The ACLU, ACLU of Northern California, and ACLU of Southern California have filed a motion to intervene as Defendants in a suit brought by the Department of Justice against the California Secretary of State, who refused to turn over voter file information except as required by law. The motion to intervene was filed on behalf of the League of Women Voters of California. Concerns over unsubstantiated mass voter challenges and misuse of sensitive personal information have heightened the concerns of the League, who through their voter registration work, add people’s information to the voter roll, and who has worked to support the passage of laws that protect voter privacy.

If intervention is granted, the civil rights groups will seek to prevent the federal government from forcing California to turn over the entirety of its voter registration database and to protect sensitive data within the voter rolls.
