A Biden-appointed federal judge in the Northern District of California has issued a preliminary injunction blocking key aspects of the Department of Homeland Security’s efforts to investigate potential noncitizen voting under the Trump Administration’s Unlawful Voter Initiative and Surge Initiative Guidance.
U.S. District Judge Araceli Martínez-Olguín, who was born in Mexico, granted the injunction on October 21, 2026, in the case California Nurses Association et al. v. Markwayne Mullin et al.
The order temporarily bars DHS, ICE, USCIS, HSI, and related officials from conducting elections-related field operations and field interviews in nine states, California, Connecticut, Georgia, Missouri, Nevada, New York, Pennsylvania, Washington, and Wisconsin, when those operations involve or are likely to involve persons whom agents know, suspect, or should reasonably know or suspect are U.S. citizens.
It also restricts operations based wholly on TECS records generated from the Voter Eligibility Matching Policy against such persons.
The injunction remains in effect until November 3, 2026 (Election Day, when polls close), but is stayed until 5:00 p.m. on Friday, October 23, giving the administration time to seek appellate relief. Plaintiffs were ordered to post a nominal $100 bond.
According to the court’s own factual background, the Trump Administration has prioritized voter fraud enforcement. In June 2026, DHS General Counsel directed ICE to pursue stricter penalties, including deportation, against noncitizens believed to have improperly registered or voted, whether or not criminally convicted.
In August 2026, DHS launched the Unlawful Voter Initiative, directing USCIS to generate target lists for investigation related to improper voting and coordinate with HSI field offices for interrogations.
On August 31, the Surge Initiative Guidance directed HSI agents to prioritize field investigations questioning people about voter eligibility in the nine listed states.
Implementation involved what plaintiffs described as a Voter Eligibility Matching Policy (compiling and refining target lists from state/local data, commercial databases, and other sources via systems like iLab) and a Field Operations Policy (increased deployment for interviews and investigations, timed around registration and early voting).
The order notes that initial target list data was “voluminous and unreliable,” including tens of millions of records from independent sources of “questionable provenance,” official state voter rolls (or commercial versions for non-sharing states), and enrichment processes.
USCIS personnel were instructed to treat source data as presumptively valid, seek to exclude U.S. citizens, and complete rapid reviews (with Surge quotas of at least 40 suspected subject reviews and limits around 12 minutes per elimination using commercial databases).
Errors from similar names, incomplete records, outdated citizenship information, and clerical issues were acknowledged, and there is no comprehensive federal database of citizenship status for U.S. residents.
The policy specifically targeted naturalized citizens in some cases where data suggested voting before naturalization.
Plaintiffs, including the California Nurses Association and National Nurses United, the City and County of San Francisco, the County of Santa Clara, and Voto Latino Foundation, sued under the Voting Rights Act (Section 11(b) on intimidation of voters and those assisting/mobilizing voters), the constitutional right to vote, and the Administrative Procedure Act.
They alleged intimidation via armed agents, social media publicization of operations/arrests, and reliance on flawed data that swept in citizens.
Judge Martínez-Olguín found that CNA/NNU established associational standing for the VRA claim related to intimidation affecting voter assistance and mobilization (based on member declarations about fear leading some to stop attending campaign events or serving as poll monitors).
She concluded they were likely to succeed on the merits of that claim, citing objectively reasonable fear generated by the Surge, publicization of operations with armed officers, and data known to include citizens.
Other plaintiffs’ standing claims (proprietary interests for local governments; organizational standing for Voto Latino) were rejected at this stage.
APA claims and direct voter intimidation/constitutional claims were not reached on the merits due to standing or final agency action issues. The court set a nominal bond and sealed portions of the supplemental administrative record and related reply materials.
The order explicitly states that it does not find investigations into unlawful noncitizen voting themselves unlawful, nor does it prevent DHS from pursuing voter fraud by other lawful means. It focuses on operations that sweep in or intimidate citizens engaged in protected mobilization activities.
