Statutory exemption notification and doctrine of merger determine taxability timing and bar revision under section 263.

A remission arising from a statutory exemption notification takes effect only when the notification is published and made available to the public, not merely from the date it is signed or printed; on that basis, the taxability of the remission fell in the later assessment year. The text also states that the doctrine of merger bars revision under section 263 once an assessment order has merged with an appellate order on matters within appellate jurisdiction, so the revisional authority cannot reopen the merged order. The stated result is that revision was unsustainable and the assessee obtained relief on both timing of taxability and merger.

Issues: (i) Whether the liability remission arising from the exemption notification was taxable under section 41(1) of the Income-tax Act, 1961 in assessment year 1979-80 or only in assessment year 1980-81 upon publication of the notification in the Gazette. (ii) Whether the Commissioner could invoke section 263 of the Income-tax Act, 1961 when the assessment order had merged with the appellate order on matters within the appellate jurisdiction.

Issue (i): Whether the liability remission arising from the exemption notification was taxable under section 41(1) of the Income-tax Act, 1961 in assessment year 1979-80 or only in assessment year 1980-81 upon publication of the notification in the Gazette.

Analysis: The exemption order under the Kerala General Sales Tax Act, 1963 was dated 29-3-1979, but the notification was published and made available to the public only on 3-4-1979. For a notification granting exemption, effectiveness depends on the date on which the public is notified through publication and availability of the Gazette, not merely the date on which the notification is signed or printed. On that basis, the remission of the earlier purchase-tax liability could arise only when the notification became effective on 3-4-1979, which fell in the accounting year relevant to assessment year 1980-81.

Conclusion: The amount could not be brought to tax in assessment year 1979-80 under section 41(1); the assessee succeeded on this issue.

Issue (ii): Whether the Commissioner could invoke section 263 of the Income-tax Act, 1961 when the assessment order had merged with the appellate order on matters within the appellate jurisdiction.

Analysis: The assessment order had already been carried in appeal on some issues, and the Tribunal adopted the view that the doctrine of merger bars revision under section 263 even in respect of matters falling within the appellate authority's jurisdiction but not specifically examined or decided by it. In the absence of contrary binding authority, the revisional power could not be exercised over the merged assessment order.

Conclusion: The Commissioner lacked jurisdiction to revise the assessment under section 263; this issue was decided in favour of the assessee.

Final Conclusion: The revision order was unsustainable and the assessee's relief was upheld on both the timing of taxability and the bar of merger.

Ratio Decidendi: A remission based on a statutory exemption notification becomes effective only when the notification is published and made available to the public, and once an assessment order has merged with an appellate order, section 263 revision is unavailable in respect of that merged order.
