(1) An order made in a proceeding for or against a representative party is binding on each person represented by the representative party.
(2) However, the order can be enforced against a person who is not a party only if the Court gives leave.
(3) An application for leave under subrule (2) must be served personally on the person against whom it is sought to enforce the order.
(4) A person who is served with a notice under subrule (3) may dispute liability to have the order to which the notice relates enforced against the person on the ground that facts and matters particular to the person entitle the person to be exempt from liability.
