A federal judge on Friday found that the Department of Homeland Security has been making stops and arrests in Los Angeles immigration raids without probable cause and ordered the department to stop detaining individuals based solely on race, spoken language or occupation.

US District Judge Maame Ewusi-Mensah Frimpong, an appointee of former President Joe Biden, ordered that DHS must develop guidance for officers to determine “reasonable suspicion” outside of the apparent race or ethnicity of a person, the language they speak or their accent, “presence at a particular location” such as a bus stop or “the type of work one does.”

Friday’s ruling comes after the ACLU of Southern California brought a case against the Trump administration last week on behalf of five people and immigration advocacy groups, alleging that DHS — which oversees Immigration and Customs Enforcement — has made unconstitutional arrests and prevented detainees’ access to attorneys.

The ruling is limited to the seven-county jurisdiction of the US Central District of California, which includes Los Angeles and surrounding areas.

Frimpong said in her ruling that the court needed to decide whether the plaintiffs could prove that the Trump administration “is indeed conducting roving patrols without reasonable suspicion and denying access to lawyers.”
