Processes deemed manufacturing; services not taxable under Section 66D; refund allowed, unjust enrichment remanded for further inquiry

CESTAT CHD (AT) held the processes undertaken by the appellants amount to manufacture and therefore were not exigible to service tax under Section 66D of the Finance Act, 1994. The appellants are entitled to seek refund of the service tax paid, but the question of unjust enrichment was left undecided; the matter is remanded to the Commissioner (Appeals) for determination of whether the tax burden was passed on, having regard to records and the chartered accountant's certificate. Appeal partially allowed by way of remand.

ISSUES PRESENTED AND CONSIDERED

1. Whether the processes performed on semi-finished/storage batteries (electrolytic filling, jar-formation, charging, testing, drying, sealing, terminal work, labeling and packing) amount to "manufacture" within the meaning of Section 2(f) of the Central Excise law and Note 6 to Section XVI of the Tariff Act, so as to fall within the negative list (Section 66D) and be not exigible to service tax.

2. Whether the appellants are entitled to refund of service tax paid, having paid under a mistaken view that the activity was not manufacture - including whether the refund is maintainable where the self-assessment was not appealed against and whether the bar of unjust enrichment (i.e., burden to prove tax incidence was not passed on) precludes refund.

3. Whether the Revenue could raise for the first time at appellate hearing the contention that the refund claim is not maintainable because the self-assessment was not assailed earlier, when that contention was not raised in the show cause notice or in earlier orders.

ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Whether the processes constitute "manufacture"

Legal framework: Section 2(f) definition of "manufacture" (including processes incidental or ancillary) and Note 6 to Section XVI of the Central Excise Tariff Act: conversion of an article incomplete/unfinished but having the essential character of the complete article into a complete/article shall amount to manufacture; Section 66D (Finance Act, 1994) - negative list excluding processes amounting to manufacture from service tax.

Precedent treatment: The Tribunal relied on a Principal Bench decision (referred to as Exide Industries) which held that electrolytic filling, jar formation and allied processes on semi-finished batteries convert them into marketable complete batteries and therefore amount to manufacture; that decision has been accepted by the department in that context and was treated as directly analogous.

Interpretation and reasoning: The Tribunal examined the exact processes described - receipt of semi-finished/unformed batteries, electrolytic filling, jar formation, charging, leakage testing, drying/washing, sealing/vent plug tightening, terminal work, labeling/barcode/jelly pasting, quality control and final packing - and found them identical in substance to the processes in the Exide decision. Applying Note 6 of Section XVI, the conversion of semi-finished batteries having essential character of finished batteries into marketable complete batteries satisfies the statutory test of manufacture. The Tribunal also noted that Section 2(f) includes incidental or ancillary processes and that the process list in Chapter/Section notes is not a cumulative requirement for deeming "manufacture".

Ratio vs. Obiter: Ratio - processes of electrolytic filling, jar formation, charging and allied finishing/packing on semi-finished batteries amount to manufacture under Note 6 to Section XVI and Section 2(f); hence such processes fall within the negative list and are not exigible to service tax. Observational/ancillary remarks about related jurisprudence (e.g., interpretation of Section 2(f) text and CBIC clarification) are obiter to the extent they do not change the holding.

Conclusion: The Tribunal held (ratio) that the appellant's processes amount to manufacture; therefore, those activities are not exigible to service tax under Section 66D, and the appellants were not required to pay service tax on those processes.

Issue 2 - Entitlement to refund and unjust enrichment

Legal framework: Principles of refund where tax was paid under mistake of law; statutory bar of unjust enrichment under Central Excise provisions (Section 11B and allied jurisprudence) placing burden on claimant to show tax incidence was not passed on; requirement that refund be admissible on other normative grounds.

Precedent treatment: The Revenue relied on decisions (including ITC, BT (India), Kalyan Toll) holding that a challenge to self-assessment or continuity/finality of assessment can affect refund maintainability; appellants relied on decisions allowing refund where payment was under mistake and on authorities holding that mere mention of tax in invoice does not conclusively prove passage of incidence (multiple cited High Court/Tribunal authorities). The Tribunal noted conflict/interaction among precedent lines and observed that some higher court decisions in excise/customs context have affected the larger-bench approach, but distinguished the present facts on procedural grounds (see Issue 3).

Interpretation and reasoning: Having concluded the activity was not exigible to service tax, the Tribunal recognized that refund entitlement also requires adjudication on whether the appellants passed on the tax to their principal (unjust enrichment). The Tribunal observed that the Commissioner (Appeals) had confined his findings to the manufacture issue and had not adjudicated unjust enrichment; hence the record lacked a determination on whether the appellants bore the incidence. The appellants produced a Chartered Accountant certificate asserting non-recovery from the principal and argued that invoices showing tax separately did not prove passage of incidence in view of corroborative authorities. The Revenue challenged the certificate's sufficiency and relied on the invoices and precedent to assert a rebuttable presumption that incidence had passed on.

Ratio vs. Obiter: Ratio - entitlement to refund cannot be finally determined without adjudication on unjust enrichment; where the lower order did not decide unjust enrichment, appellate forum should not decide it in absence of record/ findings and instead remit for determination. Observations about the sufficiency of specific invoices and certificates and the competing precedents on burden of proof are obiter dicta relative to the remand decision.

Conclusion: The Tribunal did not finally decide refund admissibility; it remanded the matter to the Commissioner (Appeals) with directions to independently examine and decide admissibility of refund on all norms including unjust enrichment, having regard to records, submissions and the Chartered Accountant certificate.

Issue 3 - Raise of maintainability/self-assessment point at appellate stage and procedural bars

Legal framework: Principle that an order must stand or fall on reasons contained therein (Mohinder Singh Gill principle) and that parties cannot be taken by surprise by introduction of new grounds at appellate stage; duties of Revenue to plead grounds in show cause notice/orders or raise them in cross-appeal; doctrine of hearing and natural justice.

Precedent treatment: The Tribunal referred to Principal Bench and other decisions (Ingram Micro, Umed Club, ACME Cleantech) applying Mohinder Singh Gill to hold that fresh reasons cannot be advanced at appellate stage if not recorded in earlier orders; it noted contrary authorities (ITC, BT (India), Kalyan Toll) which decline refund where self-assessment remains unchallenged, and observed that higher court treatment has affected the applicability of some Larger Bench pronouncements.

Interpretation and reasoning: The Tribunal found the Revenue first raised the maintainability/self-assessment objection belatedly at the appellate hearing and did not include it in show cause notice, original order or Commissioner (Appeals) order; the Tribunal held that raising such a ground for the first time at final hearing is impermissible and would violate the principle that an order's validity is judged on its recorded reasons. Consequently, the Tribunal declined to entertain the belated maintainability plea for the purpose of disposing the present appeal on that ground.

Ratio vs. Obiter: Ratio - Revenue cannot be permitted to advance a new legal plea at appellate hearing that was not raised in earlier proceedings or in cross-appeal; an order must be tested by the reasons recorded therein and not by after-the-fact justifications. Observations on the state of precedent conflict are obiter to the extent they do not alter the remand direction.

Conclusion: The maintainability/self-assessment contention raised belatedly by the Revenue was not entertained; the Tribunal remanded the case for the Commissioner (Appeals) to decide unjust enrichment and refund admissibility consistent with the recorded reasons and the parties' pleadings.

Disposition and consequential direction (linked to above issues)

The Tribunal allowed the appeal partially by holding the processes constitute manufacture (Issue 1). Because the Commissioner (Appeals) had not decided unjust enrichment, the Tribunal remanded the matter to the Commissioner (Appeals) to give independent findings on admissibility of refund, including unjust enrichment and any other relevant norms, after examining records and submissions (Issues 2-3). The Tribunal did not finally adjudicate refund entitlement.
