Clarificatory exemption amendment for miconazole nitrate applied from the original notification date in pharmaceutical use

Miconazole nitrate used in medicinal preparations was treated as covered by the original exemption notification because the evidence showed that the base form of miconazole was not used in India and only the salt form was employed in pharmaceutical formulations. The later notification substituting miconazole nitrate was regarded as clarificatory rather than creating a new exemption, so it operated from the inception of the earlier notification. The commentary notes that even though exemption notifications are strictly construed, the interpretation should not defeat the intended benefit where the notified ingredient is used only in its salt form.

Issues: Whether miconazole nitrate used in the medicinal preparations was covered by Notification No. 122/86 dated 1-3-1986, and whether Notification No. 455/86 dated 21-11-1986 substituting miconazole nitrate was clarificatory so as to apply from the inception of the earlier notification.

Analysis: The evidence showed that miconazole in its base form was not used in pharmaceutical preparations in India and that the salt form was the form actually employed. The subsequent amending notification substituted miconazole nitrate, and the Ministry's clarification stated that the necessary changes were made because only salt forms could be used for the relevant formulations. On that basis, the later notification was treated as explanatory of what was intended from the beginning rather than as creating a new exemption. Although exemption notifications are strictly construed, the construction adopted could not render the exemption nugatory where the notified ingredient was used only in its salt form.

Conclusion: The amendment was held to be clarificatory, and the appellants were entitled to exemption for the product from the inception of Notification No. 122/86.

Final Conclusion: The exemption benefit was held to be available from the original date of the notification, and the appeal succeeded.

Ratio Decidendi: Where the notified therapeutic ingredient is used in trade and manufacture only in its salt form, a subsequent amendment substituting that salt form may be treated as clarificatory and applied from the inception of the original exemption notification.
