Income-tax appeal withdrawal and enhancement powers cannot override the time limit for escaped-income reassessment.

The appellate scheme under the Income-tax Act does not confer an assessee a right to withdraw an appeal so as to defeat the statutory power of enhancement. The appellate authority's enhancement power cannot be frustrated by withdrawal once the appeal is filed. Separately, after the limitation period under section 34 expires, the Assistant Commissioner cannot use the general enhancement power to introduce a new item of income or direct a fresh assessment on that item, because the special reassessment provision is time-bound and confined to escaped income within its statutory scope. The revenue's position failed on both issues, and the assessee succeeded with costs.

Issues: (i) whether an appeal under the Income-tax Act could be withdrawn so as to defeat enhancement proceedings, and (ii) whether, after expiry of the limitation under section 34, the Assistant Commissioner could enhance the assessment by introducing a new item of income or direct a fresh assessment in respect of that item.

Issue (i): whether an appeal under the Income-tax Act could be withdrawn so as to defeat enhancement proceedings.

Analysis: The appellate scheme under sections 30 and 31 of the Income-tax Act is self-contained. While section 31 confers powers of disposal of appeals, including enhancement, the Act contains no provision giving an assessee a right to withdraw an appeal once filed. Recognising such a power would allow an assessee to frustrate the statutory power of enhancement whenever adverse material emerged during the appeal.

Conclusion: The appeal could not be withdrawn as of right by the assessee.

Issue (ii): whether, after expiry of the limitation under section 34, the Assistant Commissioner could enhance the assessment by introducing a new item of income or direct a fresh assessment in respect of that item.

Analysis: Section 34 is a special and time-bound provision dealing only with income that has escaped assessment; it protects the assessee by limiting reassessment to the statutory period. The general power of enhancement under section 31 cannot override the specific limitation and subject-matter restriction in section 34. The appellate authority may deal only with the matter before it and cannot, after the expiry of limitation, bring in a fresh source of income or direct a fresh assessment on that basis.

Conclusion: The Assistant Commissioner had no jurisdiction to enhance the escaped-assessment proceedings by adding the new item or to direct a fresh assessment for that item after limitation had expired.

Final Conclusion: The reference was answered against the revenue on all substantive questions, and the assessee succeeded with costs.

Ratio Decidendi: The general appellate power to enhance an assessment cannot be used to circumvent the specific limitation and confined scope of reassessment under section 34, and no implied right of withdrawal of an income-tax appeal exists where it would defeat the statutory appellate powers.
