H.B. No. 4 proposes a comprehensive redefinition of the electoral districts for the election of members of the United States House of Representatives from Texas. The bill meticulously outlines the specific counties and tracts that comprise each district, ensuring clarity in the geographic boundaries for Districts 1 through 38. Notably, it establishes that these new districts will be utilized for the elections starting in 2026 and includes a provision to address any inadvertent omissions of geographic areas by allowing courts to include them in the appropriate district based on legislative intent, referencing the case of Smith v. Patterson.

Additionally, the bill repeals all previous enactments or orders related to congressional districts in Texas, including Chapter 7 (S.B. 6) from the 87th Legislature's 3rd Called Session. It emphasizes that the new district configurations will not impact the membership or congressional districts of the 119th Congress. The bill is designed to ensure accurate representation and facilitate the electoral process, with its immediate effect contingent upon a two-thirds vote from both houses of the legislature.
