Cum-duty valuation turns on effective excise duty after exemption, with refund not justifying recomputation of assessable value.

In computing assessable value from a cum-duty price, the deductible excise duty is the effective duty legally payable under the applicable exemption regime, not the statutory rate divorced from the exemption. For the period on or after 1-10-1975, the retrospective Explanation inserted by the Finance Act, 1982 required the duty deduction to be calculated after full effect was given to the exemption notification, and the point was resolved against the assessee. For the earlier period, the majority held that the assessable value could not be recomputed by adding back the refunded amount, because the notification still required deduction of the effective duty actually payable; the appeals were rejected, although one member dissented on that issue.

Issues: (i) Whether, for the period on or after 1-10-1975, the duty deductible from the cum-duty price had to be computed on the basis of the effective duty after giving full effect to the exemption notification. (ii) Whether, for the period prior to 1-10-1975, the assessable value could be recomputed by adding back the amount refunded under the exemption notification, so as to deny the assessee the benefit of deduction of the unadjusted duty.

Issue (i): Whether, for the period on or after 1-10-1975, the duty deductible from the cum-duty price had to be computed on the basis of the effective duty after giving full effect to the exemption notification.

Analysis: The retrospective Explanation inserted by Section 47 of the Finance Act, 1982 clarified that where an exemption was in force, the duty of excise payable was to be taken as the duty computed with reference to the statutory rate as reduced to give full and complete effect to the exemption. The expression used in the Explanation was directed to the effective duty payable, and the legislative note made it clear that only the effective amount of duty payable under assessment was to be taken into account in computing the deduction from the cum-duty price.

Conclusion: The issue was decided against the assessee and in favour of the Revenue.

Issue (ii): Whether, for the period prior to 1-10-1975, the assessable value could be recomputed by adding back the amount refunded under the exemption notification, so as to deny the assessee the benefit of deduction of the unadjusted duty.

Analysis: The pre-amendment section was held not to contain the later Explanation, and the retrospective amendment was confined to 1-10-1975 onwards. The majority preferred the Bombay High Court view in the case concerning the same commodity and similar exemption, and held that the relevant notification required deduction of the effective duty actually payable after giving effect to the rebate. It was further held that the notification did not create discrimination, that the possibility of provisional assessment met the objection based on uncertainty, and that the refund could not be treated as an addition to the assessable value.

Conclusion: The issue was decided against the assessee and in favour of the Revenue.

Dissenting Opinion: Shri M. Gouri Shankar Murthy held that for the period prior to 1-10-1975 the assessable value could not be recomputed by adding back the refunded duty, because the unamended Section 4 excluded only the duty payable at removal and did not permit later enhancement of assessable value by reference to a subsequent rebate. On that view, the appeal should have been allowed for the earlier period.

Final Conclusion: By majority, the notifications were construed to require deduction of the effective duty after exemption for both periods, and the appeals were rejected.

Ratio Decidendi: In computing assessable value from a cum-duty price, the deductible duty is the effective duty legally payable under the applicable exemption regime, and a later refund or rebate does not, by itself, justify recomputation of assessable value unless the governing statutory text so provides.
