Japanese Archery

A boy of 15 was expelled from school after mucking around and shooting his classmate in the face with an arrow during archery. The victim sustained major wounds. The school said that this was clearly an "anti social act."

However, the boy who was expelled has decided to sue the school and asked the school to take him back on board saying that "an accident cant be called anti social" and that "the victim has not requested that I be expelled."

You are the headmaster of the school - what would you do?
