Dismissal of an action or proceeding for non-joinder of a necessary party is a last resort. When a necessary party has not been made a party and is subject to the jurisdiction of the court, the proper remedy is not dismissal of the complaint, but, rather, for the court to order that the necessary party be summoned.
