Knotts et al. v. Stearns et al. was a United States Supreme Court case that addressed 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 two parties over a contract for the sale of land in the state of Mississippi. The plaintiffs, Knotts et al., sought to compel the defendants, Stearns et al., to perform their obligations under the contract. The defendants argued that the state court lacked the authority to issue a writ of mandamus to a federal court. 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 writ of mandamus was a remedy that was only available to federal courts, and that the state court lacked the authority to issue such a writ. The Court further held that the state court could not compel the defendants to perform their obligations under the contract, as this was a matter that was within the exclusive jurisdiction of the federal court. In conclusion, the Supreme Court held that the state court lacked the authority to issue a writ of mandamus to a federal court, and that the state court could not compel the defendants to perform their obligations under the contract. The Court's decision established that the writ of mandamus was a remedy that was only available to federal courts.

Justice Field delivered the dissenting opinion in Knotts et al. v. Stearns et al., arguing that the majority's decision was contrary to established precedent and would lead to an unjust result for the plaintiff, Mr. Knotts. He argued that under prior decisions of this Court, a party who has been wrongfully dispossessed of land is entitled to recover damages from those responsible for his loss even if they acted without malice or bad faith; however, here the majority held that no such recovery could be had because there was no evidence of malicious intent on behalf of defendants Stearns and others when they entered into possession of Mr. Knotts' property due to a mistake as to title ownership made by their predecessors-in-interest years earlier. Justice Field believed this holding ran counter not only with prior decisions but also with basic principles of justice which dictate that one should not benefit from their own wrongdoing or negligence at another's expense - something he felt applied here since it was undisputedly through defendants' predecessors’ error in judgment regarding title ownership many years ago which led them into wrongful possession in the first place and thus caused injury to Mr. Knotts now seeking redress before this court today..
