Felix Frankfurter,
Romero v. International Terminal Operating Company…
“ We perceive no barrier to the exercise of 'pendent jurisdiction' in the very limited circumstances before us. Here we merely decide that a district judge has jurisdiction to determine whether a cause of action has been stated if that jurisdiction has been invoked by a complaint at law rather than by a libel in admiralty, as long as the complaint also properly alleges a claim under the Jones Act. We are not called upon to decide whether the District Court may submit to the jury the 'pendent' claims under the general maritime law in the event that a cause of action be found to exist. ”
