Kyles v. Whitley, 514 U.S. 419, 115 S.Ct. 1555, 131 L.Ed.2d 490, 63 USLW 4303

Facts

Curtis Lee Kyles was convicted of first-degree murder and sentenced to death after a second trial, following a hung jury in his first trial. The prosecution's case relied heavily on eyewitness testimony, but it was later revealed that the State had failed to disclose several pieces of evidence favorable to Kyles, including eyewitness statements and information from an informant. Kyles claimed that the prosecution's suppression of this evidence violated his rights under Brady v. Maryland, which requires the disclosure of exculpatory evidence.
