HELD : The observations in Kantilal Nathu Chand's case, cannot be regarded as obiter, because the question of the applicability of the proviso E directly arose in the case. The p'roviso says in unequivocal terms that any losses sustained in speculative transactions which are in the nature of a business shall not be taken into account except to the extent of the amount of profits or gains in any other business consisting of speculative transactions. If this is read with Explanation I, according to which where the speculative transactions carried on are of such a- nature as to constitute a business the business shall be deemed to be distinct and separate from any other business, no other view is possible.
