Joseph Story, Commentaries on the Constitution 3:§§ 1900--19011833
§ 1900. This amendment is a mere affirmation of what, upon any just reasoning, is a necessary rule of interpreting the constitution. Being an instrument of limited and enumerated powers, it follows irresistibly, that what is not conferred, is withheld, and belongs to the state authorities, if invested by their constitutions of government respectively in them; and if not so invested, it is retained BY THE PEOPLE, as a part of their residuary sovereignty. When this amendment was before congress, a proposition was moved, to insert the word "expressly" before "delegated," so as to read "the powers not expressly delegated to the United States by the constitution," &c. On that occasion it was remarked, that it is impossible to confine a government to the exercise of express powers. There must necessarily be admitted powers by implication, unless the constitution descended to the most minute details. It is a general principle, that all corporate bodies possess all powers incident to a corporate capacity, without being absolutely expressed. The motion was accordingly negatived. Indeed, one of the great defects of the confederation was, (as we have already seen,) that it contained a clause, prohibiting the exercise of any power, jurisdiction, or right, not expressly delegated. The consequence was, that congress were crippled at every step of their progress; and were often compelled by the very necessities of the times to usurp powers, which they did not constitutionally possess; and thus, in effect, to break down all the great barriers against tyranny and oppression.
§ 1901. It is plain, therefore, that it could not have been the intention of the framers of this amendment to give it effect, as an abridgment of any of the powers granted under the constitution, whether they are express or implied, direct or incidental. Its sole design is to exclude any interpretation, by which other powers should be assumed beyond those, which are granted. All that are granted in the original instrument, whether express or implied, whether direct or incidental, are left in their original state. All powers not delegated, (not all powers not expressly delegated,) and not prohibited, are reserved. The attempts, then, which have been made from time to time, to force upon this language an abridging, or restrictive influence, are utterly unfounded in any just rules of interpreting the words, or the sense of the instrument. Stripped of the ingenious disguises, in which they are clothed, they are neither more nor less, than attempts to foist into the text the word "expressly;" to qualify, what is general, and obscure, what is clear, and defined. They make the sense of the passage bend to the wishes and prejudices of the interpreter; and employ criticism to support a theory, and not to guide it. One should suppose, if the history of the human mind did not furnish abundant proof to the contrary, that no reasonable man would contend for an interpretation founded neither in the letter, nor in the spirit of an instrument. Where is controversy to end, if we desert both the letter and the spirit? What is to become of constitutions of government, if they are to rest, not upon the plain import of their words, but upon conjectural enlargements and restrictions, to suit the temporary passions and interests of the day? Let us never forget, that our constitutions of government are solemn instruments, addressed to the common sense of the people and designed to fix, and perpetuate their rights and their liberties. They are not to be frittered away to please the demagogues of the day. They are not to be violated to gratify the ambition of political leaders. They are to speak in the same voice now, and for ever. They are of no man's private interpretation. They are ordained by the will of the people; and can be changed only by the sovereign command of the people.
