A group of New York City and State transit authorities have sued the U.S. Department of Transportation (DOT) over Secretary Duffy's decision to rescind federal funding for New York City's Congestion Pricing Program. On February 19, 2025, Secretary Duffy wrote a letter to New York Governor Kathy Hochul informing her that the Federal Highway Administration (FHWA) no longer approved of New York City's use of congestion pricing, despite DOT and FHWA having previously approved the plan. The plaintiffs argue that the decision to rescind approval for congestion pricing violates their Fifth Amendment Right to due process, as well as the Administrative Procedure Act and the National Environmental Policy Act. The plaintiffs requested that the court declare Secretary Duffy's decision unlawful and prevent the defendants from rescinding approval and funding.
