But it may be again asked, Who is to judge of the NECESSITY and PROPRIETY of the laws to be passed for executing the powers of the Union? I answer, first, that this question arises as well and as fully upon the simple grant of those powers as upon the declaratory clause; and I answer, in the second place, that the national government, like every other, must judge, in the first instance, of the proper exercise of its powers, and its constituents in the last. If the federal government should overpass the just bounds of its authority and make a tyrannical use of its powers, the people, whose creature it is, must appeal to the standard they have formed, and take such measures to redress the injury done to the Constitution as the exigency may suggest and prudence justify. The propriety of a law, in a constitutional light, must always be determined by the nature of the powers upon which it is founded. Suppose, by some forced constructions of its authority (which, indeed, cannot easily be imagined), the Federal legislature should attempt to vary the law of descent in any State, would it not be evident that, in making such an attempt, it had exceeded its jurisdiction, and infringed upon that of the State? Suppose, again, that upon the pretense of an interference with its revenues, it should undertake to abrogate a landtax imposed by the authority of a State; would it not be equally evident that this was an invasion of that concurrent jurisdiction in respect to this species of tax, which its Constitution plainly supposes to exist in the State governments? If there ever should be a doubt on this head, the credit of it will be entirely due to those reasoners who, in the imprudent zeal of their animosity to the plan of the convention, have labored to envelop it in a cloud calculated to obscure the plainest and simplest truths.
But it is said that the laws of the Union are to be the SUPREME LAW of the land. But what inference can be drawn from this, or what would they amount to, if they were not to be supreme? It is evident they would amount to nothing. A LAW, by the very meaning of the term, includes supremacy. It is a rule which those to whom it is prescribed are bound to observe. This results from every political association. If individuals enter into a state of society, the laws of that society must be the supreme regulator of their conduct. If a number of political societies enter into a larger political society, the laws which the latter may enact, pursuant to the powers intrusted to it by its constitution, must necessarily be supreme over those societies, and the individuals of whom they are composed. It would otherwise be a mere treaty, dependent on the good faith of the parties, and not a goverment, which is only another word for POLITICAL POWER AND SUPREMACY. But it will not follow from this doctrine that acts of the large society which are NOT PURSUANT to its constitutional powers, but which are invasions of the residuary authorities of the smaller societies, will become the supreme law of the land. These will be merely acts of usurpation, and will deserve to be treated as such. Hence we perceive that the clause which declares the supremacy of the laws of the Union, like the one we have just before considered, only declares a truth, which flows immediately and necessarily from the institution of a federal government. It will not, I presume, have escaped observation, that it EXPRESSLY confines this supremacy to laws made PURSUANT TO THE CONSTITUTION; which I mention merely as an instance of caution in the convention; since that limitation would have been to be understood, though it had not been expressed.
Though a law, therefore, laying a tax for the use of the United States would be supreme in its nature, and could not legally be opposed or controlled, yet a law for abrogating or preventing the collection of a tax laid by the authority of the State, (unless upon imports and exports), would not be the supreme law of the land, but a usurpation of power not granted by the Constitution. As far as an improper accumulation of taxes on the same object might tend to render the collection difficult or precarious, this would be a mutual inconvenience, not arising from a superiority or defect of power on either side, but from an injudicious exercise of power by one or the other, in a manner equally disadvantageous to both. It is to be hoped and presumed, however, that mutual interest would dictate a concert in this respect which would avoid any material inconvenience. The inference from the whole is, that the individual States would, under the proposed Constitution, retain an independent and uncontrollable authority to raise revenue to any extent of which they may stand in need, by every kind of taxation, except duties on imports and exports. It will be shown in the next paper that this CONCURRENT JURISDICTION in the article of taxation was the only admissible substitute for an entire subordination, in respect to this branch of power, of the State authority to that of the Union.
