Mr. Justice GRIER.
I concur in the opinion delivered by Mr. Justice Nelson on the questions discussed by him.
I also concur with the opinion of the court as delivered by the Chief Justice, that the act of Congress of 6th March, 1820, is unconstitutional and void; and that, assuming the facts as stated in the opinion, the plaintiff cannot sue as a citizen of Missouri in the courts of the United States. But, that the record shows a prima facie case of jurisdiction, requiring the court to decide all the questions properly arising in it; and as the decision of the pleas in bar shows that the plaintiff is a slave, and therefore not entitled to sue in a court of the United States, the form of the judgment is, of little importance; for, whether the judgment be affirmed or dismissed for want of jurisdiction, it is justified, by the decision of the court, and is the same in effect between the parties to the suit.
