A federal appeals court has blocked a California law requiring federal immigration agents to wear visible identification, ruling that the state overstepped its authority by attempting to regulate federal operations. The three-judge panel of the U.S. Court of Appeals for the Ninth Circuit found that the law violated the Supremacy Clause of the Constitution, which prohibits states from directly regulating federal government functions.
Core Facts
The ruling, issued Wednesday, struck down Section 10 of California’s No Vigilantes Act, which mandated that federal law enforcement officers, including Immigration and Customs Enforcement (ICE) agents, display identification while on duty. The court concluded that the law “attempts to directly regulate the United States in its performance of governmental functions,” a violation of the Supremacy Clause. The panel included two Trump appointees and one Obama appointee.
Background and Context
The law was passed in 2025 and signed by Governor Gavin Newsom in response to public concerns over unidentified federal agents conducting operations in California. The Trump administration sued to block the law, arguing that it would compromise officer safety and federal authority. A lower court initially upheld the ID requirement but blocked a related mask ban, finding it discriminated against federal officers.
Legal and Political Reactions
The Department of Justice welcomed the ruling, stating that it reaffirmed federal supremacy in law enforcement operations. California officials, however, expressed disappointment, arguing that the law was necessary to ensure accountability and public safety. The state contended that the law applied equally to all law enforcement officers, not just federal agents, and that it addressed confusion and potential harm caused by unidentified officers.
Broader Implications
The decision highlights ongoing tensions between states and the federal government over immigration enforcement and law enforcement regulations. It also underscores the legal limits of state authority in areas where federal operations are involved. The ruling may influence similar laws in other states seeking to regulate federal agents.
