determination of the said question is essentially qua the plaintiff, who was a party defendant to the suit to which the said decree came to be passed. It is not the case that the decree passed in Suit No. 54 of 1967 affects the rights of the applicants. In the event, the applicants claim that the consent decree in Suit No.54 of 1967 affects the rights of the applicants as well and does not bind them, the applicants would be required to take out a substantive proceedings. The impleadment of the applicants is thus not necessary for a complete and effectual adjudication of the dispute between the plaintiff and the defendants. So far as the apprehension on the part of the applicants that the instant suit may be compromised by the parties thereto and in that event, the rights of the applicants may be jeopardized, it would be suffice to direct that in the event, the instant suit is compromised between the parties, the plaintiff and the defendants, (who may be parties to the said compromise) shall intimate the said fact to the applicants within a period of four weeks of entering into such compromise.
