Issues:
Refund of service tax paid during March 2005 to November 2005, limitation period for refund claims, unjust enrichment in service tax payment.

Analysis:
1. Refund of Service Tax Paid: The appellant filed refund claims for service tax paid on a contract with ONGC. The appellant argued that the service tax liability did not arise as the contract was a turn-key project and not taxable before 01.06.2007. The lower authorities rejected the refund claim citing limitation and unjust enrichment issues.

2. Limitation Period for Refund Claims: The tribunal found that the service tax paid in March 2005 and May 2005 was outside the limitation period as per Section 11B of the Central Excise Act, 1944. The appellant did not deposit the amounts under protest, leading to the rejection of the refund claims for these periods.

3. Unjust Enrichment in Service Tax Payment: Regarding the service tax paid in September 2005 and November 2005, the tribunal noted that the appellant calculated the tax liability from the lump-sum contract amount received from ONGC. As the appellant received the full contracted amount, it was deemed that they had collected the service tax from ONGC. The tribunal dismissed the argument that the service tax liability did not arise based on the contract entered, as the appellant had voluntarily calculated and paid the tax.

4. Judgment: The tribunal upheld the lower authorities' decision, rejecting the appeal for refund of service tax paid during March 2005 to November 2005. The tribunal found no merit in the appellant's contentions and affirmed the impugned order. The appeal was dismissed accordingly.
