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.
The lawsuit came after the Texas Supreme Court, one of the most conservative state courts in the United States, rejected similar bids to halt drive-through voting in Harris County.
The plaintiffs ask the court to “reject any votes it finds were cast in violation of the Texas Election Code” and “requir[e] all memory cards from the 10 drive-thru voting locations be secured and not entered or downloaded into the Tally machine until this Court issues an order on this Complaint.”
Judge Hanen was appointed by President George W. Bush, a Republican.
The request 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.
Michael Morley, a professor of election law at Florida State University, called the lawsuit meritless and said it proposes an “extreme remedy.”
“I think the county has a strong legal basis under state law for implementing these voting alternatives during a pandemic,” Prof Morley said. “Even if the court disagreed, however, a remedy would most likely be purely prospective - prohibiting continued use of these mechanisms while still counting votes already cast.”
Texas, the second-largest US state, is a traditionally Republican state, but polls show President Donald Trump and Democratic nominee Joe Biden close, with more than nine million ballots already cast, eclipsing total turnout from 2016.
