In the case of Jamison et al., Executors, v. Encarnacion in 1929, the U.S Supreme Court ruled on a matter involving inheritance laws and jurisdictional issues between Puerto Rico and New York. The dispute arose when Maria Encarnacion claimed she was entitled to an inheritance from her deceased husband's estate which was being administered in New York but had been denied by the executors due to their belief that under Puerto Rican law she wasn't eligible as they were divorced at his time of death. However, Ms. Encarnacion argued that since her ex-husband died domiciled in New York, its more lenient laws regarding divorcees' rights to inherit should apply instead. The Supreme Court sided with Ms.Encarnacion stating that although generally local law determines succession rights for real property located within its territory (lex rei sitae), it is not absolute especially when dealing with personal properties where domicile or residence can be considered (lex domicilii). Therefore, since Mr.Jamison died while resident in NY state whose laws did not bar divorced spouses from inheriting unless explicitly stated so by decedent prior to death - unlike PR’s stricter rules - then these should prevail over those of PR thus entitling Ms.Encarnacion access to said assets.

The dissenting opinion in the case of Jamison et al., Executors, v. Encarnacion argued that the majority's decision to uphold a lower court ruling was incorrect and inconsistent with established legal principles. The dissenting justices believed that the plaintiff should not have been allowed to sue for damages because they had failed to exhaust all available local remedies before seeking relief from U.S courts. They also disagreed with the majority's interpretation of international law, arguing that it did not provide a basis for allowing such lawsuits in this context. Furthermore, they contended that by permitting these types of claims without requiring plaintiffs to first pursue local remedies, U.S courts risked interfering with foreign governments' ability to manage their own affairs and potentially damaging diplomatic relations between countries.
