Retroactive Rule 6 CCR (2016) not applicable; CENVAT credit reversal for unsold units unlawful, refund ordered under Section 142(3) CGST

CESTAT allowed the appeal, holding the reversal of CENVAT credit for unsold units following issue of completion certificate was not legally permissible. The panel found the 2016 amendment to Rule 6 CCR prospective and could not be invoked retroactively; credit entitlement is determined on the date of availment. As the reversal was erroneous, the appellant is entitled to refund of the amounts wrongly reversed. Section 142(3) of the CGST Act precludes denial on time-bar grounds under Section 11B and limits refusal to cases of unjust enrichment; impugned orders set aside.

ISSUES PRESENTED AND CONSIDERED

1. Whether CENVAT credit availed on input services and capital goods prior to issuance of completion certificate must be reversed under Rule 6 of the CENVAT Credit Rules, 2004 when portions of the construction activity become non-taxable on receipt of completion certificate.

2. Whether the insertion of Explanation-3 to Rule 6 by Notification No.13/2016 (stating that "exempted service" includes an activity which is not a "service" under Section 65B(44)) operates retrospectively so as to require reversal of credits availed before its effective date.

3. Whether an amount voluntarily or under protest reversed by an assessee (in respect of credits later held not liable for reversal) is refundable to the assessee.

4. Whether a refund claim of CENVAT credit (filed post-transition to GST) is time-barred under Section 11B of the Central Excise Act, notwithstanding Section 142(3) of the CGST Act which governs refund of amounts paid under the existing law.

ISSUE-WISE DETAILED ANALYSIS

Issue 1: Reversal of CENVAT credit under Rule 6 when output service later becomes non-taxable on issuance of completion certificate

Legal framework: Rule 6 of the CENVAT Credit Rules, 2004 prescribes reversal/ payment where inputs or input services are used in making exempted or non-taxable output services; the mechanism provides for proportionate reversal or payment linked to exempted output. Rule 11(4) (and comparison with Rule 11(1)-(3) dealing with goods) is relevant in assessing specific provisions for service sector reversals.

Precedent treatment: The Tribunal and High Court decisions reasoned that CENVAT credit validly and legally availed on a date when the output activity was wholly dutiable constitutes a vested/indefeasible right; subsequent change rendering the output partly non-taxable does not automatically trigger reversal unless an express statutory provision applies retroactively. Higher Court precedents establishing indefeasibility of credit were relied on.

Interpretation and reasoning: The Court examined the temporal entitlement to credit - entitlement is to be assessed on the date of availment. Where input services were availed while the output was taxable, such credits become vested rights and are not extinguishable by later cessation or partial exemption of the output service absent express statutory provision. The adjudicatory approach that treats later non-taxable characterization as attracting reversal of past valid credits was rejected in light of the absence of a provision equivalent to Rule 11(1)-(3) for services and consistent precedents holding credit indefeasible.

Ratio vs. Obiter: Ratio - CENVAT / input service credits validly availed during a period when the output service was taxable are not liable to be reversed merely because a portion of the output becomes non-taxable later upon issuance of completion certificate, absent specific statutory provision to that effect. Observational/ supporting precedent citations are obiter to the extent they reinforce the legal principle.

Conclusion: No reversal of eligible CENVAT credit availed prior to the date when output services became non-taxable is required under Rule 6.

Issue 2: Prospective vs. retrospective operation of Explanation-3 to Rule 6 (Notification No.13/2016)

Legal framework: Explanation-3 to Rule 6 purportedly enlarges the definition of "exempted service" to include activities which are not "service" under Section 65B(44). Temporal operation of statutory amendments must be determined by construction and by impact on vested rights.

Precedent treatment: Tribunal and High Court authority considered identical amendment and held that the insertion created a deeming fiction applicable prospectively from its notified effective date (1.04.2016) and cannot be given retrospective effect to extinguish credits availed earlier. Supreme Court precedents on indefeasibility of credit and on non-retrospective impairment of vested rights were followed.

Interpretation and reasoning: The Court construed Explanation-3 as prospective: the deeming fiction may operate from its effective date but cannot be applied to annul vested credits already legally availed prior to that date. Applying Explanation-3 retrospectively would have the effect of taking away rights already crystallized, which requires express statutory language; such language is absent. The amendment therefore does not mandate reversal of credits availed before its operative date merely because an activity was later treated as an "exempted service".

Ratio vs. Obiter: Ratio - Explanation-3 must be applied prospectively and cannot be invoked to require reversal of credits legally availed before its effective date. Supporting observations on statutory construction and vested rights are explanatory/obiter to the extent they illustrate underlying principles.

Conclusion: Explanation-3 does not attract reversal of pre-effective-date credits; Rule 6, as amended, is not applicable retrospectively to call for reversal of past credits.

Issue 3: Refundability of amounts reversed under protest when reversal is subsequently held not legally required

Legal framework: Where reversal/payment has been made and later held to be legally impermissible, principles of restitution and statutory refund provisions apply; refunds of amounts paid under existing law are governed by the transitional provision in Section 142(3) of the CGST Act and related refund jurisprudence.

Precedent treatment: Tribunal and High Court decisions have held that amounts reversed under protest and subsequently found to be not exigible must be refunded; authoritative decisions recognizing the indefeasible nature of validly availed credit and entitlement to restitution were applied.

Interpretation and reasoning: Given the Court's conclusion that there was no legal requirement to reverse eligible past credits, sums reversed by the assessee (even under protest) were wrongly appropriated by the revenue and therefore are refundable. The refund obligation follows once it is held the reversal was erroneous; procedural forms of reversal or temporal position (reversal undertaken to avoid enforcement action) do not preclude restitution.

Ratio vs. Obiter: Ratio - Amounts reversed which are subsequently adjudged not payable must be refunded to the assessee. Ancillary comments on the character of protest and quantum calculations are obiter to the extent they explain application.

Conclusion: The appellant is entitled to refund of amounts reversed in respect of credits that were not legally liable to be reversed.

Issue 4: Applicability of time bar under Section 11B to refund claims of CENVAT credit post-transition, vis-à-vis Section 142(3) of the CGST Act

Legal framework: Section 11B of the Central Excise Act prescribes time limits and conditions for refund claims under the earlier law; Section 142(3) of the CGST Act preserves disposal of refund claims filed before, on or after the appointed day in accordance with the provisions of the existing law subject to specified provisos and subject to subsection (2) of Section 11B regarding unjust enrichment.

Precedent treatment: Transitional jurisprudence recognizes that Section 142(3) governs claims for refund of amounts paid under the existing law and that the bar in Section 11B(1) cannot be mechanically applied where Section 142(3) has an overriding effect, subject to unjust enrichment considerations.

Interpretation and reasoning: The Court held that refund claims of CENVAT credit falling under Section 142(3) are to be disposed of under existing law but the time limitation in Section 11B(1) cannot be imposed where Section 142(3) provides otherwise. The only ground for denial under Section 142(3) is unjust enrichment per subsection (2) of Section 11B. Therefore, a refund application filed under Section 142(3) is not time-barred by Section 11B(1) where the claim is governed by the transitional provision and unjust enrichment is not established.

Ratio vs. Obiter: Ratio - Time limitation under Section 11B(1) does not automatically bar refund claims filed under Section 142(3) of the CGST Act; denial is permissible only on unjust enrichment grounds provided by the statute.

Conclusion: The refund claim was not time-barred; refund must be allowed subject only to unjust enrichment considerations, which were not established by the revenue on the facts.

Final Disposition (Legal Conclusion)

The Court concluded that (i) credits validly availed while the output service was taxable are indefeasible and not subject to reversal under Rule 6 by reason of later issuance of completion certificate; (ii) Explanation-3 to Rule 6 must be read prospectively and cannot retrospectively extinguish vested credit rights; (iii) amounts reversed but later determined not to be payable are refundable; and (iv) refund claims filed under Section 142(3) are not time-barred by Section 11B(1) and may be denied only on unjust enrichment grounds. Consequently, the impugned orders upholding reversal and rejecting refund were set aside and the appeals allowed.
