The bill, titled H.B. No. 4, proposes new congressional district compositions for the election of members of the United States House of Representatives from Texas. It establishes that members will be elected from districts as described by PLANC2308 on the Texas Legislative Council's redistricting computer system. The bill specifies that one member will be elected from each district created by this Act and defines relevant geographic terms based on the 2020 Census data.

Additionally, the bill includes a provision that allows for the inclusion of any erroneously omitted geographic areas into the appropriate districts, referencing the Supreme Court of Texas case Smith v. Patterson for guidance. It repeals all previous laws and orders related to congressional districts in Texas, including Chapter 7 from the 87th Legislature, and states that the new districts will be applicable for elections starting in 2026, while not affecting the current congressional membership. The bill will take effect immediately if it receives a two-thirds majority vote; otherwise, it will take effect 91 days after the legislative session concludes.
