Brady v. Maryland

No. 490
Argued March 18-19, 1963
Decided May 13, 1963
373 U.S. 83

Following Brady, the prosecutor must disclose evidence or information that would prove the innocence of the defendant or would enable the defense to more effectively impeach the credibility of government witnesses. Evidence that would serve to reduce the defendant's sentence must also be disclosed by the prosecution. In practice this doctrine has often proved difficult to enforce. Some states have established their own laws to try to strengthen enforcement against prosecutorial misconduct in this area.
