Issues:
- Consideration of refund claims filed by M/s GMR Energy Vemagiri Power Generation Limited
- Whether the refund claims are hit by limitation
- Interpretation of the doctrine of unjust enrichment

Analysis:
1. Consideration of Refund Claims:
The judgment revolves around the consideration of refund claims filed by M/s GMR Energy Vemagiri Power Generation Limited. The appellant entered into an agreement with Korea Plant Service & Engineering Company Limited for operation and maintenance of a power plant. The appellant filed refund claims for the service tax paid to KPS, arguing that the service tax liability on the operation portion of the contract is not taxable. The Tribunal found merit in the appellant's argument, citing previous Tribunal orders and held that the appellant is eligible for filing refund claims as they have borne the effect of the service tax paid.

2. Limitation of Refund Claims:
The issue of whether the refund claims are hit by limitation was also addressed in the judgment. The adjudicating authority had held that the refund claims were time-barred based on the date of payment to KPS. However, the Tribunal disagreed with this finding, stating that since the service tax liability on the operation charges is not due to the government, the provisions of Section 11B of the Central Excise Act, 1944 do not apply. Citing a Bombay High Court case, the Tribunal concluded that the limitation period does not apply to refund claims based on service tax paid under a mistake of law.

3. Doctrine of Unjust Enrichment:
The judgment further delved into the interpretation of the doctrine of unjust enrichment. The Revenue argued that the doctrine was not satisfied as the power purchase agreement with APSEB included the service tax element in the unit price of electricity. However, the appellant provided a detailed Chartered Accountant certificate, which indicated the bifurcation of amounts and confirmed that the appellant had not passed on the service tax liability. Relying on a Delhi High Court case, the Tribunal found in favor of the appellant, holding that the doctrine of unjust enrichment was not applicable in this case.

In conclusion, the Tribunal accepted the appeals filed by M/s GMR Energy Vemagiri Power Generation Limited, set aside the impugned orders, and rejected the appeals filed by Revenue. The judgment emphasized the eligibility of the appellant for filing refund claims, the inapplicability of limitation due to the nature of the service tax liability, and the satisfaction of the doctrine of unjust enrichment based on the evidence provided.
