President Trump just won a major immigration-enforcement victory in a place Democrats have spent years treating as friendly territory: the Ninth Circuit Court of Appeals.

A unanimous three-judge panel ruled that California cannot dictate how federal law-enforcement officers identify themselves while carrying out duties authorized by Congress. The court ordered a lower judge to block the state from enforcing the identification provision of its so-called “No Vigilantes Act” against the United States, federal agencies and federal officers.

This was not a narrow procedural timeout. The panel said the Trump administration was certain to succeed on its constitutional claim.

The Justice Department’s top Civil Division official quickly highlighted the bottom line and shared the ruling itself.

The fight centered on Section 10 of California Senate Bill 805. The provision generally required a non-uniformed federal officer working in California to display the officer’s agency and either a name or badge number while conducting arrests, detentions or crowd-control operations.

The law included several exemptions, including for undercover work, SWAT operations, protective details and exigent circumstances. But an officer who willfully violated the identification rule could still face misdemeanor prosecution by the state.

That was the constitutional line California could not cross.

In its 21-page opinion, the Ninth Circuit explained that the Supremacy Clause prevents states from directly regulating the federal government’s operations unless Congress clearly authorizes it. California’s rule attempted to control “whether, how, and when” federal officers publicly identify themselves while enforcing federal law.

The panel rejected California’s argument that the government needed to prove the identification rule placed a substantial burden on federal operations. Once a state directly regulates a federal governmental function without congressional permission, the size of the burden is beside the point.

That matters well beyond one badge rule. California was effectively claiming the power to place state-law conditions—and the threat of state criminal prosecution—on officers carrying out federal missions.

The court’s answer was clear: federal supremacy is not optional when Sacramento dislikes Washington’s immigration policy.

The administration also emphasized the practical stakes for officers carrying out immigration duties under federal authority.

The case began after Gov. Gavin Newsom signed the No Vigilantes Act and a companion measure known as the “No Secret Police Act” in September 2025. The Trump administration sued California, Newsom and Attorney General Rob Bonta two months later.

A federal district judge initially blocked California’s restrictions on face coverings for federal officers but declined to block the visible-identification requirement. The Ninth Circuit temporarily froze that requirement in February, issued a longer injunction in April and has now ruled on the merits of the government’s appeal from the lower court’s refusal to grant preliminary relief.

All three judges agreed. The panel included Trump appointees Mark Bennett and Daniel Collins along with Obama appointee Jacqueline Nguyen.

That unanimity makes it much harder for California officials to dismiss the outcome as a partisan favor to the White House.

The current ruling also explains why the court treated the constitutional injury as immediate. Allowing California to enforce an invalid state law against federal officers would itself inflict irreparable harm, while the public interest favors enforcement of the Constitution.

Current coverage captured the key fact that California’s attempt to force visible identification on federal officers is now blocked by a full three-judge panel.

Fox News reports that California defended the requirement as a public-safety measure and argued that it did not unconstitutionally regulate the federal government. Bonta’s office said it was reviewing the decision while accusing the Trump administration of using tactics that threaten civil liberties.

The court did not decide whether visible identification is good policy in the abstract. It decided who has the constitutional authority to set the operating rules for federal officers.

On that question, the judges found California’s position incompatible with more than two centuries of Supremacy Clause law.

The wording of the decision is especially damaging to Newsom’s resistance campaign. California never possessed authority to regulate federal officers in the first place, the panel held, and the state cannot create that power simply by writing a rule that also reaches some state or local officers.

The Ninth Circuit reversed the lower court and sent the case back with instructions to enter a preliminary injunction. California, Newsom and Bonta are barred from enforcing Section 10 against the United States, federal agencies and federal officers while the litigation continues.

For President Trump, this is a clean constitutional win at a crucial moment. His administration challenged California’s attempt to interfere with federal immigration operations, carried the case into a court long associated with liberal rulings, and won unanimously.

Newsom tried to put Sacramento between federal agents and the laws Congress told them to enforce. Even the Ninth Circuit told him no.
