The lapse committed by the AO in passing the assessment order without first passing a draft order, against which the assesee may file objections with the DRP, seeking its directions to the AO, is only a procedural irregularity, which does not impinge on the jurisdiction on the AO to pass the assessment order, which he assumes on the issue of notice u/s. 143(2), even as observed by the Hon’ble jurisdictional High Court itself in a number of cases, reference to one of which, i.e., R.V. Sarojini Devi v. IAC [2000] 242 ITR 329 (Mad) stands made in the decision itself (also refer Asst. CIT v. Hotel Blue Moon [2010] 321 ITR 362 (SC)). Reference in this regard may be made to the decision in Daewon Kang Up Co. Ltd. v. DDIT Guduthur Bros. v. ITO [1960] 40 ITR 298 (SC), wherein the Apex Court clarified that the AO assumes jurisdiction to assess on issue of a valid notice, and which obtained till the same remained to be disposed of. The proceedings completed without allowing the assessee an opportunity of being heard was an illegality, vitiating the proceedings, which would relate back in time, having occurred during the course of the assessment proceedings itself. The impugned order was to be set aside, and the proceedings to commence from the stage the illegality or the irregularity had occurred
