A U.S. court granted a motion to dismiss the Trump administration's lawsuit challenging Los Angeles' sanctuary city ordinance, according to the Los Angeles City Attorney's office on June 23, 2026. The ruling is a setback for a broader federal legal campaign to compel local jurisdictions to cooperate with immigration enforcement.

The conflict reflects a sustained clash between the Trump administration's second-term agenda and cities that have adopted policies limiting their role in federal immigration enforcement. The Justice Department filed suit against Los Angeles in June 2025, arguing the city's sanctuary ordinance violates federal law. That case was part of a wider strategy: DOJ subsequently sued New York City in July 2025 and Minnesota in September 2025, and published a formal list of jurisdictions it deemed non-compliant with federal immigration law.

Los Angeles' Sanctuary Framework

Los Angeles has two layers of protection for immigrants. Special Order 40, issued in 1979, restricted the LAPD from contacting federal immigration authorities. A second layer came in November 2024, when the City Council passed an ordinance formally designating Los Angeles a sanctuary city and explicitly prohibiting city officials and police from assisting federal immigration agents. Together, these policies created a legal barrier that the Justice Department argues violates federal immigration law and the Supremacy Clause — a constitutional provision that gives federal law priority over state and local law when they conflict.

The DOJ's core argument rests on preemption doctrine: that federal immigration statutes impose duties on state and local governments to assist federal enforcement. Los Angeles counters using the anti-commandeering doctrine — a constitutional principle, refined in Supreme Court cases like Printz v. United States and Murphy v. NCAA, that the federal government cannot force states or cities to spend their own resources carrying out federal policies.

The court's decision to dismiss the case before trial is procedurally favorable for the city, though the reasoning matters considerably. A dismissal based on standing or ripeness — technical grounds about whether the case is ripe for judicial review — leaves the substantive constitutional question unresolved. A dismissal that directly engages the anti-commandeering framework would carry more weight in future cases. The City Attorney's office has not publicly detailed which grounds the court used, and the full judicial opinion will clarify the decision's broader implications.

A Federal Enforcement Strategy Facing Headwinds

This dismissal is not the administration's first legal setback on sanctuary enforcement. In January 2026, a federal judge denied the Trump administration's motion to dismiss a separate lawsuit challenging the administration's executive orders that threatened to cut federal funding to sanctuary jurisdictions. That denial meant the challenge could proceed to trial. The two rulings combined suggest the federal judiciary has been skeptical of the administration's legal theories in this domain.

Mayor Karen Bass reinforced the city's position on the political level. In July 2025, she issued an executive directive instructing city departments to support immigrant communities, framed explicitly as a response to what the city characterized as unlawful federal immigration enforcement actions. The directive aligned the executive branch formally with the City Council's ordinance.

The litigation landscape remains in flux. The Justice Department's cases against New York City and Minnesota are still active, and the administration can appeal the Los Angeles dismissal. The funding-conditionality track — using federal grant requirements to force immigration cooperation — represents a separate legal avenue that courts have not yet fully resolved. For now, the June 23 ruling has removed one direct legal tool from the federal government's arsenal against Los Angeles.

The substantive question animating the remaining cases is whether courts will view sanctuary ordinances as passive non-cooperation—protected by the anti-commandeering doctrine—or as affirmative obstruction subject to federal preemption. That distinction is not cleanly settled in existing Supreme Court precedent, and it is where these disputes will ultimately turn.
