Base clearances under Notification 198/76 must use section 4 values, while unsupported extended limitation fails on approved disclosures.

Under Notification No. 198/76, base clearances were to be computed on actual section 4 values for the base period, not on the adjusted figures used only to identify the base period, because a harmonious reading of the notification required comparable values and did not permit carried-forward adjustments. On limitation, show-cause notices issued on a footing of wilful suppression were treated as time-barred where the assessees had filed supplementary classification lists and the Department had approved them, with no legally sufficient basis for extended limitation on the record.

Issues: (i) Whether, under Notification No. 198/76, the base clearances were to be computed on the basis of the adjusted values used for fixing the base period or on the basis of values determined under section 4 of the Central Excises and Salt Act, 1944. (ii) Whether the show-cause notices were barred by limitation under Rule 10(1) of the Central Excises Rules, 1944.

Issue (i): Whether, under Notification No. 198/76, the base clearances were to be computed on the basis of the adjusted values used for fixing the base period or on the basis of values determined under section 4 of the Central Excises and Salt Act, 1944.

Analysis: The notification treated adjustment with reference to the wholesale price index as relevant for determining the base period, while Explanation 1(b) and Explanation 2 governed computation of excess clearances in the incentive year by reference to the value prevailing in the base period under section 4. A harmonious reading showed that the adjusted figures used to select the base period could not be carried forward to determine base clearances, because that would compare non-comparable figures and defeat the structure of the notification. Base clearances therefore had to be taken on the unadjusted section 4 values of clearances during the base period.

Conclusion: The base clearances were to be computed on the basis of values determined under section 4 of the Central Excises and Salt Act, 1944, and not on the adjusted values used for fixing the base period.

Issue (ii): Whether the show-cause notices were barred by limitation under Rule 10(1) of the Central Excises Rules, 1944.

Analysis: The notices proceeded on the footing of wilful suppression, but the record showed that the assessees had filed supplementary classification lists and the Department had approved them. The assessee had not, on these facts, been shown to have secretly availed the benefit on its own so as to justify a contrary limitation finding. In these circumstances, the Appellate Collector's view that the notices were time-barred could not be said to be erroneous.

Conclusion: The notices were held to be barred by limitation.

Final Conclusion: The interpretative issue on Notification No. 198/76 was decided against the Revenue, but the dismissal ultimately rested on limitation, so the assessees succeeded and the departmental demand did not survive.

Ratio Decidendi: Where a notification uses adjusted values only to determine the base period, the base clearances must be computed on the actual section 4 values for that base period unless the notification expressly provides otherwise; and a demand issued beyond the normal period cannot be sustained absent a legally supportable basis for extended limitation.
