Debatable tax interpretation limits rectification, while additional surcharge on exempt income was upheld under the charging scheme.

Additional surcharge was held leviable on a co-operative society's exempt business income under the Finance Act, 1963, because the charging provision extended to residual income and the later Supreme Court interpretation of the same scheme was applied; the issue was decided for the Revenue. Rectification under section 154 was refused because the alleged error depended on a debatable construction of the taxing provision, and section 154 is confined to obvious, patent mistakes not requiring detailed reasoning or open to two reasonable views; this issue was decided for the assessee. The reference was thus answered by upholding the surcharge in principle but denying rectification.

Issues: (i) Whether the levy of additional surcharge on the assessee's exempt business income was in accordance with law; (ii) Whether the alleged error in the levy of additional surcharge was a mistake apparent from the record so as to be rectifiable under section 154.

Issue (i): Whether the levy of additional surcharge on the assessee's exempt business income was in accordance with law

Analysis: The charging provision in Paragraph A of Part I of the First Schedule to the Finance Act, 1963, permitted additional surcharge on the amount of residual income. The Court applied the later Supreme Court ruling on the same statutory scheme and held that additional surcharge could be levied even on income of a co-operative society which was otherwise exempt from income-tax and super-tax under sections 81 and 99 of the Income-tax Act, 1961.

Conclusion: The levy of additional surcharge was in accordance with law and the answer to this issue was in favour of the Revenue.

Issue (ii): Whether the alleged error in the levy of additional surcharge was a mistake apparent from the record so as to be rectifiable under section 154

Analysis: The power under section 154 is confined to obvious and patent mistakes and cannot be used where the question requires a long-drawn process of reasoning or where two views are reasonably possible. The Court found that the construction of the Finance Act, 1963, concerning surcharge on exempt income was not free from doubt, especially in view of conflicting judicial views, and therefore the alleged mistake could not be treated as apparent from the record.

Conclusion: The alleged error was not a mistake apparent from the record and could not be rectified under section 154; this issue was decided in favour of the Assessee.

Final Conclusion: The reference was answered by upholding the legality of the surcharge in principle but rejecting the rectification under section 154, with costs awarded to the Assessee.

Ratio Decidendi: Section 154 cannot be invoked where the alleged error depends on a debatable construction of the taxing provision and two views are reasonably possible; rectification is limited to obvious and patent mistakes.
