In James Boyce's Executors, Appellants vs. Felix Grundy, Appellee (1830), the Supreme Court of the United States was asked to determine whether a state court had jurisdiction over an estate dispute between citizens of different states. The case arose when James Boyce died in Tennessee and left his entire estate to his executor, who resided in Kentucky. When Felix Grundy sued for part of the estate on behalf of himself and other heirs living in Tennessee, he argued that since all parties were citizens from different states, only federal courts could hear such cases under Article III Section 2 Clause 1 of the Constitution. However, after reviewing precedent set by previous decisions as well as relevant statutes passed by Congress regarding diversity jurisdiction matters at that time period; Chief Justice Marshall concluded that state courts did have authority over such disputes between citizens from different states if they involved less than $500 dollars or more depending on local laws governing such issues within each individual state’s borders. This decision established important legal principles concerning diversity jurisdiction which are still applicable today when determining where certain types civil actions can be heard according to current federal law

In James Boyce's Executors, Appellants vs. Felix Grundy, Appellee (1830), the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving citizens of different states. The majority opinion held that it did not have such jurisdiction and thus dismissed the suit. However, in his dissenting opinion Justice Thompson argued that the Constitution does not explicitly prohibit suits between citizens of different states from being heard by state courts and therefore they should be allowed to hear them if Congress has not prohibited it through legislation or otherwise provided for its regulation. He further argued that since there is no federal law on this matter then each individual state should be able to determine how best to handle these cases within their own borders as long as they do so consistently with principles of justice and equity. In conclusion, he believed that allowing state courts to exercise jurisdiction over these types of cases would promote harmony among all parties involved while also protecting individuals’ rights under both federal and state laws.
