Appellant entitled to Rs.1.52 crore service tax refund under Section 103 but matter remanded for unjust enrichment examination

CESTAT Bangalore held that appellant is entitled to service tax refund of Rs.1,52,17,889/- under Section 103 of Finance Act, 1994, but only for invoices raised between 01.04.2015 and 29.02.2016. Refund of Rs.31,67,199/- for invoices before 01.04.2015 and after 29.02.2016 was denied as services were not rendered during the specified period. The construction contracts qualified as "original works" eligible for refund. However, matter was remanded to adjudicating authority to examine unjust enrichment principles, requiring appellant to submit additional documents proving refund amount was not passed on to others. Appeal disposed off with partial relief granted.

The core legal questions considered by the Tribunal are:

(i) Whether the refund of service tax amounting to Rs.1,52,17,889/- is admissible under Section 103 of the Finance Act, 1994, given the nature of services provided, the period of service tax payment, and the contractual framework;

(ii) Whether the refund amount is barred by the principle of unjust enrichment, considering the accounting treatment of service tax paid and the possibility of burden being passed on to customers.

Issue-wise Detailed Analysis:

1. Admissibility of Refund under Section 103 of the Finance Act, 1994

Relevant Legal Framework and Precedents: Section 103, introduced by the Finance Act, 2016, provides a special exemption for service tax levied on services related to construction, erection, commissioning, or installation of original works pertaining to airports or ports under contracts entered into before 1st March 2015, where appropriate stamp duty has been paid. It specifies that no service tax shall be levied or collected during the period from 1st April 2015 to 29th February 2016 for such services, and refund shall be made for any service tax collected during this period. The refund claim must be filed within six months from the date of assent of the Finance Bill, 2016.

Section 66B and Section 68 of the Finance Act, 1994, govern the levy and payment of service tax, respectively. The Point of Taxation Rules, 2011, particularly Rules 2(e), 3(a), and 4A of the Service Tax Rules, 1994, define the point of taxation as the time when the invoice is issued or payment received, and prescribe timelines for invoice issuance, especially in cases of continuous supply of services.

Court's Interpretation and Reasoning: The Tribunal observed that the service tax exemption under Section 103 applies strictly to the period from 01.04.2015 to 29.02.2016. The invoices issued prior to 01.04.2015 and after 29.02.2016, even if related to contracts entered into before 01.03.2015, fall outside this period and thus are not eligible for refund. The Tribunal emphasized that the point of taxation rules determine when the service is deemed to have been provided, which is generally the invoice date or completion of the event under continuous supply of service contracts. Since the invoices outside the specified period do not correspond to service provision within the exemption window, the refund claim on those invoices is rightly rejected.

The Tribunal further analyzed the definition of "original works" as per Rule 2A of the Service Tax (Determination of Value) Rules, 2006. It held that contracts involving new construction, additions, alterations to abandoned or damaged structures, and erection, commissioning, or installation of plant or machinery qualify as original works. The Tribunal found that contracts for expansion of terminals, construction of new facilities, and refurbishment involving civil and interior works fall within this definition, thereby entitling the appellant to refund of service tax paid on such original works during the specified period.

Key Evidence and Findings: The appellant submitted master contracts entered into before 01.03.2015, purchase orders issued pursuant to these contracts, and invoices raised against the purchase orders. Although some invoices did not explicitly reference the master contracts, the appellant provided a detailed worksheet correlating invoices, purchase orders, and contracts. The Tribunal accepted this correlation in absence of any contradictory evidence from the Revenue.

Application of Law to Facts: The Tribunal applied the statutory provisions and rules to the facts, affirming that only service tax paid on invoices dated within the exemption period qualifies for refund. It also recognized the appellant's entitlement to refund for services relating to original works as defined, rejecting the Revenue's contention that refurbishment works do not qualify.

Treatment of Competing Arguments: The Revenue argued that invoices must explicitly reference contracts entered before 01.03.2015 for refund eligibility, and that refurbishment works do not constitute original works. The Tribunal rejected these contentions, holding that correlation through purchase orders suffices and that refurbishment involving civil and interior works is covered under original works. The appellant's reliance on Point of Taxation Rules to assert refund eligibility for invoices outside the specified period was also rejected based on the temporal scope of Section 103.

Conclusion: Refund is admissible only for service tax paid on invoices dated between 01.04.2015 and 29.02.2016 relating to original works under contracts entered before 01.03.2015. Refund claims for invoices outside this period are not maintainable.

2. Applicability of the Principle of Unjust Enrichment to the Refund Claim

Relevant Legal Framework and Precedents: The principle of unjust enrichment bars refund where the claimant has passed on the burden of tax to others, meaning the claimant has not borne the economic cost. The appellant relied on a Chartered Accountant certificate stating no unjust enrichment, referencing a Supreme Court decision holding refund admissible where service tax was paid during exemption period. The Revenue cited prior Tribunal decisions and regulatory orders indicating that fees charged by the appellant are regulated and likely include the tax burden.

Court's Interpretation and Reasoning: The Tribunal noted that the appellant had accounted for the service tax paid as an expenditure in their Profit & Loss Account, which prima facie suggests the burden may have been passed on to customers. The appellant did not submit detailed financial documents to establish that the tax burden was not recovered from customers. The Revenue referred to the Airports Economic Regulatory Authority order fixing aeronautical tariffs and user development fees (UDF), implying that the tax cost may have been factored into regulated fees.

The Tribunal found the Chartered Accountant certificate insufficiently detailed to conclusively negate unjust enrichment. It recognized the need for a thorough examination of whether the appellant absorbed the tax cost or passed it on.

Key Evidence and Findings: The appellant's P&L Account showed the service tax as expenditure; no further documents were submitted to demonstrate non-passing of tax burden. The regulatory order indicated fees are fixed by statutory authorities, which could incorporate the tax cost.

Application of Law to Facts: Given the lack of conclusive evidence from the appellant and the regulatory framework, the Tribunal remanded the issue to the adjudicating authority for fresh examination. The appellant was directed to submit further documents to establish non-passing of the tax burden.

Treatment of Competing Arguments: The appellant argued that the tax was expensed due to non-eligibility of cenvat credit and that fees are regulated, not reflecting passed-on tax. The Revenue countered with accounting evidence and regulatory orders suggesting the tax burden was passed on. The Tribunal found both sides' arguments plausible but requiring detailed fact-finding.

Conclusion: The issue of unjust enrichment remains open and is remanded for further adjudication based on additional documentary evidence to be submitted by the appellant.

Significant Holdings:

"A plain reading of the said provision makes it clear that service tax shall not be levied or collected during the period from 1st day of April 2015 to 29th day of February, 2016 in respect of services provided by way of construction, erection, commissioning or installation of original works pertaining to an airport or port under a contract."

"The invoices raised before 01.04.2015 and after 29.02.2016 cannot fall within the scope of refund of service tax under Section 103 of the Finance Act, 1994 since as per the said Rules the service had not been rendered during the period specified."

"The construction services under various contracts would definitely come under the scope of 'original works' and accordingly admissible to refund of service tax paid under the Section 103 of the Finance Act, 1994."

"Once the appellant could able to correlate the contract with particular invoices linking through the individual purchase orders, we do not find any reason not to accept the same and deny refund of the service tax paid on such invoices solely on the ground that the invoices do not reflect the contracts."

"The matter needs to be remanded to the adjudicating authority and the appellant is directed to submit further documents to establish the fact that the refund amount has not been passed on to others."

The Tribunal's final determinations are:

(i) Refund is admissible only for service tax paid on invoices dated within 01.04.2015 to 29.02.2016 relating to original works under contracts entered before 01.03.2015;

(ii) Refund claims for invoices outside this period are rejected;

(iii) The issue of unjust enrichment is remanded for fresh adjudication with directions to the appellant to submit additional evidence demonstrating that the tax burden was not passed on to customers.
