Voting and civil rights groups sued Alaska elections officials on April 22, alleging that their sharing of the state’s full voter registration list with the U.S. Department of Justice violates the state constitution.

Alaska is one of at least 12 states that has provided or said it would provide detailed information about its voters — including date of birth, driver’s license number or partial Social Security number — to the Trump administration, according to the Brennan Center for Justice, a nonpartisan, nonprofit law and policy organization.

Alaska — and also Texas — signed agreements when they shared voter data in which the Justice Department outlined plans for its own analysis of voter files, its intent to flag voter list issues and directions for removing voters deemed ineligible.

Several other states provided the data but refused to sign those agreements.

The Justice Department has embarked on a wide-ranging effort to obtain detailed voter data from every state. Some elections officials have expressed concern the information being sought could be used by the Trump administration to search for possible noncitizens.

The Alaska lawsuit was filed in state court against state Division of Elections officials by the League of Women Voters of Alaska and Alaska Black Caucus. It alleges that handing over personal data on the voter list violates the right to privacy under the state constitution.

It also says the memorandum of understanding violates due process by allowing the Justice Department to flag voters for removal “without any apparent notice or process for impacted voters to challenge those decisions.”

Sam Curtis, a spokesperson with the state Department of Law, said by email that the department has previously explained in public hearings that state law “expressly permits the sharing of this information for authorized governmental purposes. That statute is on the books, and we will defend it.”

The plaintiffs are represented by the American Civil Liberties Union of Alaska, ACLU Voting Rights Project and the Electronic Privacy Information Center.

The Justice Department has sued at least 30 states and the District of Columbia to try to force the release of the data, according to a tally by the Brennan Center. Judges have rejected those efforts in California, Massachusetts, Michigan, Oregon and most recently, Rhode Island.

In the Rhode Island case, Justice Department attorneys acknowledged the department was seeking unredacted voter information so it could be shared with the Department of Homeland Security to check citizenship status.

In addition to the state court lawsuit in Alaska, at least four federal lawsuits have been filed around the U.S. seeking to stop the Justice Department from collecting information from unredacted voter registration files or to prevent states from taking steps to cancel or suspend people’s voter registrations based on the federal project.

The plaintiffs in the Alaska lawsuit are asking a judge to void the agreement and require the elections division to make “reasonable efforts” to ensure the immediate destruction by the Justice Department of any hard copies and electronic versions of the list that was shared.
