Revenue-based treatment of firm assessments requires fresh reconsideration when appellate findings remove the profit basis.

When an appellate order converted a firm's assessment from profit to loss, the Income-tax Officer had to reconsider afresh whether section 23(5)(b) of the Indian Income-tax Act could still be applied, because the earlier revenue-based foundation for treating the firm as registered had disappeared. Proviso (d) to section 24(2) was read as an enabling provision limited to years in which the firm was treated as registered under section 23(5)(b); it could not be used as a general power to carry an unregistered firm's loss to the partners' accounts regardless of the Revenue's interest. A writ of mandamus could issue to require the officer to apply the statute correctly and reconsider the matter lawfully.

Issues: (i) Whether, after the Appellate Assistant Commissioner converted the firm's assessment from profit to loss, the Income-tax Officer was bound to reconsider afresh the applicability of section 23(5)(b) of the Indian Income-tax Act. (ii) Whether proviso (d) to section 24(2) permitted the loss of an unregistered firm to be carried to the partners' accounts irrespective of the Revenue's interest, and whether mandamus could issue to compel proper reconsideration.

Issue (i): Whether, after the Appellate Assistant Commissioner converted the firm's assessment from profit to loss, the Income-tax Officer was bound to reconsider afresh the applicability of section 23(5)(b) of the Indian Income-tax Act.

Analysis: The power under section 23(5)(b) depended on the Income-tax Officer's opinion that treating the unregistered firm as registered would yield more revenue than assessing the firm as unregistered. That jurisdiction rested on the existence of a profit assessment. Once the Appellate Assistant Commissioner found a loss and directed modification of the assessments, the foundation of the earlier order under section 23(5)(b) disappeared. The appellate order required the matter to be taken back to the stage before the special treatment of the firm as registered, and the Income-tax Officer had to apply his mind again to the statutory condition governing section 23(5)(b).

Conclusion: Yes. The earlier order under section 23(5)(b) could not stand without fresh reconsideration, and the Income-tax Officer was bound to determine the matter again in the altered circumstances.

Issue (ii): Whether proviso (d) to section 24(2) permitted the loss of an unregistered firm to be carried to the partners' accounts irrespective of the Revenue's interest, and whether mandamus could issue to compel proper reconsideration.

Analysis: Proviso (d) was construed as an enabling provision operating only when, in the year concerned, the firm was to be treated as registered in accordance with section 23(5)(b). The words "during any year" were material and prevented the proviso from being read as a general power to transfer losses to partners whenever that would diminish revenue. The proviso had to be harmonised with the revenue-condition in section 23(5)(b). Since the Income-tax Officers acted under a assumption of law and failed to reconsider the matter as required, the High Court could properly direct them to act according to law by mandamus.

Conclusion: No. Proviso (d) did not authorise ignoring the revenue test, and mandamus was maintainable to compel lawful reconsideration by the Income-tax Officer.

Final Conclusion: The assessments had to be reconsidered in accordance with the correct legal position, and the appellant was entitled to relief requiring the Income-tax Officer to decide the matter afresh; the appeal succeeded with costs as ordered.

Ratio Decidendi: Where an appellate order removes the factual foundation of an Income-tax Officer's earlier exercise of a conditional power, the officer must reconsider that power afresh; a proviso enabling loss carry-forward cannot be read to override the statutory requirement that treatment of an unregistered firm as registered must serve the Revenue's interest.
