Nixon's impoundment fights (1973–1974)
President Nixon refused to spend money Congress had appropriated for programs he opposed. States and agencies sued, and courts repeatedly ordered the funds released. Congress then passed a law limiting the practice.
Courts forced the money out, ruling the president could not simply refuse to spend it.
The 1974 Impoundment Control Act set rules for when a president can withhold appropriated funds.
The core question is the same: how far the executive branch can go in withholding money Congress already approved.
