The proposed joint resolution seeks to amend the Texas Constitution by adding Section 28A to Article III, which would impose restrictions on the timing of legislative actions regarding the apportionment or modification of districts for both the Texas Legislature and the United States House of Representatives. Specifically, it stipulates that the legislature can only enact such changes during the designated timeframes: when required by the federal decennial census or within a specified period following the census release. This aims to create a more structured and predictable process for redistricting, thereby reducing the potential for partisan manipulation.

Additionally, the resolution includes a provision that allows the legislature to enact modifications if a court or governmental agency determines that existing districts are invalid or if such actions prevent elections from occurring in those districts. However, it also restricts the legislature from making changes during the period when the Legislative Redistricting Board has exclusive jurisdiction over those districts. The proposed amendment will be presented to voters in an election scheduled for November 3, 2026, allowing the public to decide on the implementation of these new limitations.
