DOJ vs. Adrian Fontes, Arizona Voter Rolls Lawsuit Full Case Breakdown

“This article covers a concluded federal civil lawsuit. Information is based on official court records and verified reporting from AP, NBC News, The Hill, and the Arizona Attorney General’s office.”

U.S. Department of Justice vs. Adrian Fontes is a federal civil lawsuit in which the DOJ sued Arizona Secretary of State Adrian Fontes, demanding he hand over the state’s full voter registration database. U.S. District Judge Susan Brnovich dismissed the case with prejudice on April 29, 2026, ruling that Arizona’s statewide voter registration list is not a document the Attorney General has the legal right to request. The dismissal means the DOJ cannot refile this same claim against Arizona.

What Is the DOJ vs. Fontes Lawsuit About?

The DOJ asked the court to order Fontes to provide then-Attorney General Pam Bondi with a full electronic copy of Arizona’s voter registration list — including each registrant’s full name, date of birth, residential address, and either their driver’s license number, the last four digits of their Social Security number, or a unique identifier assigned under the Help America Vote Act of 2002.

The DOJ’s legal theory rested on the Civil Rights Act of 1960. The lawsuit alleged that Act imposes a “sweeping obligation on election officials” to retain and preserve election records and grants the Attorney General broad power to obtain those records. Fontes rejected that argument, saying the demand violated both state and federal privacy laws.

Fontes also argued in court filings that anyone who makes it onto Arizona’s voter rolls has already demonstrated United States citizenship under state law — making the federal request unnecessary even on its own stated terms. For readers who want more background on how federal election law intersects with state voter data rules.

Who Are the Parties?

Adrian Fontes is the elected Democratic Secretary of State of Arizona. His office manages the state’s official voter registration database, which according to the Arizona AG’s office covers the personal information of millions of registered Arizona voters. Fontes refused the DOJ’s request from the start, and his office was backed in court by Arizona Attorney General Kris Mayes.

The DOJ under Trump requested complete voter registration lists from the governments of at least 48 states and Washington, D.C., according to the Brennan Center for Justice, and sued 30 states and the District of Columbia for refusing to provide them. Arizona was one of those states that refused and got sued.

How Did the Lawsuit End?

Judge Brnovich — herself a Trump appointee — sided with Arizona and dismissed the case with prejudice, meaning it cannot be refiled. The court concluded that Arizona’s statewide voter registration list is not a document the Civil Rights Act of 1960 entitles the Attorney General to obtain.

Dismissed with prejudice means the case is permanently closed. The DOJ cannot fix its complaint and try again in the same court on the same legal theory. The ruling strikes at the core of the DOJ’s legal theory, finding that the Civil Rights Act provision at issue applies only to documents submitted by voters — such as registration forms — not statewide databases created and maintained by election officials.

Arizona Attorney General Kris Mayes and Secretary Fontes called the ruling a vindication, stating that the court was clear that Title III of the Civil Rights Act does not authorize this kind of demand, and noted it was the sixth federal court to reach the same conclusion.

What Does This Case Mean for Arizona Voters and Other States?

Judges have now rejected similar DOJ efforts to obtain sensitive voter information in California, Massachusetts, Michigan, Oregon, and Rhode Island — making this the sixth straight loss for the federal government in this nationwide push.

At least 13 states — including Alaska, Arkansas, Indiana, Louisiana, Mississippi, Nebraska, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, and Wyoming — have either provided or promised to provide their detailed voter registration lists to the DOJ. So the legal battle continues in other courtrooms across the country.

In March 2026, a DOJ attorney acknowledged in the Rhode Island case that voter registration data collected from states is being shared with the Department of Homeland Security to check citizenship status. That admission gave additional legal weight to Arizona’s argument that the demand went beyond election law compliance. To understand how similar voter data disputes have played out nationally.

Frequently Asked Questions

The U.S. Department of Justice filed suit against Arizona Secretary of State Adrian Fontes in January 2026.

Has the case been resolved?

 Yes. The judge dismissed the lawsuit with prejudice, ruling that amendment would be legally futile. The DOJ cannot refile this same claim against Arizona.
