The legal action centers on Heap's use of the Systematic Alien Verification for Entitlements (SAVE) database, a tool recently overhauled by the Trump administration to detect noncitizens registered to vote. The database has been found to produce false positives, flagging U.S. citizens as noncitizens.
According to the lawsuit, Heap used SAVE to identify 207 voters he deemed likely noncitizens and forwarded information on them to the Maricopa County Attorney's Office (MCAO) earlier this year. Of those, 60 had cast ballots, and Heap moved those voters to a "non eligible" category, effectively canceling their registrations unless they provided documented proof of citizenship before the next election.
A review by MCAO found that only eight of the 60 were actually noncitizens, and no more than three ever voted in the same election. The Attorney General's Office made similar findings. Despite this, 25 of those 60 voters, whose citizenship was verified by both MCAO and the AG's Office, remain unable to vote.
"Absent this Court's prompt intervention, the twenty-five Affected Voters will be illegally denied their right to vote in the November 3, 2026 general election," the two Democrats wrote in the lawsuit. "The Recorder has refused to voluntarily undertake his statutory duty, so must be ordered to do so."
Heap's office called the lawsuit "partisan political theater" and claimed that MCAO had advised his office to cancel the registrations. The Recorder's Office said it placed the voters in a suspended registration status requiring proof of citizenship "to give them every possible opportunity to vote a full ballot."
Maricopa County Attorney Rachel Mitchell refuted Heap's characterization. "The Maricopa County Attorney's Office follows the law," Mitchell said in a press release. "Therefore, contrary to the Maricopa County Recorder's October 22nd press release, we never advised the Recorder to cancel the registration of voters." Mitchell added that Arizona law does not allow for any sort of suspended category while under investigation and does not permit the County Attorney to stand in for the Recorder in gathering proof of citizenship.
The lawsuit argues that Heap violated state law by canceling registrations before voters were proven to be noncitizens and that his office has not responded to letters and requests from the AG. The plaintiffs are asking the court to order Heap to reinstate the voters, prevent him from requiring them to vote provisional ballots, and ensure that any provisional ballots cast by these voters are not rejected based on the "not eligible" status.
A hearing is scheduled for Friday morning.
