Senate Joint Resolution No. 63, proposed by Senator Middleton, seeks to amend the Texas Constitution by changing references to the "Gulf of Mexico" to "Gulf of America." This resolution includes amendments to several sections of the Texas Constitution, specifically addressing definitions related to public beaches, tax relief for mobile marine drilling equipment, and the authority of counties bordering the Gulf to regulate public beach activities. The proposed changes aim to clarify terminology and ensure that the rights of the public and local governments are maintained regarding the use and management of coastal resources.

The resolution has undergone committee review and was reported favorably with a substitute on April 14, 2025. If approved, the constitutional amendment will be presented to voters in a referendum scheduled for November 4, 2025. The ballot will allow voters to express their support or opposition to the change in terminology regarding the Gulf, reflecting a significant shift in how this body of water is referenced in state law.
