In the case of Otis v. Walter, the Supreme Court was asked to decide whether a state court had jurisdiction over a dispute between two citizens from different states. The plaintiff, Otis, argued that because he and his opponent were both citizens of different states, only federal courts could hear their case. However, the defendant argued that since they were both in-state at the time of filing suit and all other parties involved resided in-state as well, then it should be heard by a state court instead. Ultimately, after considering arguments from both sides on matters such as diversity jurisdiction and comity among states under Article IV Section 2 Clause 1 of the Constitution (the “Full Faith & Credit” clause), Chief Justice Marshall ruled in favor of Walter stating that while federal courts have exclusive authority when there is complete diversity among parties involved (i.e., no party resides within same state) this did not apply here due to lack thereof; thus allowing for concurrent jurisdiction with state courts over disputes between citizens from different states so long as all other relevant factors are present - including residence within same state at time suit is filed - which was found to be true here given all parties lived in Pennsylvania where lawsuit originated..

In this case, the Supreme Court was asked to decide whether a state court had jurisdiction over an action brought by a citizen of another state. The plaintiff argued that he should be allowed to bring suit in his home state because it would be more convenient for him and less expensive than bringing suit in the defendant's home state. However, the majority opinion held that states have exclusive jurisdiction over their own citizens and therefore could not allow suits from other states without violating their sovereignty. Justice Story dissented from this ruling on several grounds. He argued that allowing citizens of one state to sue in another did not violate any principle of federalism or interfere with any right belonging exclusively to either party; instead, it provided greater access to justice for all parties involved regardless of where they lived. Furthermore, he noted that such suits were common practice among many nations around the world and thus should be permitted under American law as well.
