After the death of B, the holder of an istimrari estate, on September 28, 1947, leaving no male issue, the Court of Ward~ took over the estate and issued a notice under the provisions of !ht> Ajmer Land and Revenue Regulation, 1877, inviting claims to the estate. While the enquiry was pending, an application was filed to the effect that the appellant was adopted on February 24, 1948. by the widow of ll and that steps should be taken for the confirmation of the adoption u.nder the third pro,·iso to s. 23 of the Regulation. On September 10, 1951, the adoption was confirmed by the President of India. Thereupon the first respondent instituted a suit for a declaration, inter alia, that the appellant was not adopted as a fact and, in the alternative, the adoption was invalid and illegal. The appellant in his defence pleaded that after the confirmation of the adoption by the Central Government, which must be deemed to have considered and decided the factum and legality of the adoption, such questions could not be challe~ged in a civil court in view of s. n9, read with s. 23, of the Regulation and that, therefore, the suit was not maintainable.
