Excise refund claims cannot be defeated by limitation alone, but remain subject to unjust enrichment verification.

Refund claims under excise law could not be rejected merely because they were filed beyond the prescribed six-month period, as the Court followed the view that limitation should not be used to defeat an otherwise just claim. The petitioners were therefore entitled to refund on that ground. However, refund remained subject to the proviso to Section 11B embodying unjust enrichment, and the authorities were permitted to re-examine whether the duty burden had been passed on to consumers. Refund could be denied only if that statutory condition was satisfied.

Issues: (i) Whether the refund claims could be rejected on the ground of limitation. (ii) Whether refund was subject to the proviso against refund where the burden of duty had been passed on to consumers.

Issue (i): Whether the refund claims could be rejected on the ground of limitation.

Analysis: The refund applications were admittedly beyond the prescribed six-month period, but the Court followed the earlier Division Bench view that the plea of limitation should not be invoked by the State to defeat an otherwise just refund claim. The rejection of refund solely on limitation was therefore not sustainable.

Conclusion: The petitioners were entitled to refund and the refund could not be denied on the ground of limitation.

Issue (ii): Whether refund was subject to the proviso against refund where the burden of duty had been passed on to consumers.

Analysis: The Court held that the statutory proviso to Section 11B embodied the principle of unjust enrichment, under which refund is unavailable if the duty burden has already been passed on. The authorities were therefore permitted to examine that aspect afresh while passing a new order in accordance with law.

Conclusion: Refund remained subject to verification under the proviso to Section 11B, and could be denied only if the burden had been passed on to consumers.

Final Conclusion: The petition was allowed, the limitation objection was rejected, and the matter was left to the authorities to re-examine entitlement to refund on the statutory principle of unjust enrichment.

Ratio Decidendi: A refund claim under the excise law cannot be defeated merely by limitation if the State ought not to invoke that plea to defeat a just claim, but refund remains barred where the statutory condition against unjust enrichment is attracted.
