Summary: written with AI from the case record.

What it's about
It ruled that federal courts must presume—unless rebutted—that a state court decided a federal claim’s substance when its explained decision rejected other claims without expressly addressing that claim.
Tara Williams challenged her conviction in federal court after a California court denied relief in an explained decision that did not expressly address her federal-law claim.
The dispute arose under a federal law that sets limits on federal review of state prisoners’ claims.
Question presented
Is a habeas petitioner's claim "adjudicated on the merits" if the state court denied relief in an explained decision but did not expressly acknowledge the federal-law basis for the claim?
What the Court decided
Holding
1. For purposes of §2254(d), when a state court rules against a defendant in an opinion that rejects some of the defendant’s claims but does not expressly address a federal claim, a federal habeas court must presume, subject to rebuttal, that the federal claim was adjudicated on the merits. 646 F. 3d 626, reversed and remanded.

More questions
- What did Justice Scalia disagree with?
- He argued that a state court’s accidental oversight should not by itself overcome the presumption; he would require evidence from the court’s order or the state’s usual practice showing it did not mean to decide the federal issue.
