the necessary/sufficient distinction in McCulloch v. MD Forum

[dbrddr]

..has broken down.

"The word "necessary" is considered as controlling the whole sentence, and as limiting the right to pass laws for the execution of the granted powers, to such as are indispensable, and without which the power would be nugatory. That it excludes the choice of means, and leaves to Congress in each case, that only which is most direct and simple."

"Is it true, that this is the sense in which the word "necessary" is always used? Does it always import an absolute physical necessity, so strong, that one thing, to which another may be termed necessary, cannot exist without that other? We think it does not. If reference be had to its use, in the common affairs of the world, or in approved authors, we find that it frequently imports no more than that one thing is convenient, or useful, or essential to another. To employ the means necessary to an end, is generally understood as employing any means calculated to produce the end, and not as being confined to those single means, without which the end would be entirely unattainable. Such is the character of human language, that no word conveys to the mind, in all situations, one single definite idea; and nothing is more common than to use words in a figurative sense. Almost all compositions contain words, which, taken in their rigorous sense, would convey a meaning different from that which is obviously intended. It is essential to just construction, that many words which import something excessive, should be understood in a more mitigated sense--in that sense which common usage justifies. The word "necessary" is of this description. It has not a fixed character peculiar to itself. It admits of all degrees of comparison; and is often connected with other words, which increase or diminish the impression the mind receives of the urgency it imports. A thing may be necessary, very necessary, absolutely or indispensably necessary. To no mind would the same idea be conveyed, by these several phrases. This comment on the word is well illustrated, by the passage cited at the bar, from the 10th section of the 1st article of the Constitution. It is, we think, impossible to compare the sentence which prohibits a State from laying "imposts, or duties on imports or exports, except what may be absolutely necessary for executing its inspection laws," with that which authorizes Congress "to make all laws which shall be necessary and proper for carrying into execution" the powers of the general government, without feeling a conviction that the convention understood itself to change materially the meaning of the word "necessary," by prefixing the word "absolutely." This word, then, like others, is used in various senses; and, in its construction, the subject, the context, the intention of the person using them, are all to be taken into view."
