Train v. City of New York, 420 U.S. 35 (1975), arose when President Nixon impounded $12 billion in environmental protection grants that Congress had appropriated under the Federal Water Pollution Control Act — even after Congress overrode his veto of the spending bill. EPA Administrator Russell Train was named as defendant when New York City sued to force release of the funds. A unanimous Supreme Court held that the president has no authority to withhold funds Congress appropriated by law. The Court ruled that the president's obligation to "faithfully execute the laws" requires spending money Congress directs, not choosing which appropriations to honor. The decision directly reinforced the Impoundment Control Act of 1974, which Congress had passed the year before partly in anticipation of this constitutional confrontation. Train v. City of New York remains the foundational Supreme Court precedent for the principle that Congress, not the president, controls the federal purse.
Train is the Supreme Court's clearest statement that the president cannot unilaterally nullify a congressional appropriation. When administrations argue that apportionment authority allows them to indefinitely delay spending, Train's unanimous holding stands as the constitutional counter: the president's job is to execute the laws Congress passes, including spending laws. Any modern challenge to executive impoundment — including the 2026 education grant freeze — must contend with Train's holding.
Train v. City of New York is sometimes confused with INS v. Chadha (1983), which struck down the legislative veto. Both cases involve the separation of powers over federal spending, but Train addresses whether the president must spend appropriated funds; Chadha addresses whether Congress can veto executive actions by resolution without presentment to the president.
