Camp Jaycee (defendant) was a charitable organization that operated a summer camp for individuals with mental disabilities. Although Camp Jaycee was organized under New Jersey law and maintained an office in New Jersey, the camp was located in Pennsylvania. P.V., a New Jersey resident, attended the camp in Pennsylvania for three summers and claimed that she had been sexually assaulted by another camper. P.V.’s parents (plaintiffs) filed suit in New Jersey state court asserting claims against Camp Jaycee for negligent supervision. The trial court granted Camp Jaycee’s motion for summary judgment, applying New Jersey’s charitable-immunity statute. The appellate division reversed, holding that the matter was controlled by Pennsylvania law, which did not recognize charitable immunity. The supreme court granted Camp Jaycee’s petition for certification.
