Generally revise partner family member assault laws to prevent victim from being charged with assault

This bill revises Montana's partner or family member assault laws to clarify that individuals acting in self-defense against an assault are considered victims and cannot be charged with the assault themselves. It directly affects people who may have been involved in a conflict with a partner or family member where they defended themselves from physical harm or threats. The key provision explicitly defines a "victim" to include anyone acting in self-defense, ensuring they are not prosecuted for the assault they were defending against. The bill also maintains existing penalties for offenders, including fines, jail time, and mandatory counseling requirements, while updating definitions of family members and partners to include various relationship types.
