Judge Sets Aside DOJ Plan to Check Voter Rolls Against Citizenship Data

A federal judge set aside a Justice Department policy aimed at collecting statewide voter-registration lists and checking names against federal citizenship records. The October 9 ruling found that the department exceeded its authority and failed to adequately consider inaccurate matches that could affect eligible voters.

The decision limits this particular federal initiative ahead of the November midterms. It does not eliminate states’ existing responsibility to maintain their own voter rolls.

The DOJ Wanted Statewide Lists

The disputed policy contemplated obtaining unredacted voter-registration lists from states and comparing the names with federal citizenship data. The department also envisioned notifying states when a match suggested that a registered voter might be ineligible.

Common Cause and individual voters challenged the effort, arguing that sweeping collection and comparisons raised legal and privacy concerns. They also warned that errors in citizenship data could affect citizens who were properly registered.

The Court Identified Legal Limits

U.S. District Judge Sparkle L. Sooknanan held that the statutes cited by the department did not authorize the challenged policy. The court also found that the agency had inadequately considered documented risks of inaccurate information.

The opinion addressed problems under federal privacy and administrative laws and vacated the policy. The ruling applies to the federal program as presented, rather than all eligibility checks conducted under state law.

What the Ruling Means Before November

States retain their own legal duties over registration maintenance, subject to federal and state requirements. Any appeal or stay would need to be evaluated separately; the October 9 order set aside the DOJ policy described in the case.
