- Brady material
"Brady" material consists of exculpatory or impeaching information that is material to the guilt or innocence or to the punishment of a defendant. The term comes from the
U.S. Supreme Courtcase, " Brady v. Maryland", [373 U.S. 83 (1963)] in which the Supreme Court ruled that suppression by the prosecution of evidence favorable to a defendant who has requested it violates due process. Following "Brady", the prosecutor must disclose evidence or information that would prove the innocence of the defendant. Evidence that would serve to reduce the defendant's sentence must also be disclosed by the prosecution.
* The prosecutor must disclose an agreement not to prosecute a witness in exchange for the witness's testimony. [Giglio v. U.S., 405 U.S. 150 (1972).]
* The prosecutor must disclose leniency (or preferential treatment) agreements made with witnesses in exchange for testimony. [U.S. v. Sudikoff, 36 F.Supp. 2d 1196 (C.D. Cal. 1999); State v. Lindsey, 621 So. 2d 618 (La. Ct. App. 1993).]
* The prosecutor must disclose exculpatory evidence known only to the police. This imposes a duty on the prosecutor to review the police's investigatory files and disclose anything that tends to prove the innocence of the defendant. [Kyles v. Whitley, 514 U.S. 419 (1995).]
* The prosecutor must disclose arrest photographs of the defendant when those photos do not match the victim's description. [Commonwealth v. Tucceri, 412 Mass. 401 (1992).]
