Brady v. Maryland

Background

Brady was tried separately from his companion Boblit, and both were convicted of first‑degree murder and sentenced to death. Brady admitted participating but said Boblit did the killing. Defense counsel asked to see Boblit’s statements; one July 9 confession in which Boblit admitted the homicide was withheld by the prosecution and only discovered after Brady’s conviction. The Maryland Court of Appeals ordered a new trial limited to punishment.

Reasoning

The Court considered whether the suppression of that confession violated the Fourteenth Amendment and whether limiting a retrial to punishment denied a federal right. Relying on earlier decisions, the Court held that prosecutors must disclose evidence favorable to an accused when it is material to guilt or to punishment, irrespective of the prosecutor’s good or bad faith. The majority read Maryland law to mean the suppressed confession would not have reduced Brady’s offense below first‑degree murder and therefore affirmed the limited new trial on punishment.

Real world impact

The decision requires prosecutors to turn over requested exculpatory evidence that could affect guilt or sentencing, and it makes clear disclosure is required even if the prosecutor acted in good faith. Defendants, defense lawyers, and prosecutors are directly affected. State rules about whether a judge or a jury decides admissibility may influence whether a retrial covers only punishment or also guilt.

Dissents or concurrances

Justice White concurred in the result but warned the Court need not announce a broad new discovery rule and preferred leaving larger changes to rulemaking or legislation. Justice Harlan, joined by Justice Black, dissented and would have remanded to the state court for clarification of state law on admissibility.
