Texas Republicans have filed suit in the US District Court for the Southern District of Texas, seeking emergency and permanent injunctive relief against Harris County, Texas and the county clerk for allegedly violating federal and state laws by permitting curbside voting.

This is not the first attempt to seek a court order halting curbside voting in Harris County. A similar suit filed by Republicans was rejected by a Texas appeals court mid-October. In that action, a three-judge panel on the Fourteenth Court of Appeals wrote in their ruling that “the election is currently in progress and the relators delayed filing this mandamus until over a month after learning of the actions of the Harris County Clerk’s Office.”

This lawsuit filed Thursday in federal court, also targets Harris County’s drive-thru voting. The lawsuit requests that the court invalidate more than 117,000 votes.

Harris County is the most populated county in Texas and the third most populated in the country. At the core of this suit’s argument is that the county is discriminating against those who cannot utilize drive-thru voting. Citing the fact that this is the only county in Texas permitting drive-thru voting, the action alleges that this is a violation of the Equal Protection Clause of the Fourteenth Amendment to the US Constitution.
