A group of Texas Republicans has lost one of two legal challenges brought in the hope of halting drive-through voting in Houston and having more than 120,000 votes thrown out.
In a brief order issued on Sunday, the Texas Supreme Court denied a request by conservative activist Steven Hotze and others for an order that drive-through voting violates Texas election law.
A nearly identical case brought by the same plaintiffs is pending in federal court. The judge assigned to that case has scheduled an emergency hearing for Monday morning.
"Our fight in federal court against this same effort continues," Marc Elias, a Democratic Party lawyer, wrote on Twitter.
A lawyer for Hotze did not immediately respond to a request for comment.
Democratic-leaning Harris County, home to about 4.7 million people, is the third most populous county in the United States. It currently has 10 drive-through polling sites, which are available to all voters.
Harris County Clerk Chris Hollins has called drive-through voting a safe alternative to in-person voting during the coronavirus pandemic.
Texas, the secon- largest U.S. state, is traditionally Republican, but polls show a close race between President Donald Trump and Democratic nominee Joe Biden with more than 9 million ballots already cast, eclipsing the state's total turnout from the 2016 presidential election.
Sunday's order came as little surprise after the state's supreme court on Oct. 22 denied a similar request to halt drive-through voting, in a lawsuit filed by the Republican parties of Texas and Harris County.
U.S. District Judge Andrew Hanen in Houston is due to hold an emergency hearing on Monday in the federal court action brought by Hotze and other plaintiffs, who include state Representative Steve Toth, a Republican.
They want Hanen to direct officials to halt drive-through voting and reject the roughly 127,000 ballots that have already been cast at 10 drive-through voting sites.
The request to void votes is "wholly unreasonable," Democratic groups, including the Democratic Congressional Campaign Committee, said on Friday in a motion asking to intervene in the case.
"Plaintiffs ask this Court to throw Texas's election into chaos by invalidating the votes of more than 100,000 eligible Texas voters who cast their ballots at drive-thru voting locations at the invitation of county officials and in reliance on the Texas Supreme Court's decision to allow drive-thru voting to proceed," the groups said.
