A United States federal court ruled that the International Emergency Economic Powers Act (IEEPA) does not allow the President to impose broad import tariffs.
The IEEPA was enacted on 28 October 1977 in the United States.
It allows the President to regulate financial transactions after declaring a national emergency.
The Act can be used to freeze assets and restrict economic dealings in response to external threats.
Any emergency declared under this Act must be renewed every year under the National Emergencies Act NEA.
The IEEPA forms the legal basis for many United States economic sanctions.
