Trade meaning under the Drugs and Cosmetics Act governed exemption, with refund allowed and immediate interest denied.

Products manufactured under a licence governed by the Drugs and Cosmetics Act, 1940 were treated as drugs and medicines for exemption purposes because the trade meaning, in that statutory setting, aligned with Section 3(b). The Court also stated that tax collected without authority of law was refundable, and on the then prevailing view the doctrine of unjust enrichment did not defeat the refund claim; the claim was not rejected as time-barred merely because tax had continued to be paid until exemption was asserted. Immediate interest on the refund was declined, with interest to arise only if repayment was not made within the stipulated period.

Issues: (i) Whether the products manufactured by the petitioners were "drugs and medicines" covered by the exemption notifications, and (ii) whether the petitioners were entitled to refund of the excess tax paid, including the effect of unjust enrichment and limitation, and (iii) whether interest could be granted on the refund.

Issue (i): Whether the products manufactured by the petitioners were "drugs and medicines" covered by the exemption notifications.

Analysis: The relevant test for a taxing entry is ordinarily the commercial or popular meaning, but in the setting of the Drugs and Cosmetics Act, 1940, the statutory control over manufacture, sale and distribution of drugs makes the definition in that Act highly relevant. The Court held that the trade meaning of the petitioners' products, being manufactured under a licence under that Act and regulated by its prohibitory and penal provisions, is synonymous with the meaning given in Section 3(b). Earlier decisions relied on by the Revenue were distinguished because they dealt with different questions and different tariff entries.

Conclusion: The products were held to be drugs and medicines and, therefore, eligible for exemption.

Issue (ii): Whether the petitioners were entitled to refund of the excess tax paid, including the effect of unjust enrichment and limitation.

Analysis: The Court followed its earlier line of authority that tax collected without authority of law can be refunded and that the doctrine of unjust enrichment did not defeat such a claim in the then prevailing legal position. The Revenue's reliance on a contrary view was rejected. On delay, the Court accepted that the petitioners' claim was not barred merely because they had continued to pay tax until the exemption was realised and raised the refund claim thereafter.

Conclusion: The petitioners were held entitled to refund of the excess tax paid.

Issue (iii): Whether interest could be granted on the refunded amount.

Analysis: Although refund was allowed, the Court declined the claimed rate of interest for the past period and directed refund within a specified time without interest, with interest to run only if the refund was not made within that period.

Conclusion: The claim for immediate interest was rejected, subject to future interest if refund was delayed beyond the stipulated time.

Final Conclusion: The assessment orders were not sustained to the extent they imposed tax on the petitioners' products beyond the exempted rate, and the petitioners were granted refund of excess tax, but their claim for immediate interest was curtailed.

Ratio Decidendi: Where a fiscal exemption turns on the character of goods, the meaning borne by the relevant trade regulated by a special statute may control, and tax collected without authority of law remains refundable notwithstanding a rejected plea of unjust enrichment on the facts then prevailing.
