Court dismisses Revenue's appeal citing Doctrine of unjust enrichment inapplicable to PSUs. Precedent upheld.

The court dismissed the appeal by the Revenue as the Doctrine of unjust enrichment was found to be inapplicable to Public Sector Undertakings (PSUs) in this case. The court relied on the precedent set in Mafatlal Industries Ltd. v. Union of India and noted that the duty incidence had not been passed on to any other person. As the respondent was a PSU, the court upheld the decision of the authorities, finding no illegality or perversity in their determination.

Judgment Details:

*Issue 1: Application of Unjust Enrichment Principle to PSUs*

The appellant, Revenue, challenged the excess payment refund claimed by the respondent, a PSU, on the grounds of unjust enrichment. The original authority and the Commissioner (Appeals) both examined the claim and held that the duty incidence had not been passed on to any other person. The CESTAT dismissed the appeal, stating that the Doctrine of unjust enrichment is not applicable to PSUs, citing the authority in Mafatlal Industries Ltd. v. Union of India. The court agreed with the CESTAT's decision, noting that no material was presented to show a reversal or modification of the principle established in Mafatlal Industries. As the Shipping Corporation is a PSU, the court found no illegality or perversity in the decision of the authorities.

*Result:*
The appeal by the Revenue is dismissed as the Doctrine of unjust enrichment was held inapplicable to PSUs in this case, in line with the authorities cited and the nature of the claimant being a PSU.
