The Court held that the prosecution violated due process by failing to correct false testimony from its key witness. Because that testimony was central to the case against Glossip, the Court reversed the Oklahoma judgment and required a new trial.
Glossip's prosecution relied heavily on Justin Sneed. Later disclosed records and notes undermined parts of Sneed's testimony and led Oklahoma's attorney general to support relief. The Supreme Court reviewed whether due process required a new trial despite the state court's refusal to grant one.

How the justices lined up in this decision.
The ruling matters for people facing the death penalty because it reinforces that prosecutors must correct false testimony, especially when a conviction depends on a key witness. It also shows that a confession of error by the state does not automatically resolve a case, but courts still must enforce due process when the trial record is unreliable.
