Whether AEDPA permitted habeas relief based on the Ninth Circuit’s view that counsel was ineffective because there was "nothing to lose" by pursuing the insanity defense.
Holding
No. The California court’s rejection of the ineffective-assistance claim was not contrary to, or an unreasonable application of, clearly established Supreme Court law under 28 U.S.C. § 2254(d)(1).
Reasoning
AEDPA permits federal habeas relief only when a state court’s merits decision is contrary to, or unreasonably applies, clearly established federal law as determined by the Supreme Court. The relevant clearly established law here was Strickland v. Washington’s general two-part standard for ineffective assistance: deficient performance and resulting prejudice.
The Ninth Circuit effectively imposed a separate "nothing to lose" rule: counsel was deficient for abandoning a defense unless withdrawal produced an affirmative tactical advantage. But the Supreme Court had never adopted such a rule. A federal habeas court cannot declare a state decision unreasonable for failing to follow a legal principle that this Court has not clearly established.
Strickland is a general standard, so state courts retain substantial latitude in applying it to particular facts. Review under AEDPA is therefore doubly deferential: courts defer first to counsel’s professional judgment and then to the state court’s reasonable application of Strickland. Under that demanding standard, the state court could reasonably conclude that counsel was not ineffective.
