"3. After hearing the rival submissions in the light of available material on record and after giving thoughtful consideration thereto, we are of the considered opinion that both Revenue as well as the assessee have to fail in their appeals. When the Assessing Officer has made the best judgment assessment under Section 144 after rejecting (or ignoring) the books of accounts, although audited accounts were produced before him, no addition can be made under section 68 of the Act on account of credits or unsecured loans found recorded in the same very books of account. The Hon'ble Chennai Bench's decision cited supra supports our above finding. When the income is estimated under section 144 of the Act, no separate addition under Section 68 can be validly made when the books of account are rejected/ignored regarding any entry found recorded therein which is deemed to have been ignored/rejected. Therefore, as a necessary corollary of the above premise, no further addition can be made under Section 68 of the Act. In so far as the claim of loss is concerned, in our considered opinion the same cannot be allowed in the absence of any requisite proof thereof. As a result, we dismiss both the appeal as well as the Cross Objection."
