SSI exemption and extended limitation under excise law hinge on aggregation rules and proof of wilful suppression.

Under Notification No. 16/97-C.E., the commentary states that SSI exemption required aggregation of clearances from one or more factories for slab-wise treatment, but did not require disclosure of every other unit owned by the manufacturer during the relevant period. It further notes that, absent proof of wilful suppression of material facts with intent to evade duty, the extended limitation under Section 11A could not be invoked. On that basis, the text records that no short levy was shown, the longer period was unavailable, and the demand, interest, and penalty could not be sustained.

Issues: (i) Whether the assessee was required under Notification No. 16/97-C.E. to disclose the existence and duty option of another unit for availing SSI exemption, and whether the exemption had to be applied separately to each factory; (ii) Whether the extended period under Section 11A of the Central Excise Act, 1944 could be invoked on the ground of suppression of facts with intent to evade duty.

Issue (i): Whether the assessee was required under Notification No. 16/97-C.E. to disclose the existence and duty option of another unit for availing SSI exemption, and whether the exemption had to be applied separately to each factory.

Analysis: The notification permitted a manufacturer to either avail the exemption or pay duty at tariff rate, and para 2(v) required aggregation of clearances from one or more factories for slab-wise exemption. It did not impose an obligation, during the relevant period, to disclose every other unit owned by the manufacturer or to treat the election made for one unit as automatically governing another unit. On the facts, the clearances from the assessee's units, when aggregated, did not result in short payment of duty under the notification.

Conclusion: The assessee was entitled to the SSI exemption as applied by the Commissioner, and no short levy was established on this issue.

Issue (ii): Whether the extended period under Section 11A of the Central Excise Act, 1944 could be invoked on the ground of suppression of facts with intent to evade duty.

Analysis: The finding of the lower appellate authority was that the assessee had not wilfully suppressed material facts, and the Revenue produced no evidence to rebut that finding. In the absence of proof of deliberate suppression or intent to evade duty, the conditions for invoking the larger period were not satisfied.

Conclusion: The extended period of limitation was not available to the Revenue.

Final Conclusion: The demand, interest, and penalty could not be sustained, and the Revenue's appeal failed.

Ratio Decidendi: Where an SSI notification requires aggregation of clearances from multiple factories but does not require disclosure of every unit for the relevant period, and where suppression with intent to evade duty is not proved, the extended limitation under Section 11A cannot be invoked and no differential duty demand can survive.
