In the case of Boston Metals Co. v. The Winding Gulf et al., 1954, the U.S Supreme Court was tasked with resolving a dispute over maritime law and its application to a contract for the sale of coal between two parties: Boston Metals Company and The Winding Gulf. The issue at hand was whether or not this contract fell under admiralty jurisdiction due to its connection with maritime service despite being primarily about a land-based commodity (coal). In their decision, the court ruled in favor of Boston Metals Co., stating that while contracts related to goods are typically outside admiralty jurisdiction, exceptions can be made when such contracts are tied directly to maritime commerce - as it was in this case where coal was sold specifically for use on ships. This ruling expanded upon previous interpretations of what constitutes "maritime" transactions by including those which have significant impacts on navigation or commerce at sea.

In the dissenting opinion for Boston Metals Co. v. The Winding Gulf et al., Justice Robert H. Jackson disagreed with the majority's decision to uphold a lower court ruling that allowed an injured seaman to sue his employer under general maritime law, rather than being limited to workers' compensation benefits provided by state law or federal statute. He argued that this interpretation of maritime jurisdiction was overly broad and inconsistent with previous rulings on similar cases, which had generally held that such disputes should be resolved through statutory remedies rather than common-law tort claims. Furthermore, he contended that allowing seamen to pursue additional damages in court undermined the purpose of workers' compensation laws, which were designed to provide quick and certain relief without litigation while also protecting employers from potentially ruinous lawsuits.
