Provisional excise assessment left pending and belatedly finalised cannot sustain differential duty demand after missed remand timelines.

Provisional excise assessment left pending for an inordinate and unexplained period cannot support a demand for differential duty where finalisation and recovery are not completed in time. The text notes that Rule 9B required final assessment before adjustment, and that the belated notice and prolonged inaction were fatal to the demand. It also states that non-compliance with an earlier Tribunal remand directing completion of de novo proceedings and finalisation within four months rendered the subsequent proceedings invalid. The impugned order was therefore set aside.

Issues: (i) Whether the demand and confirmation of differential duty were unsustainable because the provisional assessment was not finalized and no effective notice for recovery was issued within a reasonable time; (ii) Whether non-compliance with the earlier Tribunal direction to complete the de novo proceedings and finalize the assessment within four months vitiated the impugned proceedings.

Issue (i): Whether the demand and confirmation of differential duty were unsustainable because the provisional assessment was not finalized and no effective notice for recovery was issued within a reasonable time.

Analysis: The assessment arose from a classification dispute and remained provisional. The order of 14.10.1986 itself contemplated finalization of provisional assessment and consequential demand under Section 11A. The record showed no timely finalization and no prompt demand notice for many years. Rule 9B of the Central Excise Rules, 1944 required final assessment before adjustment and recovery of differential duty. The prolonged inaction, without any plausible explanation, was held to be fatal to the demand.

Conclusion: The demand based on belated finalization of provisional assessment was unsustainable and could not be sustained against the assessee.

Issue (ii): Whether non-compliance with the earlier Tribunal direction to complete the de novo proceedings and finalize the assessment within four months vitiated the impugned proceedings.

Analysis: The earlier remand required the Original Authority to finalize the provisional assessment within four months after due notice. The subsequent proceedings took about fourteen months, and no request for extension or modification of the time limit was moved. The Tribunal treated the earlier direction as mandatory in the circumstances and held that the Revenue could not rely on the belated de novo exercise after having already failed to act within the fixed time frame.

Conclusion: The failure to comply with the Tribunal's time-bound remand rendered the impugned proceedings invalid and was held against the Revenue.

Final Conclusion: The appeal succeeded because the differential duty proceedings were vitiated by inordinate delay and non-compliance with the binding time limit for finalizing provisional assessment; the impugned order was set aside.

Ratio Decidendi: Where provisional assessment is kept pending for an inordinate and unexplained period and the authority fails to complete finalization within the time fixed by a binding remand order, the consequential demand for differential duty is not sustainable.
