Concessional excise duty depends on the operative certificate period; later release orders cannot enlarge certified entitlement.

Entitlement to concessional excise duty under the incentive scheme depended on the scope of the operative certificate covering the relevant clearance period. Certificate No. 805 covered only 1985-86 to 1989-90, and the 1992 release orders did not enlarge that certificate or create a fresh entitlement for the disputed period. As Notifications Nos. 130/83 and 131/83 operated only within the certified period, the claimed concessional rate was unavailable. The Revenue's objection was accepted, and the respondents were held not entitled to the concession for the period claimed.

Issues: Whether the respondents were entitled to concessional rate of duty on sugar clearances for the claimed period on the strength of Certificate No. 805 and the subsequent release orders issued in 1992 under the incentive scheme.

Analysis: The Certificate No. 805 issued by the Directorate of Sugar covered only the period 1985-86 to 1989-90. The later release orders issued in 1992 did not expand that certificate so as to cover the disputed period. The entitlement under Notifications Nos. 130/83 and 131/83 depended on the scope of the operative certificate, and the subsequent release orders could not confer a fresh entitlement beyond the period already certified.

Conclusion: The respondents were not entitled to the concessional rate of duty for the period claimed, and the Revenue's objection was accepted.

Ratio Decidendi: Entitlement to concessional excise duty under an incentive scheme must flow from the operative certificate covering the relevant period, and subsequent release orders cannot enlarge that certified entitlement.
