Civil Revision (CRP/75/2024) under Section 115 CPC by the judgment-debtor defendant against dismissal of his Misc Appeal No. 07/2018 confirming rejection of his Order IX Rule 13 application (Misc (J) Case No. 88/2016) for setting aside the ex-parte decree dated 18.04.2016 in Title Suit No. 112/2014 (declaration of title, khas possession and injunction over Dag No. 278, Tiling Gaon, Kamrup). Allowing the revision, the Gauhati High Court (Devashis Baruah, J.) catalogued the Trial Court's errors: (i) proceeding ex-parte on 11.09.2014 although the suit was not fixed for hearing but only for service report after the plaintiff's counsel sought withdrawal, contrary to Order IX Rule 7; (ii) refusing the appearing defendant permission to participate on 07.04.2015; (iii) on 22.06.2015, instead of granting an adjournment under Order XVII Rule 1(1) or proceeding under Order XVII Rule 3 when the plaintiff sought time and his witnesses were absent, fixing the suit for ex-parte argument and judgment; and (iv) delivering judgment on 18.04.2016 more than six months after the date fixed, contrary to Order XX Rule 1. Relying on Sangram Singh v. Election Tribunal, Kotah (AIR 1955 SC 425) and Arjun Singh v. Mohindra Kumar (AIR 1964 SC 993), the Court held that a defendant who has appeared under summons and filed his written statement can be proceeded against ex-parte only when the suit is fixed for hearing, and cannot be stopped from participating once he appears at an adjourned hearing. The defendant was held 'prevented by sufficient cause' — prevented by the Trial Court contrary to law — from appearing; both courts below had failed to exercise their jurisdiction. The orders dated 21.08.2018 and 13.03.2024 were quashed, the Order IX Rule 13 application allowed, the decree dated 18.04.2016 set aside, and the suit restored to proceed from the cross-examination stage before the Civil Judge (Junior Division), Kamrup at Amingaon from 07.04.2025, with no costs.
