But was the Act of Maryland which taxed the Bank in conflict with the Act of Congress which established it? If so, must the State yield to Congress? In approaching this question Marshall again laid the basis for as sweeping a decision as possible. The terms in which the Maryland statute was couched indicated clearly that it was directed specifically against the Bank, and it might easily have been set aside on that ground. But Marshall went much further and laid down the principle that the instrumentalities of the National Government are never subject to taxation by the States in any form whatsoever, and for two reasons. In the first place, "those means are not given by the people of a particular State ... but by the people of all the States. They are given by all for the benefit of all," and owe their presence in the State not to the State's permission but to a higher authority. The State of Maryland therefore never had the power to tax the Bank in the first place. Yet waiving this theory, there was, in the second place, flat incompatibility between the Act of Maryland and the Act of Congress, not simply because of the specific operation of the former, but rather because of the implied claim which it made for state authority. "That the power to tax involves the power to destroy," Marshall continued; "that the power to destroy may defeat and render useless the power to create; that there is a plain repugnance in conferring on one government a power to control the constitutional measures of another, which other, with respect to those very measures is declared to be supreme over that which exerts the control, are propositions not to be denied." Nor indeed is the sovereignty of the State confined to taxation. "That is not the only mode in which it might be displayed. The question is in truth, a question of supremacy, and if the right of the States to tax the means employed by the General Government be conceded, the declaration that the Constitution and the laws made in pursuance thereof shall be supreme law of the land, is empty and unmeaning declamation.... We are unanimously of opinion," concluded the Chief Justice, "that the law ... of Maryland, imposing a tax on the Bank of the United States is unconstitutional and void."
