Retrospective excise valuation amendment requires deduction of effective duty after exemption notification is applied.

A retrospective amendment by the Finance Act, 1982 altered the excise valuation scheme so that the duty deductible from the cum-duty price under Section 4(4)(d)(ii) had to be the effective duty actually payable after full effect was given to the Rule 8 exemption notification. The earlier two-stage approach, under which assessable value was first determined on the tariff rate and the exemption applied later, was displaced because the validating amendment integrated the exemption into the computation itself. As a result, the assessable value had to be worked out on the basis of the effective duty after taking the notification into account, and prior contrary decisions under the earlier statutory scheme no longer governed.

Issues: Whether, after the retrospective amendment made by the Finance Act, 1982, the assessable value of cigarettes under Section 4(4)(d)(ii) of the Central Excises and Salt Act, 1944 had to be computed by deducting only the effective duty payable after giving effect to the Rule 8 exemption notification, thereby displacing the earlier view that the exemption was to be applied after determining assessable value on the tariff rate.

Analysis: The earlier line of decisions had treated the charging provision and the exemption notification as operating in two separate stages, so that assessable value was first determined with reference to the tariff rate and only thereafter the exemption was applied. The retrospective Explanation inserted by Section 47 of the Finance Act, 1982 altered Section 4(4)(d)(ii) by defining the duty deductible from the cum-duty price as the total of the effective duties payable, and by requiring the effective duty under each Act to be computed after giving full and complete effect to the exemption notification. The amendment, coupled with its validating and retrospective operation, was held to have removed the basis of the earlier judgments and to have integrated the notification into the computation of assessable value itself.

Conclusion: The assessable value had to be worked out on the basis of the effective duty payable after taking the exemption notification into account, and the earlier contrary approach was no longer applicable. This issue was decided against the assessee and in favour of the Revenue.

Ratio Decidendi: Where a retrospective validating amendment expressly requires deduction of only the effective duty payable after giving full and complete effect to an exemption notification, the assessable value must be computed on that basis and prior judgments resting on the earlier statutory scheme stand neutralised.
