It is obvious that to preserve the system established by the Constitution each of the coordinate branches of the Government—the executive, legislative, and judicial—must be left in the exercise of its appropriate powers. If the executive or the judicial branch be deprived of powers conferred upon either as checks on the legislative, the preponderance of the latter will become disproportionate and absorbing and the others impotent for the accomplishment of the great objects for which they were established. Organized, as they are, by the Constitution, they work together harmoniously for the public good. If the Executive and the judiciary shall be deprived of the constitutional powers invested in them, and of their due proportions, the equilibrium of the system must be destroyed, and consolidation, with the most pernicious results, must ensue—a consolidation of unchecked, despotic power, exercised by majorities of the legislative branch.
The executive, legislative, and judicial each constitutes a separate coordinate department of the Government, and each is independent of the others. In the performance of their respective duties under the Constitution neither can in its legitimate action control the others. They each act upon their several responsibilities in their respective spheres. But if the doctrines now maintained be correct, the executive must become practically subordinate to the legislative, and the judiciary must become subordinate to both the legislative and the executive; and thus the whole power of the Government would be merged in a single department. Whenever, if ever, this shall occur, our glorious system of well-regulated self-government will crumble into ruins, to be succeeded, first by anarchy, and finally by monarchy or despotism. I am far from believing that this doctrine is the sentiment of the American people; and during the short period which remains in which it will be my duty to administer the executive department it will be my aim to maintain its independence and discharge its duties without infringing upon the powers or duties of either of the other departments of the Government.
The power of the Executive veto was exercised by the first and most illustrious of my predecessors and by four of his successors who preceded me in the administration of the Government, and it is believed in no instance prejudicially to the public interests. It has never been and there is but little danger that it ever can be abused. No President will ever desire unnecessarily to place his opinion in opposition to that of Congress. He must always exercise the power reluctantly, and only in cases where his convictions make it a matter of stern duty, which he can not escape. Indeed, there is more danger that the President, from the repugnance he must always feel to come in collision with Congress, may fail to exercise it in cases where the preservation of the Constitution from infraction, or the public good, may demand it than that he will ever exercise it unnecessarily or wantonly.
