The Brady Rule

The Brady Doctrine, stemming from the landmark case Brady v. Maryland, 373 U.S. 83 (1963), is a critical principle in U.S. criminal law. It mandates that the prosecution must disclose to the defense any exculpatory evidence (evidence favorable to the defendant) that is material to either guilt or punishment. Key Elements of the Brady Doctrine:

The prosecution is required to disclose to the defense any evidence that is favorable to the accused and material to guilt or punishment. Includes any information that might exonerate the defendant, reduce their culpability, or lead to a lesser sentence.

For evidence to be considered "material," there must be a reasonable probability that, had the evidence been disclosed, the result of the proceeding would have been different. This standard helps determine whether the non-disclosure of evidence can be considered a violation of due process rights.

The prosecution's duty to disclose applies both before the trial and continues throughout the trial. Evidence that can be used to challenge the credibility of prosecution witnesses must also be disclosed.

If a Brady violation is found, possible remedies include the reversal of a conviction, a new trial, or other appropriate sanctions. Failure to disclose material exculpatory evidence constitutes a violation of the defendant's due process rights under the Fourteenth Amendment.

The prosecution's intentions do not affect the Brady analysis. Whether the non-disclosure was intentional or inadvertent, it is still a violation if the evidence was material and exculpatory.

The obligation extends to evidence known to all members of the prosecution team, including police and other investigative agencies. The prosecution is deemed to have constructive knowledge of evidence in its control.
