In the case of United States v. Pittsburgh & West Virginia Railway Company et al., 1925, the Supreme Court examined whether a railroad company could be held liable for damages caused by a fire that started from sparks emitted by one of its locomotives. The court ruled in favor of the railway company, stating that it was not responsible for unforeseeable consequences resulting from lawful activities conducted with due care and skill. This ruling established an important precedent regarding liability law: even if damage is directly traced to an action or event, there must also be proof that such harm was foreseeable and preventable through reasonable care on part of the defendant.

In the dissenting opinion for United States v. Pittsburgh & West Virginia Railway Company et al., it was argued that the Interstate Commerce Commission (ICC) did not have jurisdiction over a lease agreement between two railway companies, as this fell outside of its regulatory powers. The dissenting justices contended that Congress had only given ICC authority to regulate rates and practices affecting interstate commerce, but not contracts or agreements related to property rights such as leases. They believed that allowing ICC oversight in these matters would constitute an unwarranted expansion of federal power into areas traditionally governed by state law and private contract rights. Furthermore, they expressed concern about potential negative impacts on business transactions if parties could no longer rely on their contractual arrangements due to possible interference from federal regulators.
