion for the Court gets started:

In the course of one evening, William Dale Wooden burglarized ten units in a single storage facility. He later pleaded guilty, for that night’s work, to ten counts of burglary — one for each storage unit he had entered. Some two decades later, the courts below concluded that those convictions were enough to subject Wooden to enhanced criminal penalties under the Armed Career Criminal Act (ACCA).  That statute mandates a 15-year minimum sentence for unlawful gun possession when the offender has three or more prior convictions for violent felonies like burglary “committed on occasions different from one another.” 18 U.S.C. §924(e)(1).  The question presented is whether Wooden’s prior convictions were for offenses occurring on different occasions, as the lower courts held, because the burglary of each unit happened at a distinct point in time, rather than simultaneously.  The answer is no.  Convictions arising from a single criminal episode, in the way Wooden’s did, can count only once under ACCA.

Interestingly, this ruling also generated four distinct concurrences (some quite short, some longer). Because I need to be off-line most of the rest of today, I will not have a chance to comment on these opinions right away. But I hope commenters might help me try to map out how many hundreds (thousands?) of cases this ruling could impact.
