M. Ramachandran, J.
1. In respect of the assessment years 1996-97, 1997-98 and 1998-99, the assessments of the petitioner, a sea food exporter, stood completed overlooking the objections of the petitioner. Reliance had been placed on [he principles laid down by the Appellate Tribunal in Baby
Marine Eastern Exports’ case. The petitioner submits that for the assessment year 1998-99, the addition of interest on fixed deposits had not been allowed, in spite of the legal position explained to the Tribunal. He submits that the premium received in the course of the export was sale consideration, and it could at the most be treated as part of the sale proceeds, and therefore it deserved deduction. The income from the business, though from different sources, had to be aggregated, according to the petitioner, for quantifying the relief under Section 80HHC of the Act since it had the characteristics of turnover of business and could not have been excluded.
2. As the petitioner felt that these were overlooked, he had filed rectification applications envisaged under Section 154 of the Income-tax Act, 1961. The complaint of the petitioner is that without affording” him an opportunity the petitions had been rejected. Exhibits P-7 to P-9 are the orders and the petitioner challenges these orders complaining that the principles of natural justice stand violated. He ought to have been heard in the matter, and it was improper for the Assessing Officer not to advert to most relevant decisions of the Tribunal which had been placed before him.
3. The question is whether there is justification for this court to interfere at this stage. The assessment orders are normally subjected to appeals at the instance of the assessee. It is submitted that the appeals have already been filed. But nonetheless, the petitioner is aggrieved that his contentions are rejected without justification, and when the errors/omissions had been pointed out, the Assessing Officer should have heard him, as it would have been possible for him to correct the mistakes.
4. I had heard standing counsel for the Department. He opposes the application and submitted that the original petition is not only misconceived, but also is not maintainable. He had referred to Section 154 of the Act. It is possible for the authority to amend an order passed by it, only for exceptional reasons, it is submitted.
5. Being judicial proceedings, an assessing authority has power for rectification of mistakes, both of fact as well as law. But for the only reason that the issue is debatable, proceedings under Section 154 could not be taken. It is shown that errors in assessment due to non-inclusion of income from an entire source, or non-inclusion of certain items are not errors rectifiabte under Section 154 of the Act (see T. Manickavasagam Chettiar v. ITO  35 ITR 482 (Mad)). The mistake pointed out is not an apparent mistake, but only a point of view of the Assessing Officer. Counsel also pointed out the decision laid down in T. S. Balaram, ITO v. Volkart Brothers  82 ITR 50 (SC). A debatable point is outside the purview of Section 154. There was also a suggestion that it was delaying tactics. But this was stoutly opposed by counsel for the petitioner.
6. A right of hearing in all matters could not be read into Section 154. Only when there is enhancement or reduction, or increase in liability, proposed by the order, a hearing is contemplated. Of course, the points urged by the petitioner may be logical, or acceptable at a later stage. But it could not be held that he ought to have been heard before passing of the impugned orders. The petitioner has all his rights reserved for agitating the matter before the appellate forum, and in that sense he cannot be considered as aggrieved by this order. In the circumstances, the original petition is dismissed in limine.
