The Texas Supreme Court ruled on September 11, 2026, against Galveston County’s plan to change its election precinct lines in the middle of an ongoing election cycle. This decision affects voters in Galveston County, ensuring that the precinct boundaries used for the March 2026 primary election will remain in place for the upcoming November general election. The ruling emphasizes the importance of maintaining consistent electoral boundaries to uphold the integrity of the election process.

The case, docketed as 26-0916, arose when Galveston County’s commissioners court decided to implement a new precinct map shortly after the March primary election, intending to use it for the general election. This plan raised concerns among local voters, who argued that changing precinct lines mid-election would create confusion and undermine the electoral process.

Background

The parties involved in this case include the Honorable Derreck Rose, Wilma Green, and Diane Merchant, who are all registered voters in Galveston County. They filed a petition for writ of mandamus, seeking to prevent the county from implementing the new precinct map for the November general election. The voters contended that the county's decision violated the Texas Election Code, which implies that precinct boundaries should remain unchanged between the primary and general elections.

Galveston County had held its primary election in March 2026 using precinct boundaries established in previous years. However, on June 29, 2026, the county adopted a new precinct map that it intended to use for the general election, despite the fact that the primary election had already taken place. The voters argued that this decision was not supported by any valid legal authority and would disrupt the orderly conduct of elections.

The Ruling

The Texas Supreme Court unanimously ruled in favor of the voters, stating that Galveston County did not have the authority to change precinct lines during an ongoing election. The court emphasized, "A commissioners court’s general power to redraw precinct lines 'from time to time' does not include the power to change the lines applicable to an election after the election has begun." This ruling effectively blocks the county's plan to implement the new precinct map for the general election.

The court highlighted that the Election Code requires consistency in precinct boundaries throughout the election process. The justices noted that allowing the county to change precinct lines mid-election would create significant irregularities, potentially disenfranchising voters and complicating the electoral process. The court ordered the county to conduct the general election using the same precinct maps that were in effect during the primary election.

Impact

This ruling has significant implications for voters in Galveston County and potentially sets a precedent for how mid-election changes to precinct lines are handled in Texas. By reinforcing the principle that precinct boundaries should remain stable during an election cycle, the court aims to protect the integrity of the electoral process. This decision ensures that voters will be able to cast their ballots for candidates they selected during the primary election, maintaining a consistent electoral experience.

The ruling also serves as a reminder to local governments about the limitations of their authority concerning election procedures. It clarifies that while counties may have the power to redraw precinct lines, they must do so in accordance with established election laws and cannot make arbitrary changes that disrupt the electoral process.

What's Next

Galveston County must comply with the court's ruling and use the precinct maps from the March 2026 primary election for the general election. Details on whether the county plans to appeal the decision were not available in the court filing. This case highlights the ongoing legal discussions surrounding electoral processes and the importance of maintaining clear and consistent guidelines for elections in Texas.
