Glossip v. Oklahoma Revisions: 2/25/25
The Supreme Court ruled that Oklahoma prosecutors violated Richard Glossip's constitutional rights by knowingly allowing their only direct witness against him to lie under oath about his mental health treatment — and ordered a new trial in a death-penalty case litigated for nearly three decades.
The decision reinforces the constitutional rule that prosecutors must correct false testimony by their own witnesses, and it hands a major victory to Glossip, who has maintained his innocence throughout his time on death row.
How it got here: The Oklahoma Court of Criminal Appeals denied Glossip's successive post-conviction petition as procedurally barred and meritless; the Supreme Court stayed his scheduled execution and agreed to hear the case.
The Case in Depth
What happened
Richard Glossip has been on Oklahoma's death row since 1998, convicted of hiring handyman Justin Sneed to beat motel owner Barry Van Treese to death in 1997. Sneed — who received a favorable plea deal in exchange for testifying — was the only witness who directly linked Glossip to the murder. During Glossip's second trial in 2004, Sneed falsely testified he had never seen a psychiatrist and had no idea why he was given lithium, when in fact he had been diagnosed with bipolar disorder and prescribed lithium by a jail psychiatrist. Oklahoma's own attorney general later concluded that the lead prosecutor had knowingly let this false testimony stand.
The question before the Court
Did Oklahoma prosecutors violate Richard Glossip's constitutional rights when they knowingly allowed their star witness to lie on the stand about his psychiatric treatment, and does that entitle Glossip to a new capital trial?
The Court's answer
Yes — the prosecution violated Glossip's constitutional rights by knowingly allowing its star witness to falsely testify that he had never seen a psychiatrist and had no idea why he was given lithium, when in fact a jail psychiatrist had diagnosed him with bipolar disorder and prescribed lithium to treat it. Under Napue v. Illinois, a 1959 precedent, prosecutors have a constitutional duty under the Due Process Clause to correct false testimony by their own witnesses — an obligation the lead prosecutor here failed.
The false testimony was legally significant because Sneed was the only witness directly connecting Glossip to the murder, making his credibility the whole case. Correcting the lie would have exposed Sneed as willing to commit perjury on the stand and would have undercut the prosecution's portrayal of Sneed as too passive to kill without Glossip's direction. With Oklahoma's own attorney general confessing the violation, and the record clearly supporting that confession, Glossip is entitled to a new trial.

Why it matters
Prosecutors nationwide are reminded they have an affirmative constitutional duty to correct false testimony by their own witnesses — even when the false statement seems minor or peripheral. Letting a witness lie about something as seemingly secondary as a prescription drug can be enough to undo a capital conviction and force a new trial decades later, at great cost to courts, victims' families, and the justice system.
What changes now
The case returns to Oklahoma courts for a new trial on the capital murder charge. The Supreme Court did not reach Glossip's separate Brady claim — that the prosecution withheld other evidence — leaving that issue potentially available on remand. Oklahoma prosecutors will face the challenge of retrying a case from 1997 with key physical evidence that was destroyed before the 2004 retrial. Justice Gorsuch took no part in the decision.
What this does not decide
The Court did not decide Glossip's Brady claim that other evidence was unlawfully withheld. The ruling also does not determine whether Glossip is actually innocent — only that constitutional errors at his second trial entitle him to a new one. The decision does not resolve what additional state-law procedural questions the Oklahoma courts may address on remand.
Concurrences and dissents
Concurrence in part — Justice Barrett
Justice Barrett agreed with the majority on jurisdiction (joining Part II) and agreed the state court had misapplied Napue, but she would not have ordered a new trial. She argued the record contained competing, plausible interpretations of the lead prosecutor's pretrial notes, and that the Supreme Court should not be acting as the initial factfinder on contested questions of fact. She would have corrected the state court's misstatement of federal law, vacated the judgment, and sent the case back to the Oklahoma Court of Criminal Appeals to make its own factual findings and decide next steps.
Dissent — Justice Thomas
Justice Thomas argued the Court lacked jurisdiction because the state court's procedural bar under Oklahoma's Post-Conviction Procedures Act was an adequate and independent state-law ground that the majority misread. On the merits, he argued Sneed's statements about his psychiatric treatment were not material because the defense had known about Sneed's mental health condition since 1997 and made a strategic choice not to use it at the second trial. He also argued the Court had no authority to order a new trial and at most should have remanded for further state-court proceedings, emphasizing that multiple unresolved state-law questions — and the victim's family's interest in being heard — required an evidentiary hearing before any relief could be granted.
How the Court got there
The legal reasoning, step by step
- The Court first had to decide whether it had power to hear the case. Oklahoma argued that the state court's procedural dismissal under the Post-Conviction Procedures Act (PCPA) — a state law limiting repeat post-conviction petitions — was an 'independent and adequate state-law ground' that cut off federal review. The Court found it was not, because the state court's decision to apply the PCPA turned on an antecedent federal-law ruling: the court refused to honor the attorney general's concession of error only after concluding — as a matter of federal constitutional law — that no Napue violation had occurred.
- Under Michigan v. Long (the 1983 rule that this Court presumes federal reliance when the state court's independent grounds are not clearly spelled out on the face of the opinion), the Court found it had jurisdiction, because the state court's procedural dismissal was intertwined with its federal-law analysis rather than standing apart from it.
- Turning to the merits, the Court applied Napue v. Illinois: a prosecution violates the Fourteenth Amendment's Due Process Clause when it knowingly allows false testimony to go uncorrected, and a new trial is required if there is any reasonable likelihood the false testimony could have affected the jury's verdict — meaning the prosecution must establish harmlessness beyond a reasonable doubt.
- The falsity element was established clearly: Sneed testified he had never seen a psychiatrist and had no idea why he was given lithium, but medical records showed he was diagnosed with bipolar disorder and prescribed lithium by Dr. Trombka, the jail psychiatrist. The lead prosecutor's own pretrial notes — referencing 'lithium' and 'Dr. Trumpet' (meaning Trombka) — showed she knew before trial that Sneed's story about getting lithium after asking for cold medicine was false.
- The false testimony was material — meaning it could reasonably have changed the outcome — for two independent reasons. First, because Sneed was the only direct evidence of Glossip's guilt, his credibility was the entire case; correcting his lie would have revealed to the jury that he was willing to commit perjury on the stand. Second, the prosecution's closing argument portrayed Sneed as harmless without Glossip's direction; proof that Sneed had a disorder that, combined with drug use, could trigger impulsive violence would have undermined that central theory.
- Because the record clearly supported the attorney general's confession of error and all parties agreed no further evidentiary hearing was needed, the Court declined to remand for additional proceedings. A new trial — the standard remedy for a Napue violation — was ordered directly.
