Relating to: prohibiting possessing a firearm on college and university campuses and providing a penalty.

AB 427 prohibits possessing a firearm on university or college campus property, including buildings and grounds owned or leased by the institution. It establishes a Class A misdemeanor charge for violations, with specific exceptions for law enforcement officers, military personnel on duty, individuals leasing residential or business spaces on campus, and firearms in approved programs or locked vehicles. The bill directly affects anyone on campus property - students, staff, visitors - by restricting firearm possession where it was previously not specifically prohibited under state law. Key mechanisms include creating new legal language (941.236) to define campus firearm rules and amending related statutes to clarify campus exemptions.
