An Obama-appointed federal judge blocked New York from enforcing its ban on face coverings and identification requirements for federal immigration agents, ruling the state overstepped its constitutional authority in a direct rebuke to Governor Kathy Hochul.
U.S. District Judge Mae D'Agostino, sitting in the Northern District of New York, issued a preliminary injunction Monday that prevents the state from enforcing two central provisions of a law aimed at federal agents carrying out immigration operations. The first provision banned agents from wearing masks. The second required them to display visible identification while on duty. Both are now blocked while the legal challenge moves forward.
The ruling handed the Trump administration another courtroom win in its ongoing clash with Democratic-led states over immigration enforcement. Judge D'Agostino found the challenged provisions likely violate the Constitution because they attempt to dictate how federal law enforcement agencies, including ICE, the FBI, the DEA, and Customs and Border Protection, conduct their operations.
Judge D'Agostino, appointed by President Obama, grounded her decision in the supremacy clause, the constitutional principle that federal law overrides conflicting state law, and in what courts call the intergovernmental immunity doctrine, which bars states from directly regulating the federal government's own agents. The New York Post reported that the judge found New York's law violated this doctrine because it imposed state regulations on federal employees performing federal duties.
In her ruling, D'Agostino was direct about the limits of state power. Fox News reported the judge wrote:
"New York cannot impose its own uniform requirements on federal agents simply because it disagrees with how the Federal Government is exercising its authority."
She also drew a clear line between policy disagreement and constitutional authority, stating that the case before her was not about transparency or preferred policy choices, it was about whether a state has the legal power to regulate federal agents at all.
AP News reported the judge framed the question sharply:
"The issue now before the Court is about constitutionality, not transparency or preferable policy decisions."
That distinction matters. Hochul and her allies marketed the mask ban as a public-safety measure, a way to ensure accountability during immigration operations. The court said the real question was simpler: does a state get to tell federal agents what to wear? The answer, under the Constitution, was no.
The Department of Justice brought the challenge, arguing that New York's law amounted to an illegal attempt by a state to regulate the federal government. Just The News reported that Judge D'Agostino partially granted the DOJ's request for a preliminary injunction, ruling that the federal government is likely to succeed when the case goes to trial.
The judge put it plainly: "The law is clear that the federal government, and not the states, set the policies that apply to the enforcement of federal immigration laws."
DHS General Counsel James Percival piled on after the ruling. The Washington Examiner reported Percival's statement:
"Blue states continue to stack losses as they try to pass unconstitutional bans on ICE officers wearing masks."
The DOJ itself called the outcome straightforward, stating that "laws banning federal agents from wearing protective masks are unconstitutional."
Percival's framing, "stack losses", points to a pattern. This was not an isolated defeat for progressive state officials. Courts have now blocked similar mask-ban laws in multiple states, each time on the same constitutional grounds.
New York was not the first state to try this approach, and it was not the first to lose. The Trump administration previously won a comparable case against California, where Governor Gavin Newsom signed a similar law banning masks for law enforcement agents involved in deportation operations. That law was also blocked in federal court, in a ruling that came down in February.
The DOJ has also filed a federal lawsuit against Connecticut over a comparable state law, extending the legal campaign against what the administration views as unconstitutional state interference with federal immigration enforcement.
The pattern is now well established. Democratic governors sign laws restricting how federal agents dress or identify themselves during immigration operations. The DOJ sues. Federal judges, including, in New York's case, one appointed by a Democratic president, rule that the Constitution does not give states that power. Hochul's law, in this respect, was not a novel legal theory. It was a losing one that had already been tested.
Hochul has clashed repeatedly with the Trump administration over federal authority in New York. She has sparred with the president on issues ranging from transit strikes to immigration policy, and the mask ban was only one piece of a broader legislative package aimed at limiting federal enforcement within the state.
Governor Hochul and Attorney General Letitia James issued a joint statement after the ruling, acknowledging the injunction but refusing to concede the broader argument. They said:
"While the court enjoined enforcement of New York's mask ban, we stand firm in our belief that masked agents do not make New York safer and our offices are reviewing all legal options at this time."
The statement is notable for what it does not say. Hochul and James do not dispute the court's constitutional reasoning. They do not cite a legal precedent in their favor. They offer a policy preference, "masked agents do not make New York safer", that the judge explicitly said was beside the point. The court ruled this case is about constitutionality, not about which policy the governor prefers.
A former Democratic governor has called Hochul's anti-ICE legislative package a "serious blunder," and Monday's ruling did nothing to disprove that assessment.
Hochul and James did find one piece of the ruling to celebrate. Judge D'Agostino declined to block a separate provision of the law that bars New York's local law enforcement agencies from entering into 287(g) agreements, the federal program under which local police can be deputized to perform certain immigration enforcement functions. The judge found that participation in such agreements is voluntary under federal law, and that New York's refusal to participate does not amount to discrimination against the federal government.
D'Agostino wrote that "the State's refusal to cooperate in the immigration context, a possibility contemplated by the relevant federal statutes, does not constitute discrimination against the federal government."
Hochul and James seized on this portion, stating:
"As we have said from the start, New York's ban on 287(g) agreements is legal and will keep our communities safe. Local law enforcement should be focused on local matters, and New York taxpayers should not have to foot the bill for any collaboration with ICE."
But the 287(g) provision was always the less consequential piece. The mask ban and the identification mandate were the provisions designed to hamstring federal agents during active operations, and those are the provisions the court struck down.
The injunction does not protect ICE alone. Judge D'Agostino's ruling covers agents from four federal agencies: ICE, the FBI, the DEA, and Customs and Border Protection. The court found that New York's law interfered with the operations of all four, not just immigration enforcement.
That breadth matters. Hochul framed her law as a response to immigration enforcement tactics, but the statute as written reached far beyond ICE. It would have applied to FBI agents conducting counterterrorism operations and DEA agents running drug investigations, federal operations that have nothing to do with immigration. The court's ruling reflects that overreach.
The broader fight between the Trump administration and blue-state governors over immigration enforcement continues to escalate. The DOJ has now challenged similar laws in New York, California, and Connecticut, and it has also pressed New York to honor ICE detainers in individual criminal cases where the state has refused to cooperate.
Hochul has also pushed to expand state authority in other areas where federal policy has shifted, including moving to impose state gun controls after the ATF rolled back Biden-era firearms regulations. The governor's willingness to test the boundaries of state power against federal authority is now a defining feature of her administration, and the courts keep drawing those boundaries in the same place.
When a Democratic president's own judicial appointee tells a Democratic governor that the Constitution does not permit what she is doing, the legal argument is settled. The only question left is how many more losses Hochul and her allies will absorb before they stop filing them.
