Rule 404. Character evidence not admissible to prove conduct; exceptions; other crimes.

(a) Character evidence generally. Evidence of a person's character or a trait of character is not admissible for the purpose of proving action in conformity therewith on a particular occasion, except:

(a)(1) Character of accused. Evidence of a pertinent trait of character offered by an accused, or by the prosecution to rebut the same, or if evidence of a trait of character of the alleged victim of the crime is offered by the accused and admitted under Rule 404(a)(2), evidence of the same trait of character of the accused offered by the prosecution;

(a)(2) Character of alleged victim. Evidence of a pertinent trait of character of the alleged victim of the crime offered by an accused, or by the prosecution to rebut the same, or evidence of a character trait of peacefulness of the alleged victim offered by the prosecution in a homicide case to rebut evidence that the alleged victim was the first aggressor;

(a)(3) Character of witness. Evidence of the character of a witness, as provided in Rules 607, 608, and 609.

(b) Other crimes, wrongs, or acts. Evidence of other crimes, wrongs or acts is not admissible to prove the character of a person in order to show action in conformity therewith. It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident, provided that upon request by the accused, the prosecution in a criminal case shall provide reasonable notice in advance of trial, or during trial if the court excuses pretrial notice on good cause shown, of the nature of any such evidence it intends to introduce at trial.

(c) Evidence of similar crimes in child molestation cases.

(c)(1) In a criminal case in which the accused is charged with child molestation, evidence of the commission of other acts of child molestation may be admissible to prove a propensity to commit the crime charged provided that the prosecution in a criminal case shall provide reasonable notice in advance of trial, or during trial if the court excuses pretrial notice on good cause shown, of the nature of any such evidence it intends to introduce at trial.

(c)(2) For purposes of this rule “child molestation” means an act committed in relation to a child under the age of 14 which would, if committed in this state, be a sexual offense or an attempt to commit a sexual offense.

(c)(3) Rule 404(c) does not limit the admissibility of evidence otherwise admissible under Rule 404(a), 404(b), or any other rule of evidence.

Advisory Committee Note. Rule 404(a)-(b) is now Federal Rule of Evidence 404 verbatim. The 2001 amendments add the notice provisions already in the federal rule, add the amendments made to the federal rule effective December 1, 2000, and delete language added to the Utah Rule 404(b) in 1998. However, the deletion of that language is not intended to reinstate the holding of State v. Doporto, 935 P.2d 484 (Utah 1997). Evidence sought to be admitted under Rule 404(b) must also conform with Rules 402 and 403 to be admissible.

The 2008 amendment adds Rule 404(c). It applies in criminal cases where the accused is charged with a sexual offense against a child under the age of 14. Before evidence may be admitted under Rule 404(c), the trial court should conduct a hearing out of the presence of the jury to determine: (1) whether the accused committed other acts, which if committed in this State would constitute a sexual offense or an attempt to commit a sexual offense; (2) whether the evidence of other acts tends to prove the accused’s propensity to commit the crime charged; and (3) whether under Rule 403 the danger of unfair prejudice substantially outweighs the probative value of the evidence, or whether for other reasons listed in Rule 403 the evidence should not be admitted. The court should consider the factors applicable as set forth in State v. Shickles, 760 P.2d 291, 295-96 (Utah 1988), which also may be applicable in determinations under Rule 404(b).

Upon the request of a party, the court may be required to provide a limiting instruction for evidence admitted under Rule 404(b) or (c).
