Doctrine of merger and statutory interest: omitted interest issues may be revised, and waiver cannot be inferred from silence.

The doctrine of merger was confined to matters actually adjudicated in appeal, so an omitted interest issue that was not appealable could remain open to revision under section 263. Statutory interest under section 217 could be levied after considering any reduction or waiver under rule 40, and a reference to the wrong provision did not defeat the levy where the substantive power existed. Silence in the assessment order did not by itself show that the Income-tax Officer exercised discretion to waive interest under rule 48(1); waiver had to be affirmatively shown.

Issues: (i) Whether the assessment order merged in the appellate order so as to exclude revision under section 263 in respect of interest not considered in appeal; (ii) whether penal interest was leviable under section 217 of the Income-tax Act, 1961, and whether it had to be considered for reduction or waiver under rule 40 of the Income-tax Rules, 1962; (iii) whether the Income-tax Officer should be deemed to have exercised discretionary power under rule 48(1) of the Income-tax Rules, 1922 and waived interest.

Issue (i): Whether the assessment order merged in the appellate order so as to exclude revision under section 263 in respect of interest not considered in appeal.

Analysis: The appellate order was held to absorb only the matters actually adjudicated in appeal. The levy of interest was not a subject-matter of the appeal, and the order levying interest under section 18A(8) of the 1922 Act, or its corresponding provision under the 1961 Act, was not itself appealable. On that footing, the doctrine of merger did not extend to the omitted interest question and the Commissioner could revise that part of the assessment under section 263.

Conclusion: The issue was answered in favour of the Revenue; there was no merger in respect of the interest question and the Commissioner had revisional competence.

Issue (ii): Whether penal interest was leviable under section 217 of the Income-tax Act, 1961, and whether it had to be considered for reduction or waiver under rule 40 of the Income-tax Rules, 1962.

Analysis: The Court treated the omission to levy interest as a matter capable of revision, and held that the proper course was to levy interest under the 1961 Act after considering whether reduction or waiver was warranted under the relevant rule. The fact that the assessment order referred to the wrong provision did not invalidate the levy where the power otherwise existed.

Conclusion: The issue was answered in favour of the Revenue; interest could be charged under section 217 after considering reduction or waiver under rule 40.

Issue (iii): Whether the Income-tax Officer should be deemed to have exercised discretionary power under rule 48(1) of the Income-tax Rules, 1922 and waived interest.

Analysis: The assessment order contained no indication that the Income-tax Officer had applied his mind to the question of interest or exercised discretion to waive it. A silent order was insufficient to justify an inference of waiver, and the Tribunal's factual finding that no such exercise of discretion was shown remained unchallenged.

Conclusion: The issue was answered against the assessee and in favour of the Revenue; no deemed waiver was established.

Final Conclusion: The reference was disposed of by upholding revisional interference on the interest component, sustaining levy of interest under the proper provision, and rejecting the contention that waiver could be inferred from silence in the assessment order.

Ratio Decidendi: The doctrine of merger applies only to matters actually decided in appeal, and an omitted, non-appealable interest issue may be revised independently by the Commissioner; silence in the assessment order does not by itself establish waiver of statutory interest.
