Connick v. Thompson

Prosecutors in the Orleans Parish, La., district attorney’s office deliberately withheld exculpatory evidence from the plaintiff, a former defendant in a criminal case, in violation of Brady v. Maryland, 373 U.S. 83 (1963), and the office was found liable for failure to train its prosecutors in their Brady obligations. Brief argues that a “single violation” is sufficient to incur municipal liability (“Canton liability”) for failure to train prosecutors in their Brady disclosure obligations.
