Rajasthan Land Acquisition Act, 1953–Secs. 4, 5, 6 & 17–Acquisition of land–Notification and declaration–Provisions of Sec. 4(5) have not adhered in the acquisition proceedings–No genuine urgency to invoke the extra-ordinary powers because construction of Townhall per se cannot be presumed to be the larger public interest at the cost of depriving poor agriculturists from their livelihoods–Construction of Townhall during the pendency of this litigation is also a mitigating circumstance–Impugned notification and declaration quashed and set aside.
