Williams v. Taylor

Background

Terry Williams, a man convicted of murder and robbery in Virginia, was sentenced to death after a jury found future dangerousness. At trial his lawyers presented minimal mitigation — his mother, two neighbors, and a brief psychiatric tape — and emphasized that he turned himself in. After conviction, a state habeas judge found trial counsel ineffective at sentencing because they failed to investigate and present extensive mitigating records about Williams’ abusive childhood, low mental functioning, prison behavior, and other favorable evidence.

Reasoning

The Court addressed two questions: whether Williams’ Sixth Amendment right to effective counsel was violated under Strickland v. Washington, and whether the Virginia Supreme Court’s refusal to grant relief unreasonably applied federal law under 28 U.S.C. §2254(d)(1). The majority concluded the withheld mitigation was substantial, counsel’s investigation was unreasonable, and the omitted evidence created a reasonable probability of a different sentence. The Court held the Virginia court’s prejudice analysis was both contrary to and an unreasonable application of clearly established Supreme Court law, so federal habeas relief was appropriate.

Real world impact

The decision requires further proceedings on Williams’ sentence and reinforces that defense lawyers must investigate and present mitigating evidence in capital cases. It also clarifies that federal courts, while respectful of state decisions, must independently review whether state courts unreasonably applied Supreme Court precedent under federal habeas law. This ruling may prompt new scrutiny of counsel performance in other death-penalty cases.

Dissents or concurrances

Justices O’Connor and others agreed on the outcome but wrote separately about how to interpret AEDPA’s deference requirement. The Chief Justice would have denied relief on the facts.
