Status as of October 15, 2026. A federal district judge has dismissed the Justice Department's challenge to New York City's sanctuary laws. The laws remain in effect. The ruling is from the U.S. District Court for the Eastern District of New York; no appellate ruling has been issued in this case.

A federal judge in Brooklyn dismissed the Trump administration's lawsuit against New York City's restrictions on cooperation with federal immigration enforcement on October 15. U.S. District Judge Ramón E. Reyes Jr. found that the federal government had not established a legal basis for the relief it sought and that its constitutional arguments failed. The ruling leaves in place city rules limiting when police and jail officials may hold people for Immigration and Customs Enforcement (ICE) or share information about their release.

The 25-page decision in United States v. City of New York, No. 25-cv-04084, does not stop ICE from making its own arrests or carrying out federal immigration law. It addresses a narrower question: whether Washington can require New York City to abandon restrictions on the use of its own employees, facilities and information to assist ICE.

Which New York City laws did the Justice Department challenge?

The lawsuit, filed July 24, 2025, targeted four provisions of the city Administrative Code and an NYPD operations order. Together, they govern the relationship between municipal agencies and federal immigration officers.

  • Section 9-131: limits when the city's Department of Correction may hold someone on an ICE civil immigration detainer, share certain custody information or provide jail space for federal immigration operations.

  • Section 9-205: imposes similar detainer limits on the Department of Probation.

  • Section 14-154: governs how the New York Police Department responds to ICE detainers and requests for notice of release.

  • Section 10-178: generally prohibits the use of city personnel and resources for immigration enforcement while preserving exceptions required by law and certain other lawful cooperation.

  • NYPD Operations Order No. 4: instructs officers not to contact federal civil immigration authorities simply to report an individual's location, consistent with city law.

The detainer rules grew out of city legislation adopted in 2014 and revised in 2017. They are not a complete ban on contact with ICE. As the judge described the statutes, the correction, probation and police departments may generally honor a civil detainer when ICE presents a judicial warrant and the person meets specified serious-crime or terrorism-screening criteria. The police code also contains a narrow temporary-hold provision while a judicial warrant is sought. An ICE administrative warrant or detainer, issued without a judge's approval, is not the same as a judicial warrant.

What did the federal government want?

The Justice Department asked the court to declare the challenged provisions invalid and permanently prevent the city from enforcing them. It argued that federal immigration law takes precedence over local restrictions under the Constitution's Supremacy Clause.

Federal lawyers said the rules obstructed immigration enforcement by preventing local officials from honoring ICE custody requests and sharing release dates, court dates, whereabouts and other information. In the government's account, agents were sometimes forced to locate and arrest people in the community after they had been released from local custody, creating additional risks.

New York City argued that it was entitled to decide how its police officers, correctional staff, facilities and municipal funds would be used. The city also disputed the government's reading of federal laws on immigration-status information.

Why did the judge dismiss the case?

Judge Reyes addressed both the government's right to bring the claims and the legal merits. On detainers, he found that striking down the city ordinances would not give New York police powers they lack under state law. New York law independently bars local officers from making arrests solely for civil immigration violations. Because the requested court order would not remedy that obstacle, the federal government had not established standing on those claims.

On information sharing, the court distinguished a person's citizenship or immigration status from operational information such as a release date or where a person is being held. Federal statutes, including 8 U.S.C. §§ 1373 and 1644, address restrictions on sharing immigration-status information. The challenged city provisions preserve disclosures required by federal law, the judge found; they do not create the conflict alleged by the Justice Department.

Reyes also considered the merits even assuming the federal government had standing. He rejected arguments that federal law expressly displaced the ordinances, occupied the entire relevant field or made compliance with federal immigration law impossible. He relied on the Tenth Amendment's anti-commandeering principle: the federal government cannot generally direct states and cities to administer a federal program using their own personnel and resources. The court likewise rejected claims that the rules unlawfully regulated or discriminated against the federal government.

The opinion went further in its analysis of 8 U.S.C. §§ 1373 and 1644, concluding that those provisions violate the anti-commandeering doctrine as understood by the court. That conclusion is part of a district court ruling in this case, not a nationwide order striking the statutes from the federal code.

What changes for immigrants and ICE now?

For people held by New York City agencies, the decision means the city restrictions challenged in this lawsuit remain in place. A civil ICE detainer does not automatically authorize the NYPD or city jail staff to extend a person's custody after the local basis for detention has ended. Applicable exceptions and independently valid warrants still matter.

For federal officers, the ruling does not remove ICE's immigration-enforcement authority. Agents may pursue arrests under federal law using their own powers and resources. What the ruling rejects is the federal government's attempt to invalidate New York City's rules governing when municipal agencies will help.

It also does not create immunity from deportation for anyone living in New York City. Sanctuary rules address local cooperation with federal enforcement, not eligibility for immigration status or protection against federal removal proceedings.

Where does the lawsuit stand?

The Justice Department filed the complaint in July 2025. New York City moved to dismiss it in December 2025, and the court later requested additional briefing on whether the federal government had standing. On October 15, 2026, Judge Reyes granted the city's motion and directed the clerk to close the case at the district court level.

The United States may seek review in the U.S. Court of Appeals for the Second Circuit. As of October 15, no appeal has been verified in the materials reviewed for this report. The ruling therefore marks a district-court dismissal, not a final nationwide resolution of disputes over sanctuary policies. The federal government has filed similar challenges against other states and cities, including a case concerning Maryland's Community Trust Act.
