Whether AEDPA's deferential standard in 28 U.S.C. § 2254(d) applies when a state court summarily denies a federal claim without explaining its reasons.
Holding
Yes. A summary state-court denial is ordinarily an adjudication on the merits, and § 2254(d) applies unless the petitioner shows a more likely nonmerits explanation.
Reasoning
Section 2254(d) bars federal habeas relief on claims adjudicated on the merits in state court unless the state decision was contrary to, or an unreasonable application of, clearly established Supreme Court law, or rested on an unreasonable factual determination. The statute requires a state-court “decision” resulting from an “adjudication”; it does not require an opinion or a statement of reasons.
When a state court gives no explanation, the federal habeas petitioner still bears the burden of showing that there was no reasonable basis for the state court to deny relief. Federal courts must consider arguments or theories that supported, or could have supported, the unexplained state decision rather than treat the lack of reasoning as permission to conduct de novo review.
When a state court denies relief after a federal claim has been presented, courts presume that the denial was on the merits absent an indication to the contrary or a state-law procedural rule suggesting otherwise. Richter offered only speculation that the California Supreme Court may have acted on some other basis, so he did not overcome that presumption.
The Court also rejected the argument that applying AEDPA to summary rulings would induce state courts to avoid explaining themselves. State courts may use summary dispositions to conserve resources and focus written opinions on cases in which they are most useful.
