The Line Item Veto Act, P.L. 104-130, allowed the President, within five days (excluding Sundays) after signing a bill, to cancel in whole three types of revenue provisions within the bill. The cancellation would take effect upon receipt by Congress of a special message from the President. Congress could "override" the line-item veto by enacting a disapproval bill that would make the cancellation message null and void. On June 25, 1998, the U.S. Supreme Court held the Line Item Veto Act unconstitutional.
