Excess production rebate under excise notification applies slab percentages to actual excess output, not average prior production.

A rebate notification for sugar excise duty issued under the Central Excise Rules was construed as applying slab-wise relief to the actual excess production over the average production of the preceding five sugar years. The dispute concerned whether the percentage slabs in Item 2 were to be worked out against the excess production itself or against the average production. The interpretation adopted was that expressions such as "on excess production up to 7.5%" and "on excess production on the next 10%" refer to percentages of the excess production, not the average production. That construction followed the plain language of the notification and aligned with other High Court interpretations.

Issues: Whether, under the notification dated 12 October 1974 granting rebate of excise duty on sugar, the percentage slabs in Item 2 were to be worked out with reference to the actual excess production over the average production of the preceding five sugar years or with reference to the average production itself.

Analysis: The notification, issued in exercise of the power under Rule 8(1) of the Central Excise Rules, 1944, granted rebate on sugar produced in excess of the average production of the corresponding period of the preceding five sugar years. The dispute turned on the meaning of the slab expressions such as "on excess production up to 7.5%" and "on excess production on the next 10%". The Court accepted the construction that these expressions relate to percentages of the excess production itself, and not to percentages of the average production of the previous five years. That reading was consistent with the plain language of the notification and with the view taken by other High Courts that had interpreted the same notification.

Conclusion: The rebate had to be calculated on the basis of actual excess production, and not with reference to the average production of the corresponding period of the preceding five sugar years.

Ratio Decidendi: Where an exemption or rebate notification grants slab-wise relief on "excess production", the slab percentages are to be applied to the excess production itself unless the notification expressly provides otherwise.
