Final assessment is required before Section 11A recovery for short-levied excise duty can validly begin.

A show cause notice under Section 11A of the Central Excise and Salt Act, 1944 could not be issued before assessment was finally completed, because the provision operated only after short-levy or short-payment was crystallised by final assessment. The order dated 10.04.1986 was not a final assessment order since it only set out valuation principles, while the later order dated 28.04.1988 finalised the provisional assessments and determined the differential duty. Rule 9B(5) of the Central Excise Rules, 1984 reinforced that provisional assessments acquire finality only on adjustment against the duty finally assessed. The ratio of Serai Kella Glass Works Pvt. Ltd. therefore supported the assessee.

Issues: (i) Whether a show cause notice under Section 11A of the Central Excise and Salt Act, 1944 could be issued before completion of assessment proceedings and whether the order dated 10.04.1986 was a final assessment order; (ii) Whether the ratio of Serai Kella Glass Works Pvt. Ltd. applied to the facts of the case.

Issue (i): Whether a show cause notice under Section 11A of the Central Excise and Salt Act, 1944 could be issued before completion of assessment proceedings and whether the order dated 10.04.1986 was a final assessment order.

Analysis: The applicable framework required assessment to be completed before the machinery under Section 11A could be invoked, because the provision operated on short-levy or short-payment determined after final assessment. The order dated 10.04.1986 only laid down the principles for valuation and did not finally determine the duty payable for the relevant factory. The later order dated 28.04.1988 alone finalized the provisional assessments and crystallized the differential duty. Rule 9B(5) of the Central Excise Rules, 1984 showed that provisional assessment was adjusted only against the duty finally assessed, reinforcing that finality arises only on such adjustment.

Conclusion: The show cause notice could not validly be issued before completion of assessment, and the order dated 10.04.1986 was not a final assessment order; this issue was decided in favour of the assessee.

Issue (ii): Whether the ratio of Serai Kella Glass Works Pvt. Ltd. applied to the facts of the case.

Analysis: The later Supreme Court decision in ITC Ltd. had already noted Serai Kella and treated its principle as consistent with the view that Section 11A becomes operative only after final assessment. Since the assessment here remained provisional when the impugned notice was issued, the reasoning of Serai Kella supported the assessee's challenge.

Conclusion: The ratio of Serai Kella Glass Works Pvt. Ltd. applied to the facts and supported the assessee's case.

Final Conclusion: The impugned notice and consequential communication were unsustainable because the demand machinery was invoked before the assessments had been finally completed.

Ratio Decidendi: A notice for recovery of short-levied central excise duty under Section 11A cannot be issued until the assessment is finally completed, and provisional assessment is not finality for that purpose.
