The Louisiana Constitution, the state constitution of Louisiana, has been amended several times since its adoption in 1974. The process of amending the constitution is outlined in Article 13, which details the legislative process and the state constitutional convention. A simple majority vote (50% plus 1) is required for voters to approve constitutional amendments, and amendments can be referred to the ballot in odd-numbered and even-numbered years. The state legislature can refer constitutional amendments to the ballot, with a two-thirds vote required during one session of the Louisiana State Legislature for an amendment to be placed on the ballot. This process does not require the governor's signature.
