HJR 123 proposes a constitutional amendment to establish an independent redistricting commission responsible for drawing district boundaries for the United States House of Representatives, the Texas Senate, and the Texas House of Representatives. The resolution creates Article XVIII of the Texas Constitution to outline the composition, appointment process, and operational procedures of the commission. It mandates transparency, public input, and nonpartisan criteria for drawing district lines while removing redistricting authority from the legislature. The amendment would repeal existing redistricting provisions under Article III and revise judicial district reapportionment rules. The proposal will be presented to voters in the November 2025 election​.
