Brady material is evidence that is potentially helpful to a defendant in a criminal case. It is named after the U.S. Supreme Court decision of Brady v. Maryland, 373 U.S. 83 (1963), which requires a prosecutor to disclose this information to a defendant during a criminal prosecution.
Brady material includes:
- exculpatory evidence which tends to exonerate a defendant of the charges;
- mitigation evidence which tends to weaken the severity of the alleged wrongdoing; and
- impeachment evidence which tends to reduce the credibility of a witness, such as plea bargains by the prosecutor with any witness.
