The plaintiff student brought an action against the defendant student, school board, and teachers, for injuries sustained in a physical altercation that took place on school premises. The school board and teachers were alleged to have been negligent in failing to provide adequate supervision to prevent the altercation from occurring. Justice Arrell held that there was no liability on the school, teachers, or school board. The applicable standard of care was that of a careful and prudent parent. The school had a supervision policy, surveillance cameras, and numerous teachers circulating in the hallways in between classes. There was no evidence to suggest that school supervision fell below the standard of a reasonable and prudent parent of a teenager. The action as against the teachers and school board was dismissed.
