A federal judge has thrown out the lawsuit filed by the Trump administration targeting New York City's sanctuary laws, ruling that the U.S. government cannot force local authorities to assist in enforcing civil immigration laws.
This decision marks a significant judicial setback for the White House, which has been trying to persuade cities and states to participate in its deportation efforts. The ruling upholds the restrictions that limit the cooperation of local police and other municipal agencies with the Immigration and Customs Enforcement (ICE).
The ruling was issued by Judge Ramón E. Reyes Jr. of the U.S. District Court for the Eastern District of New York, based in Brooklyn. He concluded that the federal government lacked the legal standing to bring the lawsuit and dismissed its claims that federal law took precedence over the challenged municipal provisions.
As reported by The New York Times, the judge elaborated his findings in a 25-page decision, emphasizing that the Constitution protects state and local governments against attempts to commandeer their resources for federal responsibilities.
In his ruling, highlighted by Courthouse News, Reyes asserted that no federal statute mandates states to engage in the federal government's immigration enforcement operations.
The judge also noted that the Trump administration's arguments were an attempt to bypass the Tenth Amendment protections, which limit the federal government's power to impose certain obligations on states and their officials.
Reyes stated, "Even if the United States had standing—and it does not—its arguments regarding the supremacy of federal law fail," according to the judicial news outlet.
Implications for Immigrants in New York
New York's sanctuary laws restrict the circumstances under which police and other municipal agencies can cooperate with federal immigration authorities. They limit the detention of individuals on administrative requests from ICE and the sharing of specific information about those in local custody.
According to Reuters, the judge clarified that the federal administration could not challenge a municipal provision preventing police from holding immigrants solely at the request of immigration authorities, as this practice is also prohibited under New York state law.
Furthermore, the court concluded that municipal rules limiting the disclosure of release dates, locations, and other custody-related data do not conflict with a federal obligation to share that information, as no such obligation exists in the terms outlined by the government.
While the decision does not prevent ICE from operating in New York or conducting immigration arrests independently, it focuses on the city's authority to set limits on the involvement of its employees and the use of municipal resources in these operations.
New York City Mayor Zohran Mamdani praised the ruling as a victory against the Trump administration's deportation policies. "The federal government sought to turn New York City's public servants into deportation agents and divert our resources to enforce ICE's cruel agenda. Today, they lost," Mamdani declared in an official statement.
The mayor emphasized that the resolution reaffirms that Washington cannot commandeer municipal workers' roles to impose immigration enforcement duties.
Murad Awawdeh, president and executive director of the New York Immigration Coalition, welcomed the judicial decision, asserting it protects the ability of state and local authorities to establish their own regulations.
According to Courthouse News, neither the White House nor the Department of Homeland Security immediately responded to requests for comment on the ruling.
Background of the 2025 Lawsuit
The Department of Justice filed the lawsuit in July 2025, contending that New York's sanctuary policies hindered federal agents' work and violated the supremacy of national laws. The government's objections included restrictions on sharing information regarding release dates, court appearances, and custody status of individuals who might face immigration proceedings.
New York City's sanctuary policies date back to 1989 under then-Mayor Edward Koch, although their provisions have evolved over the decades.
The Trump administration has also taken similar measures in court against other jurisdictions, seeking to expand local governments' cooperation with federal immigration authorities.
As reported by The New York Times, federal courts have similarly dismissed challenges to sanctuary policies in other cities and states, including Boston, Chicago, Los Angeles, Colorado, and Minnesota.
