The Judgment of the Court was delivered by TULZAPURKAR	 J. These two appeals by certificates granted by the High Court of Andhra Pradesh raise the question of legality and or validity of two notices issued by the Assistant Controller of Estate Duty	 Hyderabad	 one under section 59(a) and the other under section 61 of the (hereinafter called 'the Act '). Two parcels of agricultural land (admeasuring 22 Acres 24 Guntas and 8 Acres 23 Guntas) situated in Moosapet village	 belonging to one Rashid Shapoor Chenai were during his lifetime	 acquired for the Synthetic Drugs Project Factory of the Indian Drugs and Pharmaceutical Ltd. by the Andhra Pradesh Government by Notifications issued on June 19	 1961 and January 18	 1962 under the Land Acquisition Act. D Possession of the lands was taken in January 1963 and by two separate awards both made on January 31	 1963 the Special Deputy Collector of Land Acquisition awarded a total compensation of Rs. 20	000. This compensation was received by Rashid himself during his lifetime. Later two more parcels of agricultural land (admeasuring 131 Acres 10 Guntas and 224 Acres 22 Guntas) situated at Qutbillapur in Medchal Taluk belonging to Rashid where acquired for Hindustan Machine Tools	 Units I and II by the Andhra Pradesh Government by Notifications issued on November 1	 1963 and February l	 1964 under the Land Acquisition Act. Though the former notification was issued during his lifetime and the latter after death	 possession of both the lands was taken after his death by the Government on December 4	 1963 and March 15	 1964 and by two separate awards made on March 12	 1965 and March 19	 1965	 the Special Deputy Collector awarded a total compensation of Rs. 4	29	360. This compensation was received in April ]965 by the heirs of Rashid	 namely	 his widow Mrs. Freny Chenai and son Shapoor Rashid Chenai on whom the estate of Rashid devolved in equal shares. On the death of Rashid on November 4	 1963	 Mrs. Freny Chenai (the appellant in C.A. No. 2206 of 1972) as his widow and the 'accountable person ' filed before the respondent on December 26	 1963 on account of the properties passing on the death of her husband under section 53(3) of the Act. The estate duty assessment was completed by the respondent on March 29	 1966. With regard to the lands acquired both during the lifetime of Rashid as well as after their values 320 were taken at the respective figures of compensation (Rs. 20	000 and Rs. 4	29	360) awarded for them by the Special Deputy Collector. Unfortunately	 within two years of his father 's death	 Shapoor Rashid Chenai (the son) died on May 7	 1965. As stated earlier he had one half share in the undivided estate of his late father Rashid. As required by s.53 of the Act	 (Mrs. Khorshed Chebai) (the appellant in C.A. No. 2205/1972) as his widow and the 'accountable person ' filed before the respondent on November 6	 1965 on account of the properties passing on the death of her husband and the Respondent completed the estate duty assessment on December 30	 1966. In making this assessment also the respondent as in the case of estate duty assessment in respect of the properties passing on the death of Rashid	 adopted the values of the lands acquired by the Government at figures awarded by the Special Deputy Collector for those lands. It appears that the legal heirs of Rashid did not accept the awards made by the Special Deputy Collector in respect of the aforesaid lands and requested the Special Deputy Collector to refer the question of compensation to Civil Court under s.18 of the Land Acquisition Act. References were	 accordingly	 made and the Civil Court by its order dated March 6	 1967 enhanced the compensation awarded by the Special Deputy Collector in respect of Moosapet land by Rs. 1	90	000 and by its order dated October 30	 1967 enhanced the compensation in respect of Qutbillapur lands by Rs. 20	45	000. The Government did not accept the decisions of the Civil Court and filed appeals to the High Court challenging the enhancement	 which appeals are still pending in the High Court. On receipt of information that enhanced compensation was awarded by the Civil Court in respect of the above lands the respondent issued two notices both dated November 14	 1969	 one addressed to Mrs. Khorshed Shapoor Chenai and the other to Mrs. Freny Rashid Chenai. The former notice was issued under section 59(a) of the Act calling upon Mrs. Khorshed Chenai to show cause why the estate duty assessment made on December 30	 ]966 should not be reopened and revised in view of the extra compensations awarded by the Civil Court in respect of the lands acquired by the Government	 while the latter notice was issued under section 61 of the Act requiring Mrs. Freny Chenai to show cause why the mistake apparent from the record should not be rectified and the enhanced compensation included in the principal value of the estate. These notices were challenged by the recepients by filing writ petitions in the High Court. The notice under section 59(a) of the Act issued for the reopening of the assessment completed on December 30	 1966 was challenged in 321 writ petition No. 54 of 1970 on two grounds: (a) that after compensation had been awarded by the Special Deputy Collector under section 11 of the Land Acquisition Act the heirs of the deceased Rashid had merely exercised a right to sue for further compensation which was merely a hope or a chance that the compensation might be enhanced	 that such hope or chance could not be elevated to the status of an assets or property and as such not asset or property chargeable to estate duty had escaped assessment and (b) that even assuming that any asset or property chargeable to estate duty had escaped assessment the notice was illegal and without jurisdiction because such escapement was not due to any omission or failure on the part of the. accountable person to disclose fully and truly material facts necessary for making the assessment. As regards the first ground	 the High Court took the view that the right to receive compensation equivalent to market value of the lands on the dates of notifications which sprang directly from the acquisition was "property"	 that no fresh or independent right "to receive extra compensation" accrued to the heirs of the deceased and that since compensation awarded by Special Deputy Collector had been enhanced by Rs. 1	90	000 for the lands acquired for the Synthetic Drugs Project and by Rs. 20	45	000 for the lands acquired for the Hindustan Machine Tools by the Civil Court	 these facts	 which came into existence subsequent to the making of the original assessment	 easily led to the conclusion that the values adopted by the respondent for these lands were far below their real and true market value and as such property (meaning lands) chargeable to estate duty having been under valued had escaped assessment of the duty. On the second aspect the High Court held that the fact that land References were filed against the awards of the Special Deputy Collector under section 18 of the land Acquisition Act and were pending in the Civil Court was not disclosed by the account. able person	 that the said fact was a primary and material fact and not an inferential fact and its non disclosure amounted to omission or failure which could lead the assessing authority to a reasonable belief that property chargeable to estate duty had escaped assessment and as such the respondent had jurisdiction to issue the notice. In this view of the matter	 the High Court upheld the notice issued under section 59(a) of the Act and dismissed the writ petition. This decision of the High Court is being challenged before us in Civil Appeal No. 2205 of 1972. The issuance of the notice under section 61 of the Act was challenged in Writ Petition No. 4059 of 1969 principally on three grounds: (i) that the accountable person had only a claim lo get an extra compensation which was an inchoate right which could not be called 'property ' and whether that claim amounted to a right to property capable of sale in open market was a highly debatable question and a mistake which had 322 to be discovered after lengthy discussion and debate could not be said ' to be a mistake apparent on the record	 (ii) that land acquisition proceedings and land References in Civil Court not being part of the assessment record a mistake discovered by reference to such other record was not a mistake apparent from the record of the case and (iii) that the extra compensation received by the legal heirs of Rashid belonged to them and not to the deceased and hence it was not property that passed on the death of the deceased and	 therefore	 no property escaped assessment. In other words	 under the guise of rectification	 the enhanced compensation could not be taken into account and	 therefore	 the impugned notice was illegal and without jurisdiction. The High Court negatived the contentions and upheld the impugned notice. This decision is challenged in Civil Appeal No. 2206 of 1972. Dealing first with C.A. No. 2205 of 1972	 wherein the notice issued under s.59(a) of the Act has been challenged	 counsel for the appellant raised three contentions against the view taken by the High Court. At the out set counsel pointed out that so far as the estate duty assessment in respect of the properties passing on the death of Shapoor was concerned	 the respondent as well as the High Court had proceeded on the wrong assumption that the acquired lands formed part of the estate of the deceased and passed on his death	 for	 it was on such basis that the High Court held that having regard to the enhanced compensation granted by the Civil Court for the lands such property (meaning lands) had been undervalued in the original assessment and as such it had escaped assessment to duty. According to him the lands no longer formed part of the estate of the deceased at the date of his death	 namely	 on May 7	 1965	 inasmuch as long prior thereto they had vested in the Government	 and	 therefore	 it was merely the right to receive compensation	 which	 if at all	 could constitute property passing on the death of the deceased.	 but he contended that during the lifetime of the deceased the lands in question had not merely been acquired but even the compensation as determined under the awards made by the Special Deputy Collector was paid to and received by the deceased and hence at the time of the death the initial right to receive compensation had already merged in those awards and the only right which the deceased had was the right to agitate against the correctness of the awards and nothing more and this right to claim further compensation was a precarious right	 being merely a right to litigate a chancy and dicey right	 which could not be elevated to the status of any asset or property and as such there was no question of any property having escaped the assessment to duty. It was urged that such a right to further compensation would become property only when the claim would be accepted ' 323 finally by the Court and till the enhanced compensation became payable by reason of final adjudication of the Court no property could be said tc have come into existence and certainly it was not in existence at the date of death. It was pointed out that against the decrees passed by the City Civil Court appeals had been preferred by the Government to the High Court and even the High Court 's decision might be carried in further appeal to this Court and	 therefore	 till the claim was finally accepted by the highest Court no property (enhanced compensation) could be said to have come into existence. Counsel urged that it would run counter to all principles of direct taxation to regard the amount decreed subsequently by the final Court as property having come into existence retrospectively on the relevant date (being date of death under Estate Duty Act and valuation date under the Wealth Tax Act) though	 in fact	 it did not exist on that date	 and in this behalf reliance was placed upon the decision of the Andhra Pradesh High Court in Khan Bahadur Ahmed Alladin & Sons. vs Commissioner of Income tax	 two decisions of the Calcutta High Court	 namely	 Commissioner of Wealth Tax	 West Bengal (II) vs U.C. Mahatab and Commissioner of Income Tax	 West Bengal II vs Hindustan Housing and Land Development trust Ltd. two decisions of the Gujarat High Court	 namely	 Topandas Kundanmal vs Commissioner of Income tax and Addl. Commissioner of Income Tax	 Gujarat vs New Jehangir Vakil Mills Co. Ltd. and one decision of the Kerala High Court in M. Jairam vs Commissioner of Income Tax	 Kerala. Secondly	 counsel contended that assigning that the right to receive compensation survived and it was that right which was being prosecuted by the heirs of Rashid in Civil Court	 the impugned notice had not been issued on the ground that such right to compensation had been undervalued on the earlier occasion and required to be properly valued as at the date of the death but the basis on which it was issued was clearly unsustainable in law P inasmuch as the respondent had issued it on the assumption that there had been escapement of assessment to duty because the lands in the original assessment had been undervalued in view of the glaring enhanced compensation awarded by the Civil Court	 and the High Court 's decision upholding the issuance of such notice on the wrong basis was liable to be set aside. Thirdly	 counsel contended that seeking References under the Land Acquisition Act and their pendency in Civil 324 Court could not be said to be primary facts	 non disclosure of which could amount to an omission or failure on the part of the accountable person resulting in escapement of assessment to duty. On the other hand counsel for the Revenue pressed for our acceptance the view taken by the High Court. He fairly conceded that the lands in question could not be regarded as forming part of the estate of the deceased on the relevant date inasmuch as the lands had vested in the Government long prior to the death of the deceased	 but he contended that upon such acquisition of lands	 the right to receive compensation at market value on the dates of the relevant notifications accrued to the deceased and such right was unquestionably property which would pass on the death of the deceased. He disputed that this right to receive compensation got merged in the awards made by the Special Deputy Collector or that thereafter such right ceased to exist. According to him if the awards made by the Special Deputy Collector had been acquiesced in and accepted without any protest by the deceased or his heirs	 such right would have merged in the said awards	 but where	 as in the case here	 the awards made by the Special Deputy Collector	 which in law are nothing but offers made by the Government to the claimant	 are not accepted or are accepted under protest and the claimant seeks land References in Civil Courts	 the right to compensation must be regarded as having survived or kept alive by the claimants and it is that property (right to compensation) which will have to be evaluated by the assessing authority as; on the date of death. According to him obviously this asset or property had not been correctly valued in the original assessment proceedings inasmuch as glaring enhancement had been granted by the Civil Courts in the land References and	 therefore	 there was escapement of assessment to duty	 and hence the notice under section 59(a) of the Act should be regarded as having been issued properly. Counsel further contended that the High Court had rightly taken the view that seeking References under the Land Acquisition Act and their pendency in Civil Court were primary facts which had not been disclosed by the accountable person during the original assessment and such non disclosure led to the reasonable belief that there was escapement of assessment to duty. The impugned notice according to him	 therefore	 was relied and justified. As stated above	 so far as the estate duty assessment in respect of the properties passing on the death of Shapoor was concerned	 counsel for the Revenue fairly conceded that the lands which were the subject matter of acquisition proceedings could not be regarded as forming part of the estate of the deceased on the relevant date and could not pass on his death inasmuch as those lands had vested in the Government 325 long prior to his death but the right to receive compensation at market value on the dates of the relevant notifications unquestionably accrued to the deceased which was property and it would be such property that would pass on the death of the deceased. That such right is property is well settled and if necessary reference may be made to a decision of this Court in Pandit Lakshmi Kant Jha vs Commissioner of Wealth Tax	 Bihar and Orissa	 a case under the where it has been clearly held that the right to receive compensation in respect of the Zamindari estate which was acquired by the Government h 	 under the Bihar Land Reforms Act	 1950	 even though the date of payment was deferred	 was property and constituted an asset for the purpose of that taxing statute. In other words	 since the lands were lost to the estate of the deceased before the relevant date	 namely	 the date of death	 it would be the right to receive compensation under the Land Acquisition Act that will have to be evaluated under the Estate Duty Act. Counsel for the appellant did not dispute this position but he contended that no sooner the Collector (the Special Deputy Collector here in) made his awards determining the amounts of compensation payable to the claimants under sec. 11 of the Land Acquisition Act	 the right to receive compensation must be regarded as having merged in the awards	 the determination having been made by a statutory public official and what the claimants would be left with thereafter was merely a right to agitate the correctness of such determination and this right to claim further compensation being merely a right to litigate was no asset or property and further that such right would become asset or property only after the Civil Court finally adjudicated upon such claim. The High Court	 while negativing this contention	 has held that the "right to receive extra compensation" was not a separate or different right independent of "the right to receive compensation". It has observed thus: "The right to receive compensation for the lands acquired by the Government	 at their market value at the date of the acquisition is one and indivisible right. There is no right to 'receive compensation ' and a separate right to receive 'extra compensation '. The only right is to receive the compensation for the lands acquired by the Government	 which is the fair market value on the date of acquisition. The argument of learned counsel that the right to receive extra compensation accrued when the Civil Court passed the order and not before does not merit acceptance. The 326 so called right to receive extra compensation cannot be torn from or considered separately from the right to receive the market value of the lands acquired by the Government. That right accrues to the owner of the lands as soon as the lands are acquired by the Government. It is	 therefore	 difficult to accept the argument of the learned counsel for the petitioner that a fresh and an independent right to 'receive extra compensation ' accrue to the heirs of the deceased and that it was owned and possessed by the heirs of the deceased." In our opinion the High Court was right in holding that there are no two separate rights one a right to receive compensation and other a right to receive extra or further compensation. Upon acquisition of his lands under the Land Acquisition Act the claimant has only one right which is to receive compensation for the lands at their market value on the date of the relevant notification and it is this right which is quantified by the Collector under s.11 and by the Civil Court under s.26 of the Land Acquisition Act. It is true that under s.11 the Collector after holding the necessary inquiry determines the quantum of compensation by fixing the market value of the land and in doing so is guided by the provisions contained in sections 23 and 24 of Act the very provisions by reference to which the Civil Court fixes the valuation. It is also true that the Collector 's award is	 under s.12	 declared to be	 except as otherwise provided	 final and conclusive evidence as between him and the persons interested. Even so	 it is well settled that in law the Collector 's award under s.11 is nothing more than an offer of compensation made by the Government to the claimants whose property is acquired (vide Privy Council decisions in Ezra vs Secretary of State for India and this Court 's decision in Raja Harish Chandra vs Dy. Land Requisition Officer and Dr. G. H. Grant vs State of Bihar. If that be the true nature of the award made by the Collector then the question whether the right to receive compensation survives the award must depend upon whether the claimant acquiesces therein fully or not. If the offer is acquiesced in by total acceptance the right to compensation will not survive but if the offer is not accepted or is accepted under protest and a land reference is sought by the claimant under s.18	 the right to receive compensation must be regarded as having survived and kept alive which the claimant prosecutes in Civil Court. It is impossible to accept the contention that no sooner the Collector has made his award under s.11 the right to compensation is destroyed or ceases to exist or is merged in the award	 or what is left 327 with the claimant is a mere right to litigate the correctness of the award. The claimant can litigate the correctness of the award because his right to compensation is not fully redeemed but remains alive which he prosecutes in Civil Court. That is why when a claimant dies in a pending reference his heirs are brought on record and are permitted to prosecute the reference. This	 however	 does not mean that the Civil Court 's evaluation of this right done subsequently would be its valuation as at the relevant date either under the Estate Duty Act or the Wealth Tax Act. It will be the duty of the assessing authority under either of the enactments to evaluate this property (right to receive compensation at market value on the date of relevant notification) as oh the relevant date (being the date of death under the Estate Duty and valuation date under the Wealth Tax Act). Under s.36 of the Estate Duty Act the assessing authority has to estimate the value of this property at the price which it would fetch if sold in the open market at the time of the deceased 's death. In the case of the right to receive compensation	 which is property	 where the Collector 's award has been made but has not been accepted or has been accepted under protest and a reference is sought or is pending in Civil Court at the date of the deceased 's death	 the estimated value can never be below the figure quantified by the Collector because under section 25(1) or the Land Acquisition Act	 Civil Court cannot award any amount below that awarded by the Collector; the estimated value may be equal to the Collector 's award or more but can never be equal to the tall claim made by the claimant in the Reference nor equal to the claim actually awarded by the Civil Court inasmuch as the risk or hazard of litigation would be a detracting factor while arriving at a reasonable and proper value of this property as on the date of the deceased 's death. The assessing authority will have to estimate the value having regard to the peculiar nature of the property	 its marketability and the surrounding circumstances including the link or hazard of litigation looming large at the relevant date. The first contention of counsel for the appellant	 therefore	 fails. The second contention urged by the counsel for the appellant	 however	 appears to us to be well founded and the impugned notice issued under s.59(a) of the Act will have to be quashed on that ground. As we have said	 above	 since in the instant case the wards made by the Special Deputy Collector were not accepted by the heirs of the deceased and Land References were sought by them and the same were pending in Civil Court at the relevant date (being the date of Shapoor 's death) the notice under s.59(a) would have been valid if the same had been issued on the basis that such right to compensation had been undervalued on the earlier occasion and required to be properly valued as on 328 the date of the death	 but what we find is that the said notice was issued by the respondent on the wrong assumption that the acquired lands still formed part of the estate of the deceased and that having regard to the glaring enhanced compensation granted by the Civil Court for the lands	 the said lands had been undervalued in the original assessment and as such the same had escaped assessment to duty. In the notice issued to the appellant under s.59(a) of the Act a bald statement was made by the respondent to the effect that he had reason to believe that property chargeable to estate duty (a) had escaped assessment and (b) had been under assessed	 and	 therefore	 the appellant was called upon to deliver a further statement of Account. By her Chartered Accountant 's letter dated December 15	 1969 the respondent was called upon to give the basis for his aforesaid belief	 to which the respondent re plied on January 1	 1970 thus: "The extra compensations received by you in O. P. No. 325/65	 O.P. No. 364/65	 O.P. No. 29/64 and O.P. No. 30/64 relating to the land acquired by the Government escaped assessment. In view of your failure to disclose full particulars to Department regarding the land acquisition proceedings in the Account filed by you	 reassessment proceeding have been initiated under s.59(a) of the Estate Duty Act. " The aforesaid communication clearly brings out the fact in the respondent 's view the extra compensation (meaning the enhanced amounts) received by the appellant under the Civil Court decrees in Land References had escaped assessment in the earlier assessment proceedings and since such escapement was due to the appellant 's failure to disclose full particulars regarding the land acquisition proceedings	 the reassessment proceedings were being initiated. In other words	 the assessment was being reopened for the purpose of including the enhanced amounts received by the appellant is the principal value of the property passing on the death and assessing the same to duty and not for the purpose of evaluating the right to compensation which had been undervalued on the earlier occasion. Further	 as regards the basis on which the impugned notice had been issued the High Court took the following view while upholding the issuance of the notice: "Then	 the next question that arises is whether such non disclosure resulted in an under valuation of the properties included in the account	 and consequently there was an escapement of the property chargeable to the estate duty from assessment ? The compensation awarded by the Special Deputy 329 Collector has been enhanced by Rs. 20	45	000 in the case of lands acquired for H.M.T. and by Rs. 1	90	000 for the land acquired for the Synthetic Drugs Project. Those facts which came into existence subsequent to the making of the assessment	 lead to the conclusion that the values adopted by the Asst. Controller of Estate Duty for those lands were far below their real and true market value. " x x x x x x x x x x x x x x x x x x "In the instant case	 the enhancement by the City Civil Court of the compensation awarded by the Special Deputy Collector was so large that no reasonable person could say that the values adopted by the Asst. Controller of Estate Duty of those lands on the basis	 of the awards made by the Special . Deputy Collector	 represented their true and correct market values. No attempt has ever been made by the Accountable person to show that the values adopted by the Asst. Controller Estate Duty represented their true and correct market values. In those circumstances	 an inevitable conclusion flows that there was under valuation of the properties which were included in the account. " The aforesaid observations of the High Court as well as the contents of the communication sent by the respondent to the appellants representative on January 9	 1970	 clearly suggest that the impugned notice had been issued on the basis that the acquired lands still formed part of the state of the deceased which passed on his death	 that the valuation for those lands adopted on the earlier occasion which was on the basis of compensation awarded by the Special Deputy Collector did not represent their correct market value which was clear from the glaring enhanced compensation that was awarded by the Civil Court under its decrees in Land References and	 therefore	 such property had escaped assessment to duty. In other words	 the reassessment was intended to be undertaken with a view to include the enhanced amounts received by the appellant in the principal value of the property passing on death and bringing the same to duty. We were informed at the Bar by counsel for the appellant that in the reassessment which was made pursuant to the impugned notice	 the quantum of extra compensation decreed by the Civil Court was included in the assessment and brought to duty. obviously	 the impugned notice which was issued on a wrong basis and with the aforesaid objective and the subsequent reassessment made in pursuance thereof would be clearly illegal and unsustainable inasmuch 330 as the extra compensation awarded by the Civil Court taken with the	 original compensation awarded by the Special Deputy Collector cannot be regarded as proper evaluation of the right to receive compensation as on the date of the death of the deceased. Proposed as well as actual inclusion of such extra compensation awarded by the Civil Court in the principal value of the estate passing on the death of the deceased would be manifestly wrong for more than one reason. In the first place the said property	 namely	 the enhanced compensation was not in existence 1. at the date of the death of the deceased. Secondly	 such extra compensation awarded by the City Civil Court was liable to variation in the appeals that were pending in the High Court. Thirdly)	 as discussed above	 such extra compensation together with the compensation awarded by the Special Deputy Collector could not be regarded as the proper valuation of the right to compensation as on the relevant date (the date of the deceased 's death). In our view	 therefore	 the very issuance of the notice under s.59(a) which was done on a basis clearly unsustainable in law is liable to be quashed on this ground. Consequently	 reassessment which has been made by the Respondent	 is also liable to be quashed. In view of the aforesaid conclusion	 it is unnecessary for us to deal with the last contention urged by the counsel for the appellant that seeking of land References and their pendency in Civil Court were not primary facts but inferential facts and non disclosure thereof would not amount to failure or omission on the part of the accountable person to disclose full particulars leading to escapement of assessment to duty. In the result the appeal is allowed and the impugned notice issued under s.59(a) of the Act as also the subsequent reassessment made are quashed. The Revenue will pay the costs of the appeal to the appellant Turning to Civil Appeal No. 2206 of 1972	 counsel for the appellant challenged the impugned notice issued under s.61 of the Act on two grounds: (a) it was case of change of opinion as regards the valuation of lands acquired and not a case of mistake apparent from the record and as such the impugned notice was issued under s.61 with a view to get over the bar of limitation under s.73A	 which would otherwise be applicable to a notice under s.59(a) of the Act and (b) that for purposes of section 61 the land acquisition proceedings and Land References in the Civil Court could not be regarded as part of the assessment record and he so called mistake discovered by reference to such other record was not a mistake apparent from the record of the case and as such the 331 impugned notice was liable to be quashed. In our view	 the first ground is sufficient to dispose of the appeal. The impugned notice dated November 14	 1969 in terms recites that the assessment in this case was completed on March 29	 1966 on a net principal value of Rs. 23	53	064 (which included the value of the acquired lands at rates fixed by the Land Acquisition officer) with a duty worked out at Rs. 5	07	919.20	 that it was then learnt that in respect of the acquired lands the Civil Court had enhanced the compensation fixed by the Land Acquisition officer and had ordered payment thereof with interest at 4% (particulars whereof were specified) and that	 therefore	 the respondent proposed "to rectify the assessment under section 61 as mistake apparent from the record and adopt the above enhanced compensation awarded by the Court". It is thus clear that the rectification is being undertaken on the ground that the initial valuation adopted in respect of the acquired lands was based at rates fixed by the 'Land Acquisition. Officer	 that such valuation was obviously wrong in view of the enhanced compensation awarded by the 	 Civil Court and	 therefore	 the enhanced compensation was sought to be included in the principal value of the estate by undertaking the rectification proceedings. In substance it cannot be said to be a case of rectification of any mistake apparent from the record but the respondent is really seeking to change his opinion about the valuation of the acquired lands because some other authority	 namely the Civil Court has valued the same differently. Now	 for the purpose of enhancing the value of the acquired lands on the. basis of their value. as determined by the Civil Court the respondent must resort to provisions of section 59 and proceed to make reassessment but such reassessment has to be done within the period of three years from the date of the original assessment under section 73 A of the Act. It seems to us that in the instant case the respondent resorted to s.61 because the rectification of any mistake apparent from the record could be done at any time within five years from the date of the original assessment. In Ethel Rodrigues vs Assistant Controller of Estate Duty	 Estate Duty	 Estate Duty cum Income tax Circle	 Mangalore	 on similar facts when the Assistant Controller of Estate Duty	 Bangalore had issued a notice purporting to act under s.61 of the Act on the ground that the estate had been valued at an enhanced figure in the probate proceedings and had in proceedings undertaken pursuant to such notice enhanced the valuation of the estate in accordance with its valuation placed on the estate in the probate proceedings and consequently enhanced the estate duty	 this Court quashed the order of rectification. The principle enun 332 ciated by this Court in that case has been succinctly summarised in the head note thus: "Where the Controller has made his own valuation of the estate of a deceased person under section 36 of the 	 he has no jurisdiction to rectify the assessment under section 61 on the ground that the estate has been taken at an enhanced value in the probate proceedings. taking the enhanced value put upon the estate in the probate proceedings he cannot be said to rectify any mistake apparent from the record of the estate duty assessment but he would be changing his opinion about the valuation of the valuation of cause some other authority has valued the estate differently. For the purpose of section 61	 the only record that the assessing authority can look into is the record relating to the assessment of estate duty and not any other record such as the be cord in the probate	 proceedings which is not relevant. For the purpose of enhancing the value an estate on the basis of the value taken in the probate proceedings the Controller has to. invoke the Provisions of section 59 and proceed to reassess and for such a reassessment the bar provided in section 73 A will operate. " In our view	 the facts of the instant case clearly come within the ratio of the aforesaid decision. The High Court has attempted to distinguish the above decision by stating that in the instant case the res respondent had merely accepted the value of the acquired lands as determined by the Special Deputy Collector in his award and the accountable person had no objection to this course and	 therefore	 the respondent himself did not estimate the market value of the lands on the date of death of Rashid and as such it was not a case of change of opinion on his part as regards the correct valuation of the lands. It is difficult to accept this view. It cannot be disputed that when the original assessment was made it was the duty of the respondent	 after scrutinising the Account filed and examining the materials produced before him	 to value the estate of the deceased properly under s.36 of the Act and when he accepted the compensation fixed by the Special Deputy Collector as the proper valuation he must be deemed to have adopted that evaluation as his own estimated value of the lands which he wanted to enhance by relying upon the valuation made by the another authority	 namely	 the City Civil Court. To such a case s.59 is clearly attracted but obviously with a view to avoid the bar of section 73 A he purported to. issue the impugned notice under s.61 and therefore the same is liable to be quashed. The aforesaid decision seems to lend support to the 333 second ground urged by counsel for the appellant for quashing the impugned notice but we would like to base our decision on the first ground discussed above. In this case also we are told that the rectification proceedings have been completed pursuant to the impugned notice	 which also must be quashed. In the result	 the notice under s.61 of the Act and the rectification order passed in pursuance thereof are quashed. The Revenue will pay the costs of the appeal to the appellant. V.D.K. Appeals allowed.

The Andhra Pradesh Government acquired the lands belonging to one Rashid Shapoor Chenai and situate at Moosapet Village Hyderabad and Qutbillapur in Medchal district. The special Deputy Collector of Land Acquisition awarded a total compensation of Rs. 20	000 and Rs. 4	29	360 respectively. The compensation of Rs. 20	000 was paid during the life time of Rashid and the compensation of Rs. 4	29	360 was paid after Rashid 's death to his widow Mrs. Freny Chenai and son Shapoor Rashid Chenai on whom the estate of Rashid devolved in equal shares. On the death of Rashid on November 4	 1963	 Mrs. Freny Chenai (appellant in CA 2206/72) as his widow and 'accountable person ' filed before the Respondent on December 26	 1963 an account of the properties passing on the death of her husband under section 53(3) of the Act. The estate duty assessment was completed by the respondent on March 29	 1966. With regard to the lands acquired both during the lifetime of Rashid as well as after	 their values were taken at the respective figures of compensation (Rs. 20	000 and Rs. 4	29	360) awarded for them by the special Deputy Collector. Shapoor Rashid Chenai	 who had one half share in the undivided estate of his late father Rashid died on May	 7	 1965. As required by section 53 of the Act Mrs. Khorshed Chenai (appellant in CA 2205/72) as his widow and the 'accountable person 's filed before the respondent on November 6	 1965 an account of the properties passing on the death of her husband and the respondent completed the estate duty assessment on December 30	 1966. Even here. the respondent adopted the values of the lands acquired by the Government at figures awarded by the special Deputy Collector. The legal heirs of late Rashid did not accept the awards by the special Deputy Collector in respect of the lands acquired by Government and a reference was made to Civil Court under section 18 of the Land Acquisition Act. The Civil Court	 by its orders dated March 6	 1967/Oct. 30	 1967 enhanced the compensation awarded by the special Deputy Collector by Rs. 1	90	000 in respect of Moosapet lands and by Rs. 20	45	000 in respect of Qutbillapur Lands. The Government did not accept the decisions of the Civil Court and filed appeals to the High Court challenging the enhancement	 which appeals are still pending in the High Court. 316 On receipt of information that enhanced compensation was awarded by the Civil Court in respect of the above lands the respondent issued two notices both dated November 14	 1969	 one addressed to Mrs. Khorshed Shapoor Chenai and the other to Mrs. Freny Rashid Chenai. The former notice was issued under section 59(a) of the Act calling upon Mrs. Khorshed to show cause why the Estate Duty assessment made on December 30	 1966 should not be reopened and revised in view of the extra compensations awarded by the Civil Court in respect of the lands acquired by the Government	 while the latter notice was issued under section 61 of the Act requiring Mrs. Freny Chenai to show cause why the mistake apparent from the record should not be rectified and the enhanced compensation included in the principal value of the estate. These notices were challenged by the recipients by filing writ petitions in the High Court. The High Court negatived the contentions raised in both the writ petitions upheld the impugned notices and dismissed the writ petitions. Hence the two appeals by certificates. Allowing the appeals	 the Court	 ^ HELD: 1. So far as the estate duty assessment in respect of the properties passing on the death of Shapoor was concerned	 the lands which were the subject matter of acquisition proceedings could not be regarded as forming part of the estate of the deceased on the relevant date and could not pass on his death in as much as these lands had vested in the Government long prior to his death but the right to receive compensation at market value on the dates of the relevant notifications unquestionably accrued to the deceased which was property and it would be such property that would pass on the death of the deceased. In other words	 since the lands were lost to the estate of the deceased before the relevant date	 namely	 the date of death	 it would be the right to receive compensation under the Land Acquisition Act that will have to be evaluated under the Estates Duty Act. [324 G H	 325 A	 C] Pandit Lakshmi Kant Jha vs Commissioner of Wealth Tax	 Bihar and Orissa	 	 applied. There are no two separate rights one a right to receive compensation and other a right to receive extra or further compensation. Upon acquisition of his lands under the Land Acquisition Act the claimant has only one right which is to receive compensation for the lands at their market value on the date of the relevant notifications and it is this right which is quantified by the Collector under section 11 and by the Civil Court under section 26 of the Land Acquisition Act. It is true that under section 11 the Collector after holding the necessary inquiry determines the quantum of compensation by fixing the market value of the land and in doing so is guided by the provisions contained in sections 23 and 24 of the Act the very provisions by references to which the Civil Court fixes the valuation. It is also true that the Collector 's award is	 under section 12	 declared to be	 except as otherwise provided	 final and conclusive evidence as between him and the persons interested. Even so	 it is well settled that in law the Collector 's award under section 11 is nothing more than an offer of compensation made by the Government to the claimant whose property is acquired. If that be the true nature of the award made by the Collector then the question whether the right to receive compensation survives the award must depend upon whether 317 the claimant acquiesces therein fully or not. If the offer is acquiesced in by total acceptance the right to compensation will not survive but if the offer is not accepted or is accepted under protest and a land reference is sought by the claimant under section 18	 the right to receive compensation must be regarded as having survived and kept alive which the claimant prosecutes in Civil Court. [326 B G] Ezra vs Secretary of State for India ILR ; Raja Harish Chandra vs Dy. Land Requisition Officer	 and Dr. G. H. Grant vs State of Bihar ; 	 followed. It is not correct that no sooner the Collector has made his award under section 11 the right to compensation is destroyed or ceases to exist or is merged in the award	 or what is left with the claimant is a mere right to litigate the correctness of the award. The claimant can litigate the correctness of the award because his right to compensation is not fully redeemed but remains alive which he prosecutes in Civil Court. That is why when a claimant dies in a pending reference his heirs are brought on record and are permitted to prosecute the reference. This	 however	 does not mean that the Civil Court 's evaluation of this right done subsequently would be its valuation as at the relevant date either under the Estate Duty Act or the Wealth Tax Act. It will be the duty cf the assessing authority under either of the enactments to evaluate this property (right to receive compensation at market value on the date of relevant notification) as on the relevant date (being the date of death under the Estate Duty and Valuation date under the Wealth Tax Act). Under section 36 of the Estate Duty Act the assessing authority has to estimate the value of this property at the price which it would fetch if sold in the open market at the time of the deceased 's death. In the case of the right to receive compensation	 which is property	 where the Collector 's award has been made but has not been accepted or has been accepted under protest and a reference is sought or is pending in Civil Court at the date of the deceased 's death the estimated value can never be below the figure quantified by the Collector because under section 25(11 of the Land Acquisition Act. Civil Court cannot award any amount below that awarded by the Collector; the estimated value may be equal to the Collector 's award of more but can never be equal to the tall claim made by the claimant in the Reference nor equal to the claim actually awarded by the Civil Court inasmuch as the risk or hazard of litigation would be detracting factor while arriving at a reasonable and proper value of this property as on the date the deceased 's death. The assessing authority will have to estimate the value having regard to the peculiar nature of the property	 its marketability and the surrounding circumstances including the risk or hazard of litigation looming large at the relevant date. [326 H	 327 A F] 4. The very issuance of the notice under section 59(a) was on a wrong basis; It was issued with the object to include the enhanced amounts received by the appellant in the principal value of the property passing on the death of Shapoor and bringing the same to duty; such notice and the subsequent reassessment made in pursuance thereof would be clearly illegal and unsustainable inasmuch as the extra compensation awarded by the Civil Court taken with the original compensation as on the date of the death of the deceased. Proposed as well as actual inclusion of such extra compensation awarded by the Civil Court in the principal value of the estate passing on the death of the deceased would be manifestly wrong for more than one reason. In the first place the said property. namely	 the enhanced compensation was not in existence at the 318 date of the death of the deceased. Secondly	 such extra compensation awarded by the City Civil Court was liable to variation in the appeals that were pending in the High Court. Thirdly	 such extra compensation together with the compensation awarded by the Special Deputy Collector could not be regarded is the proper valuation of the right to compensation as on the relevant date (the date of the deceased 's death). [330 A D] 5. The notice under section 61 of the Act and the rectification order passed in pursuance thereof if illegal and unsustainable. [333 E] (i) The rectification is being undertaken on the ground that the initial valuation adopted in respect of the acquired lands was based at rates fixed by the Land Acquisition officer	 that such valuation was obviously wrong in view of the enhanced compensation awarded by the Civil Court and	 therefore	 the enhanced compensation was sought to be included in the principal value of the estate by undertaking the rectification proceedings. In substance it cannot be said to be a case of rectification of any mistake apparent from the record but the respondent is really seeking to change his opinion about the valuation of the acquired lands because some other authority	 namely	 the Civil Court has valued the same differently. [331 C E] (ii) For the purpose of enhancing the value of the acquired lands on the basis of their value as determined by the Civil Court the respondent must resort to provisions of section 59 and proceed to make reassessment but such reassessment has to be done within the period of three year from the date of the original assessment under section 73A of the Act. In the instant case the respondent resorted to section 61 because the rectification of any mistake apparent from the record could be done at any time within five years from the date of the original assessment. [331 E.F] (iii) When the original assessment was made it was the duty of the respondent	 after scrutinising the account filed and examining the materials produced before him	 to value the estate of the deceased properly under section 36 of the Act and when he accepted the! compensation fixed by the special Deputy Collector as the proper valuation he must be deemed to have adopted that valuation as his own estimated value of the lands which he wanted to enhance by relying upon the valuation made by the another authority	 namely	 the City Civil Court. To such a case section 59 is clearly attracted but obviously with a view to avoid the bar of section 73A he purported to issue the impugned notice under section 61.
