The Ninth Circuit Court of Appeals on Wednesday issued an injunction blocking a California law that required Immigration and Customs Enforcement (ICE) officials to refrain from wearing masks and to display their I.D.

"We conclude that § 10 of the No Vigilantes Act attempts to directly regulate the United States in its performance of governmental functions," the court wrote. "The Supremacy Clause forbids the State from enforcing such legislation. The United States is therefore likely to succeed on the merits of its Supremacy Clause claim, and the other preliminary injunction factors also weigh in its favor. Thus, we grant the motion for an injunction pending appeal.”

The decision is a win for the Trump administration, which has faced considerable opposition from blue states to its mass deportation efforts. Los Angeles, in 2025, was the site of anti-ICE riots that prompted President Donald Trump to send in the National Guard.

First Assistant U.S. Attorney for the Central District of California Bill Essayli celebrated the decision as a "huge legal victory."

The Ninth Circuit oversees much of the western United States, including California, Oregon, Washington, Idaho, Montana, Nevada, Arizona, Alaska, and Hawaii.
