What is the test for admissible evidence of prior criminal activity?

19 Compare People v. Griffin (1963) 60 Cal.2d 182, 191, 32 Cal.Rptr. 24, 383 P.2d 432, holding admissible evidence of a prior crime for which defendant obtained an acquittal. This ruling was explicitly overruled by the language of former section 190.3, providing that "in no event shall evidence of prior criminal activity be admitted for an offense for which the defendant was prosecuted and was acquitted." Accord, People v. Terry, supra, 61 Cal.2d at pp. 147-148, 37 Cal.Rptr. 605, 390 P.2d 381 (holding inadmissible evidence of a prior conviction for which defendant received a pardon).
