What it's about

The Court held that the Ninth Circuit improperly reviewed the claim anew instead of giving the required deference to the state court’s decision under federal habeas law.

The case concerns how much deference federal courts must give state-court decisions under the federal habeas law.

Question presented

Whether the court of appeals violated the deferential review requirements of 28 U.S.C. § 2254(d) by setting aside a state conviction based on its de novo analysis of an ineffective-assistance claim, without fulfilling its obligation to consider whether fair-minded jurists could agree with the state court’s contrary conclusion?
