Los Angeles – In a move that directly affects immigration enforcement across Los Angeles, Orange, Riverside, San Bernardino, Ventura, Santa Barbara and San Luis Obispo counties, U.S. District Judge Maame Ewusi‑Mensah Frimpong issued a preliminary injunction on Sept. 2 that bars warrantless civil arrests unless agents can demonstrate a likelihood of escape.
What the order requires
Judge Frimpong wrote that the government must consider the “totality of the circumstances known to the agent or officer” when deciding whether an illegal immigrant poses a flight risk. The order also mandates that officers produce written documentation of the probable‑cause analysis before a warrant can be obtained. Simply noting a person’s unlawful status is no longer sufficient.
Background of the lawsuit
The case was filed last fall by the American Civil Liberties Union of Southern California, Public Counsel, and several local immigrant‑advocacy groups. Plaintiffs argued that, during a recent surge of immigration enforcement, officers frequently made arrests without any written assessment of flight risk, violating statutory requirements.
Federal attorney Daniel Mummolo told the court that there is no statutory mandate to document the risk assessment, and that practices vary among agents. He cited a January 2026 memo from former acting ICE director Todd Lyons that permits officers to make an “on‑the‑spot” determination of escape likelihood.
Judge’s findings
Judge Frimpong rejected the government’s request to stay the order while it appeals, stating that without proper documentation the agency cannot prove that any arrest was lawful. She highlighted video evidence showing an alleged “running away” incident was, in fact, a calm walk and text‑message exchange before agents began questioning.
According to the judge, a “wealth of record evidence” – including agency directives, arrest narratives, depositions and video – demonstrates that the current policy often bases escape‑risk assessments solely on unlawful status or unverified assertions, or skips the assessment entirely.
Administration response
The Department of Homeland Security has not yet commented on the ruling. However, the Trump administration has repeatedly emphasized the importance of robust immigration enforcement to protect American communities and uphold the rule of law. Administration officials have argued that strong enforcement deters illegal entry and safeguards public safety, and they are likely to seek clarification or modification of the order through the appellate process.
Impact on local communities
Advocates like Mayra Joachin of the ACLU of Southern California welcomed the decision, saying it should halt “hundreds – if not more – of unlawful arrests” throughout the region. The order now requires immigration officers to provide a clear, documented justification before depriving an individual of liberty, a step that many local faith‑based and family‑focused groups view as a protection of constitutional rights.
Law enforcement agencies in other districts – Portland, Colorado, Washington, D.C., and the Eastern District of California – have already issued similar restrictions, signaling a broader judicial trend toward tighter oversight of warrantless immigration arrests.
What’s next?
The government is expected to appeal the injunction, arguing that the requirement could impede timely enforcement and strain resources. Meanwhile, local officials and community leaders will monitor compliance to ensure that any future arrests meet the court‑mandated documentation standards.
