Strict construction of exemption notifications excludes regulators, while absence of suppression limits the excise demand to the normal period.

Exemption notifications are construed strictly on their express words, so the phrase "Electric Fans all sorts" in Notification No. 198/76 was held to cover fans only and not regulators. The subsequent amendment of the tariff heading to include "electric fans including regulators" did not justify reading regulators into the earlier notification, and an exemption cannot be enlarged by implication. On limitation, the extended period under excise law was unavailable because the demand had been shown in RT 12 returns and there was no adequate proof of wilful suppression or deliberate evasion. The demand was therefore confined to the normal limitation period, with relief granted only in part.

Issues: (i) Whether the words "Electric Fans all sorts" in Notification No. 198/76 covered regulators also; (ii) whether the extended period of limitation under Section 11A of the Central Excises and Salt Act was available.

Issue (i): Whether the words "Electric Fans all sorts" in Notification No. 198/76 covered regulators also.

Analysis: The notification had to be construed on its plain language. The fact that the tariff heading was later amended to include "electric fans including regulators" did not justify reading the word "regulator" into the exemption notification when the notification itself did not say so. An exemption entry may cover only part of a tariff item, and nothing in the notification showed an intention to extend the concession to regulators. Exemption notifications cannot be enlarged by implication.

Conclusion: The notification covered fans only and did not extend to regulators.

Issue (ii): Whether the extended period of limitation under Section 11A of the Central Excises and Salt Act was available.

Analysis: The demand had been reflected in the relevant RT 12 returns and there was no adequate proof of wilful suppression or deliberate evasion. The record did not show removal of goods without proper entries, and the facts disclosed pointed more to a mistaken view of duty liability than to conduct justifying the longer limitation period.

Conclusion: The extended period was not available and the demand was confined to the normal period of limitation.

Final Conclusion: The exemption was denied to regulators, but the duty demand was restricted to the normal limitation period, so the Revenue succeeded only in part.

Ratio Decidendi: An exemption notification must be interpreted strictly on its express words, and a larger period of limitation under the excise law cannot be invoked without proof of suppression or wilful evasion.
