It is easy to see, that in the exercise of these Legislative powers, it will frequently happen that laws are enacted, which, in their operation, will embarrass the intercourse of two nations. Such are always the effect of retaliating laws, and aliens within the limits of a foreign jurisdiction are frequently, by those regulations, subjected to great and unreasonable embarrassments.
The Treaty-making power operates in a very different manner; its power is limited and confined to the forming of Treaties with foreign nations; its objects are to facilitate the intercourse between nations; to remove by contract, those impediments which embarrass that intercourse, and to place the same on a fair and just foundation. In the exercise of this power, it will unavoidably happen that the laws of the Legislature are sometimes infracted. The Legislature, for certain causes,—perhaps to compel a foreign nation to form a treaty on terms of reciprocity,—may prohibit all intercourse, or embarrass that intercourse with regulations so burdensome as to produce the same effect; the foreign nation finally becomes willing to treat, and to establish an intercourse on equitable terms. If, in this case, the Treaty power cannot touch the laws of the Legislature, the object which gave rise to those very laws can never be attained; no Treaty can be formed, because it will oppose existing laws; those laws cannot be repealed, because the object for which they were enacted has not been attained. Such a construction of the Treaty power would defeat every object for which that power was established; and instead of possessing an authority to remove embarrassments in a foreign intercourse, it cannot touch them; and, although expressly created for the attainment of a single object, it can never attain it.
From these considerations, he contended that, in the exercise of that power which related to the intercourse with foreign nations, the Treaty-making was paramount to the Legislative power; and that the positive institutions of the Legislature must give place to compact.
On this construction, a perfect harmony is introduced into the departments of Government. Both the Legislative and the Treaty power are necessary, on many occasions, to accomplish the same objects. The Legislative power to establish regulations, or declare war, for the purpose of compelling a nation to agree to a reasonable compact; and the Treaty power, when that nation is compelled to agree to such reasonable compact, to remove by Treaty those very regulations, and the war itself, on fair and equitable terms.
Mr. Madison said, that the direct proposition before the House, had been so absorbed by the incidental question which had grown out of it, concerning the constitutional authority of Congress in the case of Treaties, that he should confine his present observations to the latter.
The true question, therefore, before the committee, was, not whether the will of the people expressed in the constitution was to be obeyed, but how that will was to be understood; in what manner it had actually divided the powers delegated to the Government; and what construction would best reconcile the several parts of the instrument with each other, and be most consistent with its general spirit and object.
On comparing the several passages in the constitution, which had been already cited to the committee, it appeared, that if taken literally, and without limit, they must necessarily clash with each other. Certain powers to regulate commerce, to declare war, to raise armies, to borrow money, &c., are first specially vested in Congress. The power of making Treaties, which may relate to the same subjects, is afterwards vested in the President and two-thirds of the Senate; and it is declared in another place, that the constitution and the Laws of the United States, made in pursuance thereof, and Treaties made, or to 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 term supreme, as applied to Treaties, evidently meant a supremacy over the State constitutions and laws, and not over the Constitution and Laws of the United States. And it was observable, that the judicial authority, and the existing laws, alone of the States, fell within the supremacy expressly enjoined. The injunction was not extended to the Legislative authority of the States, or to laws requisite to be passed by the States for giving effect to Treaties; and it might be a problem worthy of the consideration, though not needing the decision of the committee, in what manner the requisite provisions were to be obtained from the States.
It was to be regretted, he observed, that on a question of such magnitude as the present, there should be any apparent inconsistency or inexplicitness in the constitution, that could leave room for different constructions. As the case, however, had happened, all that could be done was to examine the different constructions with accuracy and fairness, according to the rules established therefor, and to adhere to that which should be found most rational, consistent, and satisfactory.
He stated the five following, as all the constructions, worthy of notice, that had either been contended for, or were likely to occur:
