Second Appeals (S.A. Nos.215 & 219 of 1987) under Section 100 CPC — Orissa Schedule Areas of Transfer of Immovable Property (by Schedule Tribes) Regulation, 1956 ('Regulation 2 of 1956') — bar on civil court jurisdiction; incapacity of non-tribals to acquire tribal land by adverse possession. Plaintiffs (general caste) claimed title to plot Nos.697 & 698 on the basis of alleged purchase by their father Haradhan Mohanta from tribal predecessors and by adverse possession, and sued to declare the eviction order dated 28.11.1979 passed by the S.D.O., Panchpir in R.M.C. No.87/1976 (restoring the plots to scheduled tribe defendant Nos.3 to 9) illegal, void and without jurisdiction. Trial Court decreed the suit in part (plot No.697 only); the First Appellate Court, by analogous Judgments dated 27.06.1987/13.07.1987 in T.A. Nos.5 & 6 of 1986, declared the plaintiffs' title over both plots. On the substantial questions of law, HELD: (i) where a statutory tribunal is created under Regulation 2 of 1956, the jurisdiction of the Civil Court is expressly barred and a suit will not lie in the Civil Court to challenge the tribunal's decision (Smt. Champabati Devi v. Duryodhan Swain, 2006 (I) OLR 588); (ii) a non-tribal can neither prescribe nor acquire title by adverse possession over property belonging to a tribal, this being specifically prohibited by the special law (Amrendra Pratap Singh v. Tej Bahadur Prajapati, 2004 (II) OLR (SC) 117); (iii) a civil suit challenging eviction and restoration-of-possession orders passed under Regulation 2 of 1956 is barred and not maintainable (Nityananda Nayak v. Biswanath Kalo, 2021 (II) CLR 187). Applying these ratios, the orders in the Regulation 2 of 1956 proceedings were held neither illegal nor arbitrary; the plaintiffs stood precluded from pleading adverse-possession title against scheduled tribes; the suit was held not maintainable and the plaintiffs not entitled to any relief. Both second appeals were allowed; the Judgments and Decrees of the Trial Court (T.S. No.15 of 1982-I) and of the First Appellate Court (T.A. Nos.5 & 6 of 1986) were set aside; the suit was dismissed on contest against defendant Nos.3 to 6 and ex parte against defendant Nos.1,2 & 7 to 9, without cost.
