• The Trump administration seeks Supreme Court intervention to stop California from counting mail ballots tied to over 20,000 registered voters it alleges may be noncitizens.
  • Lower courts have repeatedly refused emergency relief, citing unreliable data and risks of disenfranchising eligible voters before the November 3 midterms.
  • The case tests federal authority over state election procedures and could set precedent for last-minute judicial intervention.

Administration Turns to High Court

The Trump administration has asked the U.S. Supreme Court to intervene in its lawsuit seeking to block California from counting certain mail-in ballots, according to people familiar with the matter. The move comes after lower courts twice denied emergency relief in the case, which involves more than 20,000 registered voters whom federal officials allege may be noncitizens.

The immediate issue is whether those ballots must be separated and withheld from counting until citizenship is verified—not whether California may count mail ballots generally. The administration’s request was filed late Monday, according to court records, and no justice has yet responded.

Legal Setbacks Mount

The case has moved quickly through the federal courts. On October 15, the Justice Department sued California and a Los Angeles County official, seeking to segregate ballots from people on a federal list of alleged “likely noncitizens” and withhold counting until citizenship could be established. A Ninth Circuit panel rejected an initial emergency request on October 26, 2–1, finding the administration had not given the district court an adequate opportunity to rule. Two days later, U.S. District Judge David Carter denied a temporary restraining order, warning that the requested intervention would “wreak havoc” on the election and could disenfranchise lawful voters.

The Ninth Circuit again denied emergency relief on October 30, this time considering the substance of the request. The majority emphasized uncertainty about the government’s list and the risk of disenfranchisement. “The government’s data appears to be riddled with errors,” the majority wrote, without naming the judges. The administration then signaled it would take its case to the Supreme Court.

Factual Disputes and Legal Questions

Noncitizens are prohibited from voting in federal elections. The dispute is over whether the administration has adequately identified ineligible voters and has legal authority to compel California to change its ballot-processing procedures at this stage. California says its existing safeguards are robust and the federal allegations rely on suspect data.

The roughly 20,000 figure describes registered voters on the government’s list—not 20,000 proven illegal votes. The Justice Department has not specified how many flagged individuals had actually submitted ballots, according to a person familiar with the matter. A request for intervention should not be confused with a ruling granting it.

At the heart of the case are competing views of federal versus state authority. Judge Carter and the appellate majority emphasized states’ constitutional role in administering elections. Carter also rejected the argument that counting ballots would necessarily impair federal prosecutions, noting that states are not required to assist federal criminal enforcement. The Ninth Circuit’s first ruling warned that an eleventh-hour order could interfere with California’s administration of an election already underway.

Political and Operational Stakes

The litigation comes immediately before elections in which Republicans are defending control of both chambers of Congress. It is part of an unusually direct Justice Department intervention in the voting process, alongside demands for voter records and related investigations. The administration has also sued roughly 30 states and the District of Columbia seeking unredacted voter rolls.

The most immediate stakeholders are the flagged voters, county election workers, candidates in close contests, and voters seeking confidence in the result. Eligible voters on the list could face delayed counting or exclusion if citizenship verification cannot be completed quickly. That potential harm was central to the courts’ decisions. Election officials face operational pressure because ballots become difficult or impossible to separate after processing. California’s lawyers acknowledged that a ballot cannot be separated once it has been processed.

The administration presents the intervention as a narrow election-integrity measure. California argues it risks disenfranchisement through uncertain database matching. These competing positions—not a judicial finding of 20,000 unlawful votes—define the debate.

The confrontation has also expanded beyond this lawsuit. A separate federal court order stopped the Justice Department from threatening California election officials with prosecution for defying its directives. Governor Gavin Newsom subsequently warned about possible attempts to seize ballots, while acknowledging that he did not know of any pending warrant request.

What’s Next

The decisive question is whether the Supreme Court issues an emergency order changing the lower courts’ refusal to require ballot segregation. Unless that refusal is displaced, the administration has not obtained the requested counting restriction. Even a temporary Supreme Court order would need to be read carefully: emergency relief is not necessarily a final determination that the flagged voters are ineligible.

The administration faces two clearly identified obstacles: the lower courts’ doubts about its evidence and their concern about disrupting an election already underway. Conversely, the dissent supplies its strongest immediate argument—that temporarily separating ballots could preserve the ability to verify eligibility without automatically cancelling votes. Those are the competing legal assessments supported by the record, rather than a reliable prediction of the Supreme Court’s vote.

A spokesperson for the Justice Department declined to comment. The Supreme Court’s public information office did not respond to a request for comment. California’s attorney general’s office did not immediately return a message seeking comment.
