The U.S. Supreme Court case Minneapolis & St. Louis Railroad Company v. Bombolis, Administrator of Nanos, 1915 revolved around a dispute over the jurisdiction of state courts in cases involving federal issues under the Federal Employers' Liability Act (FELA). The plaintiff's husband was killed while working for the railroad company and she sued them for negligence under FELA in a Minnesota state court. The defendant argued that only federal courts had jurisdiction to hear such cases but lost at both trial and appellate levels in Minnesota before appealing to the Supreme Court. The Supreme Court upheld the lower court decisions, ruling that state courts could indeed exercise concurrent jurisdiction with federal courts on matters arising from FELA as long as they applied federal law when deciding these cases. This decision clarified an important aspect of American jurisprudence regarding how different legal jurisdictions interacted with each other especially concerning labor laws.

In the dissenting opinion for Minneapolis & St. Louis Railroad Company v. Bombolis, Justice Hughes argued that the Seventh Amendment should apply to state courts when they are enforcing federal rights, contrary to what was decided by the majority of justices in this case. He believed that if a lawsuit is based on a federal law or right and it's being tried in a state court, then all aspects of federal law - including constitutional amendments - should be applied as well. This would ensure uniformity across different jurisdictions and uphold citizens' rights under federal laws regardless of where their cases are heard. In his view, allowing states to ignore parts of the Constitution while enforcing other parts could lead to inconsistencies and unfairness in how justice is administered throughout the country.
