Section 1. The Legislative Assembly may propose amendments to this Constitution by a concurrent resolution approved by not less than two-thirds of the total number of members of which each house is composed. All proposed amendments shall be submitted to the qualified electors in a special referendum, but if the concurrent resolution is approved by not less than three-fourths of the total number of members of which each house is composed, the Legislative Assembly may provide that the referendum shall be held at the same time as the next general election. Each proposed amendment shall be voted on separately and not more than three proposed amendments may be submitted at the same referendum. Every proposed amendment shall specify the terms under which it shall take effect, and it shall become a part of this Constitution if it is ratified by a majority of the electors voting thereon. Once approved, a proposed amendment must be published at least three months prior to the date of the referendum.

The Legislative Assembly, by a concurrent resolution approved by two-thirds of the total number of members of which each house is composed, may submit to the qualified electors at a referendum, held at the same time as a general election, the question of whether a constitutional convention shall be called to revise this Constitution. If a majority of the electors voting on this question vote in favor of the revision, it shall be made by a Constitutional Convention elected in the manner provided by law. Every revision of this Constitution shall be submitted to the qualified electors at a special referendum for ratification or rejection by a majority of the votes cast at the referendum.

Section 3. No amendment to this Constitution shall alter the republican form of government established by it or abolish its bill of rights.*
