A Trump-appointed federal judge in Phoenix dismissed the Justice Department’s lawsuit against Arizona’s voter rolls Tuesday, with prejudice. The ruling came down on April 28. It was the sixth time a federal court has rejected the DOJ’s nationwide push for unredacted state voter data, Brennan Center litigation tracking confirms. Arizona joins Massachusetts, California, Michigan, Oregon, and Rhode Island. The Department has yet to win a single case.
The headline is the ruling. The story is what Arizona did before any judge saw the case.
U.S. District Judge Susan Brnovich, an appointee of President Trump, wrote that Arizona’s voter list is “not a document subject to request by the Attorney General” under federal law, Votebeat reported. Amendment of the suit, she ruled, would be “legally futile.” The dismissal forecloses DOJ’s ability to refile in Arizona, the Associated Press confirmed. The Department has demanded full unredacted voter rolls from forty-four states and the District of Columbia since May 2025, per Brennan Center analysis, and has filed roughly thirty lawsuits against states that refused. Thirteen states handed their data over without litigation. The cases against the holdouts have been a clean sweep for the states.
Arizona’s four-move refusal
Arizona’s refusal ran in four moves before Brnovich opened the file. Secretary of State Adrian Fontes formally declined the DOJ request, citing federal preemption limits and Arizona’s confidentiality protections on voter data, including driver’s license numbers and partial Social Security numbers. Attorney General Kris Mayes co-signed a public legal opinion supporting the refusal, converting Fontes’s individual decision into a state legal posture rather than an officeholder’s preference. The two of them then wrote a joint letter to all fifteen county recorders telling them the federal demand “violates both federal and state law” and instructing local refusal. The letter pre-empted a maneuver federal enforcement actions sometimes try, bypassing state offices and going directly to counties. Brnovich’s ruling validated each move at every level. A judge ruling against the same administration that nominated her, on a plain-text reading of the federal statute, is the part that travels well across the political map.
The mechanics do not care which party signs the demand letter. The same procedural template would apply against a Democratic administration’s DOJ. The pattern is the same federalism dynamic Laterstack flagged earlier this year on AI law, when Arizona’s state-level AI protections were targeted by a federal preemption framework. The fight has moved from state AI bills to state voter rolls. The procedural defense looks identical.
What the federal interest looks like
DOJ’s case is not frivolous. Federal law authorizes the Attorney General to enforce both the National Voter Registration Act and the Help America Vote Act. The Department’s stated purpose has been list-maintenance compliance, the argument that without unredacted access it cannot audit how states manage their rolls. A California federal court rejected that framing last year, writing per Brennan Center reporting that “representations made by the DOJ elsewhere paint a starkly different picture that this Court cannot ignore.” The Cato Institute, writing from a federalism perspective, has argued that recent federal voting-data moves flunk the basic civics test on state authority over election administration. Both flanks of the argument exist on the public record. Brnovich rejected the statutory hook on which the audit-access argument rested, but the underlying federal interest in clean rolls is real, and a different fact pattern with a different statute could land somewhere else. State officials who refuse the current demands are not refusing federal oversight in principle. They are refusing this specific demand on this specific statute.
The DOGE-SSA dimension
A second story is unfolding alongside the Arizona ruling. Records first reported on April 29 by Democracy Docket reporter Yunior Rivas show personnel inside the Department of Government Efficiency signed a Voter Data Agreement with an outside political group on March 24, 2025. Democracy Forward, the legal nonprofit run by President and CEO Skye Perryman, obtained the records through public-records requests and ongoing litigation. The advocacy group had already acquired state voter rolls and wanted Social Security Administration analysis to support efforts to challenge election results in certain states. The agreement was not reviewed through SSA’s standard data-exchange procedures. DOGE team members shared data through unapproved third-party servers including Cloudflare between March 7 and March 17, 2025. SSA did not learn about the agreement until a separate review in November 2025. The disclosed records include Hatch Act referrals. A federal appeals court called the conduct “alarming.” A district court has now greenlit discovery, which means more documents are coming.
Why Laterstack will not name the redacted party
The names of the outside political group and most government officials in the disclosed records are redacted in the underlying filings. Democracy Docket has analyzed several candidates, including True the Vote, an organization that has publicly pursued voter-roll analysis for years. Laterstack will not name a redacted party without primary-source confirmation. Groups like True the Vote and similar entities have publicly pursued this kind of work, but the redaction itself is the story until the document trail closes the question.

The federalism principle
Arizona’s four-move playbook is the procedural defense against precisely the kind of arrangement the DOGE-SSA disclosure describes. State officials who require federal data demands to identify themselves, follow statute, and reach the right office through the right channel are not blocking law enforcement. They are insisting that the demand show its work.
This is a federalism story before it is a partisan one. Should any executive branch be able to share Social Security data with an unnamed organization to analyze voter rolls? That is the question that survives the next election.
What we are watching
Discovery in the Democracy Forward case is greenlit. The next batch of documents will land on the public docket in the coming weeks. Whichever states are next on the DOJ’s litigation list, including Washington, where the DOJ suit was allowed to proceed earlier this month, have Brnovich’s reasoning available to them and Arizona’s full four-move sequence to copy. The same federalism logic that drove forty-five states to introduce more than 1,500 AI bills before the federal framework arrived is the logic at work in the voter-data fight: a structural preference for state-level authority over centralized federal overrides, regardless of which party is in power.
This is a federalism story before it is a partisan one. The state-refusal playbook works regardless of which party controls the federal request. Coverage of this beat will hold to one rule: a federal data demand that bypasses normal procurement and oversight deserves the same scrutiny when it comes from any administration, and a state secretary of state defending the public’s data against that demand deserves the same coverage regardless of party affiliation.
Frequently Asked Questions
What did Judge Brnovich rule on April 28, 2026?
U.S. District Judge Susan Brnovich, a Trump appointee, dismissed the Department of Justice’s lawsuit against Arizona Secretary of State Adrian Fontes with prejudice. She ruled that Arizona’s voter list is “not a document subject to request by the Attorney General” under federal law, and wrote that amendment of the suit would be “legally futile.” The dismissal forecloses DOJ’s ability to refile in Arizona.
How many states has the Department of Justice lost in voter-roll litigation?
Six. Arizona joins Massachusetts, California, Michigan, Oregon, and Rhode Island as states where federal judges have ruled against the Justice Department on demands for unredacted voter rolls. The DOJ has filed roughly thirty such suits since the start of 2025 and has yet to win a single case, per Brennan Center tracking.
What is the four-move state-level playbook Arizona used?
Step one: the Secretary of State formally refuses the federal data demand. Step two: the Attorney General co-signs a public legal opinion supporting the refusal. Step three: the two offices write a joint letter to all county recorders instructing local refusal. Step four: the court confirms. Arizona executed all four moves before Judge Brnovich’s ruling validated the refusal at every level.
What is the DOGE / SSA Voter Data Agreement?
Records first reported on April 29, 2026 by Democracy Docket reporter Yunior Rivas show personnel inside the Department of Government Efficiency signed a Voter Data Agreement with an outside political group on March 24, 2025. The agreement was not reviewed through Social Security Administration’s standard data-exchange procedures. DOGE team members shared data through unapproved third-party servers including Cloudflare. A federal appeals court called the conduct “alarming” and a district court has greenlit discovery.
Will Laterstack name the redacted political group from the DOGE / SSA records?
No, not without primary-source confirmation. Democracy Docket has analyzed several candidates including True the Vote, but Laterstack will not name a redacted party without a verified document trail. The redaction itself is the story until discovery closes the question.
What states complied with the DOJ voter-roll demands without a fight?
Thirteen states handed their voter data over without litigation: Alaska, Arkansas, Indiana, Louisiana, Mississippi, Nebraska, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, and Wyoming. Source: Brennan Center analysis.
