What is the current state of the law on the power of a trial court to dismiss or dismiss an allegation of sexual assault?

"Under Evidence Code section 352, the trial court enjoys broad discretion in assessing whether the probative value of particular evidence is outweighed by concerns of undue prejudice, confusion or consumption of time. [Citation.] Where, as here, a discretionary power is statutorily vested in the trial court, its exercise of that discretion `must not be disturbed on appeal except on a showing that the court exercised its discretion in an arbitrary, capricious or patently absurd manner that resulted in a manifest miscarriage of justice. [Citations.]' [Citation.]" (People v. Rodrigues, supra, 8 Cal.4th at pp. 1124-1125, italics in original.)
