In James Boyce's Executors v. Felix Grundy, the Supreme Court of the United States was asked to decide whether a state court had jurisdiction over a case involving citizens from different states. The executors of James Boyce brought suit against Felix Grundy in Tennessee for an unpaid debt that originated in Kentucky. The lower court dismissed the case on grounds that it lacked jurisdiction because both parties were not citizens of Tennessee and thus could not be sued there according to Article III Section 2 Clause 1 of the Constitution which grants federal courts exclusive jurisdiction over cases between two or more states. On appeal, however, the Supreme Court reversed this decision and held that state courts have concurrent jurisdiction with federal courts when both parties are citizens from different states as long as they do not involve questions regarding public rights or interests under national law. This ruling established precedent for future cases where one party is suing another citizen from another state in their own home state’s court system without having to go through a lengthy process at a federal level first.

In James Boyce's Executors v. Felix Grundy, 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 reversed the decision of the lower court. However, Justice McLean dissented from this ruling on two grounds: firstly, he argued that as long as there is no conflict between federal and state laws regarding interstate disputes then they should be decided by state courts; secondly, he argued that if Congress has not legislated in regards to such matters then it is up to each individual State to determine how these cases are handled within their own borders. He concluded his dissent by stating that “the Constitution does not confer upon this Court any power or authority whatever over questions arising under the judicial system of any particular State” and thus found for Grundy in reversing the decision of the lower court.
