- On review, the United States Supreme Court affirmed that the cancellation procedures set forth in the Act violated the Presentment Clause of the Constitution, U.S. Constitutional Article I, § 7, cl. 2.
- The Court held that constitutional silence on the subject of unilateral Presidential action that either repeals or amends parts of duly enacted statutes is equivalent to an express prohibition.
- Thus, cancellations pursuant to the Act had no legal force or effect and failed to satisfy the procedures set out in Article I, § 7.
Judgment was affirmed in favor of appellees because the cancellation procedures authorized by the Line Item Veto Act were not authorized by the Constitution.
