3. The learned counsel would submit that instead of considering the reconciliation filed by the petitioner in response to the original notice issued under Section 69 of the Act, which was proposed to treat the alleged purchases as unexplained investment, the respondent, for the first time in the impugned assessment order, invoked Section 69 C of the Act to treat the alleged difference in purchases as unexplained expenditure. The learned counsel further submits that the particulars of the entire amount, which pertains to purchases below Rs.10 Lakhs have been duly uploaded with all the relevant details. However, the impugned order was passed without application of mind. She submits that the petitioner was not given sufficient opportunities to put forth his case on the aspects of 69 C issues, thereby the respondent violated the principles of natural justice. The learned counsel further prayed to remand the matter back to the respondent with liberty to explain her case.
