In the discussions upon the subject of legal tender the advocates of the measure do not agree as to the power in the constitution to which it shall be referred; some placing it upon the power to borrow money, some on the coining power, and some on what is termed a resulting power from the general purposes of the government; and these discussions have been accompanied by statements as to the effect of the measure, and the consequences which must have followed had it been rejected, and which will now occur if its validity be not sustained, which rest upon no solid foundation, and are not calculated to aid the judgment in coming to a just conclusion.
In what I have to say I shall endeavor to avoid any such general and loose statements, and shall direct myself to an inquiry into the nature of these powers to which the measure is referred, and the relation of the measure to them.
Now if congress can, by its legislative declaration, make the notes of the United States a legal tender in payment of private debts—that is, can make them receivable against the will of the creditor in satisfaction of debts due to him by third parties—its power in this respect is not derived from its power to borrow money, under which the notes were issued. That power is not different in its nature or essential incidents from the power to borrow possessed by individuals, and is not to receive a larger definition. Nor is it different from the power often granted to public and private corporations. The grant, it is true, is usually accompanied in these latter cases with limitations as to the amount to be borrowed, and a designation of the objects to which the money shall be applied—limitations which in no respect affect the nature of the power. The terms "power to borrow money" have the same meaning in all these cases, and not one meaning when used by individuals, another when granted to corporations, and still a different one when possessed by congress. They mean only a power to contract for a loan of money upon considerations to be agreed between the parties. The amount of the loan, the time of repayment, the interest it shall bear, and the form in which the obligation shall be expressed are simply matters of arrangement between the parties. They concern no one else. It is no part or incident of a contract of this character that the rights or interests of third parties, strangers to the matter, shall be in any respect affected. The transaction is completed when the lender has parted with his money, and the borrower has given his promise of repayment at the time, and in the manner, and with the securities stipulated between them.
As an inducement to the loan, and security for its repayment, the borrower may of course pledge such property or revenues, and annex to his promises such rights and privileges as he may possess. His stipulations in this respect are necessarily limited to his own property, rights, and privileges, and cannot extend to those of other persons.
Now, whether a borrower—be the borrower an individual, a corporation, or the government—can annex to the bonds, notes, or other evidences of debt given for the money borrowed, any quality by which they will serve as a means of satisfying the contracts of other parties, must necessarily depend upon the question whether the borrower possesses any right to interfere with such contracts, and determine how they shall be satisfied. The right of the borrower in this respect rests upon no different foundation than the right to interfere with any other property of third parties. And if it will not be contended, as I think I may assume it will not be, that the borrower possesses any right, in order to make a loan, to interfere with the tangible and visible property of third parties, I do not perceive how it can be contended that he has any right to interfere with their property when it exists in the form of contracts. A large part of the property of every commercial people exists in that form, and the principle which excludes a stranger from meddling with another's property which is visible and tangible, equally excludes him from meddling with it when existing in the form of contracts.
That an individual or corporation borrowing possesses no power to annex to his evidences of indebtedness any quality by which the holder will be enabled to change his contracts with third parties, strangers to the loan, is admitted; but it is contended that congress possesses such power because, in addition to the express power to borrow money, there is a clause in the constitution which authorizes congress to make all laws "necessary and proper" for the execution of the powers enumerated. This clause neither augments nor diminishes the expressly designated powers. It only states in terms what congress would equally have had the right to do without its insertion in the constitution. It is a general principle that a power to do a particular act includes the power to adopt all the ordinary and appropriate means for its execution. "Had the constitution," says Hamilton, in the Federalist, speaking of this clause, "been silent on this head, there can be no doubt that all the particular powers requisite as a 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, that whenever the end is required the means are authorized; whenever a general power to do a thing is given, every particular power necessary for doing it is included.
The subsidiary power existing without the clause in question, its insertion in the constitution was no doubt intended, as observed by Mr. Hamilton, to prevent "all cavilling refinements" in those who might thereafter feel a disposition to curtail and evade the legitimate authorities of the Union; and also, I may add, to indicate the true sphere and limits of the implied powers.
But though the subsidiary power would have existed without this clause, there would have been the same perpetually recurring question as now, as to what laws are necessary and proper for the execution of the expressly enumerated powers.
The particular clause in question has at different times undergone elaborate discussions in congress, in cabinets, and in the courts. Its meaning was much debated in the first congress upon the proposition to incorporate a national bank, and afterwards in the cabinet of Washington, when that measure was presented for his approval. Mr. Jefferson, then secretary of state, and Mr. Hamilton, then secretary of the treasury, differed widely in their construction of the clause, and each gave his views in an elaborate opinion. Mr. Jefferson held that the word "necessary" restricted the power of congress to the use of those means, without which the grant would be nugatory, thus making necessary equivalent to indispensable.
Mr. Hamilton favored a more liberal, and in my judgment, a more just interpretation, and contended that the terms "necessary and proper" meant no more than that the measures adopted must have an obvious relation as a means to the end intended. "If the end," he said, "be clearly comprehended within any of the specified powers, and if the measure have an obvious relation to that end, and is not forbidden by any particular provision of the constitution, it may safely be deemed to come within the compass of the national authority." "There is also," he added, "this further criterion which may materially assist the decision: Does the proposed measure abridge a pre-existing right of any state, or of any individual? If it does not, there is a strong presumption in favor of its constitutionality; and slighter relations to any declared object may be permitted to turn the scale." From the criterion thus indicated it would seem that the distinguished statesman was of opinion that a measure which did interfere with a pre-existing right of a state or an individual would not be constitutional.
