Revise public service commission membership

This bill (LC 4454) revises how Montana's Public Service Commission is structured and staffed. It changes the commission to include two elected members (chosen from five districts based on federal congressional districts) and three members appointed by the governor with Senate confirmation. The bill also shortens elected terms to four years (from six), establishes a 12-year term limit for both elected and appointed commissioners, and requires governors to appoint vacancy fillers from the same political party as the former commissioner when possible. These changes directly affect Montana residents (through district representation), the Public Service Commission, governors, and political parties.
