The reasoning which has prevailed with us for sustaining the validity of the provisions of the Maharash tra Agricultural Lands (Ceiling of Holdings) Act, 1961 must apply equally in the present cases arising under the Punjab Land Reforms Act, 1972 and we must hold that the impugned provisions of the Punjab Land Reforms Act, 1972 are not in conflict with the second proviso to clause (1) of Article 31A and in any event, they are protected from inval idation under Article 31 B. We may point out that the same view has been taken by this Court in regard to the constitutional validity of the relevant provisions of the Gujarat Agricultural Land Ceil ing Act (27 of 1961) in Hansmukhlal vs State of Gujarat.(1) The relevant provisions of the Punjab Land Reforms Act, 1972 are almost the same as those of the Gujarat Agricultural Land Ceiling Act (27 of 1961) which were upheld as constitu tionally valid in Hansmukhlal 's case (supra).
