Status as of October 18, 2026. On October 14, the Ninth U.S. Circuit Court of Appeals ordered a preliminary injunction preventing California from enforcing its visible-identification requirement against federal law enforcement officers, including ICE agents. The state had already been barred from enforcing that provision while the appeal was pending. The new ruling orders more formal preliminary relief; it is not a final judgment resolving the entire lawsuit.
California cannot use its 2025 identification law to require plainclothes ICE officers to display the agency they work for and their name or badge number during immigration enforcement operations. That is the result of a new federal appeals court ruling in a dispute over whether a state can impose rules on officers carrying out federal law.
For people who encounter immigration agents during raids or arrests, the practical point is straightforward: California cannot prosecute federal officers under this specific ID requirement for failing to display the identification it demands. The ruling does not say that federal officers are forbidden from identifying themselves or that every other legal safeguard has disappeared.
What California tried to require
The No Vigilantes Act, SB 805, was enacted in September 2025 amid concern about officers conducting enforcement operations without visible identification. Section 10 of the law, California Penal Code § 13654, generally required non-uniformed law enforcement officers to show their agency and either a name or badge number while making arrests, detaining people or performing crowd-control duties. The statute included exceptions for specified operations and circumstances.
Federal officers were expressly covered. A knowing, willful violation could be prosecuted as a misdemeanor under state law. The act also provided an alternative for agencies that publicly adopted a qualifying identification policy.
The federal government challenged the law before California began enforcing it against federal officers. It argued that California was attempting to control the way federal agents carry out federal duties.
What changed on October 14
This was not the first time the identification rule was blocked. The Ninth Circuit issued temporary protection in February and, on April 22, barred California from enforcing Section 10 against federal officers while the appeal proceeded.
On October 14, following further review, the three-judge panel reversed the district court's refusal to grant a preliminary injunction and directed that court to enter one. The panel went beyond saying the federal government was likely to win: it concluded the United States was certain to succeed in its constitutional challenge to this provision.
The judges relied on the Constitution's Supremacy Clause and the doctrine of intergovernmental immunity. In plain language, a state generally cannot dictate how the federal government performs its own functions unless Congress has authorized that regulation. The panel found no such authorization for California's requirement.
Does this also let ICE agents wear masks?
The identification dispute should not be confused with California's separate No Secret Police Act, SB 627, which addresses facial coverings. Both laws were challenged in the same federal lawsuit. The district court separately issued preliminary relief against the mask ban as applied to federal officers, but the October 14 appeal concerned only Section 10 of the identification law. The panel did not newly decide the mask issue.
The ruling also does not invalidate every provision of SB 805, govern identification practices of state and local police in general, or decide what federal agency policies may require. It addresses California's ability to enforce this particular mandate against federal agencies and their officers.
What happens next
The case returns to federal district court with instructions to enter the preliminary injunction. Other claims in the lawsuit may continue, and later proceedings could change the procedural status. For now, the state identification requirement cannot be applied to federal officers under the court's orders.
Anyone dealing with immigration enforcement should distinguish an officer's visible identification from the separate legal questions of arrest authority, detention and access to a lawyer.
