Brady v. Maryland
373 U.S. 83 (1963)
Holding
The prosecution violates due process when it suppresses evidence favorable to the accused that is material to guilt or punishment, regardless of the prosecutor's good faith or bad faith.
What Happened
John Brady and a companion, Charles Boblit, were prosecuted separately for murder committed during a robbery. Brady admitted taking part in the crime but argued that Boblit did the actual killing. Before trial, Brady’s lawyer asked to inspect Boblit’s statements.
The prosecution turned over some of Boblit’s statements but withheld one in which Boblit admitted committing the homicide himself. That statement did not erase Brady’s own involvement in the robbery, but it mattered to punishment because Maryland law allowed the jury to choose between life imprisonment and death.
After Brady was convicted and sentenced to death, the suppressed statement surfaced. Maryland’s highest court held that the suppression violated due process, but it limited the remedy to a new trial on punishment rather than guilt. The Supreme Court took the case to decide the constitutional rule.
What the Court Decided
The Supreme Court held that due process is violated when the prosecution suppresses evidence favorable to the accused and material to guilt or punishment. The Court made two points that still define Brady doctrine:
- Favorable evidence must be disclosed. The State cannot keep back evidence that helps the defense on guilt or punishment.
- Good faith does not save the suppression. The constitutional problem turns on the effect of withholding favorable evidence, not on whether the prosecutor acted maliciously or innocently.
The Court agreed that Brady was entitled to relief. But because the withheld statement went only to punishment under the Maryland court’s view of the case, the Court allowed the remedy to be limited to a new sentencing proceeding rather than a full retrial on guilt.
What It Means in Practice
Brady is the foundation of the modern disclosure rule in criminal cases. It established that the government has an affirmative constitutional duty to disclose favorable, material evidence.
For a Section 1983 site, the practical point is larger than the original facts. Brady became the starting point for later cases explaining:
- that impeachment evidence counts, not just directly exculpatory evidence
- that police knowledge can be imputed to the prosecution team
- that materiality looks to whether the suppression undermines confidence in the outcome
That is why Brady matters in wrongful prosecution, fabricated-evidence, and police-suppression cases.
How You Can Use It
- Use it to identify the core due process theory. If favorable evidence was hidden and the suppression mattered to the result, Brady is the doctrinal starting point.
- Use it to frame the issue correctly. The question is not just whether the government acted badly. The question is whether the suppressed evidence was favorable and material.

How It Can Be Used Against You
- Materiality is still required. Defendants will argue the hidden evidence would not have changed anything important.
- The original case was about criminal process, not civil damages. In a Section 1983 case, you still need a viable civil theory against the right defendant.
- Prosecutorial immunity remains a barrier. Even when a Brady violation occurred, damages claims against prosecutors often run into absolute immunity.
How to counter: Tie the suppressed evidence to a concrete theory of prejudice. Show how it would have changed plea decisions, cross-examination, trial strategy, or the verdict itself. And in civil litigation, focus carefully on which actors possessed the evidence and who can actually be sued.
