Issues: Whether redemption fine imposed in lieu of confiscation can be included while estimating the amount payable under the Sabka Vishwas (Legacy Dispute Resolution) Scheme, 2019.

Analysis: Redemption fine levied under Rule 25 of the Central Excise Rules, 2002, in lieu of confiscation, forms part of the recoverable amount in arrears along with excise duty for purposes of the Scheme. The Scheme's eligibility provisions do not make a declarant ineligible merely because redemption fine remains unpaid. The departmental clarification requiring prior payment of redemption fine is inconsistent with the Scheme.

Conclusion: Redemption fine cannot be included in the estimated amount payable under the Scheme; its inclusion was quashed and the payable amount must be recalculated after excluding the redemption fine. This is in favour of the assessee.

Issues: Whether the marketing and promotional services rendered by the assessee qualified as export of service under the Export of Service Rules, 2005.

Analysis: The Revenue's grounds substantially reiterated the contentions raised before the authorities below. The Tribunal's finding that the services fell within Rule 3(1)(iii) of the Export of Service Rules, 2005, read with the applicable Board circular, remained unassailed by any ground warranting interference. The precedent relied upon by the Revenue did not support its challenge, as the comparable issue had been resolved in favour of the assessee.

Conclusion: The services were correctly treated as export of service; the finding is in favour of the assessee.

Issues: (i) Whether service tax erroneously paid by the service provider under Mining Service for supply of floating rigs could be refunded to the service recipient without the service provider challenging the assessment; (ii) Whether the one-year limitation for refund claims applied where tax was paid under a mistake of law; (iii) Whether the respondent established absence of unjust enrichment; (iv) Whether the appellate authorities and the Tribunal had jurisdiction to grant refund for tax paid under a mistake of law.

Issue (i): Whether service tax erroneously paid by the service provider under Mining Service for supply of floating rigs could be refunded to the service recipient without the service provider challenging the assessment.

Analysis: Supply and operation of floating rigs was classifiable as Supply of Tangible Goods Service, which became taxable only from 16.05.2008, and not as Mining Service for the disputed period. The tax passed on by the service provider to the recipient was consequently collected without legal authority. The recipient, having borne the tax incidence, was entitled to seek its refund notwithstanding that the service provider had not separately challenged the classification assessment.

Conclusion: The service recipient was eligible for refund of service tax erroneously paid under Mining Service; this issue was decided in favour of the assessee.

Issue (ii): Whether the one-year limitation for refund claims applied where tax was paid under a mistake of law.

Analysis: Retention of tax collected through an erroneous classification, where no levy was legally attracted, was inconsistent with Article 265 of the Constitution of India. The limitation under Section 11B was held inapplicable to refund of service tax paid through ignorance or mistake of law.

Conclusion: The refund claim was not barred by limitation; this issue was decided in favour of the assessee.

Issue (iii): Whether the respondent established absence of unjust enrichment.

Analysis: Certificates of the service provider and the entity for whom the exploration activity was undertaken supported the finding that the service tax burden had been passed to and borne by the respondent. The concurrent factual finding on the absence of further passing on of the incidence was not shown to warrant interference.

Conclusion: Refund to the respondent would not result in unjust enrichment; this issue was decided in favour of the assessee.

Issue (iv): Whether the appellate authorities and the Tribunal had jurisdiction to grant refund for tax paid under a mistake of law.

Analysis: As the appeal proceedings contained established findings on erroneous classification, payment of tax, and the incidence borne by the respondent, requiring recourse to a civil suit or writ petition would be futile. The statutory appellate authorities were competent to rectify the classification error and order refund in the circumstances.

Conclusion: The appellate authorities and the Tribunal had jurisdiction to grant the refund; this issue was decided in favour of the assessee.

Final Conclusion: Tax collected on supply of floating rigs before the taxable entry for Supply of Tangible Goods Service came into force was liable to be refunded to the recipient who bore its incidence, without limitation or unjust-enrichment impediment.

Ratio Decidendi: Tax paid under an erroneous classification where no lawful levy existed cannot be retained consistently with Article 265, and a recipient who proves that it bore the incidence may obtain refund notwithstanding the ordinary limitation provision.

Issues: Whether towers and pre-fabricated buildings used for providing mobile telecommunication services qualify as inputs eligible for CENVAT credit.

Analysis: Towers and pre-fabricated buildings are goods rather than immovable property. Though they do not themselves transmit signals, they are indispensable to the effective functioning and positioning of antennas, creating a close and inseparable nexus with the provision of mobile telecommunication service. The expression "used for providing any output service" under Rule 2(k) covers such goods and is not confined to items directly transmitting signals.

Conclusion: Towers and pre-fabricated buildings used for mobile telecommunication services qualify as inputs under Rule 2(k) of the Cenvat Credit Rules, 2004, and CENVAT credit is admissible to the assessee.

Issues: Whether CENVAT credit could be denied solely because the recipient's address in input-service invoices did not match the address in its ST-2 registration certificate.

Analysis: The impugned demand proceeded exclusively on the invoice-address discrepancy without determining the substantive eligibility of the credit. The invoices otherwise contained the particulars required under Rule 4A of the Service Tax Rules, 1994. The differing address originated from an address retained in the service provider's accounting system, and the adjudicating authority did not address the assessee's explanation or objections. Denial of credit on that technical basis, without examination of entitlement on merits, was unsustainable.

Conclusion: The denial of CENVAT credit and the consequential demand, interest and penalty based solely on the address discrepancy were set aside in favour of the assessee, with the matter requiring fresh adjudication after notice and hearing.

Issues: Whether a subcontractor providing approved taxable services for authorised operations of a Special Economic Zone unit is entitled to exemption under Notification No. 9/2009-Service Tax despite the certificate being issued in the main contractor's name and non-submission of Form A-1.

Analysis: Notification No. 9/2009-Service Tax exempts taxable services provided in relation to authorised SEZ operations. The services rendered were approved services for the authorised operations of the SEZ unit. The certificate issued to the main contractor through whom the services were supplied sufficiently established compliance with the requirement that the services be provided to an authorised person. The Form A-1 requirement was introduced only from 01.03.2011, while the demand covered a period commencing in 2009; in any event, that requirement was procedural. A minor procedural lapse could not defeat the substantive exemption.

Conclusion: The subcontractor was entitled to the SEZ service-tax exemption under Notification No. 9/2009-Service Tax, and the exemption could not be denied for non-compliance with the procedural Form A-1 requirement.

Issues: Whether an appeal challenging classification and taxability of services was maintainable before the High Court under Section 35G(1) of the Central Excise Act, 1944.

Analysis: Section 35G(1) excludes High Court jurisdiction over Tribunal orders relating to determination of questions having a relation to the rate of duty or value for assessment. Classification of services bears a direct and proximate relation to the applicable rate of duty. Section 35L(2) clarifies that questions of taxability or excisability fall within questions relating to the rate of duty, and this clarification operates declaratorily. The proposed questions themselves concerned classification and taxability of the secondment arrangements; the contrary precedent relied upon concerned materially different facts.

Conclusion: The appeal was not maintainable under Section 35G(1) of the Central Excise Act, 1944; an appeal on the classification and taxability questions lay before the Supreme Court under Section 35L of that Act.

Issues: (i) Whether the writ petition could be entertained despite the statutory appellate remedy; (ii) Whether the service-tax adjudication on a works contract was sustainable without determining the service component under the prescribed valuation mechanism and without deciding the assessee's eligibility for reverse-charge treatment.

Issue (i): Whether the writ petition could be entertained despite the statutory appellate remedy.

Analysis: Availability of an appellate remedy is a rule of self-imposed restraint in writ jurisdiction and not an absolute jurisdictional bar. The challenge concerned the foundational basis of the assessment, including alleged non-consideration of applicable valuation provisions, notification-based liability, and constitutional limits on taxing works contracts, rather than mere quantification.

Conclusion: The writ petition was maintainable despite the alternative statutory remedy, in favour of the assessee.

Issue (ii): Whether the service-tax adjudication on a works contract was sustainable without determining the service component under the prescribed valuation mechanism and without deciding the assessee's eligibility for reverse-charge treatment.

Analysis: A works contract contains distinct goods-transfer and service elements. Rule 2A requires determination of the taxable service portion after excluding the value of property in goods transferred in execution of the contract, or application of the prescribed valuation percentages where applicable. The adjudication order did not meaningfully address this mechanism, the constitutional limitation concerning transfer of property in goods, or the relevant notification. Further, where applicability of reverse charge depended on whether the assessee was a partnership firm or a company, the adjudicating authority was required to ascertain that foundational fact and record a clear finding. A quasi-judicial order must deal with substantial contentions through reasoned findings.

Conclusion: The adjudication order was unsustainable for failure to decide material valuation and notification issues through a reasoned determination, in favour of the assessee.

Final Conclusion: Service-tax liability on the works contracts must be determined afresh by applying the statutory valuation framework, deciding the assessee's status and notification eligibility, and giving a reasoned hearing-based determination.

Ratio Decidendi: Where an assessment of a composite works contract fails to address the statutory method for isolating the taxable service component and other foundational notification issues, the resulting quasi-judicial order cannot stand for want of reasoned adjudication.

Issues: Whether a refund of service tax paid by a manpower service provider, though tax was payable by the recipient under the reverse charge mechanism, could be denied as time-barred despite the Department having recovered the same tax twice.

Analysis: From 01.04.2015, manpower supply services were subject to complete reverse charge, and the petitioner was not liable to collect or deposit service tax. The Department nevertheless retained the amount deposited by the petitioner and subsequently recovered tax on the same services from the recipient. The petitioner became aware of the erroneous collection only upon receipt of the recipient's debit note. In these exceptional circumstances, retention of the duplicated tax collection constituted unjust enrichment by the Department, and the statutory limitation could not defeat restitution. Exercise of writ jurisdiction was warranted notwithstanding the appellate remedy.

Conclusion: The refund claim could not be rejected as barred by limitation; the petitioner was entitled to refund of the amount wrongfully retained by the Department.

Issues: Whether the determination that service tax already paid could not be adjusted or refunded was premature before classification of the contract as a works contract or a service contract.

Analysis: The tax incidence and the nature of the tax payable depended on the Assessing Authority's determination of the character of the contract. Since that classification was still to be undertaken pursuant to the remand, a definitive ruling on adjustment or refund of service tax introduced an impermissibly speculative element. The parties agreed that this question should remain for consideration by the appropriate authority after completion of the classification exercise.

Conclusion: The prior finding denying adjustment or refund of service tax was premature and was vacated; the question remains open for determination by the appropriate authority after classification of the contract.

Issues: Whether an asserted error in the earlier judgment could be rectified through review.

Analysis: The observations in the earlier judgment were found to be fact-specific and consistent with its overall findings. Review jurisdiction under Order 47 Rule 1 does not permit rectification merely because the earlier judgment is alleged to be incorrect.

Conclusion: An allegedly incorrect judgment cannot be rectified in review proceedings.

Outcome: Writ petition dismissed as withdrawn with liberty to pursue the statutory appellate remedy before the CESTAT.
