The district court denied Giglio’s motion for a new trial, finding that the error did not affect the verdict. The Court of Appeals affirmed.<p>Yes. Chief Justice Warren E. Burger, writing for a unanimous court, reversed the conviction and remanded the case for a new trial. The Supreme Court held that evidence of the agreement was relevant to the witness’ credibility. Because the new evidence affected the witness’ credibility and the prosecution’s case rested almost entirely on this witness’ testimony, the original trial violated due process and entitled Giglio to a new trial. Justice Lewis F. Powell and Justice William H. Rehnquist did not participate.</p> Yes. Chief Justice Warren E.
