In Galloway v. United States (1942), the U.S. Supreme Court ruled on a case involving the Seventh Amendment, which guarantees a trial by jury in civil cases. The plaintiff, Galloway, had sued for damages claiming that he was wrongfully committed to an insane asylum by government officials. After hearing evidence from both sides during the trial, the judge directed a verdict in favor of the defendants without letting it go to jury deliberation because he believed no reasonable juror could find for Galloway based on presented evidence. Galloway appealed this decision arguing that his Seventh Amendment rights were violated as he was denied his right to have his case decided by a jury rather than solely by a judge's interpretation of law and facts. The Supreme Court upheld lower court’s ruling stating that judges do not violate litigants' constitutional rights when they direct verdicts if there is insufficient evidence upon which any reasonable person could base their judgment against other party involved in lawsuit. This landmark decision clarified judicial power over directing verdicts and affirmed judges’ authority to prevent unnecessary or pointless trials where there is no legally sufficient evidentiary basis for rational jurors’ decisions.

In the dissenting opinion for Galloway v. United States, Justice Black argued that the majority's decision undermined a fundamental right of American citizens - the right to a trial by jury. He contended that this case was not about whether there was enough evidence for a reasonable person to find guilt beyond reasonable doubt, but rather if there was any evidence at all which could lead to such conclusion. According to him, it is up to juries and not judges or appellate courts, no matter how clear they believe the facts are against defendant’s favor, to decide on matters of fact in criminal cases. The judge's role should be limited only as an advisor and guide regarding law interpretation while leaving factual determinations solely with jurors who represent community sentiment and standards.
