In Pullman's Palace Car Company v. Missouri Pacific Railway Company & Another, the Supreme Court of the United States was asked to decide whether a state court had the authority to enjoin a federal court from hearing a case. The case involved a dispute between Pullman's Palace Car Company and the Missouri Pacific Railway Company over a contract for the transportation of Pullman's cars. The state court had issued an injunction preventing the federal court from hearing the case, and Pullman's appealed the decision to the Supreme Court. The Supreme Court held that the state court did not have the authority to enjoin the federal court from hearing the case. The Court reasoned that the state court's injunction was an attempt to interfere with the federal court's jurisdiction, and that such interference was prohibited by the Constitution. The Court also noted that the state court's injunction was an attempt to control the proceedings of the federal court, which was also prohibited by the Constitution. The Court concluded that the state court's injunction was invalid and that the federal court had the authority to hear the case. The Court also noted that the state court's injunction was an attempt to interfere with the federal court's jurisdiction, and that such interference was prohibited by the Constitution.

In Pullman's Palace Car Company v. Missouri Pacific Railway Company & Another, the Supreme Court was tasked with deciding whether a state court had jurisdiction to hear an action brought by one railroad company against another for damages resulting from alleged negligence in failing to provide adequate protection of goods shipped between two states. The majority opinion held that the state court did not have jurisdiction over such matters and that it should be heard in federal court instead. However, Justice Field dissented on this point, arguing that since the parties were both domestic corporations operating within a single state and their dispute arose out of activities conducted entirely within said state, then it would be appropriate for the matter to remain under its jurisdiction. He further argued that allowing cases like these to proceed in federal courts could lead to unnecessary delays as well as increased costs due to additional fees associated with filing suit there rather than at a local level. Ultimately he concluded by stating his belief that Congress never intended for interstate commerce disputes involving purely intrastate activity or transactions between domestic companies located solely within one particular State’s borders should be adjudicated exclusively by Federal Courts
