Senate Bill 380 aims to amend current criminal law in Wisconsin by eliminating certain defenses related to adequate provocation, self-defense, and mental disease or defect when these claims are based on a victim's gender identity or sexual orientation. Specifically, the bill stipulates that a defendant cannot assert adequate provocation or self-defense if their actions stem from the discovery of, knowledge about, or potential disclosure of the victim's gender identity or sexual orientation, particularly in situations where the victim made a romantic or sexual advance without force or violence.

Additionally, the bill clarifies that a mental disease or defect defense does not apply if it is caused by the same factors related to the victim's gender identity or sexual orientation. The bill includes new legal language that defines these exclusions and renumbers existing statutes to incorporate these changes. The provisions will take effect for offenses committed on or after the bill's effective date.
