Eicher Motors v. Union of India: when input credit becomes a vested right

The facts in brief

Eicher Motors Ltd, a manufacturer of tractors, and a clutch of motor-vehicle manufacturers had been operating under the Modified Value Added Tax (MODVAT) scheme introduced into the Central Excise Rules 1944 in 1986. Rule 57A permitted a manufacturer of specified final products to take credit of the central excise duty paid on specified inputs used in or in relation to the manufacture of those final products. The accrual trigger was structural: receipt of duty-paid inputs in the factory, declaration in the prescribed form, and entry in the RG-23A credit register. The credit so taken could then be utilised, under Rule 57F, to discharge duty on cleared final products. Substantial unutilised balances built up in the credit registers of tractor and motor-vehicle manufacturers through 1994-95 as a function of the duty-rate structure and the lag between input procurement and final-product clearance.

On 16 March 1995, by Notification 14/95-CE(NT), the Central Government inserted Rule 57-F(4-A) with effect from that very date. The text was peremptory: any credit of specified duty lying unutilised on 16 March 1995 with a manufacturer of tractors or motor vehicles "shall lapse and shall not be allowed to be utilised for payment of duty on any excisable goods". A narrow exception preserved credit attributable to inputs lying in stock or contained in finished goods in stock on that date. Outside that exception, the lapse operated by force of the rule itself — without notice, without enquiry, and without compensation.

The petitioners' position, distilled, was that the lapse was not a prospective recalibration of the MODVAT scheme but a retrospective confiscation of credit already accrued on inputs procured before 16 March 1995 with duty already paid into the exchequer. Commercial decisions on input procurement, capital deployment and pricing had been organised on the legitimate expectation that the credit would offset future excise duty. Rule 57-F(4-A), in extinguishing the credit overnight, defeated that expectation in respect of property already vested. The Government's response was that the MODVAT scheme was a creature of subordinate legislation; the same rule-making power that conferred the credit could withdraw it; the credit was a concession, not a right; and Rule 57-F(4-A) was a measured fiscal correction accompanying the liberalisation of utilisation provisions in the 1995-96 Budget. Eicher Motors and the co-petitioners invoked Article 32 directly.

The constitutional question

The question presented was narrow but consequential. Did the rule-making power conferred by s.37 of the Central Excises and Salt Act 1944 extend to the retrospective extinction of MODVAT credit balances that had accrued under Rule 57A before the date of the impugned notification? Or did the accrued credit, once properly taken, occupy a position of vested entitlement that the rule-maker could not displace without express statutory authorisation?

A second strand was whether Rule 57-F(4-A) — even if within the rule-making power — was independently arbitrary under Article 14, and whether it violated Article 19(1)(g) by disrupting the petitioners' organised commercial expectations. A third strand, advanced but not decisively engaged, was whether MODVAT credit constituted "property" within Article 300A — a question the Court did not need to resolve to dispose of the petitions, and which would be developed in Dai Ichi Karkaria later the same year and through the ALD Automotive line two decades on.

What the Court held

Rajendra Babu J, writing for himself, Bharucha J and Venkataswami J, struck down Rule 57-F(4-A) to the extent it operated on credit balances accrued before 16 March 1995. The reasoning was structural.

The MODVAT scheme under Rule 57A operates on a defined trigger. Receipt of inputs in the factory, declaration in the prescribed form, and entry in the credit register together complete the assessee's entitlement. Once these statutory conditions are satisfied, the credit ceases to be inchoate and becomes vested. It represents a right accrued or acquired by the assessee under the existing law. The rule-making power conferred by s.37 of the Central Excises and Salt Act 1944, broad as it is, does not on its face extend to the retrospective extinction of such accrued rights. Subordinate legislation that purports to extinguish vested rights without express legislative backing operates beyond the rule-making power and is therefore ultra vires.

The bench went further on the Article 14 plane. Rule 57-F(4-A) was characterised as arbitrary and unreasonable — framed without due application of mind to the facts of MODVAT operation, resting on premises that were either non-existent or patently erroneous. What the rule-making power permits is fixing of a reasonable time within which the manufacturer must enforce the credit, not its outright extinction. The petitioners had organised their commercial affairs on the legitimate expectation that the credit would offset future excise duty; abrupt extinction disrupted that organisation in a manner the constitutional framework could not countenance.

The disposition was structural rather than merely declaratory. Rule 57-F(4-A) was held unconstitutional and unenforceable to the extent it operated on credit balances already accrued before 16 March 1995. The petitioners were entitled to utilise the impugned credit balances against duty on goods cleared after 16 March 1995. The Court did not need to engage with the Article 300A property argument because the ultra vires and arbitrariness grounds were sufficient to dispose of the petitions.

The doctrinal architecture

Eicher Motors accomplished three doctrinal moves simultaneously, each of which has been carried forward into the modern indirect-tax canon.

First, it established the credit-as-vested-right doctrine as the operative frame for indirect-tax input-credit jurisprudence. The credit is not a concession that the rule-maker bestows and may withdraw. It is a substantive entitlement that crystallises at the moment of statutory accrual and thereafter occupies a position of constitutional protection. The framing is conceptually adjacent to the property-rights doctrine but rests independently on the ultra vires and arbitrariness grounds.

Second, it established the limits-of-rule-making-power discipline for indirect-tax subordinate legislation. The rule-making power conferred by the parent statute may be broad, but it does not extend by implication to the retrospective extinction of rights that have accrued under the existing law. Express legislative backing is required for retrospective extinction; the rule-maker cannot achieve through subordinate legislation what the legislature has not authorised in the parent enactment.

Third, it established the legitimate-expectation strand that has run through indirect-tax jurisprudence ever since. The petitioners had organised input procurement, capital deployment and pricing on the legitimate expectation that the credit would offset future excise duty. That organisation is not a mere convenience that the rule-maker may disrupt; it is a substantive position that the constitutional framework protects against arbitrary retrospective displacement.

The judgment was followed and developed almost immediately by the same year's Collector of Central Excise v. Dai Ichi Karkaria Ltd (1999) 7 SCC 448, which restated the MODVAT credit as "indefeasible" once taken and supplied the conceptual vocabulary that loader through to CENVAT and onward to GST ITC. The Osram Surya (2003) 1 SCC 421 line then distinguished, holding that a time-limit for taking credit (the six-month proviso under Rule 57G) is procedural and valid, contrasted with extinction of credit already taken — Osram Surya and Eicher Motors together drawing the boundary between procedural-cure-window discipline and substantive-vested-right protection.

What the judgment did not decide

The bench did not rule on whether MODVAT credit constitutes "property" within Article 300A. The argument was advanced but the Court rested on ultra vires and arbitrariness grounds and did not need to develop the property-rights characterisation. The Article 300A strand was carried forward in subsequent litigation but has never been settled with the same categorical clarity as the ultra vires and arbitrariness grounds.

The bench did not address whether a prospective lapse provision — applicable only to credit accruing after the notification — would have been constitutionally valid. The judgment is confined to retrospective extinction. The implication, drawn out in later cases, is that a prospective lapse with a reasonable transition period and adequate notice would likely survive constitutional scrutiny, but the doctrinal architecture for prospective extinction remains under-developed.

The bench did not spell out the duration of "reasonable time" within which credit must be utilised before the rule-maker may attach a time-bar. The principle that a time-limit for utilisation is permissible was stated but not elaborated. Osram Surya later supplied a procedural-cure-window framework for the taking side; the utilisation side has been developed through the CENVAT and GST eras with less clarity.

The bench did not engage with the cash-refund question on closure of business — whether unutilised credit on permanent closure may be refunded in money rather than utilised against duty. That question travelled through the Slovak India line in the CESTAT and was engaged by the Supreme Court in the SAIL refund line in 2025.

Trajectory: from MODVAT to CENVAT to GST ITC

Eicher Motors is the foundational SC pronouncement on credit-as-vested-right and has shaped twenty-five years of indirect-tax jurisprudence. Dai Ichi Karkaria (1999) 7 SCC 448 re-affirmed and developed the doctrine within the same year. Osram Surya (2003) 1 SCC 421 calibrated the boundary between procedural time-bars on taking and substantive protection of taken credit. ALD Automotive Pvt Ltd v. CTO (2019) 13 SCC 225, a Tamil Nadu VAT decision, applied the same conceptual framework to the state-VAT architecture.

In the GST era the doctrine has been cited extensively in transitional-credit litigation. Siddharth Enterprises v. Nodal Officer (Guj HC 2019) and Brand Equity Treaties v. Union of India (Del HC 2020) drew on Eicher Motors in directing the re-opening of TRAN-1 windows. The Supreme Court in Union of India v. Filco Trade Centre Pvt Ltd (orders dated 22 July 2022 and 2 September 2022) opened the TRAN-1 portal for sixty plus thirty days — a softening that implicitly drew on the Eicher Motors equity. Safari Retreats Pvt Ltd v. Union of India (2024) on s.17(5)(d) ITC architecture rests doctrinally on the Eicher-line credit-as-right foundation, and the retrospective amendment of s.17(5)(d) by the Finance Act 2025 — substituting "plant or machinery" with "plant and machinery" with effect from 1 July 2017 — is itself now under HC challenge on Eicher-line vested-right grounds.

The 2026 constitutional ferment around s.16(2)(c) CGST has brought the Eicher Motors doctrine into renewed apex-level focus. The Supreme Court has issued notice in M/s Prime Metals v. Union of India on the constitutional validity of s.16(2)(c), which conditions ITC eligibility on the supplier having actually deposited tax — a structural denial of credit to a bona fide purchaser for an event outside the purchaser's control. The Gujarat High Court in Maruti Enterprise v. Union of India (1 May 2026) has held s.16(2)(c) constitutionally valid, framing ITC as a "statutory entitlement" subject to conditions rather than a vested right in the Eicher Motors sense. The tension between the Gujarat characterisation and the Eicher Motors doctrine is the doctrinal hinge on which the Prime Metals SLP will turn — and the apex-level resolution will determine whether the vested-right architecture Eicher Motors established for MODVAT credit translates intact into the GST ITC framework or is re-cast for the matching-system architecture of the GST era.
