Revise vote requirement to enact constitutional amendment by legislative referendum

This bill proposes to change Montana's constitutional amendment process by increasing the number of legislative votes required to approve a constitutional amendment through a legislative referendum. Currently, the state constitution allows amendments to be proposed by the legislature and submitted to voters if approved by a two-thirds vote, but this bill seeks to clarify and potentially adjust that threshold. The measure would be submitted to Montana voters at the November 2026 general election for approval. If passed by voters, the change would affect how future constitutional amendments are initiated and approved by the state legislature.
