Auguste de Montault, Augustine Rene Therese Montault by her next friend Louis Montault and William Roger de la Chouquais, husband of the said Augustine, Louis Montault, Bernard Dautierre, Valerie Dautierre, Eleanor Dautierre by her next friend Louis Montualt and her husband Augustin Richard Adeline Dautierrre Virginie Dautiere by her next friend Louis Monatult and her husband Lewis Bouligny Fanny Dauteire Theodore Dauteire Pauline Dauteire by her next friend Lousi Monatult and hwer husbamd Samuel Logan (the appellants) appealed to the United States Supreme Court against The United States. This case involved a dispute over land in Louisiana that had been granted to them under Spanish rule prior to its cession to the US. The appellants argued that they were entitled to their property rights as established under Spanish law but this was rejected on appeal. Ultimately it was decided that since Louisiana had become part of the US after being acquired from France in 1803 then all laws relating to ownership would be subject those set out in US legislation rather than any previous foreign laws or regulations.

In the dissenting opinion of this US Supreme Court case, it was argued that the United States had no right to seize and sell property belonging to French citizens who were living in Louisiana when it became part of the United States. The appellants claimed that they should be protected by a treaty between France and the United States which guaranteed them their rights as foreign nationals. However, the majority opinion held that since these individuals were not naturalized citizens at the time of seizure, they did not have any legal standing or protection under US law. The dissenters disagreed with this ruling on grounds that such an interpretation would violate international treaties and deprive innocent people of their rightful property without due process. They also argued that if Congress intended for non-citizens to lose their rights upon annexation then there must be some explicit language in either a statute or treaty indicating so; otherwise, all existing agreements should remain valid until explicitly revoked by both parties involved.
