Utah Supreme Court

When can Utah courts admit evidence of a defendant's prior crimes? State v. Doporto Explained

1997 UT
No. 940014
January 17, 1997
Reversed

Summary

Doporto was convicted of sodomy on a child and sentenced to fifteen years to life. The trial court admitted testimony from two other alleged victims regarding prior sexual abuse incidents under Rule 404(b). The Supreme Court found the prior crime evidence was improperly admitted because it lacked probative value beyond showing criminal propensity.

Analysis

The Utah Supreme Court in State v. Doporto significantly tightened the standards for admitting evidence of a defendant’s prior crimes, establishing heightened protection against prejudicial evidence that can unfairly influence juries.

Background and Facts

Doporto was charged with sodomy on a child involving a seven-year-old victim. The state sought to introduce testimony from two other alleged victims under Rule 404(b) to prove motive, opportunity, intent, or common plan. The trial court allowed the testimony after finding sufficient similarities between the incidents. Doporto represented himself throughout the proceedings after being denied appointed counsel.

Key Legal Issues

The primary issue was whether the trial court properly admitted prior crime evidence under Rule 404(b). The court also addressed the appropriate standard of review for such evidentiary rulings, examining whether trial courts should receive broad or limited deference on these determinations.

Court’s Analysis and Holding

The Supreme Court held that prior crime evidence is presumed inadmissible and requires special justification. Before admitting such evidence, trial courts must find: (1) necessity for the evidence, (2) high probativeness of a material issue, and (3) that probative value outweighs prejudicial effect. The court found the prior incidents showed only similarities common to many child abuse cases—not the “peculiarly distinctive” conduct required under State v. Featherson. The prosecutor’s closing argument explicitly invited the prohibited inference that Doporto’s criminal propensity made him likely to commit the charged crime.

Practice Implications

The decision establishes that appellate courts will review Rule 404(b) determinations with “very limited deference” rather than broad discretion. Practitioners opposing prior crime evidence should emphasize that similarities must be uniquely distinctive, not merely common to that crime type. The ruling also warns prosecutors against arguing criminal propensity in closing arguments, even when prior crime evidence is properly admitted.
