On August 3, 2026, U.S. District Judge Mae D’Agostino of the Northern District of New York issued a preliminary injunction blocking a New York law that would have prohibited Immigration and Customs Enforcement (ICE) agents from wearing masks during enforcement operations. The 51-page ruling represents a significant federal court victory against a state attempting to restrict federal agency operations.
The case hinged on constitutional authority. New York’s law, enacted in May 2026 by the state’s Democratic legislature and signed by Governor Kathy Hochul, contained two separate provisions: one banning mask-wearing by ICE, FBI, DEA, and CBP agents during enforcement operations; another prohibiting state and local cooperation with ICE through the 287(g) program, which allows trained local officers to perform certain immigration enforcement functions.
Judge D’Agostino blocked the mask provision but allowed the 287(g) cooperation ban to remain in effect. The reasoning focused on the Supremacy Clause of the U.S. Constitution, which establishes that federal law supersedes state law when they conflict. D’Agostino found that New York cannot dictate operational procedures for federal law enforcement agencies, as this would impermissibly interfere with federal authority.
The Trump administration’s Department of Justice challenged both provisions through the federal court system. The administration’s arguments emphasized federal supremacy and the inability of states to regulate federal agency conduct. Federal prosecutors argued that state restrictions on federal agents’ operational choices would create an untenable patchwork where federal law enforcement faced 50 different sets of regulations depending on geography.
Judge D’Agostino, an appointee of President Barack Obama, applied constitutional law principles that transcended partisan politics. Courts have consistently held that states cannot restrict federal agency operations—even when state governments disagree with federal policies. The preliminary injunction allows the legal challenge to proceed through the court system, with ultimate resolution potentially reaching the Supreme Court if appealed.
New York Governor Kathy Hochul and Attorney General Letitia James issued a joint statement expressing disappointment with the ruling while reaffirming the state’s commitment to immigration policy. The state indicated it would continue pursuing its constitutional law arguments and might appeal the decision.
The case illustrates ongoing tensions between federal and state authority regarding immigration enforcement. States like New York have increasingly attempted to challenge Trump administration immigration policies through state-level legislation, but the courts have generally sided with federal supremacy in matters involving federal agencies and federal law.
The remaining provision—banning 287(g) cooperation agreements—was allowed to proceed because states do have some authority over their own resources and employees. Judge D’Agostino distinguished between regulating federal agents (impermissible) and regulating state participation in federal programs (more permissible, though still facing legal questions). The 287(g) program is voluntary on the state and local level, giving states and municipalities greater leverage in such arrangements.
