Refund suit for excise duty under alleged mistake of law barred when statutory refund route and limitation rules control.

A civil suit seeking refund of excise duty paid under an alleged mistake of law was held not maintainable where the claimant had to proceed under the statutory refund mechanism, as explained in Mafatlal Industries; the objection to maintainability succeeded. The court also held that Section 17(1)(c) of the Limitation Act could not extend limitation on the basis of discovering a mistake of law from a judgment in another person's case, especially where refund proceedings had already been pursued and failed; the suit was therefore time-barred. The appeal was allowed, the trial court decree was set aside, and the refund suit was dismissed.

Issues: (i) Whether a civil suit for refund of excise duty paid under a mistake of law was maintainable in view of the refund mechanism under the excise law. (ii) Whether the suit was within limitation by invoking discovery of mistake of law under the Limitation Act.

Issue (i): Whether a civil suit for refund of excise duty paid under a mistake of law was maintainable in view of the refund mechanism under the excise law.

Analysis: The governing principle applied was that a refund claim cannot be founded on a decision rendered in another person's case, and a party cannot treat such a decision as the discovery of its own mistake of law. The decision in Mafatlal Industries controlled the field and declared that refund claims of this nature are to be pursued under the statutory refund procedure. Where a claimant has already invoked the refund machinery and failed, the special direction for pending matters does not extend any further benefit.

Conclusion: The civil suit for refund was not maintainable, and the objection to maintainability succeeded against the assessee.

Issue (ii): Whether the suit was within limitation by invoking discovery of mistake of law under the Limitation Act.

Analysis: The applicable rule was that Section 17(1)(c) of the Limitation Act does not apply to refund claims of excise duty based on alleged discovery of mistake of law from another case. Once the statute and the binding precedent exclude that basis, the limitation clock cannot be extended on the footing of such discovery. The claimant had also already pursued refund proceedings and failed, which prevented reliance on the limited protective direction for pending cases.

Conclusion: The suit was barred by limitation, and the plea under the Limitation Act failed.

Final Conclusion: The appeal was allowed, the decree of the trial court was set aside, and the suit for refund of excise duty was dismissed.

Ratio Decidendi: A refund suit based on alleged discovery of mistake of law from a judgment in another person's case is not maintainable, and Section 17(1)(c) of the Limitation Act cannot be used to extend limitation for such a claim.
