A federal appeals court has overturned California’s 'No Vigilantes Act,' a law aimed at federal agents. The Ninth Circuit ruled that these identification requirements violate the Supremacy Clause of the U.S. Constitution.

The failed mandate for ICE and DOJ agents to display ID

The 'No Vigilantes Act' (NVA) was a California law passed last August that targeted non-uniformed federal law enforcement officers. According to the Ninth Circuit's decision, the mandate would have required agents from U.S. Immigration and Customs Enforcement (ICE), federal marshals , and Department of Justice attorneys to visibly display identification while performing their duties.

Beyond simple identification, the law sought to grant California the power to criminally prosecute federal officials who failed to comply with these state-imposed rules . The court found that such a mechanism would create an unlawful layer of state oversight that interferes with the execution of federal law.

From McCulloch to Neagle: The legal pillars of the ruling

The Ninth Circuit's decision relies heavily on established constitutional precedents regarding intergovernmental immunity. In the opinion written by Judge Timothy H. patterson for the nine-judge panel, the court cited the 1819 McCulloch v. Maryland case to demonstrate that states cannot impede federal authority.

The ruling also drew upon the 1890 In re Neagle case, which prevented states from prosecuting federal marshals performing their duties. As the report indicates, the court concluded that the NVA would "unlawfully endanger the execution of federal law" by allowing states to regulate the personnel and operations of the federal government.

A "political blow" to Governor Gavin Newsom's border strategy

Governor Gavin Newsom has frequently clashed with federal immigration authorities, often characterizing federal agents as "secret police." The invalidation of the NVA represents a significant setback for the Governor's efforts to assert state sovereignty and curb federal immigration activity through executive orders and state-funded litigation.

While California argued that the NVA did not substantially burden federal law enforcement, the court rejected this claim. The Ninth Circuit maintained that any state law attempting to directly regulate the conduct of the federal government is inherently void under the Supremacy Clause.

The Ninth Circuit's precedent for other states drafting similar statutes

The ruling establishes a significant judicial benchmark for other states currently drafting similar legislation.. While the decision provides a clear legal standard, several questions remain regarding the future of state-led immigration oversight. it is currently unclear how other states will adjust their legislative language to avoid similar constitutional challenges.

Furthermore, it remains unknown whether the Trump administration or the Department of Justice will appeal this decision to the Supreme Court. Such an appeal would be the ultimate test of whether this ruling becomes a permanent fixture of federal-state immigration relations.
