What is relevant evidence in a sexual assault case?

" 'Relevant evidence' means evidence, including evidence relevant to the credibility of a witness or hearsay declarant, having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Evid. Code, 210.) " 'Except as otherwise provided by statute, all relevant evidence is admissible.' [Citations.] 'Evidence is relevant if it tends " 'logically, naturally, and by reasonable inference' to establish material facts ...." ' [Citation.]" (People v. Clark (2011) 52 Cal.4th 856, 892.)

Evidence of a defendant's prior acts is inadmissible when offered to show that he had the criminal disposition or propensity to commit the charged offense. However, such evidence is admissible when relevant to establish some fact other than character or disposition, such as motive or intent, if the acts are sufficiently similar. The least degree of similarity is required in order to prove intent. (People v. Ewoldt (1994) 7 Cal.4th 380, 393, 402; People v. Fuiava (2012) 53 Cal.4th 622, 667.)

"A trial court may exclude otherwise relevant evidence when its probative value is substantially outweighed by concerns of undue prejudice, confusion, or consumption of time. [Citations.]" (People v. Scott (2011) 52 Cal.4th 452, 490.)
