Extended limitation and DTA entitlement: prior investigation barred suppression-based notice, and exempt cotton waste was excluded from computation.

A later show-cause notice could not validly invoke the extended period of limitation on suppression where the same under-valuation had already been investigated by the department and settled earlier; the duty demand was therefore confined to the normal limitation period. For computation of DTA entitlement under the relevant exemption notification and policy regime, the value of unconditionally exempt cotton waste was not required to be included, as the applicable policy treatment differed from the earlier precedent relied on by Revenue. Revenue's challenge on that issue failed, and the matter was remanded only for re-quantification within the normal period.

Issues: (i) Whether the second show-cause notice could sustain invocation of the extended period of limitation on the allegation of suppression when the underlying under-valuation had already been investigated and settled earlier; (ii) Whether the value of cotton waste was required to be included while computing the DTA entitlement and the corresponding duty benefit under the exemption notification.

Issue (i): Whether the second show-cause notice could sustain invocation of the extended period of limitation on the allegation of suppression when the underlying under-valuation had already been investigated and settled earlier.

Analysis: The disputed under-valuation had already been investigated by the Revenue and formed the basis of an earlier notice that culminated in settlement before the Settlement Commission. On the same known facts, the later notice sought to recompute the DTA ceiling and again invoked suppression. Since the relevant facts were already within the knowledge of the department, the later notice could not validly rest the extended period on a fresh allegation of suppression.

Conclusion: The invocation of the extended period was not sustainable and the duty demand was confined to the normal period of limitation.

Issue (ii): Whether the value of cotton waste was required to be included while computing the DTA entitlement and the corresponding duty benefit under the exemption notification.

Analysis: The benefit under the relevant notification was linked to DTA clearances in accordance with the Exim Policy and the ceiling of 50% of FOB exports. For the period in question, the applicable policy position and the later Tribunal view treated unconditionally exempt cotton waste as not required to be counted towards the DTA sales entitlement. The contrary precedent relied upon by Revenue related to an earlier policy regime and was held inapplicable.

Conclusion: The value of cotton waste was not required to be included in the DTA entitlement computation, and Revenue's appeal on this aspect failed.

Final Conclusion: The Revenue's appeal was rejected, while the assessee's appeals succeeded in part, the matter being sent back for re-quantification of duty within the normal limitation period.

Ratio Decidendi: Where the department is already aware of the material facts and has earlier investigated the same suppression-based allegation, a later notice cannot validly invoke the extended period on the same facts; and for the relevant policy regime, unconditionally exempt cotton waste is not to be counted towards DTA entitlement.
