sexual offenses; victim; evidence

SB 1669 restricts the use of a sexual assault victim's past sexual history as evidence in court, generally barring reputation or opinion evidence about their chastity. It allows limited exceptions only for evidence about the victim's past sexual conduct with the defendant, specific instances showing the source of physical evidence (like semen or pregnancy), evidence supporting a motive for false accusations, impeachment of the victim, or prior false allegations against others. Before any such evidence can be presented, a judge must hold a pretrial hearing and determine admissibility using the "clear and convincing evidence" standard. This law directly affects criminal trials for sexual offenses under Arizona statutes (including sections 13-1421, 13-3212, and chapter 35), aiming to limit prejudicial questioning of victims.
