Provide for article V commissioner selection and oversight

Montana's SB 120 establishes rules for selecting, overseeing, and recalling state delegates to a potential Article V constitutional convention. It requires commissioners to meet specific qualifications (e.g., 10 years U.S. citizenship, 5 years Montana residency, no recent federal roles) and prohibits them from supporting changes to the "one state, one vote" rule or amending key constitutional protections like the Bill of Rights. The bill mandates a legislative resolution defining commissioners' limited authority (based on Montana's application or prior state applications) and creates an advisory committee to manage vacancies and enforce boundaries. The bill died in committee in May 2025 and did not become law.
