The valuation report relied on by the Assessing Officer for making the addition was not a valuation report as contemplated under section 142A of the Act. To make addition on account of difference in cost of construction, the Assessing Officer was duty-bound to reject the books of account and refer the matter to the Departmental Valuation Officer as prescribed under section 142A of the Act, which the Assessing Officer had failed to do so. The registered valuer’s report of the assessee could not be the basis for making the addition which had to be deleted. (AY.2003-04)
