“Now, we come to whether the commission received could form part of export profits. Here again, we are unable to see it differently. It is no doubt true that this commission is not turnover but it is a profit relatable to exports. Coming back to section 80HHC(1), if the assessee is an exclusive exporter without having any local sales, then the profit on commission is admittedly includible as profit of the business computed under the head „Profits and gains of business or profession‟ and the whole of it would be eligible for exemption under clause (a) of sub-section (3) of section 80HHC. When such commission could be regarded as profit derived from export for the purpose of clause (a), how can the same be excluded for the purpose of clause (b) unless it amounted to discrimination. The interpretation of clauses (a) and (b) must be harmonious and not discriminatory, cutting against each other. What is sauce for the goose is also sauce for the gander. Secondly, we have just mentioned that this profit is profit derived from export and export is the basis or the foundation or the nexus. The argument of Shri B. B. Ahuja and all his effort to show to us that it has no reference to the export is, therefore, unacceptable to us. In our opinion, the argument advanced by Shri Ahuja overlooks the fact that the commission would not have come to the assessee had he not been engaged in the export business. He sought to justify his argument by referring to subsequent amendments made from April 1, 1992, whereunder as we have pointed out above by adding clause (baa) to the Explanation at the end of sub-section (4A) with effect from April 1, 1992, 90 per cent. of this commission, etc., is not to be regarded as profits derived from export business and this amendment as explained in the Memorandum of Bill was only to clarify the position.”
