Intervention

Under Rule 24(a) of the Federal Rules of Civil Procedure, intervention allows a person who is not a party to an action, who has interests in subject of an action to be joined, instead of waiting to be forced into action, if he or she timely applies to the court to intervene, assuming his interest is not adequately represented by one of the parties. This is called "intervention of right." Under Rule 24(b), the court at its discretion may join a person to an action. This is called "permissive intervention."

Definition from Nolo’s Plain-English Law Dictionary

The procedure under which a third party may join an ongoing lawsuit, providing the facts and the legal issues apply to the intervenor as much as to one of the existing parties. (See also: intervene.)
