“ 11. At the outset, it is required to be noted that the defendants in the suit filed application under Order 1 Rule 10 CPC and prayed to implead the subsequent purchasers as party defendants. The suit is for declaration, permanent injunction and recovery of possession. As per the settled position of law, the plaintiffs are the dominus litis. Unless the court suo motu directs to join any other person not party to the suit for effective decree and/or for proper adjudication as per Order 1 Rule 10 CPC, nobody can be permitted to be impleaded as defendants against the wish of the plaintiffs. Not impleading any other person as defendants against the wish of the plaintiffs shall be at the risk of the plaintiffs. Therefore, subsequent purchasers could not have been impleaded as party defendants in the application submitted by the original defendants, that too against the wish of the plaintiffs .”
