U.S. District Judge Charles Breyer put off issuing any additional rulings and instead asked for briefings from both sides by noon Monday on whether the Posse Comitatus Act, which prohibits troops from conducting civilian law enforcement on U.S. soil, is being violated in Los Angeles.

The hearing happened the day after the 9th Circuit appellate panel allowed the president to keep control of National Guard troops he deployed in response to protests over immigration raids.

California Gov. Gavin Newsom said in his complaint that “violation of the Posse Comitatus Act is imminent, if not already underway” but Breyer last week postponed considering that allegation.
