"The legislative powers vested in Congress are specified and enumerated in the eighth section of the first article of the Constitution, and it does not appear that the power proposed to be exercised by the bill is among the enumerated powers, or that it falls by any just interpretation with the power to make laws necessary and proper for carrying into execution those or other powers vested by the Constitution in the Government of the United States."The power to regulate commerce among the several States" can not include a power to construct roads and canals, and to improve the navigation of water courses in order to facilitate, promote, and secure such commerce with a latitude of construction departing from the ordinary import of the terms strengthened by the known inconveniences which doubtless led to the grant of this remedial power to Congress.
To refer the power in question to the clause "to provide for common defense and general welfare" would be contrary to the established and consistent rules of interpretation, as rendering the special and careful enumeration of powers which follow the clause nugatory and improper. Such a view of the Constitution would have the effect of giving to Congress a general power of legislation instead of the defined and limited one hitherto understood to belong to them, the terms "common defense and general welfare" embracing every object and act within the purview of a legislative trust. It would have the effect of subjecting both the Constitution and laws of the several States in all cases not specifically exempted to be superseded by laws of Congress, it being expressly declared "that the Constitution of the United States and laws made in pursuance thereof shall be the supreme law of the land, and the judges of every state shall be bound thereby, anything in the constitution or laws of any State to the contrary notwithstanding." Such a view of the Constitution, finally, would have the effect of excluding the judicial authority of the United States from its participation in guarding the boundary between the legislative powers of the General and the State Governments, inasmuch as questions relating to the general welfare, being questions of policy and expediency, are unsusceptible of judicial cognizance and decision."
... Some, who have not denied the necessity of the power of taxation, have grounded a very fierce attack against the Constitution, on the language in which it is defined. It has been urged and echoed, that the power "to lay and collect taxes, duties, imposts, and excises, to pay the debts, and provide for the common defense and general welfare of the United States,'' amounts to an unlimited commission to exercise every power which may be alleged to be necessary for the common defense or general welfare. No stronger proof could be given of the distress under which these writers labor for objections, than their stooping to such a misconstruction. Had no other enumeration or definition of the powers of the Congress been found in the Constitution, than the general expressions just cited, the authors of the objection might have had some color for it; though it would have been difficult to find a reason for so awkward a form of describing an authority to legislate in all possible cases. A power to destroy the freedom of the press, the trial by jury, or even to regulate the course of descents, or the forms of conveyances, must be very singularly expressed by the terms "to raise money for the general welfare.ML/NJBut what color can the objection have, when a specification of the objects alluded to by these general terms immediately follows, and is not even separated by a longer pause than a semicolon? If the different parts of the same instrument ought to be so expounded, as to give meaning to every part which will bear it, shall one part of the same sentence be excluded altogether from a share in the meaning; and shall the more doubtful and indefinite terms be retained in their full extent, and the clear and precise expressions be denied any signification whatsoever? For what purpose could the enumeration of particular powers be inserted, if these and all others were meant to be included in the preceding general power? Nothing is more natural nor common than first to use a general phrase, and then to explain and qualify it by a recital of particulars. But the idea of an enumeration of particulars which neither explain nor qualify the general meaning, and can have no other effect than to confound and mislead, is an absurdity, which, as we are reduced to the dilemma of charging either on the authors of the objection or on the authors of the Constitution, we must take the liberty of supposing, had not its origin with the latter. The objection here is the more extraordinary, as it appears that the language used by the convention is a copy from the articles of Confederation. The objects of the Union among the States, as described in article third, are "their common defense, security of their liberties, and mutual and general welfare. '' The terms of article eighth are still more identical: "All charges of war and all other expenses that shall be incurred for the common defense or general welfare, and allowed by the United States in Congress, shall be defrayed out of a common treasury,'' etc. A similar language again occurs in article ninth. Construe either of these articles by the rules which would justify the construction put on the new Constitution, and they vest in the existing Congress a power to legislate in all cases whatsoever.
But what would have been thought of that assembly, if, attaching themselves to these general expressions, and disregarding the specifications which ascertain and limit their import, they had exercised an unlimited power of providing for the common defense and general welfare? I appeal to the objectors themselves, whether they would in that case have employed the same reasoning in justification of Congress as they now make use of against the convention. How difficult it is for error to escape its own condemnation!
