Glossip v. Oklahoma
Case Overview
Glossip v. Oklahoma vacated Richard Glossip's murder conviction after the Court found that the state had suppressed material evidence and knowingly used false testimony in violation of Brady v. Maryland and Napue v. Illinois. The key withheld evidence concerned the psychiatric treatment and medication history of Justin Sneed, the prosecution's central witness and the actual perpetrator of the murder. The decision marked a significant application of Brady doctrine in a capital case involving state-sponsored misconduct.

Opinion of the Court
The Facts
Richard Glossip was convicted of first-degree murder for allegedly hiring Justin Sneed to kill Barry Van Treese. Sneed was the actual killer and served as the prosecution's primary witness. Post-conviction proceedings revealed that prosecutors had withheld evidence that Sneed had been diagnosed with a mental health condition and was receiving psychiatric treatment and medication during the period of the crime and trial, information that could have been used to impeach his testimony.
The Application
The prosecution's suppression of Sneed's psychiatric treatment records satisfied Brady's materiality standard because Sneed was the sole eyewitness to the critical fact (Glossip's alleged agreement to pay him to commit murder) and his credibility was the entire linchpin of the prosecution's capital case. Evidence of his mental health diagnosis and medication history would have provided powerful impeachment material that could reasonably have altered the jury's evaluation of whether this central witness was truthful about the crucial hiring arrangement. The prosecution's knowing elicitation of false testimony denying or concealing Sneed's psychiatric condition constituted a per se Napue violation requiring reversal independent of any materiality calculus. The combination of suppressed credibility evidence and knowing falsehoods, in a capital murder case resting entirely on a single informant's word, rendered the conviction constitutionally unreliable and demanded vacatur.
The Conclusion
**The Court vacated Glossip's conviction and remanded.** The withheld psychiatric evidence was material because it bore directly on the credibility of the prosecution's sole eyewitness to the alleged agreement to commit murder. Oklahoma's repeated efforts to execute Glossip despite evidence of prosecutorial misconduct made this one of the more contested capital cases of the term.

Case Analysis
Overview
Glossip v. Oklahoma vacated Richard Glossip's murder conviction after the Court found that the state had suppressed material evidence and knowingly used false testimony in violation of Brady v.

The key withheld evidence concerned the psychiatric treatment and medication history of Justin Sneed, the prosecution's central witness and the actual perpetrator of the murder.

Facts
Richard Glossip was convicted of first-degree murder for allegedly hiring Justin Sneed to kill Barry Van Treese. Sneed was the actual killer and served as the prosecution's primary witness. Post-conviction proceedings revealed that prosecutors had withheld evidence that Sneed had been diagnosed with a mental health condition and was receiving psychiatric treatment and medication during the period of the crime and trial, information that could have been used to impeach his testimony.
Issue
Whether the prosecution's suppression of Sneed's psychiatric treatment records and its knowing elicitation of false testimony about that treatment requires vacatur of Glossip's conviction under Brady v. Maryland and Napue v. Illinois.
Rule
The prosecution violated Brady by withholding material evidence of Sneed's psychiatric treatment and violated Napue by knowingly presenting false testimony. Suppressed evidence is material if there is a reasonable probability that disclosure would have produced a different result. The knowing use of false testimony is per se prejudicial.
Analysis
The prosecution's suppression of Sneed's psychiatric treatment records satisfied Brady's materiality standard because Sneed was the sole eyewitness to the critical fact, Glossip's alleged agreement to pay him to commit murder, and his credibility was the entire linchpin of the prosecution's capital case.
