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 or potential disclosure of the victim's gender identity or sexual orientation, including situations where the victim made a romantic advance or had a prior relationship with the defendant.

Additionally, the bill clarifies that mental disease or defect does not include conditions arising from the same circumstances related to a victim's gender identity or sexual orientation. The legal language has been updated to reflect these changes, including the creation of new sections in the statutes that define these limitations on defenses. The bill is set to apply to offenses committed on or after its effective date.
