1. The Constitution (section 8) confers on Congress certain essential powers: as, to collect taxes, without which no government can be supported.
  2. The Constitution (same section) authorizes Congress to "make all laws that shall be necessary and proper for carrying into execution" these powers.
  3. If Congress fail to carry into execution these powers, the Government is set at nought, and anarchy ensues.
  4. An insurrection, extending over eleven of the States comprising the Union, now prevails.
  5. Because of that insurrection, the essential powers granted to Congress by the Constitution cannot be carried into execution in these eleven States.
  6. Because of the resistance offered by these insurrectionary States to constitutional powers, it becomes the duty of Congress to pass all laws that are necessary and proper to enforce these powers.

All this will be conceded; but a question remains. Who is to judge what laws are necessary and proper to carry into execution the powers, expressly granted by the Constitution, which are thus obstructed and defeated?

This question has been determined by the highest legal tribunal of the United States, speaking by the mouth of one who will be acknowledged to have been her most distinguished presiding officer.

In the well-known case of McCulloch against the State of Maryland,[8] Chief-Justice Marshall delivered the decision of the Supreme Court; and by that decision the following principles were established:—

  1. The construction of the words "necessary and proper" in the above connection. The Chief-Justice says,—
  2. "The term 'necessary' does not import an absolute physical necessity, so strong that one thing to which another may be termed necessary cannot exist without that other."
  3. As to the degree of the necessity which renders constitutional a law framed to carry a constitutional power into execution, the rule by this decision is,—
  4. "If a certain means to carry into effect any of the powers expressly given by the Constitution to the Government of the Union be an appropriate measure, not prohibited by the Constitution, the degree of its necessity is a question of legislative discretion, not of judicial cognizance."
  5. But still more explicitly is the question answered, who is to be the judge of the appropriateness and necessity of the means to be employed, thus:—
  6. "The Government which has a right to do an act, and has imposed upon it the duty of performing that act, must, according to the dictates of reason, be allowed to select the means."

Thus, then, the matter stands. The powers to lay and collect taxes, to exercise authority over forts and arsenals of the United States, to suppress insurrection, and various others equally essential, are expressly given by the Constitution to Congress. It is the right and duty of Congress to carry these powers into effect. In case of obstruction or defeat of existing laws framed to that intent, it is the right and duty of Congress to select such means and pass such additional laws as may be necessary and proper to overcome such obstruction and enforce obedience to such laws. In the selection of the means to effect this constitutional object, Congress is the sole judge of their propriety or necessity. These means must not be prohibited by the Constitution; but whether they are the most prudent or the most effectual means, or in what degree they are necessary, are matters over which the Supreme Court has no jurisdiction. As Chief-Justice Marshall has elsewhere in this decision expressed it, for the Supreme Court to undertake to inquire into the degree of their necessity "would be to pass the line which circumscribes the judicial department and to tread on legislative ground."

There must, of course, be congruity or relevancy between the power to be enforced and the means proposed to enforce it. While Congress is to judge the degree of necessity or propriety of these means, they must not be such as to be devoid of obvious connection with the object to be attained.

In this case, the object to be attained is the enforcement, in the insurrectionary States, of laws without which no government can exist, and the suppression in these States of an insurrection of which the object is the dismemberment of the Union.

But these laws are resisted, and this insurrection prevails, in those States, and in those States only, in which the life-long claims to the service or labor of persons of African descent are held under State laws. In States where slaves are comparatively few, as in Delaware, Maryland, Missouri, disaffection only prevails; while in States where the number of slaves approaches or exceeds that of whites, as in South Carolina, Alabama, Georgia, insurrection against lawful authority is flagrant and outspoken: the insurrectionary acts of these States being avowedly based on the allegation that Slavery is not safe under the present constitutionally elected President, and that its permanent preservation can be insured by the disruption of the national unity alone.[9]

All this is matter of history. And there would be as much propriety in denying the connection between the sun and the light of day, as that between Slavery and the Rebellion.
