Connick v. Thompson

OPINION OF THE COURT [563 U.S. 54] Justice Thomas delivered the opinion of the Court.

The Orleans Parish District Attorney’s Office now concedes that, in prosecuting respondent John Thompson for attempted armed robbery, prosecutors failed to disclose evidence that should have been turned over to the defense under Brady v. Maryland, 373 U.S. 83, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963). Thompson was convicted. Because of that conviction Thompson elected not to testify defense in his later trial for murder, and he was again convicted. Thompson spent 18 years in prison, including 14 years on death row. One month before Thompson’s scheduled execution, his investigator discovered the undisclosed evidence from his armed robbery trial. The reviewing court determined that the evidence was exculpatory, and both of Thompson’s convictions were vacated.

After his release from prison, Thompson sued petitioner Harry Con-nick, in his official capacity as the Orleans Parish district attorney, for damages under Rev. Stat. § 1979, 42 U.S.C. § 1983. Thompson alleged that Connick had failed to train his prosecutors adequately about their duty to produce exculpatory evidence and that the lack of training had caused the nondisclosure in Thompson’s robbery case. The jury awarded Thompson $14 million, and the Court of Appeals for the Fifth Circuit affirmed by an evenly divided en banc court. We granted certiorari to decide whether a district attorney’s office may be held liable under § 1983 for failure to train based on a single Brady violation. We hold that it cannot.
