Facts of the Case

The petitioners were industrial units engaged in diverse manufacturing activities in Assam and the North-Eastern Region. Many had established or expanded their industrial units in reliance upon the fiscal incentives announced under NEIIPP, 2007 and the corresponding area-based Central Excise exemption framework, particularly Notification No. 20/2007-CE dated 25.04.2007.

Under the pre-GST regime, eligible industrial units claimed exemption/refund of Central Excise duty for the prescribed period, subject to the terms and conditions of the relevant policy and notifications. According to the petitioners, substantial investments had been made on the strength of the Government’s representation that the fiscal benefits would remain available for the promised eligibility period.

With the introduction of GST from 01.07.2017, the earlier indirect tax regime underwent a fundamental statutory restructuring. The Central Excise exemption notifications relevant to the petitioners ceased to operate in their previous form, and the Central Government introduced the Scheme of Budgetary Support under GST Regime dated 05.10.2017 for eligible units located in specified States.

The petitioners challenged the reduction in the effective fiscal benefit under the Budgetary Support Scheme. Their principal grievance was that the new scheme did not preserve the full monetary equivalent of the earlier exemption benefit for the unexpired portion of their original eligibility period. They sought continuation of the promised benefit, substantially contending that the Union could not resile from its earlier representation after industries had altered their position and invested substantial capital.

Issues Involved

The principal questions before the Court were:

  1. Whether industrial units that had enjoyed or were eligible for area-based Central Excise exemption under NEIIPP, 2007 and Notification No. 20/2007-CE possessed a vested or enforceable right to continuation of an equivalent benefit after introduction of GST.
  2. Whether the Scheme of Budgetary Support dated 05.10.2017 unlawfully curtailed the incentives earlier promised to eligible industrial units.
  3. Whether the Union of India was bound by the doctrine of promissory estoppel and could be compelled to maintain the earlier level of exemption or refund for the residual eligibility period.
  4. Whether the petitioners had a legitimate expectation that the promised fiscal incentives would continue notwithstanding the replacement of the earlier tax regime by GST.
  5. Whether the proviso to Section 174(2)(c) of the Central Goods and Services Tax Act, 2017 prevented continuation of a tax exemption granted as an investment incentive once the underlying exemption notification had been rescinded.
  6. Whether a writ of mandamus could be issued requiring the Union Government to grant 100% refund or equivalent reimbursement of CGST for the remaining period of the earlier incentive entitlement.

Petitioners’ Arguments

The petitioners contended that NEIIPP, 2007 and Notification No. 20/2007-CE constituted clear governmental representations intended to attract industrial investment into the North-Eastern Region. Acting upon those representations, the industrial units had established new units or undertaken substantial expansion and had thereby altered their position irreversibly.

It was argued that the Government could not subsequently reduce the promised incentive during the unexpired eligibility period. According to the petitioners, the doctrine of promissory estoppel prevented the State from withdrawing or materially curtailing the benefit after investments had been induced by the Government’s promise.

The petitioners specifically argued that the Budgetary Support Scheme dated 05.10.2017 curtailed the benefits available under NEIIPP, 2007 and Notification No. 20/2007-CE and was therefore inconsistent with the Government’s earlier assurance. They relied upon the proposition that promissory estoppel may operate even in relation to governmental fiscal representations and statutory notifications.

They further contended that discussions in GST Council meetings reflected governmental awareness that premature withdrawal of time-bound area-based exemptions could invite challenges based on promissory estoppel. According to them, those discussions also indicated that direct budgetary reimbursement was considered a possible mechanism for protecting the residual benefits.

The petitioners maintained that the Government could resile from its promise only upon demonstrating a compelling or supervening public interest. Their case was that no adequate supervening public interest had been established to justify the alleged curtailment of the promised incentive.

Reliance was placed on the development of the doctrines of promissory estoppel and legitimate expectation, including State of Jharkhand vs Brahmaputra Metallics Ltd., to contend that governmental representations affecting commercial investment and business planning must be held to standards of fairness, consistency and accountability. The petitioners’ detailed plea that the Budgetary Support Scheme violated the earlier promise under NEIIPP, 2007 is expressly reflected in the judgment.

Respondents’ Arguments

The Union of India and GST authorities opposed the petitions and contended that promissory estoppel could not be invoked to defeat or override an express statutory provision.

The respondents placed particular reliance on the proviso to Section 174(2)(c) of the CGST Act, 2017. Their argument was that Parliament had expressly provided that a tax exemption granted as an investment incentive through a notification would not continue as a privilege where the relevant notification had been rescinded.

It was submitted that the earlier Central Excise exemption notification had been rescinded pursuant to the transition to GST. Therefore, in the absence of a successful challenge to the rescission itself or to the constitutional validity of the proviso to Section 174(2)(c), the petitioners could not enforce continuation of the former exemption by invoking promissory estoppel.

The respondents also contended that there was no statutory duty requiring the Union of India to refund 100% of CGST. Consequently, a writ of mandamus compelling full reimbursement could not be issued.

Reliance was placed upon judicial authority concerning the changed statutory regime, including Hero Motocorp Ltd. vs Union of India, and upon the principle that there can be no estoppel against the legislature in the exercise of legislative functions. The respondents’ Section 174(2)(c) argument and their reliance on Hero Motocorp are specifically recorded in the judgment.

Court Order / Findings

The Gauhati High Court considered the extensive submissions on promissory estoppel, legitimate expectation, fiscal incentives and the statutory consequences of the GST transition.

A decisive consideration was the legal effect of the proviso to Section 174(2)(c) of the CGST Act and the binding principles governing withdrawal of exemption notifications upon introduction of GST.

The Court took note of the governing principle that there can be no promissory estoppel against the legislature in the exercise of legislative functions. It considered that the withdrawal of exemption notifications pursuant to the statutory mandate of Section 174(2)(c) could not be neutralised merely by invoking promissory estoppel.

The Court further recognised that the proviso to Section 174(2)(c) specifically contemplates that a tax exemption granted as an incentive against investment through a notification does not continue as a privilege once the relevant notification is rescinded. An interpretation compelling automatic continuation of the earlier exemption benefit would render the statutory proviso ineffective.

The Court also considered the principle that a change in policy arising from public interest or from a fundamental change in the statutory tax regime—such as introduction of GST—could not automatically bind the Union to continue the precise fiscal representation made under the former tax system.

Most importantly, the Court applied the binding legal position that, in the absence of a statutory duty requiring the Union to grant 100% refund of CGST, a writ of mandamus directing such full refund could not be issued. The judgment records that the Supreme Court had rejected the estoppel claim in the relevant statutory setting, treated Section 174(2)(c) as decisive, and held that no mandamus for 100% CGST refund could issue without a corresponding statutory duty.

Accordingly, the petitioners could not secure continuation of the full pre-GST exemption or a 100% equivalent GST refund merely on the basis of promissory estoppel or legitimate expectation.

Important Clarification

This judgment does not mean that governmental promises, industrial policies or fiscal representations are universally immune from judicial review. The doctrines of promissory estoppel and legitimate expectation remain important public-law principles.

The crucial distinction is that these doctrines cannot ordinarily be applied so as to override an express legislative mandate. In the present context, Section 174(2)(c) of the CGST Act and the rescission of the former exemption notifications materially affected the petitioners’ claim.

The judgment also discusses the broader and distinct nature of legitimate expectation. It notes the legal development that legitimate expectation is not necessarily synonymous with promissory estoppel and may arise from governmental conduct, previous practice or past representation. Nevertheless, such public-law doctrines could not, on the facts and governing statutory framework, create a statutory obligation upon the Union to provide 100% CGST reimbursement.
