_First._ That the free native-born citizens of each State are citizens of the United States. _Second._ That as free colored persons born within some of the States are citizens of those States, such persons are also citizens of the United States. _Third._ That every such citizen, residing in any State, has the right to sue and is liable to be sued in the Federal courts, as a citizen of that State in which he resides. _Fourth._ That as the plea to the jurisdiction in this case shows no facts, except that the plaintiff was of African descent, and his ancestors were sold as slaves, and as these facts are not inconsistent with his citizenship of the United States, and his residence in the State of Missouri, the plea to the jurisdiction was bad, and the judgment of the Circuit Court overruling it was correct. I dissent, therefore, from that part of the opinion of the majority of the court, in which it is held that a person of African descent cannot be a citizen of the United States; and I regret I must go further, and dissent both from what I deem their assumption of authority to examine the constitutionality of the act of Congress commonly called the Missouri compromise act, and the grounds and conclusions announced in their opinion. Having first decided that they were bound to consider the sufficiency of the plea to the jurisdiction of the Circuit Court, and having decided that this plea showed that the Circuit Court had not jurisdiction, and consequently that this is a case to which the judicial power of the United States does not extend, they have gone on to examine the merits of the case as they appeared on the trial before the court and jury, on the issues joined on the pleas in bar, and so have reached the question of the power of Congress to pass the act of 1820. On so grave a subject as this, I feel obliged to say that, in my opinion, such an exertion of judicial power transcends the limits of the authority of the court, as described by its repeated decisions, and, as I understand, acknowledged in this opinion of the majority of the court.
