Excise exemption under old notification survives successor rules where transitional provisions preserve it and conditions remain satisfied.

A notification granting excise exemption for raw naphtha used to flush pipelines continued to apply after repeal of the 1944 Rules because the successor transitional provisions preserved earlier notifications where they remained relevant and consistent with the new regime. The court also relied on the later rules' treatment of goods brought back to the factory as supporting the same relief. As the notification's conditions were satisfied, the assessee remained entitled to the exemption and no excise duty was payable on the naphtha used for pipeline flushing and returned for further processing.

Issues: Whether the assessee was entitled to the benefit of Notification No. 218/1984 dated 1-12-1984, issued under Section 143-A of the Central Excise Rules, 1944, after repeal of the old rules and in the absence of a specific corresponding provision in the new rules.

Analysis: The notification exempted raw naphtha used for flushing pipelines from excise duty, subject to the condition that the flushed oil was received back in the crude tank for further processing. The Court held that the repeal of the 1944 Rules and the introduction of the 2001 and 2002 Rules did not alter the legal position, because the transitional provisions in Rule 32 of the Central Excise (No. 2) Rules, 2001 and Rule 33 of the Central Excise (No. 2) Rules, 2002 deemed earlier notifications to remain valid to the extent they were relevant and consistent with the new rules. Rule 16 of the 2002 Rules also supported the same result by recognising credit or refund treatment where duty had been paid on goods brought back to the factory. Since the notification was consistent with the new regime, the assessee remained entitled to its benefit.

Conclusion: The assessee was entitled to the benefit of Notification No. 218/1984, and no excise duty was payable on the naphtha used for pipeline flushing and returned to the refinery for further processing.

Ratio Decidendi: A notification issued under the old excise rules continues to operate under the successor rules if the transitional provision deems it valid and it is relevant and consistent with the new statutory framework.
