Galveston County voters have filed an emergency petition for a writ of mandamus asking the Texas Supreme Court to block the county from implementing new precinct maps for the November election. In June, the Galveston County Commissioners Court adopted a 2026 map that established new precinct boundaries for county commissioners, justices of the peace, and constables. The latest legal challenge follows the 2022 Petteway lawsuit, which challenged Galveston County’s 2021 redistricting map and sought to redraw four county commissioners’ precincts. In 2026, the Commissioners Court adopted a new map combining the precinct boundaries for county commissioners, justices of the peace, and constables. Joseph Nixon, an attorney representing Galveston County, told the Daily Signal that the new map effectively mooted the remaining claims in the Petteway case.
