Recipient entitled to refund of Swachh Bharat and Krishi Kalyan cesses paid on running-bill adjustments; s.11B objections disallowed

CESTAT (All.) (LB) allowed the appeal and remitted the matter. The Tribunal held the refund claim valid where a service provider charged Swachh Bharat and Krishi Kalyan cesses on running-bill adjustments though assessable value was taken as nil; the recipient who bore the burden is entitled to refund. The Technical Member's reliance on unrevised ST-3 returns could not be raised at Tribunal as it was absent from the show-cause notice. Time-bar and unjust-enrichment objections under s.11B were also not pleaded earlier, so Commissioner(A)'s partial rejection was in error.

ISSUES PRESENTED AND CONSIDERED

1. Whether Swachh Bharat Cess (SBC) and Krishi Kalyan Cess (KKC) charged on running/"zero-value" invoices issued after part-performance of continuous services (adjusting advances received and on which service tax/cesses had been paid earlier) were chargeable, and whether the recipient is entitled to refund of such amounts.

2. Whether a refund claim filed by the service recipient is maintainable where the service provider's self-assessed ST-3 returns have not been revised/modified to reflect the refund (i.e., whether non-revision of provider's ST-3 vitiates recipient's refund claim).

3. Whether limitation (Section 11B time bar) and unjust-enrichment defences can be invoked to deny/refuse refund when those grounds were not raised in the Show Cause Notice or Order-in-Original but were relied upon in the Order-in-Appeal.

ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Chargeability of SBC/KKC on zero-value running invoices (Point of Taxation analysis)

Legal framework: Point of Taxation Rules, 2011 (POTR) - definitions (Rule 2), determination of point of taxation (Rule 3), change in effective rate (Rule 4), payment on new levy (Rule 5) and continuous supply (Rule 6); Rule 4A of Service Tax Rules, 1994 (invoices for continuous supply); Sections introducing SBC and KKC and their saving/application clauses making Chapter V provisions applicable to those cesses.

Precedent treatment: Tribunal and High Court decisions were cited by the parties both ways (e.g., Vigyan Gurukul, Bajaj Allianz, Carrier Point, Indian Ispat Works) supporting the proposition that where advances were received and service tax discharged at that time, subsequent enhancement/new levy does not bite on amounts already received and taxed; revenue relied on Board clarifications and literal application of Rule 5 to running invoices issued after new levy.

Interpretation and reasoning: The Tribunal majority (Member (Judicial) joined by third Member) construed POTR and Service Tax Rules harmoniously: where advances were received and the service provider issued advance-invoices and discharged service tax/cess applicable on receipt, the point of taxation to the extent of advance is the date of receipt/advance-invoice (Rule 3 explanation and Rule 6/continuous supply). Running invoices issued after part performance that merely adjusted advances (resulting in net/"zero" taxable value) do not create a fresh point of taxation for the value of the advance. Rule 5 protects amounts where invoice issued and payment received before the service became taxable; Rules 3/4/6 together show that increases/new levies operate only on values not already taxed on receipt. The Appellate authority's interpretation that running invoices beyond 14 days from new levy attract SBC/KKC even where adjusted against earlier taxed advances was held to be a misconstruction rendering the deeming provisions otiose. The majority found consistent documentary evidence of advances, advance-invoices and tax payment on advances; where running invoices showed zero assessable value but still charged SBC/KKC, such cess collection lacked legal authority and was refundable.

Ratio vs. Obiter: Ratio - for continuous supply with advance receipts on which tax/cess was paid, point of taxation is date of receipt/advance-invoice; subsequent running invoices adjusting those advances cannot be re-taxed by application of later-introduced cesses on the adjusted (advance) portion. Obiter - discussion of particular Board circulars and their limits in cases of adjustment of advances.

Conclusion: SBC/KKC charged on zero-value running invoices adjusting advances paid (and taxed) prior to introduction of SBC/KKC were not chargeable; recipient entitled to refund of such amounts subject to other statutory limits/conditions (see Issues 2-3).

Issue 2 - Effect of non-revision of service provider's ST-3 returns on maintainability of recipient's refund claim

Legal framework: Section 11B (Central Excise Act) as applied to service tax refunds; concept of self-assessment under service tax law; rules and authorities recognizing that refund provisions are to be applied when the competent authority is satisfied that duty/cess was paid contrary to law.

Precedent treatment: Supreme Court authorities (Mafatlal, ITC Ltd., Priya Blue, Flock) and High Court decisions stress that refund proceedings cannot be used as a vehicle to re-open or re-adjudicate finalized self-assessment/assessment unless the assessment/self-assessment is questioned/revised through prescribed statutory avenues; ITC Ltd. emphasises that a self-assessed return is akin to assessment and refund processing cannot entail re-assessment; other Tribunal decisions allow refund where payment was without authority of law (distinct factual matrix).

Interpretation and reasoning: The learned Member (Technical) relied on the above authorities to conclude that until the service provider's ST-3 returns were revised/modified (or the self-assessment otherwise reopened), the refund claim could not be entertained because refund processing must not supplant reassessment proceedings. The Member (Judicial) disagreed on facts: he held that the issue was legal (cess not leviable on advances) and that the ground of non-revision of ST-3 was not raised in the Show Cause Notice or Order-in-Original (procedural bar to raising it at appellate/Tribunal stage); the majority (third Member) agreed with Member (Judicial) on procedural grounds and remitted for consequential order, noting that non-revision had not been pleaded/notified and thus could not defeat claimant at Tribunal stage.

Ratio vs. Obiter: Ratio (as applied by Member (Technical)) - established Supreme Court precedent requires that self-assessment/assessment normally be reopened through prescribed statutory mechanisms before refund denial based on reassessment; Obiter - whether that principle mandates automatic dismissal of recipient's claim when provider has not revised returns where the factual matrix shows payments clearly beyond authority of law.

Conclusion: Jurisprudential principle restricts refund processing from acting as reassessment; however, where non-revision of provider returns was not a ground in the SCN/Order-in-Original and the factual record shows payments on advances previously taxed, invoking non-revision at appellate/Tribunal stage is procedurally impermissible. The Tribunal (majority) held the non-revision ground could not be raised belatedly and did not preclude refund where the statutory point-of-taxation analysis favours the claimant.

Issue 3 - Time-bar (Section 11B limitation) and unjust enrichment raised at appellate stage though not in SCN/Order-in-Original

Legal framework: Section 11B (refund timeline), provisions and explanations concerning proof that incidence of tax was not passed on (unjust enrichment doctrine), and requirements in refund applications (documentary evidence, auditor certificates, ST-3s, challans); relevant Supreme Court dicta (Mafatlal) on unjust enrichment and requirement that claimant establish not passing on burden.

Precedent treatment: Mafatlal lays down that refund claims generally lie under Section 11B and that claimants must show they have not passed on the burden; decisions recognize time limitation and unjust enrichment as valid defences but also insist on procedural fairness (issues to be raised in SCN). ITC and other authorities indicate refund proceedings are not re-assessment vehicles.

Interpretation and reasoning: The Appellate authority relied on Section 11B limitation to hold that part of SBC refund (Rs.2,48,418) was time-barred because the refund application was made beyond one year from payment. It also applied unjust enrichment principle to deny/refuse portions where it concluded the recipient passed on the burden or failed to prove otherwise; however, the Tribunal majority found that unjust enrichment and time-bar were not grounds in the SCN/Order-in-Original and therefore could not be raised for the first time on appeal at Tribunal stage - procedural fairness requires that such defences be pleaded at the earliest opportunity so the claimant may meet them. The Tribunal thus limited consideration of these defences where they were not properly invoked below, while acknowledging statutory applicability of limitation and unjust enrichment if properly raised and evidenced.

Ratio vs. Obiter: Ratio - time limitation under Section 11B is mandatory and unjust enrichment is a valid statutory consideration in refund adjudication; Obiter - procedural limitation on raising these grounds at appellate/Tribunal stage where absent from SCN/Original order (principle of fair notice).

Conclusion: Where Section 11B time-bar or unjust enrichment is properly pleaded in the SCN/Order-in-Original, they operate to bar or reduce refund; but if the revenue first raises them at appellate stage without prior notice in SCN/Order-in-Original, such belated invocation is procedurally impermissible and cannot defeat a bona fide refund claim based on otherwise established point-of-taxation principles. The Tribunal remitted for consequential action consistent with this approach.

Overall Disposition

The Tribunal majority concluded that SBC/KKC charged on running invoices merely adjusting advances paid and already taxed on receipt were not chargeable and the recipient was entitled to refund; procedural principles precluded sustaining the revenue's non-revision/ST-3 ground when it was not raised in the SCN/Order-in-Original; limitation and unjust-enrichment defences remain available where properly raised and evidenced but cannot be invoked belatedly to defeat the claim without prior notice. The technical member's competing view (consistent with Supreme Court precedent on self-assessment and refund adjudication) that refund cannot be entertained absent revision/reopening of provider's returns was noted and referred, producing the majority outcome described above.
