Fussell v. Gregg & Others was a United States Supreme Court case that dealt with the issue of whether a state court had the authority to issue a writ of mandamus to a federal court. The case involved a dispute between the plaintiff, Fussell, and the defendants, Gregg & Others, over a contract for the sale of a steamboat. Fussell had sued the defendants in a federal court, but the defendants argued that the contract was void and that the federal court had no jurisdiction over the matter. The defendants then asked the state court to issue a writ of mandamus to the federal court, ordering it to dismiss the case. The Supreme Court held that the state court did not have the authority to issue a writ of mandamus to a federal court. The Court reasoned that the state court was not a superior court to the federal court, and that the state court did not have the power to control the proceedings of the federal court. The Court also noted that the state court had no authority to review the decision of the federal court. The Court concluded that the state court had no authority to issue a writ of mandamus to the federal court, and that the writ was therefore void.

In Fussell v. Gregg & Others, the United States Supreme Court was tasked with determining whether a state court had jurisdiction to hear an appeal from a federal district court decision. The majority opinion held that the state court did not have jurisdiction because it lacked authority over matters of federal law and procedure. Justice Field dissented, arguing that Congress had given states broad powers to review decisions made by lower courts in order to ensure justice is served for all parties involved. He argued that since there were no explicit limitations on this power granted by Congress, then the state should be allowed to exercise its right of review as long as it does not interfere with any other laws or regulations set forth by Congress or the Constitution itself. Furthermore, he noted that allowing such appeals would help protect citizens’ rights and provide them with more avenues for seeking relief when they feel wronged by a lower court’s decision.
