ACLU and Common Cause Sue DOJ to Block National Voter Surveillance Database as Draft Emergency Election EO Circulates

The ACLU and Common Cause filed suit in federal court (Common Cause v. U.S. Department of Justice, No. 1:26-cv-01352-SLS, D.D.C.) on April 21, 2026 to block DOJ’s construction of what would be the first centralized national voter database in U.S. history. DOJ had demanded unredacted voter registration data — including partial Social Security numbers and driver’s license numbers — from all 50 states and D.C.; multiple states refused, and DOJ sued them in response (documented separately in 2026-04-06–doj-voter-data-campaign-reaches-31-suits-30-states-dc). The plaintiffs argue the database is unconstitutional and designed to enable a national voter-purge and surveillance operation ahead of the 2026 midterms. Reported the same week: a draft emergency executive order, confirmed by Democracy Docket and ABC News, that would declare a national emergency based on debunked 2020 election-fraud claims and ban mail-in ballots nationwide — evidence the voter-database demand was one component of a broader pre-midterm election-control strategy rather than a standalone data request.

The database the suit targets is now cross-referenced against SAVE, an immigration-verification system with a documented history of false positives, creating substantial risk of mass wrongful purges of eligible voters. The threat is time-critical: the National Voter Registration Act’s 90-day blackout on systematic roll purges before a federal election begins August 5, 2026, ahead of the November midterms — while Republicans simultaneously push the Supreme Court to gut that same blackout protection via an Arizona case (RNC v. Mi Familia Vota) that, per OPB, is “not expected until next year.”

This is the origin point of a litigation track the corpus tracks through its later procedural stages: Common Cause moved for partial summary judgment on May 19 (2026-05-19–common-cause-partial-summary-judgment-doj-national-voter-database). The draft emergency EO reported alongside this filing did not surface again in the corpus’s DOJ voter-database coverage as of this entry — its status is an open lead.

Corrected 2026-10-01: merged in the duplicate entry 2026-07-15--aclu-sues-doj-national-voter-database-nvra-blackout-deadline, which turned out to cover this same lawsuit — same plaintiffs (Common Cause, ACLU, Protect Democracy), same ACLU press release URL — under a wrong date (2026-07-15) and framed it as a second, later suit (“the ACLU filed a second suit in July”); it was not. Merged in that entry’s sourced NVRA-blackout and Arizona-SCOTUS-case detail above, with its two unique sources (Campaign Legal Center, OPB); the 07-15 file has been deleted and its id recorded as previous_ids so /event/2026-07-15--.../ still resolves (redirect). Also corrected this entry’s own ACLU source date from 2026-04-24 to 2026-04-21 and the body’s filing date to April 21 — the press release itself is dated and datelined April 21, 2026 (“Today, Common Cause and four individual members sued…”), not April 24. This entry’s id/filename (2026-04-24) were left as-is per Mark’s 2026-10-01 instruction not to rename the surviving entry in a merge.
