Court shuts down GOP-backed Arizona voter purge lawsuit

A federal appeals court delivered a win for voters Tuesday, rejecting a Republican-backed lawsuit that sought to force Arizona to aggressively purge its voter rolls based on unproven claims of widespread voter fraud.

The Ninth Circuit Court of Appeals affirmed a lower court’s dismissal in a case brought by GOP activists who alleged — without concrete evidence — that Arizona’s voter rolls were so inflated they risked allowing ‘illegal’ votes to be cast. The court found those claims too speculative to even be heard.

At the heart of the case was a familiar argument in modern election denial lawsuits that the mere possibility of ineligible voters on registration rolls creates a risk of fraud and dilutes the votes of eligible voters.

But the court made clear that those hypothetical fears are not enough to justify federal intervention.

“Their injury is entirely hypothetical: Plaintiffs claim that including ineligible voters on the rolls ‘heightens the risk’ of ineligible ballots being cast and counted by offering ineligible voters ‘an opportunity’ to vote, ‘risking the dilution’ of plaintiffs’ ballots,’” the court wrote. “Plaintiffs may not ‘manufacture standing merely based on their fears of hypothetical future harm that is not certainly impending.’”

The court emphasized that federal courts require a real, concrete harm — not a chain of “what ifs.” In legal terms, that requirement is called “standing,” meaning a plaintiff must show they have actually been or will imminently be harmed.

“Such ‘conjectural allegations of potential injuries’ and ‘chains of hypothetical contingencies’ are insufficient to plead an actual or imminent injury,” the court added.

The lawsuit was filed in 2024 by Scott Mussi, the president of an anti-voting group, and election denier and Arizona Republican Party chair Gina Swoboda, against Arizona Secretary of State Adrian Fontes (D). 

The plaintiffs pointed to high voter registration rates as supposed evidence that the state was failing to maintain accurate rolls under federal law.

They asked the court to order Arizona to create and implement a more aggressive voter removal program.

But both the district court and now the Ninth Circuit rejected that theory, finding no evidence that any alleged irregularities had actually resulted in illegal votes — or harmed the plaintiffs in any way.

“Although plaintiffs allege that ‘known cases of voter fraud’ have occurred in Arizona, they do not allege that any of those cases were the result of inadequate list maintenance or that they affected the plaintiffs,” the court concluded.

Courts have consistently required plaintiffs to connect their claims to real-world harm — not broad concerns about statistical anomalies.

The ruling is part of a broader trend in which courts across the country have repeatedly rejected efforts to use the federal court to force large-scale voter purges based on speculative claims.

The dismissal leaves Arizona’s voter registration system intact and reinforces that federal courts are not venues for litigating abstract fears about elections to justify sweeping voter purges.
