“ It will be observed that this was a suit by a citizen. There was no suggestion that the statute went to the jurisdiction of the court. Obviously it did not. Indeed, the suit was brought in the United States circuit court. The statute made no discrimination in the right to come into court, according to the character of the plaintiff or of the cause of action, but attempted to create a defense against a plaintiff assumed to have a right to come into court and to invoke the jurisdiction. But when the plaintiff was in court, and exhibited his judgment, it was too late for the state to interfere. ”

“ If the state does provide a court to which its own citizens may resort in a certain class of cases, it may be that citizens of other states of the Union also would have a right to resort to it in cases of the same class. ”

“ The general power of a state to restrict the right of a foreign corporation to sue in its courts is assumed in Bank of Augusta v. Earle, 13 Pet. 519, 589-591, 10 L. ed. 274, 308, 309. As to discrimination against nonresidents, see Chemung Canal Bank v. Lowery, 93 U.S. 72, 23 L. ed. 806.
The plaintiff lays great stress upon Christmas v. Russell, 5 Wall. 290, 18 L. ed. 475. In that case suit was brought in Mississippi on a Kentucky judgment against a citizen of Mississippi upon a promissory note made in Mississippi, and payable in New Orleans. ”
