HB0121: Rules for Using Past Sexual Assault Evidence in Court

Last scannedOct 19, 2026, 2:19 AM

In one sentence

This bill proposed specific rules for when courts could allow evidence of a person's past sexual assaults to be used in new criminal or civil cases involving sexual assault.

What it does

  • Allows evidence of prior sexual assaults to be considered in civil cases where a claim is based on an alleged sexual assault.
  • Allows evidence of prior sexual assaults to be considered in criminal cases where the defendant is accused of a sexual assault.
  • Requires a party to file a written motion and affidavits at least 15 days before the scheduled start of trial to offer this evidence.
  • Requires the judge to hold a private hearing (in chambers) to decide if the evidence is relevant and fair.
  • Requires the judge to determine that the evidence's usefulness substantially outweighs the risk of unfair prejudice before allowing it.
  • Defines 'offense of sexual assault' to include attempts or conspiracies to commit such acts, as well as similar offenses from other jurisdictions.

Who it affects

  • Courts in Wyoming handling criminal or civil sexual assault cases.
  • Lawyers and parties involved in these specific legal proceedings.
  • Defendants or accused parties in sexual assault cases.

Limits and unknowns

  • The bill did not pass and did not become law.
  • The bill does not change how evidence is handled in cases that are not about sexual assault.
  • The bill does not specify penalties for failing to follow the 15-day notice requirement.
