What is the test for "vidence" in a criminal case?

"[E]vidence is favorable if it helps the defense or hurts the prosecution." (People v. Zambrano (2007) 41 Cal.4th 1082, 1132.) Materiality requires a defendant to ". . . 'show a "reasonable probability of a different result." ' [Citation.]" (Salazar, supra, 35 Cal.4th at p. 1043), i.e., that the evidence "could reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict." (Kyles v. Whitley (1995) 514 U.S. 419, 435.)
