Ninth Circuit Blocks California Law on Federal Immigration Agent Identification

Court Ruling on California's No Vigilantes Act
On April 22, 2026, the Ninth Circuit Court of Appeals issued a ruling blocking California's No Vigilantes Act, which mandated that federal immigration agents, including those from Immigration and Customs Enforcement (ICE), visibly display identification while on duty. The court found that the law violated the Supremacy Clause of the U.S. Constitution, which prohibits states from regulating federal operations. Judge Mark J. Bennett, writing for the three-judge panel, stated that the law “attempts to directly regulate the United States in its performance of governmental functions.”
The Trump administration had challenged the law shortly after its passage in September 2025, arguing that it posed safety risks to federal officers by exposing them to potential harassment and violence. The administration contended that the law infringed upon the federal government's authority to determine how its officers operate.
Background and Legislative Context
The No Vigilantes Act was part of a broader legislative effort in California aimed at increasing transparency and accountability in law enforcement, particularly in response to aggressive immigration enforcement tactics employed by the Trump administration. Alongside the ID requirement, the law also sought to ban masks for federal agents, a measure that was previously blocked by a federal judge in February 2026 for discriminating against federal officers.
California's legal team argued that the ID requirement applied equally to all law enforcement officers and was necessary for public safety. However, the Ninth Circuit ultimately sided with the federal government, emphasizing that the law specifically targeted federal agents and thus overstepped state authority.
Official Statements and Responses
U.S. Attorney Bill Essayli characterized the ruling as a “huge legal victory,” reinforcing the federal stance against state regulations that interfere with federal law enforcement operations. California Attorney General Rob Bonta's office expressed disappointment, stating that transparency and accountability are essential for good law enforcement, and criticized the Trump administration for deploying unidentified agents in immigration enforcement.
Criticism and Opposition
Critics of the ruling argue that the decision undermines state efforts to ensure accountability among federal law enforcement officers. California lawmakers had framed the No Vigilantes Act as a necessary measure to protect civil liberties and public safety, especially in light of heightened tensions surrounding immigration enforcement.
Conflicting Reports and Gaps
While the Ninth Circuit's ruling has been widely reported as a definitive legal victory for the Trump administration, some sources indicate that California may still pursue options to challenge the decision or seek a review by the full Ninth Circuit or the Supreme Court. The implications of this ruling could lead to a patchwork of conflicting laws across states as other jurisdictions consider similar measures.
What's Next
The Ninth Circuit's injunction will remain in place while the case continues to unfold, potentially setting the stage for further legal battles over the balance of state and federal authority in law enforcement practices. As more states contemplate similar legislation, the outcome of this case may influence future legal interpretations of the Supremacy Clause and state rights in regulating federal operations.
