There seems to be no substantial difference between my brethren and myself as to the purpose of Congress; for, they say that the essence of the law is, not to declare broadly that all persons shall be entitled to the full and equal enjoyment of the accommodations, advantages, facilities and privileges of inns, public conveyances and theatres; but that such enjoyment shall not be subject to conditions applicable only to citizens of a particular race or color, or who had been in a previous condition of servitude. The effect of the statute, the court says, is, that colored citizens, whether formerly slaves or not, and citizens of other races, shall have the same accommodations and privileges in all inns, public conveyances and places of amusement as are enjoyed by white persons; and vice versa.

The court adjudges, I think erroneously, that Congress is without power, under either the Thirteenth or Fourteenth Amendments, to establish such regulations, and that the first and second sections of the statute are, in all their parts, unconstitutional and void.

Whether the legislative department of the government has transcended the limits of its constitutional powers, “is at all times,” said the court in Fletcher v. Peck, 6 Cr. 128, “a question of much delicacy, which ought seldom, if ever, to be decided in the affirmative, in a doubtful case.... The opposition between the Constitution and the law should be such that the judge feels a clear and strong conviction of their incompatibility with each other.” More recently in Sinking Fund Cases, 99 U. S., 718, we said: “It is our duty when required in the regular course of judicial proceedings, to declare an Act of Congress void if not within the legislative power of the United States; but this declaration should never be made except in a clear case. Every possible presumption is in favor of the validity of a statute, and this continues until the contrary is shown beyond a rational doubt. One branch of the government cannot encroach on the domain of another without danger. The safety of our institutions depends in no small degree on a strict observance of this salutary rule.”

Before considering the language and scope of these amendments, it will be proper to recall the relations subsisting, prior to their adoption, between the national government and the institution of slavery, as indicated by the provisions of the Constitution, the legislation of Congress, and the decisions of this court. In this mode we may obtain keys with which to open the mind of the people, and discover the thought intended to be expressed.

In section 2 of article IV. of the Constitution it was provided that “no person held to service or labor in one State, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up on claim of the party to whom such service or labor may be due.” Under authority of this clause Congress passed the Fugitive Slave Law of 1793, establishing a mode for the recovery of fugitive slaves, and prescribing a penalty against any person who should knowingly and willingly obstruct or hinder the master, his agent, or attorney, in seizing, and recovering the fugitive, or who should rescue the fugitive from him, or who should harbor or conceal the slave after notice that he was a fugitive.

In Prigg v. Commonwealth of Pennsylvania, 16 Pet. 539, this court had occasion to define the powers and duties of Congress in reference to fugitives from labor. Speaking by Mr. Justice Story, it laid down these propositions:

That a clause of the Constitution conferring a right should not be so construed as to make it shadowy, or unsubstantial, or leave the citizen without a remedial power adequate for its protection, when another construction equally accordant with the words and the sense in which they were used, would enforce and protect the right granted:

That Congress is not restricted to legislation for the execution of its expressly granted powers; but for the protection of rights guaranteed by the Constitution, may employ such means, not prohibited, as are necessary and proper, or such as are appropriate, to attain the ends proposed:

That the Constitution recognized the master’s right of property in his fugitive slave, and, as incidental thereto, the right of seizing and recovering him, regardless of any State law, or regulation, or local custom whatsoever; and,

That the right of the master to have his slave, thus escaping, delivered up on claim, being guaranteed by the Constitution, the fair implication was that the national government was clothed with appropriate authority and functions to enforce it.
