Thomas Jefferson on the constitutionality of the proposed national bank [Edited Excerpt]

I consider the foundation of the Constitution as laid on this ground: That "all powers not delegated to the United States, by the Constitution, nor prohibited by it to the States, are reserved to the States or to the people." [Amendment X.] To take a single step beyond the boundaries thus specially drawn around the powers of Congress is to take possession of a boundless field of power, no longer susceptible of any definition.

The incorporation of a bank, and the powers assumed by this bill, have not, in my opinion, been delegated to the United States, by the Constitution.

The incorporation of a bank, and the powers assumed by this bill, have not, in my opinion, been delegated to the United States, by the Constitution.

Nor are they within either of the general phrases, which are the two following: . . .

The second general phrase is, "to make all laws necessary and proper for carrying into execution the enumerated powers." But they can all be carried into execution without a bank. A bank therefore is not necessary, and consequently not authorized by this phrase.

If has been urged that a bank will give great facility or convenience in the collection of taxes, Suppose this were true: yet the Constitution allows only the means which are "necessary," not those which are merely "convenient" for effecting the enumerated powers. If such a latitude of construction be allowed to this phrase as to give any non-enumerated power, it will go to everyone, for there is not one which ingenuity may not torture into a convenience in some instance or other, to some one of so long a list of enumerated powers. It would swallow up all the delegated powers, and reduce the whole to one power, as before observed. Therefore it was that the Constitution restrained them to the necessary means, that is to say, to those means without which the grant of power would be nugatory
