Train v. City of New York (1975)
The Nixon administration's EPA withheld billions in water-pollution control money that Congress had appropriated under the Clean Water Act. New York City and other cities sued to force the funds out. The Supreme Court ruled unanimously that the administrator could not refuse to allot the money Congress directed be spent.
The EPA had to release the impounded water-cleanup funds to states and cities.
The case became a marker for limits on the executive's power to refuse spending Congress has mandated.
Both cases turn on the same question: can the executive branch refuse to spend environmental money Congress already appropriated?
