Illegal substitution is a rarely called bench minor penalty which is called when a substitution or addition is attempted during a stoppage of play after the linesmen have signaled no more substitutions (once the face-off is set) or if a team pulls its goaltender and then attempts to have the goaltender re-enter play at any time other than during a stoppage of play. Too many men on the ice and/or starting the wrong lineup can also simply be called a substitution infraction.
