This is a Second Regular Appeal (RSA No. 22/2012) before the Gauhati High Court arising from a title and possession dispute over agricultural land in Barpeta, Assam. The original plaintiff, Smt. Tarubala Saha (whose legal heirs are the respondents), claimed she had purchased approximately 4 bigha 2 katha 10 lecha of land via registered Sale Deed No. 2912/75 dated 18.02.1975 from Nagar Ali, who acted for himself and as guardian of his minor siblings, and that the defendants (appellants) illegally dispossessed her in 2009. The defendants/appellants contended that the sale deed was void ab initio as Nagar Ali had no valid guardianship certificate, that the suit was bad for non-joinder of necessary parties, and filed a counter-claim seeking declaration that the sale deed was void. The Trial Court (Munsiff No. 1, Barpeta) partly decreed the suit in favour of the plaintiff, declaring her title and granting possession, while dismissing the defendants' counter-claim as barred by limitation; the First Appellate Court (Civil Judge, Barpeta) affirmed this decree. The substantial question of law admitted in this second appeal is whether the lower appellate court erred in holding that the plaintiff had right, title and interest over the suit land despite the alleged voidness of the sale deed.
