What it's about
The decision left Jamar Quarles’s Michigan conviction eligible to support the ACCA’s longer sentence for certain repeat firearm offenders.
The case concerns how federal courts compare state crimes with the federal definition of burglary in the Armed Career Criminal Act.
Question presented
Whether (as two circuits hold) Taylor's definition of generic burglary requires proof that intent to commit a crime was present at the time of unlawful entry or first unlawful remaining, or whether (as the court below and three other circuits hold) it is enough that the defendant formed the intent to commit a crime at any time while "remaining in" the building or structure.
What the Court decided
Holding
1. Generic remaining-in burglary occurs under §924(e) when the defendant forms the intent to commit a crime at any time while unlawfully remaining in a building or structure. In ordinary usage, “remaining-in” refers to a continuous activity, and this Court has followed that ordinary meaning in analogous legal contexts, see, e.g. , United States v. Cores , 356 U. S. 405, 408. 2. For the Court’s purposes here, the Michigan home-invasion statute substantially corresponds to or is narrower than generic burglary. The conclusion that generic remaining-in burglary occurs when the defendant forms the intent to commit a crime at any time while unlawfully remaining in a building or structure resolves this case. When deciding whether a state law is broader than generic burglary, the state law’s “exact definition or label” does not control. Taylor, 495 U. S., at 599. So long as the state law in question “substantially corresponds” to (or is narrower than) generic burglary, the conviction qualifies. Ibid . 850 F. 3d 836, affirmed.

Why it matters
It also settles the timing question for “remaining-in” burglary under that law.
