Revise laws on sexual assault

This bill revises Montana's sexual assault laws by increasing penalties for repeat offenders and clarifying consent rules in specific situations. It directly affects people convicted of sexual assault and individuals in vulnerable positions such as students, mental health patients, and therapy clients. The key changes include raising maximum jail sentences for second and third offenses, establishing mandatory sex offender registration for repeat offenders, and defining consent as ineffective when a perpetrator holds authority over a victim in settings like schools, youth care facilities, or therapy offices. The bill also maintains exceptions for married couples in most authority-based scenarios.
