Revise public service commission membership

SB 561 revises Montana's Public Service Commission membership structure, changing it from five elected members to two elected commissioners (from five districts) plus three governor-appointed commissioners. The bill requires commission districts to align with federal congressional districts after each census, mandates that appointed commissioners have no recent ties to regulated industries, and limits service to 12 years in a 24-year period for all members. It also adds new rules for filling vacancies, requiring gubernatorial appointments to match the former commissioner's party (if applicable) and prohibiting financial conflicts of interest for appointees. The bill aims to modernize the commission's composition and reduce potential industry influence.
