Held that a mariner may not recover punitive damages on a claim that he was injured as a result of the unseaworthy condition of the vessel. After a hatch blew open and injured his hand, the deckhand filed suit under federal maritime law and sought punitive damages, among other things. However, the U.S. Supreme Court concluded that punitive damages are unavailable in unseaworthiness actions. Justice Alito delivered the opinion of the 6-3 Court.
