The case involves M/s Addison & Co. Ltd., a cutting tools manufacturer, seeking a refund of excise duty paid on taxes and discounts. Initially rejected, the company's refund claim was ... later upheld by the Collector of Central Excise Appeals. Dispute arose regarding whether the company passed on duty burden to buyers and eligibility for post-clearance refunds. Interpretation of relevant provisions of the Central Excise Act, especially Sections 11B and 12B, was central. The High Court of Madras ruled in favor of the company, leading to the appeal before the Supreme Court (Civil Appeal No. 7906 of 2002).
