Federal appeals court blocks California law requiring federal agents to wear identification

LOS ANGELES — An appeals court has blocked a California law passed in 2025 requiring federal immigration agents to wear a badge or some form of identification.

The Trump administration filed a lawsuit in November challenging the law, arguing that it would threaten the safety of officers who are facing harassment, doxing, and violence and that they violated the constitution because the state is directly regulating the federal government.

A three-judge panel of the 9th U.S. Circuit Court of Appeals issued an injunction pending appeal Wednesday. It had already granted a temporary administrative injunction to block the implementation of the law.

This is a developing story.
