Judge Blocks Warrantless Immigration Arrests in Southern California

A federal judge has issued a preliminary injunction preventing U.S. immigration officers from making warrantless arrests in Southern California unless they first determine the individual is likely to escape before obtaining a warrant. The ruling, signed by District Judge Maame Ewusi-Mensah Frimpong on Wednesday and granted earlier that week, applies across seven counties including Los Angeles, Orange, Riverside, San Bernardino, Ventura, Santa Barbara, and San Luis Obispo.

In the order, Frimpong stated that mere illegal presence within the United States is insufficient to justify a warrantless arrest. Instead, agents must assess the totality of circumstances regarding an individual's likelihood of fleeing before acting without a warrant. Additionally, the judge mandated that the government thoroughly document probable cause required for securing any subsequent warrant.

The lawsuit was filed by the American Civil Liberties Union of Southern California and other immigrant advocacy groups amid a surge in immigration enforcement activity. The court denied the Department of Homeland Security's request to delay or stay the order while they appeal, noting without such documentation arrests cannot be deemed proper.
