Speculative loss set-off confined to speculative profits only under income-tax law, excluding adjustment against non-speculative business income.

Speculative business losses were held not to be set off against profits from non-speculative business under the Indian Income-tax Act, 1922. The court treated the first proviso to section 24(1) as a substantive provision operating with section 10, intended to prevent speculative losses from reducing taxable income outside speculative . On that construction, speculative loss could be adjusted only against speculative profits, and the reference was answered in the negative and against the assessee.

Issues: Whether loss arising from speculative business could be set off against profits and gains of other non-speculative business income in computing business profits under the Indian Income-tax Act, 1922.

Analysis: The first proviso to section 24(1) was treated as operating in the same field as section 10 and not as a merely restrictive rider to section 24 alone. The proviso was held to be a substantive provision inserted to prevent speculative losses from reducing taxable income, and therefore speculative loss could be adjusted only against profits from other speculative business. The legislative purpose, scheme of the Act, and the mischief sought to be remedied supported this construction.

Conclusion: The loss from speculative business could not be set off against non-speculative business income; the answer to the reference was in the negative and against the assessee.

Final Conclusion: The reference was answered by holding that speculative losses were confined to set-off against speculative profits and could not be used to reduce other business profits.

Ratio Decidendi: A proviso may operate as a substantive enactment where the statutory scheme and legislative purpose require that result, and a speculative business loss is confined to set-off against speculative business profits only.
