Whether AEDPA permitted federal habeas relief from the Maryland courts' rejection of Wiggins's ineffective-assistance claim.
Holding
Yes. The Maryland Court of Appeals unreasonably applied clearly established Strickland principles and partly relied on an unreasonable factual determination.
Reasoning
Under 28 U.S.C. § 2254(d)(1), a federal court may grant habeas relief when a state court identifies the governing rule but applies it to the facts in an objectively unreasonable way. The standard is demanding: a state decision must be more than wrong; it must be objectively unreasonable. Strickland, which was clearly established when the Maryland court ruled, supplied the governing rule.
The Maryland court treated counsel's possession of the presentence report and social-services records as sufficient to support a tactical decision not to present a fuller mitigation case. But Strickland requires a court to assess whether the investigation underlying the strategy was reasonable. The state court effectively assumed that a limited investigation justified the strategy, rather than asking whether reasonable professional judgment supported stopping the investigation when counsel did.
The state court also stated that the social-services records documented sexual abuse. They did not. The State and the United States conceded that those records contained no such evidence. This clear factual error was an unreasonable determination of fact under § 2254(d)(2) and further undermined the state court's conclusion that counsel already knew enough to make an informed choice.
