Upon this record, it is apparent that this is not a controversy between citizens of different States; and that the plaintiff, at no period of the life which has been submitted to the view of the court, has had a capacity to maintain a suit in the courts of the United States. And in so far as the argument of the Chief Justice upon the plea in abatement has a reference to the plaintiff or his family, in any of the conditions or circumstances of their lives, as presented in the evidence, I concur in that portion of his opinion. I concur in the judgment which expresses the conclusion that the Circuit Court should not have rendered a general judgment. The capacity of the plaintiff to sue is involved in the pleas in bar, and the verdict of the jury discloses an incapacity under the Constitution. Under the Constitution of the United States, his is an incapacity to sue in their courts, while, by the laws of Missouri, the operation of the verdict would be more extensive. I think it a safe conclusion to enforce the lesser disability imposed by the Constitution of the United States, and leave to the plaintiff all his rights in Missouri. I think the judgment should be affirmed, on the ground that the Circuit Court had no jurisdiction, or that the case should be reversed and remanded, that the suit may be dismissed. * * * * * Mr. Justice CATRON. The defendant pleaded to the jurisdiction of the Circuit Court, that the plaintiff was a negro of African blood; the descendant of Africans, who had been imported and sold in this country as slaves, and thus had no capacity as a citizen of Missouri to maintain a suit in the Circuit Court. The court sustained a demurrer to this plea, and a trial was had upon the pleas, of the general issue, and also that the plaintiff and his family were slaves, belonging to the defendant. In this trial, a verdict was given for the defendant. The judgment of the Circuit Court upon the plea in abatement is not open, in my opinion, to examination in this court upon the plaintiff's writ. The judgment was given for him conformably to the prayer of his demurrer. He cannot assign an error in such a judgment. (Tidd's Pr., 1163; 2 Williams's Saund., 46 a; 2 Iredell N.C., 87; 2 W. and S., 391.) Nor does the fact that the judgment was given on a plea to the jurisdiction, avoid the application of this rule.
