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.

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.
