Summarize the following court judgment. ivil Appeal No. 1351 of 1976. From the Judgment and Order dated 24.11. 1975 of the Andhra Pradesh High Court in A.S. No. 691 of 1972. T.V.S.N. Chari for the Appellant. A. Subba Rao and A.D.N. Rao for the Respondents. The Judgment of the Court was delivered by K. RAMASWAMY	 J. This appeal by special leave arises against the Division Bench judgment dated November 24	 1975 in A.S. No. 691 of 1972 of the A.P. High Court fixing the market value @ Rs. I0 per square yard. The facts lie in a short compass are stated thereunder. By notification under section 4(1) of the Land Acquisition Act 1894 (in short 'the Act ') was published in the State Gazette on November 21	 1963 to acquire 5 acres 589 1/3 sq. yards in T.S. No. 981	 Block No. 34 of Waitair Ward	 Vishakapatnam for a housing scheme. The Collector 475 awarded at Rs. 1.58 per sq. yard and on reference	 the Civil Court enhanced the compensation to Rs. 10 per sq. yard with solatium at 15 per cent and interest at 4 per cent. The respondent claimed @ Rs. 12 per sq. yard. On appeal and cross appeals the High Court confirmed the award and dis missed the appeal as well as cross objections for enhance ment to Rs. 12 per sq. yard. Two contentions have been raised by Shri Narsimahachari	 the learned counsel for the appellant. Under exhibit B. 6 dated August 3	 1961; under exhibit B 7 dated Sept. 5	 1961 and exhibit B 8	 dated Sept. 8	 1961 the respondent purchased one acre 1936 sq. yards in each docu ments in the same T.S. No. 981 @ 0.42 p. per sq. yard. He sold on January 24	 1963 in an extent of one acre under exhibit B. 10 @ Rs.5 per sq. yard. Therefore	 ' the aforesaid sale deeds	 exhibit B. 6	 B. 7	 B. 8 and B. 10 will reflect the prevailing market value of the land in question. The Trial Court and the High Court committed grievous error in placing reliance on a decision of the High Court in A.S. No. 191 of 1967 dated November 11	 1970 awarding @ Rs. 10 per sq. yard in respect of 6	209 sq. yards in T.S. No. 1008	 Block No. 39	 Waitair Beach Road which was acquired under a notifica tion dated March 19	 1961 for the purpose of Caltex Oil Refinery. The price fixed therein does not reflect the correct market value while the bona fide sale deed of pur chase and sale by the respondents relating to the acquired land are available on records and form correct basis. The courts below committed grave error of law in completely excluding those sale transactions and relying upon that judgment. We find force in the contention	 though Shri Subba Rao	 learned counsel for the respondent vehemently resisted	 it. It is settled law by catena of decisions that the market value postulated in section 23(1) of the Act designed to award just and fair compensation for the lands acquired. The word "market value" would postulate price of the land prevailing on the date of the publication of the notification under section 4(1). This Court repeatedly laid the acid test that in determining the market value of the land	 the price which a willing vendor might reasonably expect to obtain from a willing purchaser would form the basis to fix the market value. For ascertaining the market rate	 the Court can rely upon such transactions which would offer a reasonable basis to fix the price. The price paid in sale or purchase of the land acquired within a reasonable time from the date of the acquisition of the land in question would be the best piece of evidence. In its absence the price paid for a land pos sessing similar advantages to the land in the neighbourhood of the land acquired in or about the time of the notifica tion would supply the data to assess the market value. It is not necessary to cite all the decisions suffice to state that in a recent judgment in Periya & Pareekanni Rubbers Ltd. vs State of Kerala	 [1990] Supp. 1 SCR 476 362 a bench of this Court	 to which one of us K.R.S.	 J.	 was a member surveyed all the relevant precedents touching the points. In the light of the settled legal position let us consider whether the High Court and the Civil Court are justified in excluding the sale deeds completely and to place reliance on another judgment of the Division Bench of the High Court of A.P. Admittedly	 the claimant is a vendee in exhibit B. 6 to B. 8 @ 0.42 paise. In a span of one year and four months	 they sold @ Rs.5 per sq. yard; It is common knowledge that proposal for acquisition would be known to everyone in the neighbourhood	 in particular	 to the owners of the property and it is not uncommon that sale transac tions would be brought into existence before the publication of section 4(1) notification so as to form the basis to lay higher claim for compensation. We do assume that exhibit B. 10 is a genuine and bona fide sale transaction. In respect of one acre of the land in the self same land when sold at Rs.5 per sq. yard	 would it fetch in a short period of nine months	 double the market value	 namely. @ Rs. 10 per sq. yard. We have no doubt that it would not get that price for 5 acres and odd area. It is undoubted that in respect of a notification of 1961 in which another T.S. number in the locality	 namely	 T.S. No. 1008	 ultimately	 the High Court awarded @ Rs. 10 per sq. yard. Perhaps had there been no bona fide or genuine sale transaction relating to the self same land	 the reliance placed on that judgment may be justified but exclusion of bona fide and genuine sale trans actions in respect of the same land under acquisition and to place reliance on the award of some other land is obviously illegal. When the claimants themselves sold as a willing seller of an acre of land @ Rs.5 per sq. yard large extent of five acres and odd under acquisition	 if it is offered to be sold as a block	 it would not fetch higher rate but surely be negotiated for a lesser rate if not the same market value @ Rs.5 due to time lag of nine months. No attempt was made by the respondent to explain under what circumstances they came to sell their lands @ Rs.5 per sq. yard when they expect higher value @ Rs. 10 per sq. yard. May be the payment of Rs. 10 per sq. yard	 be wind fall to the owner of the land in T.S. No. 1008 Taking the totality of the facts and circumstance	 we hold that the High Court committed grave error to completely ignore the sale transac tions of the lands under acquisition. In view of the time lag we have no hesitation to conclude that the prevailing market value of the land as on the date of the notification would be Rs.6 per sq. yard. It is next contended by Shri Narsimahachari that when a large extent of land was acquired for a housing scheme	 at least 1/3 of the land should be deducted towards laying the roads	 setting up parks	 477 drainage and other amenities. The High Court committed manifest error in omitting to deduct 1/3 of the land. Shri Subba Rao	 the learned counsel for the respondent contended that the High Court had noted this contention of the appellant and considered that the market value of the land would be Rs. 12 per sq. yard and after giving the deduction of 1/3 it would come to Rs. 10. The reasoning of the High Court is proper and warrants no interference. In support thereof he placed reliance in Spl. Tehsildar	 Visha kapatnam vs Rednam Dharma Rao & Ors.	 C.A. No 4187 of 1982	 dated July 17	 1990 wherein this Court had upheld the deduc tion of 1/5 from the market value towards developmental charges. It is settled law that the High Court and the Reference court when made wrong application of a principle or important points effecting valuation has been over looked or misapplied	 this Court would under article 136 correct the same	 vide The Spl. Land Acquisition Officer	 Bangalore vs T. Adinarayan Setty	 [1959] Suppl. 1 S.C.R. 404; Dattatrayaya Shankarbhat Ambalgi and Ors. vs The Collector of Sholapur and Anr.	 AiR 3 S.C.C. 431; The Dollar Co.	 Madras vs Collector of Madras	 [1975] Supp. SCC 403 and Padma Uppal Etc. vs State of Punjab & Ors. 	 ; In Tribeni Devi & Ors. vs Collector of Ranchi	 ; at 2 13	 this Court held that "in order to devel op that area at least the value of 1/3 of the land will have to be deducted for roads	 drainage and other amenities". On this basis the value of the land at Rs.2	08	135.70 per acre would	 after the deduction of 1/3 come to Rs. 1	38	757 per acre. In Smt. Kaushalya Devi Bogre & Ors. vs The Land Acquisition Officer	 Aurangabad; 	 this Court held that deduction of 1/3 was held to be reasonable. In Vijay Kumar Motilal vs State of Maharashtra	 19 i/3rd was deducted towards developmental charges in undeveloped area. In Vijaysingh Liladhar vs Special Land Acquisition Officer	 the deduction of i/4th by the High Court which was not challenged in this court was upehld. In Spl. Land Acquisition Officer	 Bangalore vs T. Adinarayan Setty	 supra	 deduction of 25 per cent was held to be reasonable. It is to be noted that in building Regula tions	 setting apart the lands for development of roads	 drainage and other amenties like electricity etc. are condi tion precedent to approve lay out for building colonies. Therefore	 based upon the situation of the land and the need for development the deduction shall be made. Where acquired land is in the midst of already developed land with ameni ties of roads	 drainage	 electricity etc. then deduction of 1/3 would not be justified. In the 478 rural areas housing schemes relating to weaker sections deduction 1/4 may be justified. On that basis	 this court in R. Dharma Rao 's case upheld deduction of 1/5 because the owner while obtaining the lay out had already set apart lands for road and drainage. Therefore	 deduction of 1/3 would be reasonable. In fact in The Tehsildar	 Land Acquisi tion	 Vishakapatnam vs P. Narasing Rao & Ors.	 	 a Division Bench of the High Court surveyed judgments of the High Court relating to housing schemes of Vishakapatnam upholding deduction of 1/3 to be reasonable. Accordingly we hold that 1/3 of the market value should be deducted for development of the lands. The High Court com mitted greivous error in giving a curious reasoning of valuing at Rs. 12 and upholding Rs. I0 to be the market value after deduction	 though *.he market value was deter mined at Rs. 10. Accordingly the appeal is allowed. The market value is determined at Rs.6 per sq. yard and after deducting 1/3 the market value is Rs.4 per sq. yard. The respondents are entitled to 15 per cent Solatium on market value and 4 per cent interest thereon from the date of dispossession. But in the circumstances parties are directed to pay and receive their own costs. N.P.V. Appeal al lowed.

The respondent 's land admeasuring 5 acres 589 1/3 Sq. yards was acquired by the State Government in 1963 for a housing scheme and compensation at Rs.1.58 per Sq. yard was awarded. On reference	 the Civil Court enhanced the compen sation to Rs. 10 per Sq. yard with solatium at 15 per cent and interest at 4 per cent. On appeal and cross appeals	 the High Court confirmed the award. In the appeal before this Court	 on behalf of the De partment	 it was contended that the respondent had purchased the land in question in 1961 in three documents at Rs.0.42 p. per sq. yard and sold in 1963 one acre of the land at Rs.5 per sq. yard and	 therefore	 the deeds under which the transactions took place reflected the prevailing market value of the land in question	 and courts below committed grave error in relying on a decision of the High Court awarding Rs. 10 per sq. yard in respect of another land acquired under a Notification of 1961	 and that when a large extent of land was acquired for a housing scheme	 at least 1/3 of the land should be deducted towards laying the roads	 setting up parks	 drainage and other amenities. Allowing the appeal	 this Court	 HELD: 1.1 The market value postulated in Section 23(1) of the Land Acquisition Act	 1894 is designed to award just and fair compensation for the lands acquired. The word "market value" would postulate price of the land prevailing on the date of the publication of the notifica 473 tion under Section 4(1). In determining the market value of the land	 the price which a willing vendor might reasonably expect to obtain from a willing purchaser would form the basis. For ascertaining the market rate	 the Court can rely upon such transactions which would offer a reasonable basis to fix the price. The price paid in sale or purchase of the land acquired within a reasonable time from the date of the acquisition of the land in question would be the best piece of evidence. In its absence the price paid for a land pos sessing similar advantages to the land in neighbourhood of the land acquired in or about the time of the notification would supply the data to assess the market value. [475E G] Periya & Pareekanni Rubbers Lief. vs State of Kerala	 [1990] Supp. 1 SCR 362	 referred to. 1.2 In the instant case	 admittedly	 the claimant pur chased land at Rs.0.42 p. and in a span of one year and four months	 sold at Rs.5 per sq yard. When the claimants them selves sold as a willing seller of an acre of land @ Rs.5 per sq. yard	 if a large extent of five acres and odd under acquisition is offered to be sold as a block	 it would not fetch higher rate but surely be negotiated for a lesser rate	 if not the same market value of Rs.5 due to time lag of nine months. May be the payment of Rs. 10 per sq yard to the owner of another land acquired in 1961 was a windfall. Taking the totality of the facts and circumstances	 the High Court committed grave error in completely ignoring the sale transactions of the lands under acquisition. In view of the time lag	 the prevailing market value of the land as on the date of the notification would be Rs.6 per sq. yard. [476B	 E G] 1.3 In Building Regulations	 setting apart the lands for development of roads	 drainage and other amenities like electricity etc. are condition precedent to approve lay out for building colonies. Therefore	 based upon the situation of the land and the need for development	 the deduction shall be made. Where acquired land is in the midst of al ready developed land with amenities of roads	 drainage	 electricity etc. then deduction of 1/3 would not be justi fied. In the rural areas housing schemes relating to weaker sections	 deduction of 1/4 may be justified. [477G H	 478A] Spl. Tehsildar	 Vishakapatnam vs Rednam Dharma Rao & Ors.
