In the organization of the Government of the United States the legislative and executive functions were separated and placed in distinct hands. Although the President is required from time to time to recommend to the consideration of Congress such measures as he shall judge necessary and expedient, his participation in the formal business of legislation is limited to the single duty, in a certain contingency, of demanding for a bill a particular form of vote prescribed by the Constitution before it can become a law. He is not invested with power to defeat legislation by an absolute veto, but only to restrain it, and is charged with the duty, in case he disapproves a measure, of invoking a second and a more deliberate and solemn consideration of it on the part of Congress. It is not incumbent on the President to sign a bill as a matter of course, and thus merely to authenticate the action of Congress, for he must exercise intelligent judgment or be faithless to the trust reposed in him. If he approve a bill, he shall sign it, but if not he shall return it with his objections to that House in which it shall have originated for such further action as the Constitution demands, which is its enactment, if at all, not by a bare numerical majority, as in the first instance, but by a constitutional majority of two-thirds of both Houses. While the Constitution thus confers on the legislative bodies the complete power of legislation in all cases, it proceeds, in the spirit of justice, to provide for the protection of the responsibility of the President. It does not compel him to affix the signature of approval to any bill unless it actually have his approbation; for while it requires him to sign if he approve, it, in my judgment, imposes upon him the duty of withholding his signature if he do not approve. In the execution of his official duty in this respect he is not to perform a mere mechanical part, but is to decide and act according to conscientious convictions of the rightfulness or wrongfulness of the proposed law. In a matter as to which he is doubtful in his own mind he may well defer to the majority of the two Houses. Individual members of the respective Houses, owing to the nature, variety, and amount of business pending, must necessarily rely for their guidance in many, perhaps most, cases, when the matters involved are not of popular interest, upon the investigation of appropriate committees, or, it may be, that of a single member, whose attention has been particularly directed to the subject. For similar reasons, but even to a greater extent, from the number and variety of subjects daily urged upon his attention, the President naturally relies much upon the investigation had and the results arrived at by the two Houses, and hence those results, in large classes of cases, constitute the basis upon which his approval rests. The President's responsibility is to the whole people of the United States, as that of a Senator is to
