United States v. Agurs

1976-06-24

Headline: Limits prosecutors’ duty to volunteer evidence by ruling undisclosed victim convictions did not warrant a new trial, making it harder for defendants to get retrials unless omissions create new reasonable doubt.

Holding: The Court held that failing to disclose the victim's prior convictions did not violate the defendant's right to a fair trial because the omitted records, viewed in the whole record, did not create a new reasonable doubt.

Real World Impact:

Makes it harder to get a new trial when prosecutors don't volunteer undisclosed evidence.
Requires judges to weigh omitted evidence in the full trial record before ordering retrial.
Encourages prosecutors to disclose doubtful items but not hand over entire files.

Summary

Background

A woman was convicted of second-degree murder after repeatedly stabbing James Sewell in a motel room. Witnesses found Sewell on top of the woman struggling over a knife; Sewell died and the woman offered no testimony. Her lawyer argued self-defense, pointing to screams for help, Sewell’s two knives, and defensive wounds on Sewell. After conviction, defense counsel discovered Sewell had prior guilty pleas for assault and carrying a deadly weapon in 1963 and 1971 and claimed the prosecutor had not disclosed those records.

Reasoning

The Court considered whether the prosecutor must volunteer exculpatory information when defense counsel did not request it and what standard applies. The Court described three Brady-type situations and held that prosecutors need not give the defense their whole file. The constitutional test for nondisclosure is whether the omitted evidence, considered in the context of the entire trial record, would create a reasonable doubt that did not otherwise exist. The trial judge had reviewed the full record and found no such reasonable doubt, so the prosecutor’s failure to disclose did not deny a fair trial.

Real world impact

The ruling means judges, not prosecutors, evaluate whether undisclosed material would have produced a reasonable doubt when viewed with all other evidence. Prosecutors are encouraged to disclose doubtful items, but are not constitutionally required to volunteer every investigatory detail. Defendants seeking a new trial must show the omission would have produced a reasonable doubt, not merely that the evidence might have helped.

Dissents or concurrances

Justice Marshall (joined by Justice Brennan) dissented, arguing the Court’s standard is too narrow and would make it harder to hold prosecutors accountable for withholding evidence favorable to defendants.
