market value. He submitted that in para-3 of the impugned order, learned trial Judge observed that the market value of the acquired land is to be determined on the basis of comparable sale instances. Similarly situated lands are required to be examined with reference to the crops taken therein, water facility, proximity to the road and geographical situation of the land are the important facts to be taken into consideration. He submitted that insofar as the acquisition of other lands is concerned, S.L.A.O. has awarded the compensation considering the quality of those lands. However, as far as the petitioners are concerned, S.L.A.O. has not applied the same yardstick while awarding the compensation. In order to substantiate the petitioners' claim about fertility and quality of the acquired land, it is absolutely necessary to appoint the Court Commissioner. In support of his submissions, he relied upon Sections 9 and 23 of the Act as also decision of Apex Court in the case of Special Deputy Collector and another vs. Kurra Sambasiva Rao & Ors., 1997 (6) SCC 41 .
