The legal case of COUGHRAN et al. v. BIGELOW et al. is about a dispute between Eugene W. Coughran, Nathan H. Cottrell, Henry C. Bigelow, and H.P. Henderson regarding a property transaction that occurred on April 26, 1890. According to the information provided, Coughran and Cottrell filed an amended complaint in the district court of the First judicial district of the territory of Utah on December 15, 1891, against Bigelow and Henderson. The case appears to have reached the Supreme Court of the United States, with the decision being rendered on November 30, 1896. The Supreme Court's decision seems to have addressed the issue of whether a trial court's granting of a nonsuit for lack of sufficient evidence to warrant a verdict for the plaintiff constitutes an infringement of the constitutional right to trial by jury.
