Rectification under section 154 is barred where dividend-tax liability turns on debatable interpretation rather than an obvious record error.

Section 154 of the Income-tax Act cannot be used to rectify an assessment unless the alleged mistake is obvious, patent, and free from debate. Where dividend-tax liability depended on interpreting the relevant Finance Act language and the Revenue's construction was only one possible view, the omission to tax an earlier dividend amount was not an apparent error on the record; the rectification order could not be sustained and the Tribunal's view that section 154 did not apply was upheld.

Issues: Whether the Income-tax Officer could invoke section 154 to rectify the assessment on the footing that dividend tax on the amount declared for the earlier assessment year had been omitted, or whether the point required debate and was therefore outside the scope of rectification.

Analysis: Rectification under section 154 is confined to obvious and patent mistakes and cannot be used where the issue is capable of more than one view or requires a long drawn process of reasoning. The liability to dividend tax under the relevant Finance Act provisions depended on the interpretation of the expression governing the relevant amount of distributions of dividends, and the Court found that the construction urged by the Revenue was not the only possible view. Since the omission to bring the earlier dividend amount to tax did not disclose an error so obvious as to be apparent on the record, the matter was not fit for rectification under section 154.

Conclusion: The Tribunal was justified in holding that section 154 did not apply, and the rectification order could not be sustained.

Ratio Decidendi: A point cannot be corrected under section 154 of the Income-tax Act, 1961 unless the mistake is manifest, obvious, and not one that depends on debatable interpretation or competing views.
