The bill, titled H.B. No. 4, proposes new congressional district boundaries for the election of members of the United States House of Representatives from Texas. It establishes that one member will be elected from each district as described in Article II, which references the districts outlined by PLANC2308 on the Texas Legislative Council's redistricting computer system. The bill also defines key geographic terms such as "tract," "block group," and "block" 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, guided by legislative intent and relevant evidence, specifically citing the case of Smith v. Patterson. It repeals all previous laws and orders related to congressional districts in Texas, including Chapter 7 from the 87th Legislature, and specifies that the new districts will be applicable for elections starting in 2026, while not affecting the current congressional membership or districts for the 119th Congress. The bill will take effect immediately if it receives a two-thirds majority vote in both houses; otherwise, it will take effect 91 days after the legislative session ends.
