Notification-based exclusion barred narcotic-drug classification for medicinal formulations within the specified Dextropropoxyphene threshold.

Medicinal preparations for oral use containing not more than the notified quantity of Dextropropoxyphene were treated as excluded by the relevant notification, so they could not be classified as narcotic drugs for levy purposes under the Medicinal and Toilet Preparations (Excise Duties) Act, 1955. On a plain reading of the notification, preparations containing 65 mg of Dextropropoxyphene fell within the exclusion, making the contrary classification and excise demand inconsistent with the statutory scheme. The analysis therefore confirms that products within the specified threshold are outside the Act's narcotic-drug levy.

Issues: Whether medicinal formulations containing less than 135 mg of Dextropropoxyphene could be classified as a narcotic drug under Section 2(h) of the Medicinal and Toilet Preparations (Excise Duties) Act, 1955, and subjected to duty under that Act.

Analysis: The relevant notification excluded preparations for oral use containing not more than 135 milligrams of Dextropropoxyphene base per dosage unit. The formulations in question contained only 65 mg of Dextropropoxyphene. On a plain reading of the notification, such preparations fell within the exclusion and could not be treated as narcotic drugs or narcotics for the purpose of the Act. The contrary view adopted in the impugned orders was inconsistent with the applicable notification and the earlier decisions relied upon.

Conclusion: The formulations containing less than 135 mg of Dextropropoxyphene were not classifiable as narcotic drugs under the Act and the demand of excise duty could not stand.

Final Conclusion: The petition succeeded, the impugned orders were set aside, and the petitioners were granted consequential relief.

Ratio Decidendi: Where a statutory notification expressly excludes medicinal preparations containing not more than the stipulated quantity of a specified substance, preparations falling within that threshold cannot be treated as narcotic drugs for levy purposes under the Act.
