In "Brady v. Maryland" it was ruled that the suppression of evidence favorable to an accused violates due process, irrespective of the good or bad faith of the prosecutor, where such evidence is material to the guilt or punishment of the accused. The failure of the government to produce exculpatory evidence may or may not fall within the confines of the Jencks Act. In some cases, the production of documents must be made at a time prior to that required by the Jencks Act. The Brady rule may require the prosecutor to disclose grand jury testimony prior to trial, if the information is exculpatory, as well as other Brady material.
