Post-manufacturing freight excluded from excise value, with refund and interest allowed on duty collected on transport charges.

Freight and transport charges incurred for moving goods from the factory to wholesale dealers' premises were treated as post-manufacturing expenses excluded from assessable value under Section 4 of the Central Excises and Salt Act, 1944, so duty collected on that component was refundable. The suit for refund was held within limitation because the claim related to payments made within three years of filing and the earlier discovery-of-mistake objection was immaterial on the facts. Following earlier precedents, the Court also approved interest on the wrongfully collected duty at 12% per annum from the date of collection until payment, with costs and quantum to be worked out by the Assistant Collector.

Issues: (i) Whether the suit for refund of excise duty paid on transport charges was within limitation and not defeated by the plea that the relevant mistake was discovered earlier; (ii) Whether freight and transport charges from the factory to the wholesale dealers' premises formed part of the assessable value for excise duty under the Central excise law; (iii) Whether the plaintiffs were entitled to interest on the refunded duty.

Issue (i): Whether the suit for refund of excise duty paid on transport charges was within limitation and not defeated by the plea that the relevant mistake was discovered earlier.

Analysis: The claim was confined to payments made within three years before the suit, with an additional period covered by the statutory notice under Section 80 of the Code of Civil Procedure, 1908. The claim was therefore within the three-year period prescribed by Article 115 of the Limitation Act, 1963. The contention that the suit was barred by an earlier date of discovery of mistake was treated as immaterial on the facts, since the claim did not relate to any period before the Supreme Court's decision in Voltas.

Conclusion: The suit was within limitation and the plea of earlier discovery did not defeat the claim.

Issue (ii): Whether freight and transport charges from the factory to the wholesale dealers' premises formed part of the assessable value for excise duty under the Central excise law.

Analysis: Under Section 4 of the Central Excises and Salt Act, 1944, the assessable value excludes post-manufacturing expenses. Freight and transport charges incurred for carrying goods from the factory to the wholesale dealers' premises are post-manufacturing expenses and are deductible. Where average freight had been built into the wholesale cash price, only the freight component actually included in the price could be excluded for quantification of refund. A levy collected without authority of law cannot be retained on a plea of voluntariness or estoppel.

Conclusion: Freight and transport charges were not includible in the assessable value, and the duty collected on that component was refundable.

Issue (iii): Whether the plaintiffs were entitled to interest on the refunded duty.

Analysis: The Court followed earlier precedents awarding interest on amounts wrongfully collected as excise duty and considered 12% per annum to be fair in the circumstances.

Conclusion: Interest at 12% per annum was awarded from the date of collection till payment.

Final Conclusion: The plaintiffs succeeded in obtaining refund of excise duty collected on transport charges, together with interest and costs, and the exact quantum was directed to be determined by the Assistant Collector.

Ratio Decidendi: In computing excise duty under Section 4 of the Central Excises and Salt Act, 1944, post-manufacturing freight and transport charges up to the wholesale dealer's premises are excluded from assessable value, and duty collected on such excluded charges is refundable with interest.
