In Thomas Jackson et al. v. William E. Ashton, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving citizens of different states and property located in another state. The appellants argued that the Circuit Court of Ohio lacked jurisdiction because it involved parties from other states and real estate situated in Pennsylvania; however, the appellee contended that since he was an inhabitant of Ohio at the time when suit was brought against him, his residence conferred upon its courts jurisdiction over this controversy between himself and persons residing out of its limits. After considering both arguments carefully, the Supreme Court held that although there were some exceptions to this rule which would allow for such cases to be heard by federal courts instead of state ones, none applied here so they affirmed judgment below on grounds that Ohio's Circuit Courts had proper authority under their laws to hear this dispute as it related solely to matters within their own borders.

In Thomas Jackson et al. v. William E. Ashton, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving citizens of different states and an issue that arose in another state. The majority opinion held that the lower court did have jurisdiction, but Justice Story dissented from this decision on two grounds: firstly, he argued that under Article III of the Constitution, federal courts should be given exclusive authority to hear cases between citizens of different states; secondly, he contended that even if it were permissible for a state court to exercise such authority in certain circumstances (which he doubted), this particular case did not meet those criteria because there was no evidence suggesting any connection between the parties or their dispute and the forum where they appeared before trial began. In conclusion, Justice Story believed that allowing state courts to adjudicate disputes between citizens of other states would lead to confusion and uncertainty about which laws applied when resolving these matters - something best avoided by leaving such questions exclusively within federal judicial power as provided for by Article III
