In the case of Johnson v. United States in 1912, the Supreme Court ruled on a matter involving maritime law and personal injury. The plaintiff, Mr. Johnson, was a seaman aboard one of the defendant's vessels when he suffered an injury due to negligence by his employer (the ship owner). He sought compensation for his injuries under general maritime law as well as additional damages under state laws which provided further protections for workers injured on the job. However, it was determined that these state laws did not apply because they were inconsistent with federal legislation governing such matters - specifically, they conflicted with limitations set forth in federal statutes regarding liability for injuries at sea. Therefore, while Mr. Johnson could seek compensation under general maritime law for his injuries sustained through negligence by his employer; he could not claim additional benefits or damages based on state labor protection laws.

In the dissenting opinion for Johnson v. United States, Justice Holmes argued that the defendant's constitutional rights were violated when he was denied a trial by jury. He believed that even though Johnson had pleaded guilty to his charges, he still deserved a chance to present his case before a jury of his peers. According to Holmes, this right is fundamental and should not be waived simply because someone admits guilt. Furthermore, he contended that it was unfair for the court to impose such severe penalties without giving Johnson an opportunity to defend himself or challenge the evidence against him. In essence, Holmes felt strongly that every individual deserves their day in court regardless of how clear-cut their guilt may seem.
