Imposition of Ceiling on Land Holdings Act, even if it contravenes the seconds proviso to clause 1 of Article 31 A, a matter on which we do not wish to express any opinion since it is unnecessary to do so, is validated under Article 31 B" and "that Section 5 sub clause (6) of the U P Imposition of Ceiling on Land Holdings Act is valid and its constitu tionality cannot be assailed by reason of the immunity enacted in Article 31 B." In a later case Ambika Prasad vs U.P.
