The Madras High Court has held that service tax erroneously collected on the supply and operation of floating rigs for petroleum exploration under the category of “Mining Services” was liable to be refunded when the correct taxable classification was “Supply of Tangible Goods Service”, which became taxable only from May 16, 2008.
The Bench of Justice G. Jayachandran and Justice N. Mala has observed that the service tax paid by Aban Offshore was ultimately passed on to Hardy and that the factual findings of the appellate authorities and CESTAT established this position. Thus, the absence of a separate challenge by the service provider did not extinguish the recipient’s entitlement to refund where the underlying levy itself was found to be legally unsustainable.

The dispute arose against the backdrop of the Supreme Court’s decision in Union of India v. Indian National Shipowners Association (INSA). The Supreme Court had affirmed the view that services relating to the supply of floating rigs were classifiable under “Supply of Tangible Goods Service” rather than “Mining Services.”
The Madras High Court noted that the legal position flowing from the INSA decision was decisive in determining the classification applicable to the transaction involving Hardy Exploration & Production.
The Court observed that the supply of floating rigs in the course of oil extraction was brought under the taxable category of Supply of Tangible Goods Service only with effect from May 16, 2008. Therefore, service tax collected for the earlier period under the classification of Mining Services was not legally sustainable.
The petitioner was engaged in petroleum exploration pursuant to a production sharing contract with ONGC for extraction of crude oil.
For its exploration activities, Hardy entered into an agreement with Aban Offshore Ltd. for the supply and operation of floating rigs. Aban Offshore charged service tax from Hardy under the head “Mining Services” and deposited the tax with the Department.
The payment of the tax by Aban Offshore to the Government was not in dispute. The dispute concerned whether the tax had been legally leviable during the relevant period.
Hardy subsequently sought refund of the service tax paid for the period June 1, 2007 to May 15, 2008, contending that the service relating to supply of floating rigs was taxable under the subsequently introduced category of Supply of Tangible Goods Service only from May 16, 2008.
Consequently, according to Hardy, there was no statutory authority for collecting service tax on the transaction during the earlier period.
The original adjudicating authority rejected Hardy’s refund claim.
One of the reasons was that Aban Offshore, which had actually paid the service tax under the Mining Services classification, had not disputed the classification or challenged the assessment. The authority also relied upon limitation and questioned whether Hardy had produced sufficient evidence to establish that the incidence of tax had not been passed on.
The authority further noted the absence of a disclaimer certificate from Aban Offshore.
Hardy challenged the decision before the appellate authority.
The Commissioner (Appeals), however, accepted Hardy’s case and held that the supply of floating rigs for post-extraction work was covered by Supply of Tangible Goods Service. Since that category became taxable only from May 16, 2008, the assessee was held entitled to refund of the tax paid before that date.
The department then approached the CESTAT.
The CESTAT confirmed the appellate authority’s finding that the supply of floating rigs was classifiable as Supply of Tangible Goods Service and not Mining Services.
The Tribunal also held that the service recipient could claim refund even though the service provider had not separately challenged the original classification.
Relying on judicial precedents, including the decisions concerning Indian National Shipowners Association, Micromax Informatics, and other cases, the Tribunal concluded that the service provider’s failure to challenge the classification did not prevent the recipient from seeking refund of tax that had been wrongly passed on to it.
The department challenged this order before the Madras High Court.
The Department questioned, among other things, whether Hardy, as a service recipient, could claim refund when the service provider had not disputed the assessment.
The department also argued that the refund claim was barred by limitation under Section 11B of the Central Excise Act, 1944, read with Section 83 of the Finance Act, 1994.
The Department further questioned whether Hardy had discharged the burden of establishing that the tax burden had not been passed on, and whether the lower appellate authorities were correct in relying upon certificates and invoices to conclude that there was no unjust enrichment.
Another important contention was based on the Supreme Court’s decision in Mafatlal Industries, with the Revenue arguing that the assessee’s remedy was by way of a civil suit or writ petition rather than through statutory refund proceedings.
Appearing for the Department, the Senior Standing Counsel relied upon the Supreme Court’s decision in Collector of Central Excise, Kanpur v. Flock (India) Pvt. Ltd.
The department argued that where an assessment order is appealable, the aggrieved party must challenge that order through the statutory appellate mechanism. According to the Department, a subsequent refund application could not be used as a means of indirectly challenging an assessment that had attained finality.
Reliance was also placed on Priya Blue Industries Ltd. v. Commissioner of Customs (Preventive), where the Supreme Court had held that a refund authority could not sit in appeal over an assessment order.
The Department contended that because Aban Offshore had not challenged the classification, the assessment remained operative and Hardy could not bypass the assessment process by filing a refund claim.
The High Court, however, rejected the Revenue’s contention in the factual circumstances of the case.
A crucial factor was that the very classification on which the tax had been collected was subsequently found to be legally incorrect. The Court noted that the Supreme Court had conclusively held that floating rigs were covered under Supply of Tangible Goods Service.
The High Court therefore treated the payment as one made under a mistake of law, rather than as a case where the assessee was merely attempting to reopen an otherwise valid assessment.
The Court held that the erroneous classification and consequent collection of service tax could not acquire the character of a lawful levy merely because the service provider had not separately challenged the assessment.
A central feature of the judgment is the Court’s reliance on Article 265 of the Constitution of India, which provides that:
“No tax shall be levied or collected except by authority of law.”
The Court held that the collection of service tax on floating rigs for the relevant pre-May 16, 2008 period was not legally sustainable after the correct classification had been established.
The Court reasoned that the Government could not retain an amount that had been collected as tax when there was no authority of law supporting such collection.
The judgment referred to the principles laid down by the Supreme Court in Mafatlal Industries v. Union of India, particularly concerning refunds arising from unconstitutional or illegal levies and mistakes of law.
The Revenue argued that Section 83 of the Finance Act, 1994, read with Section 11B of the Central Excise Act, prescribed a one-year limitation period for claiming refund.
The Department contended that Hardy’s claim for the earlier period was therefore time-barred.
The High Court rejected this argument.
It relied upon the line of judicial authority holding that where service tax has been paid due to a mistake of law, the statutory limitation under Section 11B cannot be used to justify retention of an amount that was never lawfully leviable.
The Court referred to its earlier decision in 3E Infotech v. CCE and the Bombay High Court’s decision in Parijat Construction v. CCE, Nashik, noting that the Supreme Court had affirmed the principle in Collector of C.E., Chandigarh v. Doaba Co-operative Sugar Mills.
The second substantial question of law relating to limitation was accordingly answered against the Department.
Another significant aspect of the judgment concerns the Department’s argument that only the service provider, Aban Offshore, could have challenged the tax payment.
The High Court found that argument unsustainable in the circumstances of the case.
The Court accepted that Hardy, as the service recipient that ultimately bore the tax burden, was entitled to seek refund of the amount erroneously collected.
The Court also examined the doctrine of unjust enrichment.
The Department questioned whether Hardy had adequately demonstrated that the burden of service tax had not been passed on to another person.
The Court noted that both the appellate authority and the CESTAT had considered the relevant certificates issued by Aban Offshore and CPCL. These documents supported the conclusion that the service tax burden had been borne by Hardy.
The Court therefore held that a refund to Hardy would not result in unjust enrichment.
On the contrary, the Court observed that retention by the Government of an amount collected under a mistake of law, without constitutional authority, would itself amount to unjust enrichment by the State and would be contrary to Article 265.
The Revenue had also challenged reliance on the CPCL certificate concerning the use of the floating rigs.
The High Court rejected the challenge, observing that the CPCL certificate had not been questioned before the appellate authority or the Tribunal.
The Court treated the validity and evidentiary value of the certificate as a question of fact and held that, in the absence of a proper challenge at the earlier stages, the Department could not merely raise suspicion regarding the certificate at the High Court stage.
The fourth substantial question of law was accordingly answered against the Department.
The Revenue’s reliance on Mafatlal Industries was also rejected.
The Department argued that the refund claim could only be pursued through a civil suit or writ petition and that the lower appellate authorities lacked jurisdiction to grant the refund.
The Madras High Court distinguished the factual situation in Mafatlal Industries from the case before it.
Here, the assessee’s appeal had already been entertained and allowed by the First Appellate Authority, and that order had subsequently been affirmed by the CESTAT on the basis of factual findings concerning the classification of the floating rigs and the passing on of the tax burden.
The Court therefore held that it would be futile to compel Hardy to institute separate civil or writ proceedings when the statutory appellate authorities had already adjudicated the dispute.
In a significant observation, the High Court held that the lower appellate authority and the Tribunal had jurisdiction to decide the grave classification error and order refund where the tax had been paid due to a mistake of law.
The Court emphasised that the factual circumstances were already established and there was no dispute regarding the classification of the floating rigs or the passing on of the tax burden.
Consequently, the assessee did not have to be relegated to separate civil or writ proceedings merely to obtain the refund.
