Excise valuation and retrospective amendment: only duty actually payable can be excluded, and trade notice cannot alter exemption terms

Parliament was held competent under Article 246 read with Entry 84 of List I to insert the Explanation in section 4(4)(d)(ii) of the Central Excises and Salt Act, 1944, and the amendment could operate retrospectively from 1-10-1975 as a valid clarificatory and validating provision. For excise valuation under section 4, only the duty actually payable after giving effect to an exemption notification may be excluded from assessable value. A Collector cannot expand or modify the notification by trade notice, so the notice and assessment orders founded on it were quashed and the matter was remitted for redetermination according to law.

Issues: (i) Whether the Explanation inserted by section 47 of the Finance Act, 1982 into section 4(4)(d)(ii) of the Central Excises and Salt Act, 1944 was within parliamentary competence and could operate retrospectively from 1-10-1975; and (ii) whether, in computing assessable value under section 4, only the duty actually payable after giving effect to the exemption notification could be excluded, and whether the Collector's trade notice and the consequential assessment orders were valid.

Issue (i): Whether the Explanation inserted by section 47 of the Finance Act, 1982 into section 4(4)(d)(ii) of the Central Excises and Salt Act, 1944 was within parliamentary competence and could operate retrospectively from 1-10-1975

Analysis: Parliament had competence under Article 246 read with Entry 84 of List I to legislate on excise duty and matters incidental to it. The power to enact tax legislation also includes power to give it retrospective effect. The Explanation was expressly made retrospective and was treated as a valid clarificatory and validating provision.

Conclusion: The challenge to the constitutional validity and retrospectivity of the Explanation failed and the provision was upheld.

Issue (ii): Whether, in computing assessable value under section 4, only the duty actually payable after giving effect to the exemption notification could be excluded, and whether the Collector's trade notice and the consequential assessment orders were valid

Analysis: Section 4 fixes the assessable value on the real duty payable by the assessee, and where a notification grants exemption or reduction, the effective duty actually payable alone is to be taken into account. The Collector had no power to add to or modify the exemption notification by trade notice, and the notice improperly sought to regulate assessments by imposing a condition not found in the notification. The impugned assessment and refund orders, being founded on that notice and contrary to the correct construction of section 4 as amended, could not stand.

Conclusion: The trade notice and the impugned orders were quashed, and the authorities were directed to redetermine the matters in accordance with law and the Court's interpretation of section 4.

Final Conclusion: The statutory amendment was sustained, but the departmental trade notice and the consequential assessments based on it were set aside, with the matters sent back for fresh determination on the correct legal basis.

Ratio Decidendi: For excise valuation, where an exemption notification reduces the duty payable, only the effective duty actually payable by the assessee can be excluded from the assessable value, and an administrative authority cannot alter the exemption scheme by trade notice.
