LOS ANGELES (TNND) — A federal appeals court ruled Friday to uphold a lower court's temporary order blocking President Donald Trump's administration from its "roving patrols" amid its large-scale immigration crackdown in Los Angeles.

A panel of judges at the Ninth U.S. Circuit Court of Appeals held the hearing after the federal government asked the court to overturn the temporary restraining order issued by Judge Maame E. Frimpong on July 11.

Immigrant advocacy groups filed suit last month, accusing Trump’s administration of systematically targeting brown-skinned people in Southern California during the administration's crackdown on illegal immigration. The lawsuit included three detained immigrants and two U.S. citizens as plaintiffs.

Frimpong's order prohibited federal agents from arresting people based on race or ethnicity, the fact that they speak Spanish or have an accent, their presence in a location, or their occupation.

“The factors that defendants appear to rely on for reasonable suspicion seem no more indicative of illegal presence in the country than of legal presence — such as working at low-wage occupations such as car wash attendants and day laborers,” Judge Frimpong wrote. “That is insufficient and impermissible.”

Frimpong stated that the "roving patrols without reasonable suspicion violate the Fourth Amendment to the Constitution."

The Ninth U.S. Circuit Court of Appeals agreed and questioned the government's need to oppose an order preventing it from violating the Constitution.

"We agree with the district court that, in the context of the Central District of California, the four enumerated factors at issue — apparent race or ethnicity, speaking Spanish or speaking English with an accent, particular location, and type of work, even when considered together — describe only a broad profile and 'do not demonstrate reasonable suspicion for any particular stop,'" the judges wrote it in opinion.

A hearing for a preliminary injunction, which would be a more substantial court order as the lawsuit proceeds, is scheduled for September.

"The White House tried to experiment on Los Angeles. Their experiment failed," Mayor Karen Bass wrote on X. "Tonight, we’re sending a message to cities all across the country: Stand united and stand strong. Justice will prevail."

Earlier this month, the Pentagon ended the deployment of 2,000 National Guard troops in Los Angeles after they assisted in protecting property while immigration enforcement made arrests.

Roughly 4,000 National Guard soldiers and 700 Marines had been in the city since early June.

California Gov. Gavin Newsom sued the Trump administration for deploying the National Guard, but a federal appeals court ruled that Trump could maintain control.
