Money paid under mistake on exempt excise goods is recoverable; limitation did not defeat the civil refund claim.

Goods manufactured and cleared before 21-5-1976 were treated as speciality oils exempt from excise duty on the evidence, trade notice, and departmental material, and the taxpayer succeeded on that issue. Duty paid on those exempt clearances was held to have been paid under a bona fide mistake, so the amount was recoverable as money paid under mistake under Section 72 of the Indian Contract Act, 1872. The refund claim and suit were also held to be in time, because the mistake-based claim was not defeated by the special excise limitation and the departmental proceedings period was treated as excludable. The plaintiff was therefore entitled to refund, with appropriate adjustment and interest.

Issues: (i) whether the goods manufactured and cleared before 21-5-1976 were speciality oils exempt from excise duty; (ii) whether the excise duty paid on those clearances was paid under a mistake; (iii) whether the refund claim and suit were barred by limitation.

Issue (i): whether the goods manufactured and cleared before 21-5-1976 were speciality oils exempt from excise duty.

Analysis: The evidence and the departmental proceedings showed that the product fell within the exempted speciality oil category under the trade notice. The appellate order had also indicated that records, dispatch particulars, and chemical testing could support the claim, and the later departmental order accepted the exemption position at least in part. The defendants led no oral evidence to dislodge the plaintiff's case.

Conclusion: The issue was decided in favour of the plaintiff.

Issue (ii): whether the excise duty paid on those clearances was paid under a mistake.

Analysis: The payment was made on a mistaken understanding that the product attracted duty. The trade notice and the subsequent departmental acceptance showed that the duty had been paid on goods that were exempt, bringing the case within the principle of money paid under mistake. Section 72 of the Indian Contract Act, 1872 was applied to hold that money so paid is refundable.

Conclusion: The issue was decided in favour of the plaintiff.

Issue (iii): whether the refund claim and suit were barred by limitation.

Analysis: The refund application was filed soon after the plaintiff learnt of the trade notice and the mistaken payment. The Court held that the special excise limitation did not defeat a claim based on mistake in the facts of the case, and the period spent in the departmental proceedings was treated as excludable for limitation purposes. The suit was therefore held to be within time.

Conclusion: The issue was decided in favour of the plaintiff.

Final Conclusion: The plaintiff was entitled to refund of the excise duty wrongly paid, with appropriate adjustment and interest, and the suit succeeded substantially.

Ratio Decidendi: Money paid towards excise duty under a bona fide mistake on exempt goods is recoverable under Section 72 of the Indian Contract Act, 1872, and the special refund limitation will not defeat a civil claim where the payment was made under mistake and the claim is otherwise within the general period of limitation.
