In the 1918 case of Chicago, Rock Island & Pacific Railway Company v. Maucher, the United States Supreme Court ruled in favor of the railway company. The dispute arose when Maucher was injured while working for the railroad and sought compensation under a federal law known as Employers' Liability Act. However, his injury occurred within a state that had its own workers' compensation laws which conflicted with this federal statute. The court held that since both parties were located in states where these local laws existed at the time of contract and injury, they should be governed by those respective state laws rather than federal legislation. This decision reinforced principles of federalism by acknowledging jurisdictional boundaries between state and national authority over labor relations.

The dissenting opinion in the case of Chicago, Rock Island & Pacific Railway Company v. Maucher argued that the majority's decision to hold the railway company liable for damages was incorrect. The dissenters believed that there was insufficient evidence to prove negligence on part of the railway company and therefore it should not be held responsible for injuries sustained by Mr. Maucher while he was working as a switchman at one of their yards. They contended that accidents can occur even when all safety precautions are taken and thus, liability cannot always be assigned based solely on an unfortunate outcome. Furthermore, they pointed out inconsistencies in testimonies regarding how exactly the accident occurred which cast doubt over whether or not any negligent behavior actually took place.
