Can other acts evidence be excluded under rule 403 in child molestation cases? State v. Estes Explained

In State v. Estes, the Utah Court of Appeals addressed the admissibility of other acts evidence in child molestation cases under rules 404(c) and 403 of the Utah Rules of Evidence. The case provides important guidance on how courts should balance probative value against unfair prejudice when propensity evidence is specifically permitted.

Background and Facts

Ryan Estes was convicted of aggravated sexual abuse of a child based on testimony from his stepdaughter Beth about abuse that occurred in their Clinton home. The State sought to introduce testimony from Estes’s daughter Kate about separate acts of abuse she suffered at the hands of Estes. The district court admitted Kate’s testimony under rule 404(c), which permits evidence of other acts of child molestation to prove propensity in child molestation cases.

Key Legal Issues

Estes challenged the admission of Kate’s testimony under rule 403, arguing it was substantially more unfairly prejudicial than probative. He also argued that Beth’s testimony was inherently improbable due to temporal inconsistencies—she testified the abuse occurred in summer 2016 but in the Clinton home, when the family had moved from Clinton to Roy in 2015.

Court’s Analysis and Holding

The court rejected both challenges. Regarding the rule 403 analysis, the court emphasized that evidence’s tendency to prove propensity cannot be weighed on the prejudice side when rule 404(c) specifically permits propensity evidence. The court noted that Kate’s testimony inevitably bolstered Beth’s credibility, but this bolstering was “intrinsic to Estes’s propensity”—the evidence cannot show propensity without making the victim’s story more believable. The court found no unfair prejudice beyond the propensity nature of the evidence.

On the sufficiency challenge, the court found Beth’s testimony was not inherently improbable. While Beth was uncertain about dates, she was certain about the location. The court noted that children often cannot reliably identify when past events occurred, and the district court reasonably found her location testimony credible despite temporal inconsistencies.

Practice Implications

This decision clarifies the proper rule 403 analysis in the rule 404(c) context. Practitioners challenging other acts evidence must identify specific unfair prejudice beyond the evidence’s propensity nature. The mere fact that propensity evidence makes a victim more believable cannot constitute unfair prejudice, as that is the precise purpose of rule 404(c). The decision also demonstrates courts’ recognition that child victims may have imperfect memories regarding timing while maintaining credibility on other details.
