A Biden-appointed judge dealt the Trump administration another legal blow Thursday, tossing its lawsuit seeking to upend New York City’s sanctuary policies after ruling that the Justice Department’s arguments amounted to a “backdoor around the Tenth Amendment.”
The Trump administration sued New York City in July 2025, alleging that its sanctuary laws unlawfully hinder federal immigration enforcement by restricting local law enforcement’s cooperation with federal authorities.
The New York City case is one of more than two dozen lawsuits the Trump administration has filed against state and local jurisdictions over sanctuary and related policies restricting cooperation with federal immigration authorities.
But U.S. District Judge Ramón E. Reyes Jr. ruled the federal government lacked standing to challenge New York City’s restrictions on honoring ICE detainers and rejected the Justice Department’s claims that the city’s sanctuary policies are preempted by federal law.
