What principles apply to materials that might alter the credibility of a significant prosecution witness?
MultiRegion, United States of America
The following excerpt is from Perkins v. Le Fevre, 691 F.2d 616 (2nd Cir. 1982):
427 U.S. at 106, 96 S.Ct. at 2399. These principles apply both to materials going to the heart of the defendant's guilt or innocence and to materials that might well alter the jury's judgment of the credibility of a significant prosecution witness. See Giglio v. United States, 405 U.S. 150, 154, 92 S.Ct. 763, 766, 31 L.Ed.2d 104 (1972); Napue v. Illinois, 360 U.S. 264, 269, 79 S.Ct. 1173, 1177, 3 L.Ed.2d 1217 (1959).
