Appeals Court Strikes Down California's Mandatory ID Law for Federal Immigration Agents
San Francisco, Saturday, 25 April 2026.
On April 22, 2026, an appeals court blocked California’s mandate requiring immigration agents to display ID, ruling that states cannot constitutionally dictate federal law enforcement uniforms or operations.
The Supremacy Clause and Federal Jurisdiction
On April 22, 2026 [alert! ‘Courthouse News incorrectly reports the date of the injunction as April 15, 2026, but official court documents confirm April 22’], a three-judge panel of the U.S. Court of Appeals for the Ninth Circuit granted an injunction pending appeal against the State of California, Governor Gavin Newsom, and Attorney General Rob Bonta [2][3][5]. The ruling temporarily blocks the enforcement of Section 10 of Senate Bill 805, colloquially known as the “No Vigilantes Act,” which sought to criminalize non-uniformed federal law enforcement officers who failed to visibly display their agency affiliation and name or badge number while on duty [3][5]. The panel issued a unanimous 3-0 ruling, representing a 100% consensus against the state mandate [1].
Origins of the Jurisdictional Clash
The legislative friction traces back to June 2025, when the Trump administration initiated a series of aggressive immigration enforcement operations across Southern California [4][5]. Following highly publicized raids by Immigration and Customs Enforcement (ICE) agents targeting working-class Latinos at locations such as Home Depot parking lots, the federal government deployed National Guard troops to Los Angeles amid growing public outcry [4][5]. In response, Democratic California State Senator Sasha Renée Pérez introduced the No Vigilantes Act on June 23, 2025, arguing that the presence of unidentified personnel conducting “military-sized raids” in civilian clothing created widespread fear and mistrust [5].
