Louisiana Constitution of 1974 Art. XIII, § 1. Amendments

(B) Form of Proposal. A proposed amendment shall have a title containing a brief summary of the changes proposed; shall be confined to one object; and shall set forth the entire article, or the sections or other subdivisions thereof, as proposed to be revised or only the article, sections, or other subdivisions proposed to be added. However, the legislature may propose, as one amendment, a revision of an entire article of this constitution which may contain multiple objects or changes. A section or other subdivision may be repealed by reference. When more than one amendment is submitted at the same election, each shall be submitted so as to enable the electors to vote on them separately.

(C) Ratification. If a majority of the electors voting on the proposed amendment approve it, the governor shall proclaim its adoption, and it shall become part of this constitution, effective twenty days after the proclamation, unless the amendment provides otherwise. A proposed amendment directly affecting not more than five parishes or areas within not more than five parishes shall become part of this constitution only when approved by a majority of the electors voting thereon in the state and also a majority of the electors voting thereon in each affected parish. However, a proposed amendment directly affecting not more than five municipalities, and only such municipalities, shall become part of this constitution only when approved by a majority of the electors voting thereon in the state and also a majority of the electors voting thereon in each such municipality.
