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 redistricting computer system operated by the Texas Legislative Council under the designation PLANC2308. The bill also clarifies the definitions of geographic areas 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 the legislative intent and relevant evidence, including a reference to the case 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, without affecting the current congressional membership or districts for the 119th Congress. The bill will take effect immediately if it receives a two-thirds vote from both houses; otherwise, it will take effect 91 days after the legislative session concludes.
