With no explanation, chose the best option from "A", "B", "C" or "D". by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.” Brady, 373 U.S. at 87, 83 S.Ct. 1194. The Supreme Court later held in United States v. Agurs, 427 U.S. 97, 96 S.Ct. 2392, 49 L.Ed.2d 342 (1976), that "the duty to disclose such evidence is applicable even though there has been no request by the accused.” Strickler v. Greene, 527 U.S. 263, 280, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999) (citing Agurs, 427 U.S. at 107, 96 S.Ct. 2392). 4 . Hurst also makes a passing reference in his brief to a Giglio claim in relation to Smith’s trial testimony. See Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972) (<HOLDING>). We find this claim to be without merit
