Special refund scheme limitation barred recovery of Modvat refund; extended suppression period could not be imported by implication.

Recovery of Modvat refund under Rule 57F(3) and Notification No. 85/87 was treated as governed by a special, self-contained scheme with its own repayment safeguards and limitation. Because the notification required repayment of erroneous refund within six months and did not incorporate Section 11A, the general extended period for suppression could not be read into the scheme by implication. The show cause notice issued in 1993 for refunds relating to 1990-1991 was therefore held time-barred, and the impugned demand was set aside.

Issues: Whether recovery of refund of Modvat credit sanctioned under Rule 57F(3) and Notification No. 85/87 was barred by limitation, and whether the extended period under Section 11A could be invoked on allegations of suppression.

Analysis: The refund mechanism under Rule 57F(3) and the notification was treated as a special, self-contained scheme with its own safeguards and a built-in limitation. Clause 4 required erroneous refund to be repaid on demand within six months, and Clause 7 required filing before the expiry of the period specified in Section 11B, but the notification made no reference to Section 11A. The provision governing recovery under the notification was therefore construed independently, and the Tribunal declined to import the extended period under Section 11A or its proviso into a scheme where the statute and notification had already fixed the relevant time limit. On that construction, the show cause notice issued on 19-1-1993 for refunds relating to April 1990 to December 1991 was beyond time.

Conclusion: The recovery proceedings were barred by limitation, and the extended period under Section 11A could not be applied to the refund claim under Rule 57F(3) and Notification No. 85/87.

Final Conclusion: The impugned demand was set aside and the appeal was allowed because the notice for recovery of the refund was time-barred under the special refund notification.

Ratio Decidendi: Where a statutory refund notification creates a special scheme with an express repayment period and no incorporation of the general recovery provision, the general extended limitation for suppression cannot be read into it by implication.
