What is the current state of the law regarding conflicting evidence in a sexual assault case?

The existence of conflicting evidence does not warrant a reversal of the convictions. "Conflicts and even testimony which is subject to justifiable suspicion do not justify the reversal of a judgment, for it is the exclusive province of the trial judge or jury to determine the credibility of a witness and the truth or falsity of the facts upon which a determination depends." (People v. Maury ( 2003) 30 Cal.4th 342, 403.) A reviewing court may not substitute its evaluation of a witness's credibility for that of the fact finder. (People v. Ochoa (1993) 6 Cal.4th 1199, 1206.)
