Tucker Act Law and Legal Definition

Under the Tucker Act, the United States waived its sovereign immunity as to certain kinds of claims. The Act grants US Courts of Claims jurisdiction to render judgment upon any claim against the United States founded either upon the Constitution, or any Act of Congress or any regulation of an executive department, or upon any express or implied contract with the United States, or for liquidated or unliquidated damages in cases not sounding in tort. The Act permits three kinds of claims against the government: (1) contractual claims, (2) noncontractual claims where the plaintiff seeks the return of money paid to the government and (3) noncontractual claims where the plaintiff asserts that s/he is entitled to payment by the government.
