In the case of Missouri, Kansas and Texas Railway Company v. Elliott in 1901, the U.S Supreme Court ruled on a dispute involving railway company negligence. The plaintiff, Mr. Elliott was injured while working for the railway company when he fell from a train due to an allegedly defective handrail which his employer failed to repair or replace despite knowledge of its condition. He sued for damages under federal law that held employers liable for injuries caused by their negligence. The lower court found in favor of Mr.Elliott but upon appeal, the Supreme Court reversed this decision stating that there was insufficient evidence presented at trial proving that the railroad had prior knowledge about defectiveness of handrail and thus could not be held responsible for negligence as per federal law requirements. This ruling highlighted how crucial it is to provide substantial proof demonstrating an employer's awareness and disregard towards hazardous conditions leading to employee injury within workplace safety litigation cases.

In the dissenting opinion for Missouri, Kansas and Texas Railway Company v. Elliott (1901), Justice Harlan disagreed with the majority's decision that a railway company could not be held liable for injuries sustained by an employee due to negligence of another employee at roughly the same level of employment. He argued that this ruling contradicted previous decisions where companies were found responsible for damages caused by their employees' carelessness or incompetence while performing their duties. Furthermore, he contended that it was unjust to exempt corporations from liability when they profit from the labor of those who are injured in service to them. In his view, employers should bear responsibility for ensuring safe working conditions and practices among all workers regardless of rank or position within the company hierarchy.
