Chapter VI-A overlap limits double deduction; duty drawback, DEPB and foreign tour expense disallowance were ruled on evidentiary nexus.

Section 80-IA(9), as applied through section 80-IB(13), requires deduction under section 80HHC to be computed after reducing the deduction already allowed under section 80-IB, so the overlap cannot be claimed twice. Duty drawback and DEPB receipts were treated as eligible for deduction under section 80-IB because they were held to have a direct nexus with the eligible industrial undertaking's business profits. An ad hoc disallowance of foreign tour expenses was deleted because no specific item of personal or unsupported expenditure was identified, and conjectural disallowance is impermissible.

Issues: (i) Whether deduction under section 80HHC was to be computed after reducing the deduction allowed under section 80-IB by virtue of section 80-IA(9) as applied through section 80-IB(13); (ii) Whether duty drawback and DEPB receipts were eligible for deduction under section 80-IB; (iii) Whether ad hoc disallowance of foreign tour expenses was sustainable.

Issue (i): Whether deduction under section 80HHC was to be computed after reducing the deduction allowed under section 80-IB by virtue of section 80-IA(9) as applied through section 80-IB(13).

Analysis: Section 80-IA(9) prohibits allowance of deduction to the extent of profits already allowed under that section under other provisions of Chapter VI-A under the heading relating to deductions in respect of certain incomes. Section 80-IB(13) makes those restrictions applicable to section 80-IB. The Tribunal also treated the Special Bench decision in Rogini Garments as binding and held that the later High Court decision relied on by the assessee did not consider the effect of section 80-IA(9A).

Conclusion: The deduction under section 80HHC had to be computed after reducing the deduction allowed under section 80-IB. This issue was decided against the assessee.

Issue (ii): Whether duty drawback and DEPB receipts were eligible for deduction under section 80-IB.

Analysis: The relevant language of section 80-IB requires profits and gains derived from the business of the eligible industrial undertaking. The Tribunal applied the principle of direct nexus and followed the jurisdictional High Court decision holding that duty drawback arises from the business of the industrial undertaking. It also accepted the view that DEPB receipts, on the facts of the case, formed part of the eligible business profits.

Conclusion: Duty drawback and DEPB receipts were held eligible for deduction under section 80-IB. This issue was decided in favour of the assessee.

Issue (iii): Whether ad hoc disallowance of foreign tour expenses was sustainable.

Analysis: The disallowance was made on an estimated basis without identifying any specific item of personal expenditure. In the absence of supporting material, the estimated disallowance could not be sustained, and the Tribunal followed the principle that conjectural disallowance is impermissible.

Conclusion: The ad hoc disallowance of foreign tour expenses was deleted. This issue was decided in favour of the assessee.

Final Conclusion: The appeal succeeded only in part, with relief granted on the eligibility of duty drawback and DEPB receipts and on foreign tour expenses, while the computation of deduction under section 80HHC remained restricted by the deduction allowed under section 80-IB.

Ratio Decidendi: Where a specific restriction in Chapter VI-A applies through a deeming or application provision, the deduction under one provision must be reduced before computing another overlapping deduction, and eligible business profits may include receipts having a direct nexus with the industrial undertaking, while ad hoc disallowances require evidentiary support.
