How is the standard of review applied in a motion for sexual assault?

We begin with the standard of review. Determination of whether evidence is relevant is left to the "sound discretion of the trial court, and the exercise of that discretion will not be reversed absent a showing of abuse. [Citations.] That discretion is only abused where there is a clear showing the trial court exceeded the bounds of reason, all of the circumstances being considered." (People v. DeJesus (1995) 38 Cal.App.4th 1, 32.)
