Rule 413. Similar Crimes in Sexual-Assault Cases

(a) Permitted Uses. In a criminal case in which a defendant is accused of a sexual assault, the court may admit evidence that the defendant committed any other sexual assault. The evidence may be considered on any matter to which it is relevant.

(b) Disclosure to the Defendant. If the prosecutor intends to offer this evidence, the prosecutor must disclose it to the defendant, including witnesses’ statements or a summary of the expected testimony. The prosecutor must do so at least 15 days before trial or at a later time that the court allows for good cause.

(c) Effect on Other Rules. This rule does not limit the admission or consideration of evidence under any other rule.

1. any conduct prohibited by 18 U.S.C. chapter 109A;
