The learned counsel for the respondents submits that the suit is of the year 1986 and the petitioner filed the petition for impleadment of the purchasers from the defendants after much delay but I find that the suit is for specific performance of contract. During the pendency of the suit defendants No. 6, 7, and 8 sold properties and therefore the purchasers are necessary party in the suit for specific performance of contract in which the defendants executed sale deed in favour of the purchasers. The purchasers are entitled to defend their interest as the vendors may not pursue the case with same interest after selling the properties during the pendency of the suit. Thus, I find that the learned Sub Judge has committed jurisdictional error in rejecting the petition of the plaintiff for impleading the purchasers as defendants in the suit. Accordingly, the order dated 18.04.2016 passed by learned Sub Judge-14, Bhojpur, Ara in Title Suit No. 37 of 1986 is set aside and the purchasers from the defendants are impleaded as defendants in the suit. This Civil Misc. petition is, accordingly, allowed.
