In P. C. Pfeiffer Co., Inc., et al. v. Ford et al., the U.S Supreme Court was tasked with determining whether certain workers were considered "maritime employees" under the Longshoremen's and Harbor Workers' Compensation Act (LHWCA). The case involved two sets of respondents: one group who worked on a floating platform loading and unloading cargo from ships, and another group who moved cargo around once it had been unloaded onto land at a marine terminal facility. The court held that both groups of workers were indeed maritime employees as defined by LHWCA because their duties constituted an integral part of the process of loading or unloading a vessel, which is essential to maritime commerce. Therefore, they are entitled to compensation for injuries sustained during work under this act. This decision clarified the definition of "maritime employee", expanding its scope beyond those directly engaged in navigation or traditional seafaring roles to include any worker involved in activities crucial to maritime commerce.

The dissenting opinion in the P. C. Pfeiffer Co., Inc., et al. v. Ford et al case argued that the majority's interpretation of "any harbor worker" was too broad and not consistent with Congress' intent when it enacted the Longshoremen's and Harbor Workers' Compensation Act (LHWCA). The dissent believed that a more narrow definition, which would only include workers who are directly involved in loading or unloading ships, should be applied instead of including all employees working within navigable waters regardless of their duties or functions. They contended that this broader interpretation could lead to unintended consequences such as extending coverage to office workers simply because they work near a harbor, something they believe Congress did not intend when drafting LHWCA.
