Can Utah courts admit expert testimony about sexual assault victim behaviors? State v. Francis Explained

In State v. Francis, the Utah Court of Appeals addressed the admissibility of expert testimony regarding common behaviors and characteristics of sexual assault victims, providing important guidance for practitioners handling sexual abuse cases.

Background and Facts

Rex Francis was convicted of two counts of forcible sexual abuse and one count of object rape involving two teenage victims. The State called an expert witness to testify about common responses of sexual assault victims, including delayed reporting, self-blame, and various trauma responses. Francis objected under Rules 702 and 403, arguing the testimony lacked sufficient reliability and constituted improper anecdotal statistical evidence.

Key Legal Issues

The court addressed multiple evidentiary and instructional issues: (1) whether expert testimony about sexual assault victim behaviors satisfied Rule 702’s reliability requirements; (2) whether such testimony violated Rule 403’s prejudice concerns; (3) whether defense counsel could elicit both reputation and opinion testimony about a victim’s truthfulness under Rule 608(a); and (4) whether defendants are entitled to lesser included offense instructions and unanimity instructions on theories of nonconsent.

Court’s Analysis and Holding

The court affirmed admission of the expert testimony, noting several key factors. The expert testified as a blind witness, explicitly stating he knew nothing about the case facts or parties. He spoke in generalities about common victim responses rather than offering concrete percentages or direct opinions on truthfulness. The expert’s qualifications included extensive professional experience and familiarity with relevant literature. The court distinguished cases like State v. Rammel and State v. Burnett, which prohibited anecdotal statistical evidence used to assess credibility, emphasizing that this expert avoided such problematic testimony.

However, the court found two trial errors: improperly sustaining an objection to defense counsel’s question about the witness’s opinion of a victim’s character for truthfulness, and failing to give a requested lesser included offense instruction. The court concluded Rule 608(a) permits both reputation and opinion testimony about truthfulness, using the inclusive rather than exclusive meaning of “or.”

Practice Implications

This decision provides a framework for admitting expert testimony about trauma responses while avoiding Rule 403 problems. Experts should testify as blind witnesses, speak in generalities about common victim behaviors, and avoid concrete statistics that suggest scientific precision about truthfulness. Defense counsel should ensure they exhaust both reputation and opinion avenues under Rule 608(a) when attacking witness credibility. The court’s harmless error analysis demonstrates the importance of corroborating evidence and the cumulative impact of multiple similar victim accounts in sexual abuse prosecutions.
