Can courts exclude evidence of a child victim's sexual history in Utah criminal cases? State v. Ashby Explained

In State v. Ashby, the Utah Court of Appeals addressed when trial courts may exclude evidence of a child victim’s sexual behavior with others in criminal sexual abuse cases, providing important guidance on the application of Utah Rule of Evidence 412.

Background and Facts

Ashby was charged with two counts of aggravated sexual abuse of a child based on allegations that she bathed naked with an eight-year-old boy and engaged in sexual touching. The child disclosed the abuse during a forensic interview at the Children’s Justice Center. Before trial, Ashby sought to introduce evidence that the child had engaged in sexual behavior with six other children, arguing this evidence was necessary to rebut the sexual innocence inference, impeach the child’s credibility, and show he had opportunities to disclose abuse earlier but failed to do so.

Key Legal Issues

The case presented two primary issues: (1) whether the trial court properly excluded evidence of the child’s sexual behavior with others under Rules 412 and 403, and (2) whether the court erred in allowing the jury to take the DVD of the child’s forensic interview into deliberations under Rule 17(l) of the Utah Rules of Criminal Procedure.

Court’s Analysis and Holding

The Court of Appeals affirmed the trial court’s exclusion of the evidence. While acknowledging the evidence was relevant under Utah’s “very low” relevance threshold, the court found the exclusion was proper under both Rule 412 and Rule 403. Under Rule 412, the court emphasized that the rule’s purposes—protecting child victims from embarrassment and encouraging reporting of sexual crimes—were strongly served by exclusion. The court noted that even if the evidence could be introduced through other witnesses, Rule 412 protects against public disclosure regardless of the source.

Under Rule 403, the court found the evidence’s probative value was substantially outweighed by potential prejudice. Critically, the court determined that the child’s sexual behavior with others was not sufficiently similar to the charged conduct—the other incidents involved primarily oral stimulation between males, while the charged acts involved manual touching and digital penetration. Regarding the DVD issue, the court found any error harmless because there was no evidence the jury actually watched the recording during deliberations, as no DVD player was provided.

Practice Implications

This decision reinforces that Utah courts will carefully scrutinize attempts to introduce evidence of a child victim’s other sexual behavior. The similarity analysis is crucial—practitioners must demonstrate substantial similarity between prior conduct and charged acts to establish meaningful probative value for rebutting the sexual innocence inference. The ruling also confirms that Rule 412’s protective purposes receive broad construction in cases involving child victims, making alternative impeachment methods essential for defense counsel.
