9th Circuit blocks California from enforcing law that would make ICE show visible ID

The 9th U.S. Circuit Court of Appeals has blocked California from enforcing a state law that would have obliged federal immigration agents to show visible identification while on duty. The court’s order pauses state enforcement while the Justice Department’s lawsuit challenging the law proceeds, reversing an earlier lower-court decision that had denied such relief.

California’s No Vigilantes Act provision requiring federal officers to identify themselves was enacted by Gov. Gavin Newsom as part of legislation he signed in September 2025, and the Justice Department filed suit against California, Newsom and Attorney General Rob Bonta in November 2025.

The Justice Department argued in its lawsuit that the state cannot dictate how federal agents carry out their duties; the Court of Appeals granted the federal government the injunction that prevents California from applying the ID requirement to federal immigration personnel for now.

Reporting differs slightly on the permanence of the block: one outlet describes the 9th Circuit as permanently barring enforcement, while another frames the order as a preliminary injunction that pauses enforcement while litigation continues.

California policy advocates and state officials framed the law as a check on federal immigration operations after widely reported federal enforcement actions in the state; the bill’s proponents tied it to recent operations such as a federal operation in MacArthur Park in June that targeted illegal narcotics activity, which state reporting cited as context for the legislation.

The federal government contends the statute conflicts with federal authority over immigration enforcement and pointed to separation-of-powers and federal preemption arguments in court filings; the court’s injunction reflects that legal dispute but does not resolve the underlying merits.

Coverage also places the ruling amid a charged national debate over immigration enforcement and notes, in passing, reporting about increases in federal immigration hires and public disapproval of federal immigration policy, which informed the political backdrop for California’s legislation.

With the injunction in place, the immediate practical effect is that California officials cannot compel ICE or other federal immigration agents to wear visible identification while carrying out federal duties; the broader legal contest will proceed through the courts as the Justice Department’s challenge continues.
