Section 72 of the Constitution is the exclusive provision governing compulsory acquisition of agricultural land for public purposes including settlement, and it operates independently of section 71 which applies to other property. Compulsory acquisition of agricultural land under section 72(2) is effected by publication of a notice in the Gazette identifying the land and stating the purpose, whereupon title vests in the State with full title from the date of publication. The procedural requirements of section 71(3) - including prior notice to affected persons, payment of compensation for the property, and judicial confirmation if contested - do not apply to agricultural land acquisitions under section 72. The proviso to section 5(1) of the Land Acquisition Act confirms that for 'specially Gazetted Land' (agricultural land), publication in the Gazette and local newspaper constitutes sufficient notice. The Administrative Justice Act does not apply to compulsory acquisition of agricultural land as section 72 of the Constitution specifically governs such acquisitions. Compensation under section 72 is payable only for improvements made on the land prior to acquisition, not for the land itself. Such acquisitions can be challenged on grounds of illegality, irrationality, or procedural impropriety, but not on grounds of discrimination under section 56 or for compensation for the land (section 72(3)).
