Whether the prosecution’s suppression, after a defense request, of Boblit’s statement admitting the actual killing violated Brady’s Fourteenth Amendment right to due process.
Holding
Yes. The prosecution violates due process when it suppresses requested evidence favorable to the accused that is material to guilt or punishment, regardless of the prosecutor’s good faith or bad faith.
Reasoning
The Court treated the case as an extension of its precedents forbidding convictions procured through the knowing use of perjured evidence or the deliberate suppression of favorable evidence. Those cases reflect a broader constitutional concern: a criminal conviction cannot rest on a process distorted by the State’s concealment of evidence helpful to the defense.
Boblit’s statement was favorable to Brady because it supported Brady’s claim that Boblit, not Brady, had performed the killing. Even if the statement did not eliminate Brady’s liability for felony murder, it could influence the jury’s decision whether to impose death or life imprisonment.
The constitutional rule is aimed at protecting the fairness of the trial, not at punishing prosecutorial misconduct. Thus, the prosecutor’s lack of guile did not excuse the nondisclosure. Justice requires disclosure of requested, material favorable evidence because the government’s interest is not simply to obtain convictions, but to ensure that justice is done.
