Supreme Court Denies Trump Admin Request to Block 20K California Ballots
The Supreme Court refused to block 20,000 California ballots flagged for noncitizen voting.
Why it matters: Legal teams and election officials should prepare for continued litigation amid federal-state election conflicts. This decision affects election compliance strategies in key states.
- Supreme Court declined to block segregation of over 20,000 California ballots on Nov. 2, 2026, as requested by the Trump administration.
- Lower courts, including a federal district court and the Ninth Circuit, had already rejected the ballot segregation efforts.
- UCLA Voting Rights Project found 42% of DOJ-flagged individuals are absent from California's voter rolls, and identified at least 22 U.S. citizens wrongly flagged.
- California argued DOJ's list is error-prone and segregating ballots risks disenfranchising eligible voters and disrupting elections.
On November 2, 2026, the U.S. Supreme Court declined to block a Trump administration effort to segregate over 20,000 California ballots flagged as potentially cast by noncitizens. The Court's order came without explanation and upheld prior rulings from a federal district judge and the Ninth Circuit Court of Appeals that denied the request.
The Department of Justice's list, which prompted the challenge, was analyzed by the UCLA Voting Rights Project. The UCLA team reported that 42% of the flagged individuals were not registered voters in California. They also identified at least 22 confirmed U.S. citizens mistakenly included on the DOJ's list. Additionally, approximately 7,500 naturalized citizens appeared to be wrongly categorized as noncitizens. This analysis indicates significant inaccuracies in the federal data used to challenge the ballots.
California election officials strongly opposed the DOJ request. They argued that the federal government's list contains errors and that forcing election officials to "segregate" these ballots—meaning set them aside pending investigation—could disenfranchise lawful voters and disrupt the vote-counting process. Noncitizen voting is historically rare in the United States, weakening the rationale for broad ballot separation.
This dispute reflects ongoing federal-state tensions over election administration and enforcement. By declining to intervene, the Supreme Court allows this legal standoff to continue, signaling protracted litigation likely ahead. Election law practitioners, compliance teams, and legal operations professionals should monitor developments carefully given the compliance and operational risks involved.

By the numbers:
- 20,000 ballots — flagged by DOJ for potential noncitizen voting in California
- 42% — of DOJ-flagged individuals not found on California's voter rolls (UCLA analysis)
- 22 — confirmed U.S. citizens wrongly flagged as noncitizens
Yes, but: The DOJ's flagged list contains notable errors according to independent analysis, raising concerns about overreach and voter disenfranchisement.
What's next: Further litigation is expected as California election officials and federal authorities contest the handling and verification of flagged ballots.
