Montana offers three different paths to having a constitutional convention. They are:
•Section 1, Article XIV says that the Montana State Legislature, “by an affirmative vote of two-thirds of all the members ... may at any time submit to the qualified electors the question of whether there shall be an unlimited convention to revise, alter, or amend” the constitution. •Section 2, Article XIV says that the state’s electors can put a question about whether to hold a convention on a statewide ballot if a petition is signed by at least ten percent of the qualified electors of the state, including at least ten percent of the qualified electors in each of two-fifths of the legislative districts. •Section 3, Article XIV says that a question about whether to hold a convention shall automatically go on the ballot every twenty years if it has not otherwise appeared on the ballot. The Montana State Legislature can put a legislatively-referred constitutional amendment on the ballot, according to Section 8 of Article XIV. Any member of the legislature can propose an amendment. The amendment must then be adopted by an affirmative roll call vote of two-thirds of all members of the legislature.
