In the case of Louis D. Gamache, Samuel and Leonore Gamache, by Guardian Wilson Primm, Louis Primm, John Cavenden and Abby P. True v Francois X. Piquignot and the Inhabitants of the Town of Carondelet, plaintiffs argued that they were entitled to a certain tract of land in St. Louis County due to an 1805 Spanish grant from Spain while defendants claimed it was part of their town limits as established by Congress in 1812 when Missouri became a state. The Supreme Court held that although there had been some confusion regarding ownership over time due to conflicting grants from both Spain and Congress for this particular piece of property, ultimately it belonged to the plaintiff based on their original Spanish grant which predated any other claims made against it since its validity could not be denied or superseded without violating international law between nations at that time period.

In the dissenting opinion of this case, Justice McLean argued that the plaintiffs had a right to bring their claim against Piquignot and the inhabitants of Carondelet. He noted that they were seeking damages for an injury done to them by those defendants, which was not in dispute. Furthermore, he stated that it was clear from Missouri law that such claims could be brought before any court with jurisdiction over the parties involved. Therefore, he concluded that there was no legal basis for dismissing the suit as moot or otherwise denying justice to these plaintiffs.
