Judge dismisses federal government’s lawsuit over Wisconsin voter records

The Department of Justice has sued 30 states for access to their voter data, and eight of those lawsuits have now been dismissed.

A federal judge on Thursday rejected the U.S. Justice Department’s demand for Wisconsin’s unredacted voter list, the latest defeat for President Donald Trump’s administration in its quest to obtain more information about voters around the country.

In his 10-page ruling, U.S. District Judge James D. Peterson said the department’s allegation that the Wisconsin Elections Commission violated the Civil Rights Act by not turning over the state’s voter roll “fails as a matter of law.”

The Department of Justice has requested voter rolls with unredacted information — including voters’ full birthdates, full or partial Social Security numbers, and driver’s license information — from at least 48 states, according to the Brennan Center for Justice. At least 15 states have provided or said they will provide the data, but most have not, prompting the department to file suit against 30 states plus Washington, D.C.

Federal judges have so far dismissed those lawsuits in seven other states, including Michigan, Oregon, California, Rhode Island, Massachusetts, and Arizona. The Department of Justice’s lawsuit against Maine was also dismissed on Thursday.

The department has so far appealed three of those dismissals, the ones in Michigan, Oregon, and California.

The Justice Department has said it is entitled to the voter rolls under federal law and needs the data to enforce requirements in federal statutes. Officials in both Republican- and Democratic-led states have pushed back on the Justice Department’s request for unredacted voter data, saying it could put voters at risk. They also say the department hasn’t provided enough information on how the data would be used.

The federal government requested Wisconsin’s unredacted voter rolls late last year, and the Wisconsin Elections Commission argued that state law explicitly bans election officials from disclosing information like driver’s license numbers to most people who aren’t election officials. That led to the lawsuit.

The Justice Department didn’t immediately respond to a request for comment.

“This ruling protects against federal intrusions into Wisconsin’s election system,” said ACLU of Wisconsin legal director Ryan Cox, adding that it “ensures private voter data is safe from abuse, and prevents the Trump administration from playing politics with our right to vote.”
