What happens if a crewmember wasn’t injured, but actually caused an injury to a fellow crewmember or passenger? This usually occurs in the context of medical negligence or battery. In some jurisdictions, if a cruise ship staff member injured another person, the owners of the cruise ship may be held liable for their employees’ actions. In other jurisdictions, the cruise ship owners will not be held liable for the actions of crewmembers unless the injured party can show that the owner knew that the crewmember was violent or dangerous and did nothing to prevent the injury that occurred, or that the crewmember was negligently hired by the owner. Claims against the employer may differ depending on the facts of the case, applicable law and jurisdiction.
