“Neither the prosecution nor the defence has produced the author of various reports to confirm the valuation. The documents cited in the list of documents is a report signed by two engineers namely S/Shri S.N. Jha and D.N. Mukherjee whereas the document brought on record (Ex. S. 20) has been signed by three engineers. There is also difference in the estimated value of the property in the statement of imputation and the report. The document at Ex. S. 20 has been signed by three engineers and the property has been valued at Rs. 4, 85, 000 for the ground floor and Rs. 2, 55, 600 for the second floor. A total of this comes to Rs. 7, 40, 900 which is totally different from the figure of Rs. 7, 69, 800 indicated in the statement of imputation. None of the engineers who prepared the valuation report though cited as prosecution witnesses appeared during the course of enquiry. This supports the defence argument that the authenticity of this document is in serious doubts. It is a fact that the income tax authorities got this property evaluated by S/Shri S.N. Jha and Vasudev and as per this report at. pp., 50 to_63 they estimated the property at Rs. 4, 57, 600 including the cost of land Rs. 1, 82, 000 for ground and - -. mezzanine floor plus Rs. 2, 55, 600 for first floor and Rs. 20, 000 for cost of land. Thus both the engineers who prepared the valuation report for income tax purposes also prepared the report for the CBI and there is no indication in the subsequent report as to why there is a difference in the value of the property. A perusal of these two reports reveals that there is difference in the specification of the work. The valuation report prepared by Sri S.N. Jha for ground floor for income tax purposes clearly states that the structure was having “RCC pillars at places, brickwork in cement mortar, RCC lintel, 60 cm walls, 9 inch floor height, 17. 6, 8. 00, 8. 00 inch” but in the report for CBI which was also prepared by him the description is “RCC framed structure open verandah on three sides in the ground floor”. Similarly, for the first floor it is written in the report as “partly framed structure and partly load being walls, floor heights 3. 20 mm. Further Shri S.N. Jha on p. 54 of Ex. D. 1 had adopted a rate of Rs. 290 per sq. mtr. for ground floor and adding for extra height he had estimated ground floor including mezzanine floor at Rs. 2, 02, 600. But for the report at Ex. S. 20 the rate has been raised to 365 per sq. mtr. There is no explanation for this increase of rate by Rs. 75 per mtr. It is also observed that for the updating of the cost of index 5% was added to the rate of Rs. 290 as per p. 55 of Ex. D. 1 by Sri S.N. Jha but this has been raised to 97% as an escalation to the cost of index in Ex. S. 20 without explaining or giving the reasons therefor. It is surprising that same set of engineers have adopted different standard for evaluating the same
