On 14-03-1996, the Income Tax Department issued notices to the appellants stating that the Superintending Engineer, Valuation Cell found that the cost of the construction was around Rs.84,76,000/- and required them to show cause as to why the difference between the cost of construction admitted in the assessment and the value determined by the Superintendent be not treated as unexplained investment under Section 69B of the Act. Reply was filed by the appellants on 20-04-1996 taking an objection to the very attempt to reopen the assessment. Not satisfied with that, the assessing officer required the appellants to file returns for the assessment year 1992-93 and on filing such returns, orders were passed on 20-03-1998 under Section 143(3) read with Section 147 of the Act making an addition of Rs.7,02,760/- each to the income of the appellants. The appellants filed appeals before the Commissioner (Appeals), Range IV, Hyderabad aggrieved by the orders of re-assessment. The appeals were partly allowed through a common order dated 28-05-1999 reducing the figures on the orders of re-assessment to Rs.3,32,420/- to each of the appellants. In the meanwhile, orders of rectification under Section 154 of the Act were passed by the assessing officer by adding a sum of Rs.78,085/- each disallowing the depreciation of 10%.
