Had the Constitution been silent on this head, there can be no doubt that all the particular powers requisite as means of executing the general powers would have resulted to the government, by unavoidable implication. No axiom is more clearly established in law, or in reason, than that wherever the end is required, the means are authorized; wherever a general power to do a thing is given, every particular power necessary for doing it is included. Had this last method, therefore, been pursued by the convention, every objection now urged against their plan would remain in all its plausibility; and the real inconveniency would be incurred of not removing a pretext which may be seized on critical occasions for drawing into question the essential powers of the Union. If it be asked what is to be the consequence, in case the Congress shall misconstrue this part of the Constitution, and exercise powers not warranted by its true meaning, I answer, the same as if they should misconstrue or enlarge any other power vested in them; as if the general power had been reduced to particulars, and any one of these were to be violated; the same, in short, as if the State legislatures should violate the irrespective constitutional authorities. In the first instance, the success of the usurpation will depend on the executive and judiciary departments, which are to expound and give effect to the legislative acts; and in the last resort a remedy must be obtained from the people who can, by the election of more faithful representatives, annul the acts of the usurpers. The truth is, that this ultimate redress may be more confided in against unconstitutional acts of the federal than of the State legislatures, for this plain reason, that as every such act of the former will be an invasion of the rights of the latter, these will be ever ready to mark the innovation, to sound the alarm to the people, and to exert their local influence in effecting a change of federal representatives. There being no such intermediate body between the State legislatures and the people interested in watching the conduct of the former, violations of the State constitutions are more likely to remain unnoticed and unredressed. 2. "This Constitution and the laws of the United States which shall be made in pursuance thereof, and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land, and the judges in every State shall be bound thereby, any thing in the constitution or laws of any State to the contrary notwithstanding." The indiscreet zeal of the adversaries to the Constitution has betrayed them into an attack on this part of it also, without which it would have been evidently and radically defective. To be fully sensible of this, we need only suppose for a moment that the supremacy of the State constitutions had been left complete by a saving clause in their favor.
