Federal Appeals Court Blocks California Law Requiring Federal Agents to Wear Identification

A federal appeals court issued an order Wednesday blocking a California law requiring federal immigration agents to wear identification, another blow to the state’s attempts to limit the Trump administration’s aggressive enforcement tactics.

The Trump administration argued that it would threaten the safety of officers who are facing harassment, doxing, and violence and that it violated the constitution because the state was directly seeking to regulate the federal government.

A three-judge panel of the 9th U.S. Circuit Court of Appeals issued an injunction pending appeal. It had earlier blocked the law from taking effect.

The appeals court agreed unanimously, saying the law “attempts to directly regulate the United States in its performance of governmental functions,” in an opinion written by Judge Mark J. Bennett. The panel was composed of two Trump appointees, Bennett and Daniel P. Collins, and Obama appointee Jacqueline H. Nguyen.

California lawyers argued that the law applied equally to all law enforcement officers without discriminating against the U.S. government, and that states could apply “generally applicable” laws federal agents. They also argued that the law was important to address public safety concerns.
