Limitation on tax enhancement prevents reopening issues outside appeal when revision or rectification time has expired.

An assessing officer, while giving effect to an appellate order, cannot enhance the rate of tax on an issue not covered by the appeal after the statutory period for revision or rectification has expired. Matters outside the scope of the appeal may be reopened only through the specific statutory powers available for escaped assessment or rectification, and each power remains confined by its own limitation period. Failure by the assessee to object does not confer jurisdiction or revive a time-barred power. The revised assessment was therefore unsustainable and liable to be cancelled.

Issues: (i) Whether, while giving effect to an appellate order, the assessing officer could enhance the rate of tax on an issue not covered by the appeal after the limitation prescribed for revision or rectification had expired; (ii) Whether the assessee's failure to object to the proposal conferred jurisdiction on the assessing officer to make such enhancement beyond limitation.

Issue (i): Whether, while giving effect to an appellate order, the assessing officer could enhance the rate of tax on an issue not covered by the appeal after the limitation prescribed for revision or rectification had expired.

Analysis: A distinction was drawn between matters actually covered by the appellate order and matters outside the scope of the appeal. Issues not decided in appeal could be dealt with only under the specific statutory powers for escaped assessment or rectification, each of which was subject to its own limitation. The power to give effect to an appellate order under the relevant provision did not permit reopening or enhancing assessment on a separate issue beyond the limitation period. Only where the assessment is set aside and remanded for fresh consideration do all issues reopen, and then the special time-frame applicable to such remand would govern.

Conclusion: The enhancement of the rate of tax was beyond the limitation prescribed for the statutory powers invoked and was not valid.

Issue (ii): Whether the assessee's failure to object to the proposal conferred jurisdiction on the assessing officer to make such enhancement beyond limitation.

Analysis: Jurisdiction to revise or enhance assessment is created and controlled by statute, and it is lost once the limitation period expires. A lack of objection by the assessee cannot revive or enlarge a power that has already become time-barred.

Conclusion: The absence of objection did not confer jurisdiction on the assessing officer.

Final Conclusion: The revised assessment relating to the rate of tax was unsustainable and had to be cancelled, resulting in relief to the assessee.

Ratio Decidendi: Powers to revise, rectify, or enhance assessment must be exercised only within the statutory time-limit applicable to the particular source of power, and an appellate order cannot be used to reopen a separate issue outside the appeal or to bypass limitation.
