In the case of Chicago, Rock Island and Pacific Railway Company v. Martin in 1899, the U.S Supreme Court ruled on a dispute involving an employee injury claim against his employer, a railway company. The plaintiff, Martin was injured while working for the defendant railway company due to alleged negligence by another employee. He sued under Iowa state law which allowed employees to sue their employers for injuries caused by fellow workers' negligence if it resulted from some fault or neglect on part of the employer. However, this contradicted federal laws that did not hold employers liable in such cases unless there was direct negligence from them. The Supreme Court held that although states have power over local matters like personal injury claims within their jurisdictional boundaries; when these matters involve interstate commerce companies (like railroads), they are subject to federal regulation and thus fall under its jurisdiction instead of individual state laws. Therefore, despite Iowa's law allowing suits against employers for co-worker negligence causing injuries at work; since this involved an interstate railroad company - it fell under federal regulations which didn't allow such lawsuits without proving direct employer’s negligence – hence ruling in favor of Chicago Rock Island & Pacific Railway Co., thereby limiting liability exposure for similar businesses operating across multiple states.

In the dissenting opinion for the case Chicago, Rock Island and Pacific Railway Company v. Martin, Justice Harlan disagreed with the majority's ruling that a state could not regulate interstate commerce rates without violating federal law. He argued that states should have authority to protect their citizens from unreasonable charges by corporations operating within their borders until Congress decides to act on such matters. In his view, if a state regulation does not conflict directly with federal legislation or impede free trade among states, it should be allowed to stand. He also emphasized that railroads were public highways established under governmental authority and thus subject to regulatory control in order to prevent abuses of power against individuals or communities they serve.
