Excess production rebate must be slab-wise on excess output, with later legal interpretation applied at the appellate stage.

Rebate on sugar produced in excess had to be computed by first dividing the excess production into the relevant slabs and then apportioning each slab between levy sugar and free sale sugar in the prescribed 65:35 ratio. A method that first segregated levy and free sale sugar and then applied the slab rates on a combined base was incorrect because it distorted the percentage-wise working under the notification. The text also notes that a later judicial interpretation clarifying that the slabs must be measured by reference to excess production, not average production, could be applied at the appellate stage where the refund claim rested on the same factual foundation and only the legal basis for quantification had changed.

Issues: (i) whether the rebate on sugar produced in excess should be worked out by first breaking the excess production into slabs and then apportioning each slab between levy sugar and free sale sugar in the prescribed ratio; (ii) whether the assessee could, at the appellate stage, claim the benefit of the later judicial interpretation that the slabs must be computed with reference to excess production and not average production.

Issue (i): whether the rebate on sugar produced in excess should be worked out by first breaking the excess production into slabs and then apportioning each slab between levy sugar and free sale sugar in the prescribed ratio.

Analysis: The notification contemplated calculation of rebate with reference to excess production and different rebate rates depending on whether the quantity was levy sugar or free sale sugar. The correct method was to first divide the total excess production into the relevant slabs and then split each slab in the ratio of 65% levy sugar and 35% free sale sugar. The method adopted by the second Assistant Collector was wrong because he first separated levy sugar and free sale sugar and then computed the slabs by taking the combined base, which distorted the percentage-wise working.

Conclusion: The method followed by the second Assistant Collector was incorrect and had to be redone on the proper slab-wise basis.

Issue (ii): whether the assessee could, at the appellate stage, claim the benefit of the later judicial interpretation that the slabs must be computed with reference to excess production and not average production.

Analysis: The assessee's original refund claim remained founded on the same notification and on the same factual figures of average and excess production. The later interpretation did not introduce any new factual basis but only supplied the correct legal basis for quantifying the rebate. Since the claim involved a question of law and no change in the factual foundation, the benefit of the subsequently accepted interpretation could be applied even at the appellate stage.

Conclusion: The assessee was entitled to the benefit of the later interpretation and to have the rebate recalculated accordingly.

Final Conclusion: The rebate was required to be recomputed by treating the slabs as percentages of excess production and consequential relief was directed on that basis.

Ratio Decidendi: Where a refund or rebate claim rests on the same factual foundation, a subsequent and more favourable legal interpretation of the governing notification may be applied at the appellate stage, and rebate under such a notification must be computed on the basis of excess production where that is the true legal measure.
