The U.S. Supreme Court case Bank of Minden et al. v. Clement, Administratrix of Clement in 1920 revolved around a dispute over the validity and enforceability of a promissory note issued by the deceased Mr. Clement to the Bank of Minden before his death. The bank sought repayment from Mrs.Clement as administratrix (executor) of her husband's estate, but she contested this on grounds that Louisiana state law did not recognize such notes unless they were specifically endorsed or transferred through an act known as 'novation'. The court ruled in favor of Mrs.Clement, stating that under Louisiana law, obligations like these cannot be enforced after one's death unless there is clear evidence showing intent for them to survive post-mortem - which was lacking in this case.

In the dissenting opinion for Bank of Minden et al. v. Clement, it was argued that the majority's decision to uphold a Louisiana law requiring banks to pay interest on deposits left in their care for more than one year was incorrect. The dissenting justices believed this ruling violated the contract clause of the U.S Constitution by interfering with pre-existing contracts between banks and depositors which did not stipulate any such obligation. They also contended that this law imposed an unfair burden on interstate commerce as out-of-state banks were not subject to these same requirements, thus giving them a competitive advantage over Louisiana-based institutions. Furthermore, they expressed concern about potential negative impacts on banking stability if all states enacted similar legislation forcing banks to pay interest on deposits regardless of agreed terms.
