The case of Rhodes _v._ Bell (2 Howard, 307; 15 Curtis, 152) involved the main principle in the case before us. A person residing in Washington city purchased a slave in Alexandria, and brought him to Washington. Washington continued under the law of Maryland, Alexandria under the law of Virginia. The act of Maryland of November, 1796, (2 Maxcy's Laws, 351,) declared any one who shall bring any negro, mulatto or other slave, into Maryland, such slave should be free. The above slave, by reason of his being brought into Washington city, was declared by this court to be free. This, it appears to me, is a much stronger case against the slave than the facts in the case of Scott. In Bush _v._ White, (3 Monroe, 104,) the court say: "That the ordinance was paramount to the Territorial laws, and restrained the legislative power there as effectually as a Constitution in an organized State. It was a public act of the Legislature of the Union, and a part of the supreme law of the land; and, as such, this court is as much bound to take notice of it as it can be of any other law." In the case of Rankin _v._ Lydia, before cited, Judge Mills, speaking for the Court of Appeals of Kentucky, says: "If, by the positive provision in our code, we can and must hold our slaves in the one case, and statutory provisions equally positive decide against that right in the other, and liberate the slave, he must, by an authority equally imperious, be declared free. Every argument which supports the right of the master on one side, based upon the force of written law, must be equally conclusive in favor of the slave, when he can point out in the statute the clause which secures his freedom." And he further said: "Free people of color in all the States are, it is believed, quasi citizens, or, at least, denizens. Although none of the States may allow them the privilege of office and suffrage, yet all other civil and conventional rights are secured to them; at least, such rights were evidently secured to them by the ordinance in question for the government of Indiana. If these rights are vested in that or any other portion of the United States, can it be compatible with the spirit of our confederated Government to deny their existence in any other part? Is there less comity existing between State and State, or State and Territory, than exists between the despotic Governments of Europe?" These are the words of a learned and great judge, born and educated in a slave State. I now come to inquire, under the sixth and last head, "whether the decisions of the Supreme Court of Missouri, on the question before us, are binding on this court."
