In the case of William King v. John Mitchell et al., the Supreme Court was asked to decide whether a state court had jurisdiction over a dispute between citizens of different states. The appellant, William King, argued that since he and his opponents were all citizens of different states, only federal courts could hear their case. However, the appellees contended that because they were suing in a state court for an injury committed within its borders, it had jurisdiction over them regardless of their citizenship status. After considering both sides’ arguments carefully, the Supreme Court ruled in favor of Mitchell et al., finding that while federal courts have exclusive jurisdiction when parties are from different states and there is diversity among them (as was true here), this does not apply if one or more parties are suing for an injury sustained within the boundaries of a particular state; thus allowing such cases to be heard by local courts instead. This decision established important precedent regarding which types of disputes can be adjudicated at either federal or state level depending on where they occurred and who is involved in them.

In the case of William King v. John Mitchell et al., the Supreme Court was asked to decide whether a state court had jurisdiction over an action brought by citizens of one state against citizens of another. The majority opinion held that it did not, as such suits were prohibited by Article III, Section 2, Clause 1 of the Constitution. However, Justice Story dissented from this decision and argued that Congress has authority to grant jurisdiction in cases between citizens of different states under its power to regulate commerce among them. He further noted that there is no express prohibition on such suits in either Article III or any other part of the Constitution; therefore he concluded that Congress should be allowed to exercise its discretion in determining when they can be heard before federal courts.
