The Trump administration on Thursday asked the U.S. Supreme Court to lift a lower court’s order that blocked immigration stops in Southern California, which a federal judge deemed indiscriminate and unconstitutional.

The emergency appeal follows a refusal by the Ninth Circuit Court of Appeals to dissolve the temporary restraining order. That order was issued by U.S. District Judge Maame E. Frimpong, who cited a “mountain of evidence” suggesting that the federal government’s immigration enforcement tactics in the region violated constitutional protections against unreasonable searches and seizures.

In its filing, the administration argued that Judge Frimpong’s order poses a significant barrier to enforcing federal immigration laws. The Justice Department contends that the decision unjustly restricts the ability of federal agents to carry out lawful enforcement operations.

The case now moves to the high court, where justices will decide whether to grant emergency relief pending further litigation.
