Williams v. Taylor
The Court ruled that a federal habeas law barring evidentiary hearings for prisoners who "failed to develop" their claims in state court only applies when the prisoner was actually at fault - not simply whenever no state-court hearing happened.
Applying that standard, the Court found the inmate had been diligent enough to get a hearing on his juror-bias and prosecutorial-misconduct claims, but not diligent enough on a related claim about a withheld psychiatric report, so the case was sent back for further proceedings on the surviving claims.
“Diligence for purposes of the opening clause depends upon whether the prisoner made a reasonable attempt, in light of the information available at the time, to investigate and pursue claims in state court”
The Court's core test for when a prisoner is barred from a federal evidentiary hearing.
How it got here: A federal district court granted a hearing on some claims; the Fourth Circuit ruled a 1996 federal habeas law barred it; the inmate asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Michael Wayne Williams was sentenced to death for murdering a couple, the Kellers, during a robbery. After his convictions were upheld and his first state habeas petition denied, he filed a federal habeas petition raising claims that emerged only later: a hidden psychiatric report about his accomplice, and evidence that a juror and a prosecutor concealed a family and legal relationship discovered during jury selection.
The question before the Court
Could a death-row inmate get a federal court hearing on claims he never developed in state court, even though a 1996 federal law limits such hearings?
The Court's answer
Partly — the Court ruled that the federal law limiting evidentiary hearings for state prisoners only blocks a hearing when the prisoner himself was at fault for not developing the facts in state court, not whenever a state-court hearing simply never happened. A prisoner who diligently tried to uncover hidden facts but failed through no fault of his own can still get a federal hearing.
Applying that rule here, the Court found the inmate's lawyer had enough clues to investigate a hidden psychiatric report but did not follow up, so that claim stays barred. But nothing in the trial record should have alerted a diligent lawyer to a juror's concealed prior marriage and legal ties to a prosecutor, so the inmate can pursue a hearing on his juror-bias and prosecutorial-misconduct claims.

Why it matters
The ruling shapes how easily death-row and other state prisoners can get federal evidentiary hearings when new facts about their trials surface after state proceedings end. Prisoners whose lawyers made genuine, diligent efforts to uncover hidden facts - even if they came up empty because of a hidden report or a lying juror - keep access to a federal hearing, while less diligent prisoners face a much higher bar.
What changes now
The case goes back to the lower federal courts. The inmate remains barred from a hearing on the psychiatric-report claim because he could not show diligence, but he can now pursue an evidentiary hearing on his juror-bias and prosecutorial-misconduct claims. The courts below will still need to decide what standard of harm the inmate must show to actually win relief on those claims.
What this does not decide
The Court did not decide whether the inmate will ultimately win his juror-bias or prosecutorial-misconduct claims - only that he is entitled to try to prove them at a hearing. It also did not decide his claim about an undisclosed plea deal with his accomplice, which the lower court had already rejected on other grounds.
How the Court got there
The legal reasoning, step by step
- The Court focused on the opening clause of the federal habeas statute, which bars an evidentiary hearing when a prisoner "has failed to develop the factual basis of a claim in State court proceedings." The question was whether "failed" means simply that no hearing happened, or that the prisoner was somehow at fault.
- Looking at the ordinary meaning of "fail" and comparing it to a pre-existing Supreme Court case, Keeney v. Tamayo-Reyes, which required prisoners to show cause and prejudice for not developing facts in state court, the Court concluded Congress meant to keep that same fault-based idea when it wrote the new law.
- The Court held that a prisoner is barred from a hearing under this opening clause only if he or his lawyer lacked diligence - meaning they failed to make a reasonable, good-faith effort to investigate and present the claim in state court given the information available at the time.
- Applying this diligence test to the psychiatric-report claim, the Court found the inmate's state lawyer had specific hints of the report's existence in a hearing transcript but did not follow up seriously, so the claim was barred from a hearing.
- Applying the same test to the juror-bias and prosecutorial-misconduct claims, the Court found nothing in the trial record that should have tipped off a diligent lawyer to the juror's hidden prior marriage and legal relationship with a prosecutor, so the inmate had not failed to develop those claims and the statutory bar did not apply.
