Third. The laws of the United States, in operation in the Territory of Wisconsin at the time of the plaintiff's residence there, did act directly on the status of the plaintiff, and change his status to that of a free man.
Fourth. The plaintiff and his wife were capable of contracting, and, with the consent of Dr. Emerson, did contract a marriage in that Territory, valid under its laws; and the validity of this marriage cannot be questioned in Missouri, save by showing that it was in fraud of the laws of that State, or of some right derived from them; which cannot be shown in this case, because the master consented to it.
Fifth. That the consent of the master that his slave, residing in a country which does not tolerate slavery, may enter into a lawful contract of marriage, attended with the civil rights and duties which belong to that condition, is an effectual act of emancipation. And the law does not enable Dr. Emerson, or any one claiming under him, to assert a title to the married persons as slaves, and thus destroy the obligation of the contract of marriage, and bastardize their issue, and reduce them to slavery.
But it is insisted that the Supreme Court of Missouri has settled this case by its decision in Scott v. Emerson, (15 Missouri Reports, 576;) and that this decision is in conformity with the weight of authority elsewhere, and with sound principles. If the Supreme Court of Missouri had placed its decision on the ground that it appeared Dr. Emerson never became domiciled in the Territory and so its laws could not rightfully operate on him and his slave; and the facts that he went there to reside indefinitely, as an officer of the United States, and that the plaintiff was lawfully married there, with Dr. Emerson's consent, were left out of view, the decision would find support in other cases, and I might not be prepared to deny its correctness. But the decision is not rested on this ground. The domicil of Dr. Emerson in that Territory is not questioned in that decision; and it is placed on a broad denial of the operation, in Missouri, of the law of any foreign State or country upon the status of a slave, going with his master from Missouri into such foreign State or country, even though they went thither to become, and actually became, permanent inhabitants of such foreign State or country, the laws whereof acted directly on the status of the slave, and changed his status to that of a freeman.
To the correctness of such a decision I cannot assent. In my judgment, the opinion of the majority of the court in that case is in conflict with its previous decisions, with a great weight of judicial authority in other slaveholding States, and with fundamental principles of private international law. Mr. Chief Justice Gamble, in his dissenting opinion in that case, said:
"I regard the question as conclusively settled by repeated adjudications of this court; and if I doubted or denied the propriety of those decisions, I would not feel myself any more at liberty to overturn them, than I would any other series of decisions by which the law upon any other question had been settled. There is with me nothing in the law of slavery which distinguishes it from the law on any other subject, or allows any more accommodation to the temporary excitements which have gathered around it.... But in the midst of all such excitement, it is proper that the judicial mind, calm and self-balanced, should adhere to principles established when there was no feeling to disturb the view of the legal questions upon which the rights of parties depend."
"In this State, it has been recognised from the beginning of the Government as a correct position in law, that the master who takes his slave to reside in a State or Territory where slavery is prohibited, thereby emancipates his slave." (Winney v. Whitesides, 1 Mo., 473; Le Grange v. Chouteau, 2 Mo., 20; Milley v. Smith, Ib., 36; Ralph v. Duncan, 3 Mo., 194; Julia v. McKinney, Ib., 270; Nat v. Ruddle, Ib., 400; Rachel v. Walker, 4 Mo., 350; Wilson v. Melvin, 592.)
Chief Justice Gamble has also examined the decisions of the courts of other States in which slavery is established, and finds them in accordance with these preceding decisions of the Supreme Court of Missouri to which he refers.
It would be a useless parade of learning for me to go over the ground which he has so fully and ably occupied.
But it is further insisted we are bound to follow this decision. I do not think so. In this case, it is to be determined what laws of the United States were in operation in the Territory of Wisconsin, and what was their effect on the status of the plaintiff. Could the plaintiff contract a lawful marriage there? Does any law of the State of Missouri impair the obligation of that contract of marriage, destroy his rights as a husband, bastardize the issue of the marriage, and reduce them to a state of slavery?
