In the case of Pell et al. v. McCabe et al., 1919, the United States Supreme Court dealt with a dispute over land ownership in Oklahoma between two parties: one group who had purchased lots from an individual named Charles Page and another group who claimed rights to the same land through inheritance from original allottees under tribal law. The court ruled that those who bought their lots from Page did not have valid claims to ownership because Page himself never legally owned it; he merely held it in trust for Native American children as part of a government program designed to assimilate them into white society by providing them with homes and education funded by oil revenues generated on their lands. This ruling affirmed that federal policy at this time prioritized maintaining tribal sovereignty and property rights over promoting assimilation efforts.

The dissenting opinion in the case of Pell et al. v. McCabe et al., argued that the majority's decision was a misinterpretation of the law and an overreach of judicial power. The dissent believed that it was not within their jurisdiction to decide on matters related to property rights, especially when such decisions could potentially disrupt established legal principles and practices. They contended that by ruling in favor of McCabe, they were effectively disregarding existing laws regarding land ownership and inheritance rights, which could have far-reaching implications for future cases involving similar issues. Furthermore, they expressed concern about how this ruling might affect other areas of law where clear boundaries between different types of property are essential for maintaining order and fairness in society.
