Joseph Story’s Commentaries on the Constitution, Volume 2, § 842
§ 842. [sic] These are all the powers and privileges, which are expressly vested in each house of congress by the constitution. What further powers and privileges they incidentally possess has been a question much discussed, and may hereafter be open, as new cases arise, to still further discussion. It is remarkable, that no power is conferred to punish for any contempts committed against either house; and yet it is obvious, that, unless such a power, to some extent, exists by implication, it is utterly impossible for either house to perform its constitutional functions. For instance, how is either house to conduct its own deliberations, if it may not keep out, or expel intruders? If it may not require and enforce upon strangers silence and decorum in its presence? If it may not enable its own members to have free ingress, egress, and regress to its own hall of legislation? And if the power exists, by implication, to require the duty, it is wholly nugatory, unless it draws after it the incidental authority to compel obedience, and to punish violations of it. It has been suggested by a learned commentator, quoting the language of Lord Bacon, that, as exception strengthens the force of a law in cases not excepted, so enumeration weakens it in cases not enumerated; and hence he deduces the conclusion, that, as the power to punish contempts is not among those enumerated, as belonging to either house, it does not exist. Now, however wise or correct the maxim of Lord Bacon is in a general sense, as a means of interpretation, it is not the sole rule. It is no more true, than another maxim of a directly opposite character, that where the end is required, the means are, by implication, given. Congress are required to exercise the powers of legislation and deliberation. The safety of the rights of the nation require this; and yet, because it is not expressly said, that congress shall possess the appropriate means to accomplish this end, the means are denied, and the end may be defeated. Does not this show, that rules of interpretation, however correct in a general sense, must admit of many qualifications and modifications in their application to the actual business of human life and human laws? Men do not frame constitutions of government to suspend its vital interests, and powers, and duties, upon metaphysical doubts, or ingenious refinements. Such instruments must be construed reasonably, and fairly, according to the scope of their purposes, and to give them effect and operation, not to cripple and destroy them. They must be construed according to the common sense applied to instruments of a like nature; and in furtherance of the fundamental objects proposed to be attained; and according to the known practice and incidents of bodies of a like nature.
