The U.S. Supreme Court case Northeast Marine Terminal Co., Inc., et al. v. Caputo et al., 1976, revolved around the interpretation of the Longshoremen's and Harbor Workers' Compensation Act (LHWCA). The plaintiffs, two longshoremen who were injured while working on a pier in New York City, sought compensation under LHWCA for their injuries. Their employers argued that they weren't eligible because their work was not directly related to maritime activity as it involved unloading cargo from trucks onto piers rather than ships into piers or vice versa. However, the Supreme Court ruled in favor of the workers by interpreting "navigable waters" broadly to include areas adjoining water where loading/unloading takes place such as docks and terminals - thus extending coverage under LHWCA beyond traditional stevedoring activities performed aboard ship to encompass land-based operations integral to shipping process. This decision expanded protections for waterfront workers by recognizing that modern realities of maritime commerce often involve significant shoreside activities which are just as crucial and hazardous as those conducted onboard vessels.

In the dissenting opinion for Northeast Marine Terminal Co., Inc. v. Caputo, Justice Rehnquist disagreed with the majority's broad interpretation of "employee" and "navigable waters" under the Longshoremen's and Harbor Workers' Compensation Act (LHWCA). He argued that such an expansive reading was not supported by legislative history or precedent, which traditionally limited coverage to workers engaged in maritime employment on navigable waters. The majority’s decision extended LHWCA benefits to longshoremen who were injured while working on land, a move Rehnquist believed encroached upon state jurisdiction over workers’ compensation claims. Furthermore, he expressed concern about potential economic implications of this ruling as it could increase costs for employers without clear evidence that Congress intended such consequences when they enacted LHWCA.
