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, the resolution stipulates that the legislature can only enact or modify these districts during designated times: when the legislature is required to make apportionments following the federal decennial census or within a specified period after the census is released. This aims to create a more structured and predictable process for redistricting.

Additionally, the resolution includes provisions that allow the legislature to act outside these timeframes if a court or governmental agency determines that existing districts are invalid or if such a ruling prevents elections from occurring in those districts. However, it also specifies that the legislature cannot modify districts while the Legislative Redistricting Board has exclusive jurisdiction over them. The proposed amendment is set to be presented to voters in an election scheduled for November 3, 2026, allowing the public to decide on the implementation of these restrictions.
