The U.S. Supreme Court case James-Dickinson Farm Mortgage Company et al. v. Harry (1926) revolved around the issue of land ownership and mortgage payments in relation to Native American tribal lands. The plaintiff, James-Dickinson Farm Mortgage Company, had provided a loan to the defendant, a member of an Indian tribe named Harry who used his allotted tribal land as collateral for the loan. When Harry defaulted on his mortgage payments, the company sought to foreclose on the property but was met with legal resistance due to federal laws protecting Native American lands from seizure or foreclosure by non-tribal entities without congressional approval. In its decision, the Supreme Court ruled that while individual members of tribes could take out loans using their allotments as collateral under certain circumstances outlined in previous legislation such as Dawes Act (1887), they were still protected from foreclosure by non-tribal entities under other existing federal laws designed specifically for this purpose. This ruling upheld protections for Native Americans against loss of their allocated lands through financial transactions with non-Native individuals or companies and reinforced Congress's authority over these matters.

In the dissenting opinion for James-Dickinson Farm Mortgage Company et al. v. Harry, Justice Holmes disagreed with the majority's decision to uphold a state law that allowed mortgagors to extend their redemption period during an economic crisis. He argued that this ruling violated contract rights protected by the Constitution and was essentially a form of government overreach into private agreements between parties. Furthermore, he contended that such laws could potentially discourage future lending due to increased uncertainty and risk for lenders, thereby exacerbating financial crises rather than alleviating them.
