What is the case law on prejudicial evidence in a sexual assault case?

We conclude the evidence was not unduly prejudicial when balanced against its relevance. "Without doubt, evidence a defendant committed an offense on a separate occasion is inherently prejudicial. [Citations.] But Evidence Code section 352 requires the exclusion of evidence only when its probative value is substantially outweighed by its prejudicial effect. 'Evidence is substantially more prejudicial than probative . . . [only] if, broadly stated, it poses an intolerable "risk to the fairness of the proceedings or the reliability of the outcome" [citation]' [Citation.]" (People v. Quang Minh Tran (2011) 51 Cal.4th 1040, 1047.)
