Excise refund for duty paid under mistake of law allowed in writ, but post-sale interest not deductible from wholesale price.

Refund of excise duty paid under a mistake of law may be entertained in writ jurisdiction despite departmental limitation, where the assessee acts within a reasonable time after discovering the mistake; the refund claims for freight, octroi and additional tax on sales tax were therefore allowed. By contrast, interest arising from post-sale credit arrangements was held not deductible from wholesale price for assessable value, because it was not part of any pre-arranged discount structure at the time of removal of goods. The writ petition thus succeeded only on the refund issue and failed on deduction of interest on bills of exchange.

Issues: (i) whether the refund claims for freight, octroi and additional tax on sales tax were barred by limitation or could be entertained in writ jurisdiction; and (ii) whether interest on bills of exchange could be deducted from the wholesale price for determining the assessable value under excise law.

Issue (i): whether the refund claims for freight, octroi and additional tax on sales tax were barred by limitation or could be entertained in writ jurisdiction.

Analysis: The claim arose from excess excise duty paid under a mistake of law, discovered when the legal position on inclusion of post-manufacturing expenses was clarified. The Court treated the petition as one seeking refund of duty paid under such mistake and held that the departmental rejection on limitation under the refund provision did not preclude relief in writ jurisdiction. The doctrine of laches was considered, but the petition had been filed within a reasonable time after discovery of the mistake, and no part of the claim on the items accepted by the departmental authority was found to be defeated on limitation.

Conclusion: The refund claims on freight, octroi and additional tax on sales tax were not barred by limitation and were allowed in favour of the assessee.

Issue (ii): whether interest on bills of exchange could be deducted from the wholesale price for determining the assessable value under excise law.

Analysis: The Court distinguished the precedent dealing with cash discount, noting that in the present case there was no pre-arranged price list or known discount structure at the time of removal of the goods. The credit facility arose only after the sale in particular cases, and the interest burden was therefore not part of the wholesale price as contemplated for assessable value. It was not a deductible element on the facts of the case.

Conclusion: Interest on bills of exchange was not deductible from the wholesale price and the assessee's claim on this item failed.

Final Conclusion: The petition succeeded only to the extent of refund of excess duty on freight, octroi and additional tax on sales tax, while the claim for deduction of interest on bills of exchange was rejected.

Ratio Decidendi: A refund claim for excise duty paid under a discovered mistake of law may be entertained in writ jurisdiction despite the departmental limitation period, where the petition is pursued without unreasonable delay; but interest arising from post-sale credit arrangements is not a deductible element of wholesale price for assessable value.
