In the case of Louisville Trust Company v. Comingor in 1901, the U.S. Supreme Court ruled on a dispute involving land ownership and inheritance laws. The plaintiff, Louisville Trust Company, was acting as an executor for a will that left property to several beneficiaries who were all British subjects residing outside of the United States. However, under Kentucky law at that time (where the property was located), non-U.S residents could not inherit real estate directly and it had to be sold with proceeds going to them instead. The defendant, Comingor claimed he had purchased part of this land from one such beneficiary before they died but after their interest in it arose through inheritance - thus arguing his claim superseded any rights by other beneficiaries or creditors involved in executing said will. The court held that despite state law restrictions on foreign ownerships of lands; once vested interests are created via testamentary dispositions (i.e., through a will), those interests cannot be divested simply because subsequent events render these individuals incapable of holding such properties according to local laws. Therefore, even though some beneficiaries couldn't legally own Kentucky land due to being foreign citizens; since their rights originated from valid provisions within a will - these remained enforceable regardless which meant Comingor's purchase wasn't legitimate as he thought.

In the dissenting opinion for Louisville Trust Company v. Comingor, it was argued that the majority's decision to uphold a tax on shares of national banks held by non-residents contradicted previous rulings and violated federal law. The dissenting justices believed that this interpretation of Kentucky state law unfairly targeted out-of-state shareholders and placed an undue burden on them compared to in-state shareholders. They contended that such taxation should be uniform across all shareholders regardless of their residency status, as mandated by federal statute regarding taxation of national bank shares. Furthermore, they expressed concern over potential negative impacts on interstate commerce due to discriminatory treatment against non-resident investors.
