The Cause of Justification in Exercising a Presidential Veto in the U.S. Constitution攀* Full-Time Lecturer, Wonkwang University攀攀Kang, Seung-Sik* A presidential veto is the rejection of a bill passed by the majority votes of Congress. While Congress can vote to override a presidential veto, causing the bill to become law without the president's approval, this is rarely done. More often than not, the threat of presidential veto is sufficient motivation for Congress to modify the bill prior to its final passage. Across the range of presidential systems, the Presidential veto is the president's most consistent and direct connection with legislative process. Theoretically, it is considered the primary check of the president on congressional power. It can tip the balance of power between congress and the executive strongly toward on or the other, and can do so without affecting the principle central to presidential system that origin and survival of the two branches remain independent. A presidential veto was worked out for checking legislative powers and protecting the Constitution in the U.S. Constitution. Moreover, the Constitution of the presidential system provides a limited power for the president in the policy-making process. So the president have to aggressively veto legislation that violates the Constitution. On the other hand, the president should exercise the veto power with prudence when the presented legislation does not substantially concern either the Constitution or compelling national interests, and when, in his view, the legislation is politically unacceptable.
