The general assembly, by a vote of a majority of the members elected to each house, may at any general election submit the question, ”Shall there be a convention to amend or revise the Constitution?” to the qualified electors of the state. If the question be not submitted to the people at some time during any period of ten years, the secretary of state shall submit it at the next general election following said period. Prior to a vote by the qualified electors on the holding of a convention, the general assembly, or the governor if the general assembly fails to act, shall provide for a bi-partisan preparatory commission to assemble information on constitutional questions for the electors. If a majority of the electors voting at such election on said question shall vote to hold a convention, the general assembly at its next session shall provide by law for the election of delegates to such convention. The number of delegates shall be equal to the number of members of the house of representatives and shall be apportioned in the same manner as the members of the house of representatives. No revision or amendment of this Constitution agreed upon by such convention shall take effect until the same has been submitted to the electors and approved by a majority of those voting thereon.
