The U.S. Supreme Court case Fore River Shipbuilding Company v. Hagg in 1910 revolved around a dispute over the interpretation of maritime law and its application to worker's compensation claims. The plaintiff, Mr. Hagg, was an employee at Fore River Shipbuilding Company who suffered injuries while working on a ship that was under construction but not yet launched or completed. He sought damages for his injuries from his employer under federal maritime law rather than state workers' compensation laws which would have limited his recovery amount. The central issue before the court was whether the incomplete status of the ship meant it did not qualify as a "vessel" within the meaning of federal maritime law, thus placing Mr.Hagg's claim outside its jurisdiction.The Supreme Court ruled in favor of Fore River Shipbuilding Company, holding that an unfinished ship is not considered a vessel according to federal maritime law until it has been launched or put into service.This ruling effectively excluded such injury cases from being covered by more generous provisions available under this legislation and instead subjected them to state workers' compensation laws.

In the dissenting opinion for the case of Fore River Shipbuilding Company v. Hagg, it was argued that the majority's decision to hold a shipbuilder liable for injuries sustained by an employee due to defective equipment provided by another company was unjust. The dissenter believed that this ruling expanded liability beyond reasonable limits and could have far-reaching implications on business relationships and contracts. They contended that if a party is not directly responsible for creating or maintaining unsafe conditions, they should not be held accountable when accidents occur as a result of those conditions. This perspective emphasized individual responsibility over collective accountability in workplace safety matters, suggesting that each entity involved in complex industrial processes must bear its own share of risk rather than shifting blame onto others who may not have direct control over every aspect of operations.
