In the 1890 case of Natal v. Louisiana, the U.S. Supreme Court dealt with a dispute over property rights and inheritance laws in Louisiana. The plaintiff, Natal, was an heir to a piece of land that had been sold by his father's estate to pay off debts after his death. However, he argued that under French law (which was applicable in certain parts of Louisiana at the time), he should have inherited half of his father's property directly upon his death and thus it could not be used to pay off these debts. The court ruled against him on two grounds: firstly because they found no evidence supporting this interpretation of French law; secondly because even if such a rule did exist under French law, it would not apply here as American common law principles were now dominant in all areas where there might previously have been some ambiguity or overlap between different legal systems. This decision is significant for its affirmation that American common-law rules supersede any remnants from previous colonial legal systems when dealing with matters related to real estate transactions and inheritances.

The dissenting opinion in the Natal v. Louisiana case argued that the majority's decision to uphold a Louisiana law prohibiting non-white individuals from serving on juries was fundamentally unjust and violated constitutional principles of equal protection under the law. The dissenters contended that this racial exclusion undermined the fairness and impartiality of jury trials, which are foundational elements of American jurisprudence. They also pointed out that such discriminatory practices were inconsistent with post-Civil War amendments designed to ensure full citizenship rights for all individuals, regardless of race or color. Furthermore, they expressed concern about potential abuses stemming from unchecked state power over jury selection processes, warning it could lead to systemic bias and unequal treatment within criminal justice systems.
