Can Utah courts admit expert testimony about child sexual abuse disclosure patterns? State v. Martin Explained

In State v. Martin, the Utah Supreme Court addressed the admissibility of expert testimony regarding child sexual abuse victims’ behavior and disclosure patterns, providing important guidance for practitioners handling these sensitive cases.

Background and Facts

Joshua Martin was convicted of four counts of aggravated sexual abuse of a child for sexually abusing his sisters-in-law while occupying a position of special trust. The victims made inconsistent initial disclosures about the abuse, prompting the prosecution to call a forensic interviewer from the Children’s Justice Center as an expert witness. The expert testified about why children make incomplete initial disclosures and explained the varied behavioral responses of child abuse victims. Martin challenged this testimony on appeal, arguing it exceeded the expert’s qualifications and improperly bolstered the victims’ credibility.

Key Legal Issues

The court addressed three main evidentiary issues: (1) whether the expert’s testimony about child memory and recall exceeded her expertise, (2) whether expert testimony about child disclosure patterns and behaviors was helpful and reliable under Rule 702, and (3) whether such testimony improperly invaded the jury’s province by bolstering witness credibility.

Court’s Analysis and Holding

The supreme court affirmed the trial court’s evidentiary rulings. Regarding the expert’s testimony about memory, the court found Martin failed to preserve his objection by not specifically objecting during trial. On the substantive admissibility question, the court applied an abuse of discretion standard and concluded the expert testimony was properly admitted. The court noted that testimony about why child victims make inconsistent disclosures could help jurors who might otherwise expect complete initial disclosures. However, the court acknowledged ongoing debates in other jurisdictions about the scientific reliability of such testimony and urged careful consideration of the evidence presented by parties.

Practice Implications

This decision highlights the importance of proper preservation when challenging expert testimony scope. Defense counsel must make specific objections to testimony that allegedly exceeds an expert’s qualifications, rather than relying on general challenges. The court’s nuanced approach suggests that while such expert testimony may be admissible, practitioners should be prepared to present concrete evidence about reliability and potential prejudice when seeking to exclude it.
