Limitation for excise demand notices: later clarificatory circulars do not bar timely notices, and retrospective amendment supports recovery.

The SC held that show cause notices issued within six months of the relevant periods were not time-barred. A later circular did not invalidate the demand because it was merely clarificatory and did not govern the legality of the notices. The Court also relied on the retrospective amendment to Section 11A of the Central Excise Act, 1944, which permits recovery where duty has not been levied, short-levied, short-paid, or erroneously refunded, even if the non-levy or short levy arose from prior approval, acceptance, or assessment. The limitation objection was rejected and the demand was upheld as within time.

Issues: Whether the demand raised through the show cause notices was barred by limitation.

Analysis: The show cause notices were issued within six months of the relevant periods. The Tribunal had treated the demand as time-barred on the footing that it followed a later circular and that the revised classification could operate only prospectively. The Court held that the circular was merely clarificatory and did not control the validity of the demand notices. It further relied on the amended Section 11A of the Central Excise Act, 1944, which permits issue of a notice where duty has not been levied, short-levied, short-paid, or erroneously refunded, whether or not the non-levy or short levy was based on approval, acceptance, or assessment, and noted that the amendment operated retrospectively.

Conclusion: The demand was not time-barred and the objection on limitation failed.

Final Conclusion: The limitation challenge was rejected and the matter stood disposed of on that basis.

Ratio Decidendi: A demand notice issued within the statutory period is not rendered time-barred merely because it precedes a later clarificatory circular or modification order, and retrospective amendment to Section 11A authorises recovery notwithstanding prior approval or assessment.
