2. "No State shall, without the consent of the Congress, lay any imposts or duties on imports or exports, except what may be absolutely necessary for executing its inspection laws, and the net produce of all duties and imposts laid by any State on imports or exports, shall be for the use of the treasury of the United States; and all such laws shall be subject to the revision and control of the Congress. No State shall, without the consent of Congress, lay any duty on tonnage, keep troops or ships of war in time of peace, enter into any agreement or compact with another State, or with a foreign power, or engage in war unless actually invaded, or in such imminent danger as will not admit of delay."
The restraint on the power of the States over imports and exports is enforced by all the arguments which prove the necessity of submitting the regulation of trade to the federal councils. It is needless, therefore, to remark further on this head, than that the manner in which the restraint is qualified seems well calculated at once to secure to the States a reasonable discretion in providing for the conveniency of their imports and exports, and to the United States a reasonable check against the abuse of this discretion. The remaining particulars of this clause fall within reasonings which are either so obvious, or have been so fully developed, that they may be passed over without remark.
The SIXTH and last class consists of the several powers and provisions by which efficacy is given to all the rest.
1. Of these the first is, the "power to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof."
Few parts of the Constitution have been assailed with more intemperance than this; yet on a fair investigation of it, no part can appear more completely invulnerable. Without the SUBSTANCE of this power, the whole Constitution would be a dead letter. Those who object to the article, therefore, as a part of the Constitution, can only mean that the FORM of the provision is improper. But have they considered whether a better form could have been substituted?
There are four other possible methods which the Constitution might have taken on this subject. They might have copied the second article of the existing Confederation, which would have prohibited the exercise of any power not EXPRESSLY delegated; they might have attempted a positive enumeration of the powers comprehended under the general terms "necessary and proper"; they might have attempted a negative enumeration of them, by specifying the powers excepted from the general definition; they might have been altogether silent on the subject, leaving these necessary and proper powers to construction and inference.
Had the convention taken the first method of adopting the second article of Confederation, it is evident that the new Congress would be continually exposed, as their predecessors have been, to the alternative of construing the term "EXPRESSLY" with so much rigor, as to disarm the government of all real authority whatever, or with so much latitude as to destroy altogether the force of the restriction. It would be easy to show, if it were necessary, that no important power, delegated by the articles of Confederation, has been or can be executed by Congress, without recurring more or less to the doctrine of CONSTRUCTION or IMPLICATION. As the powers delegated under the new system are more extensive, the government which is to administer it would find itself still more distressed with the alternative of betraying the public interests by doing nothing, or of violating the Constitution by exercising powers indispensably necessary and proper, but, at the same time, not EXPRESSLY granted.
Had the convention attempted a positive enumeration of the powers necessary and proper for carrying their other powers into effect, the attempt would have involved a complete digest of laws on every subject to which the Constitution relates; accommodated too, not only to the existing state of things, but to all the possible changes which futurity may produce; for in every new application of a general power, the PARTICULAR POWERS, which are the means of attaining the OBJECT of the general power, must always necessarily vary with that object, and be often properly varied whilst the object remains the same.
Had they attempted to enumerate the particular powers or means not necessary or proper for carrying the general powers into execution, the task would have been no less chimerical; and would have been liable to this further objection, that every defect in the enumeration would have been equivalent to a positive grant of authority. If, to avoid this consequence, they had attempted a partial enumeration of the exceptions, and described the residue by the general terms, NOT NECESSARY OR PROPER, it must have happened that the enumeration would comprehend a few of the excepted powers only; that these would be such as would be least likely to be assumed or tolerated, because the enumeration would of course select such as would be least necessary or proper; and that the unnecessary and improper powers included in the residuum, would be less forcibly excepted, than if no partial enumeration had been made.
