Whether the Ninth Circuit used the proper standard for deciding whether a state court unreasonably applied clearly established federal law under AEDPA, 28 U.S.C. § 2254(d)(1).
Holding
No. A federal habeas court may not grant relief merely because it independently finds the state court’s decision erroneous or clearly erroneous; the state court’s application must be objectively unreasonable.
Reasoning
AEDPA asks whether the state decision was contrary to, or involved an unreasonable application of, clearly established Supreme Court law. It does not require federal habeas courts to conduct de novo review of the constitutional issue before applying that deferential standard.
The Ninth Circuit equated an “objectively unreasonable” application with “clear error.” That approach improperly conflated error with unreasonableness and failed to give state-court judgments the deference AEDPA demands.
Under Williams v. Taylor, a federal court cannot issue the writ simply because it believes the state court decided the federal question incorrectly. Relief is available only when the state court’s application of the governing rule was objectively unreasonable.
