In Auguste Chouteau's Heirs, Appellants v. The United States, the Supreme Court heard a case concerning land rights in Missouri. The appellants were heirs of Auguste Chouteau who had been granted a large tract of land by the Spanish government before it ceded control to the United States in 1803. When Missouri became part of the Union in 1821, Congress passed an act that allowed settlers to purchase up to 320 acres from any public lands within its borders at $1.25 per acre and receive title from the federal government for their purchases without paying additional fees or taxes on them. However, this law did not apply to those with prior grants such as Chouteau’s heirs; they were required to pay all applicable fees and taxes if they wished for their titles be recognized by US courts as valid claims over their property. In its decision, the court held that while Congress could pass laws affecting private property rights acquired under foreign governments prior to statehood so long as it was done fairly and equitably with just compensation paid out when necessary; however since no such payment was made here nor any other form of equitable relief provided for these claimants then there would be no recognition given by US courts towards these pre-existing titles until such time came about where proper compensation is made available or some other form of equitable relief is provided instead..

In Auguste Chouteau's Heirs, Appellants v. The United States, the Supreme Court was asked to decide whether or not a certain tract of land in Missouri belonged to the heirs of Auguste Chouteau. The majority opinion held that it did not belong to them because they had failed to prove their claim with sufficient evidence and thus could not establish title under Spanish law. However, Justice McLean dissented from this decision and argued that while there may have been some deficiencies in the proof offered by the appellants, those deficiencies were due largely to circumstances beyond their control rather than any fault on their part. Furthermore, he noted that even if all other requirements for establishing title were met, it would still be unjust for them to lose out simply because they lacked documentary evidence which was destroyed during a period of war and unrest when such documents were difficult if not impossible obtainable. Thus he concluded that justice demanded recognition of their claim despite any technical shortcomings in its presentation before court
