Mr. Mani 's contentions were: (1) that under Hindu Law every coparcener in a Hindu undivided family acquires right in the property of such coparcenery on birth and is entitled to a right of joint possession and enjoyment of its entire property, that section 32KK deprives such a coparcener of his rights of property in that that it takes away the rights of the descendants of the landowner to claim for themselves the permissible area and vest them in the head of the family alone so that there is not only an infringement of the right to hold property under article 19 (1 ) (f ) but also dis crimination in favour of the head of the family infringing thereby article 14; (2) that the effect of section 32 KK is that where an undivided family is possessed of land, instead of each of the descendants getting a ceiling area of 30 standard acres, the head of the family alone gets 30 standard acres and therefore the section is violative of article 31; (3) that the section, being applicable only to Hindu undivided families infringes article 15(1) inasmuch as it discriminates by reason only of religion such families as against other undivided families in Punjab amongst communities other than Hindus and (4) that the section cannot be said to be legislation whose object is agrarian reform and, therefore, is not protected by article 31 A. Section 32 KK, the validity of which is impeached in this appeal, reads as follows : "Notwithstanding anything contained in this Act or in any other law for the time being in force : (a) where, immediately before the commencement of this Act, a landowner and his descendants constitute a Hindu undivided family, the land owned by such family shall, for the purposes of this Act, be deemed to be the land of that landowner and no descendant shall, as member of such family, be entitled to claim that in respect of his share of such land he is a landowner in his own right".
