Facts of the Case

A batch of industrial units situated in Assam and the North Eastern Region, led by Star Cement Ltd., approached the Gauhati High Court challenging the extent of benefits available under the Scheme of Budgetary Support dated 05.10.2017 introduced after implementation of GST.

The petitioners were engaged in diverse manufacturing activities, including cement, clinker, calcined petroleum coke, plywood, steel products, plastic products, electrical equipment, packaged drinking water and other goods. Several petitioners claimed eligibility for fiscal incentives under the North East Industrial and Investment Promotion Policy, 2007 (NEIIPP, 2007) and the corresponding Notification No. 20/2007-CE dated 25.04.2007, which provided area-based Central Excise benefits for eligible industrial units.

According to the petitioners, relying upon the representations and incentives contained in NEIIPP, 2007 and the excise exemption framework, they had established new units or undertaken substantial expansion and made significant investments.

With the introduction of GST from 01.07.2017, the earlier indirect tax structure underwent fundamental statutory changes. Thereafter, the Government framed the Scheme of Budgetary Support dated 05.10.2017 for eligible units for the residual period of their earlier incentive entitlement.

Under the Scheme, budgetary support was linked to specified portions of tax paid through the cash ledger after utilisation of input tax credit, broadly including:

  • 58% of Central Tax paid through debit in the cash ledger in terms of Section 49(1) of the CGST Act, 2017, after utilisation of eligible input tax credit; and
  • 29% of Integrated Tax paid through debit in the cash ledger, with reference to the IGST framework and Section 20 of the IGST Act, 2017.

The petitioners contended that this mechanism materially curtailed the benefit of the full exemption allegedly promised under NEIIPP, 2007 and Notification No. 20/2007-CE. The primary challenge was therefore directed against the Budgetary Support Scheme insofar as it restricted reimbursement to the Central Government’s specified share of CGST/IGST rather than preserving the earlier benefit in full.

Issues Involved

The principal issues before the Gauhati High Court were:

  1. Whether the Scheme of Budgetary Support dated 05.10.2017 unlawfully curtailed the fiscal benefits promised to eligible industrial units under NEIIPP, 2007 and Notification No. 20/2007-CE dated 25.04.2007.
  2. Whether the Union of India was bound by the doctrine of promissory estoppel to continue the earlier level of Central Excise exemption for the entire promised period despite the introduction of GST.
  3. Whether industrial units that had altered their position and made substantial investments relying upon NEIIPP, 2007 acquired an enforceable right to equivalent fiscal benefits after the statutory transition to GST.
  4. Whether the Budgetary Support Scheme was arbitrary, discriminatory or violative of Article 14 of the Constitution of India.
  5. Whether the doctrine of legitimate expectation required continuation of the full economic value of the earlier exemption.
  6. Whether the rescission of the earlier Central Excise exemption framework upon introduction of GST could be challenged on the basis of vested or accrued rights.
  7. Whether the Central Government could restrict budgetary support to its own retained share of CGST/IGST under the post-GST constitutional and statutory framework.

Petitioners’ Arguments

The petitioners contended that the Government had made a clear and unequivocal promise under NEIIPP, 2007 to provide fiscal incentives, including Central Excise benefits, for a fixed period.

They argued that, acting upon this promise, eligible units had:

  • established industries in the North Eastern Region;
  • made substantial capital investments;
  • undertaken expansion of existing units;
  • altered their economic and commercial position irreversibly; and
  • generated industrial activity and employment in the region.

Accordingly, the Government could not resile from its representation before expiry of the promised incentive period.

The petitioners submitted that the Budgetary Support Scheme dated 05.10.2017 did not preserve the full benefit earlier available. Instead, it restricted support to specified portions of Central Tax and Integrated Tax paid through the cash ledger, thereby substantially reducing the promised fiscal incentive.

They relied heavily upon the doctrine of promissory estoppel, arguing that the Government was bound to honour its promise because the industrial units had materially altered their position on the strength of the incentive policy.

It was further argued that:

  • NEIIPP, 2007 had not been validly withdrawn insofar as the underlying governmental promise was concerned;
  • introduction of GST could not by itself destroy rights and privileges acquired under the earlier industrial policy;
  • the Budgetary Support Scheme itself demonstrated governmental recognition of the continuing obligation towards eligible units;
  • once support was introduced to fulfil the earlier assurance, it could not be framed in a manner that substantially curtailed the promised benefit;
  • no overriding or supervening public interest had been established to justify departure from the earlier promise; and
  • the impugned action violated Article 14, substantive legitimate expectation and the requirement of non-arbitrariness in State action.

The petitioners also referred to GST Council deliberations to contend that the legal risk of prematurely withdrawing time-bound area-based exemptions had itself been recognised and that equivalent support through the budgetary route was contemplated.

Respondents’ Arguments

The Union of India and GST authorities opposed the writ petitions.

The respondents submitted that the pre-GST taxation structure and the post-GST regime were fundamentally different. Under the earlier system, multiple Central and State indirect taxes operated separately, whereas GST introduced a constitutionally restructured destination-based tax system from 01.07.2017.

It was argued that:

  • the earlier Central Excise exemption operated within the statutory framework of the Central Excise Act;
  • the legal basis of the earlier exemption could not automatically continue after the relevant tax structure was subsumed or altered under GST;
  • the petitioners had no vested right to insist that an exemption under the old tax regime must continue identically under a new statutory regime;
  • exemption notifications are inherently subject to statutory power of modification or rescission;
  • the Government was competent to frame a fresh Budgetary Support Scheme suited to the post-GST fiscal structure;
  • budgetary support could legitimately be linked to the Central Government’s share of tax;
  • the doctrine of promissory estoppel could not compel the Government to act contrary to law or preserve an obsolete tax mechanism after legislative restructuring; and
  • fiscal and economic policy decisions are entitled to substantial judicial deference.

The respondents specifically emphasised the fundamental transformation brought about by GST and defended the Budgetary Support Scheme as a policy response designed for eligible units during the residual incentive period under the changed tax structure.

Court Order / Findings

The Gauhati High Court examined the challenge in the context of the transition from the Central Excise regime to GST, the scope of NEIIPP, 2007, the nature of exemption notifications, the Budgetary Support Scheme and the doctrines of promissory estoppel and legitimate expectation.

The Court’s reasoning, in substance, recognised the important distinction between:

  • a policy representation encouraging industrial investment; and
  • an immutable legal right to continuation of a particular tax exemption mechanism despite a subsequent statutory and constitutional restructuring of the tax regime.

The Court considered that the earlier exemption operated under the Central Excise statutory framework, whereas GST introduced a materially different tax regime. The doctrine of promissory estoppel could not be applied so as to compel continuation of the old exemption structure contrary to the changed statutory framework.

The Court did not accept the proposition that eligible units possessed an indefeasible right to insist upon full continuation of the earlier Central Excise exemption in equivalent form under GST merely because investments had been made under NEIIPP, 2007.

The Budgetary Support Scheme was treated as a policy measure framed in response to the transition to GST and designed to provide support for the residual eligibility period under the new fiscal structure. The mere fact that the quantum or mechanism of support differed from the former Central Excise exemption did not, by itself, establish that the Scheme was legally invalid.

Accordingly, the challenge founded on promissory estoppel, legitimate expectation and Article 14 did not justify judicial rewriting of the Budgetary Support Scheme to compel reimbursement equivalent to the entire former exemption.

Result: The petitioners were not held entitled to compel continuation of the full pre-GST Central Excise exemption benefit under the GST regime by invoking promissory estoppel. The challenge to the limited structure of the Budgetary Support Scheme did not succeed on that basis.

Important Clarification / Legal Principle Established

This judgment is important for understanding the legal treatment of pre-GST area-based tax incentives after implementation of GST.

The key clarification is that a fiscal incentive granted under an earlier statutory tax regime does not necessarily create an immutable right to an identical tax benefit after the underlying tax structure itself has been fundamentally replaced.

The judgment distinguishes between:

  • continuation of an industrial promotion policy objective; and
  • continuation of a specific statutory tax exemption in precisely the same form.

It further clarifies that promissory estoppel cannot automatically be used to preserve an old tax exemption mechanism after legislative restructuring, particularly where the Government has adopted a separate budgetary support mechanism under the new regime.

At the same time, the case reflects the broader principle that claims of promissory estoppel against the Government depend upon the nature of the representation, statutory authority, public interest, alteration of position and the legal framework existing at the relevant time.
