The Supreme Court has upheld the authority of the State Government to withdraw or modify exemptions granted under taxing statutes, while simultaneously directing that such withdrawal must operate only after a reasonable notice period of one year.
The bench of Justice Pamidighantam Sri Narasimha and Justice Alok Aradhe has clarified that exemptions under fiscal statutes are concessions rather than enforceable rights. The State retains the power to withdraw or modify exemptions in public interest under the same statutory provision. Beneficiaries of such exemptions do not have a vested right to demand their indefinite continuation. Doctrines like promissory estoppel and legitimate expectation cannot prevent the State from changing policy, especially where larger public interest—such as revenue augmentation—is involved.
The judgment came in a batch of appeals filed by the State of Maharashtra challenging earlier decisions of the High Court, which had struck down notifications issued under Section 5A of the Bombay Electricity Duty Act, 1958. These notifications had effectively withdrawn or curtailed electricity duty exemptions previously granted to industries operating captive power plants.
The dispute traces back to policy measures introduced by the State Government in the 1990s to encourage industries to generate their own electricity through captive power plants. To promote such self-sufficiency and reduce pressure on public power supply, the State granted exemptions from electricity duty beginning in 1994.
However, in 2000 and 2001, the State issued fresh notifications revising and partially withdrawing these exemptions. While full exemption was restored in 2005, the intervening period—from April 2000 to April 2005—remained contentious, with industries being subjected to electricity duty.
Industrial units challenged these notifications before the High Court, which ruled in their favour, holding the withdrawal to be arbitrary, discriminatory, and lacking justification.
The central question before the Supreme Court was whether the State, having granted a tax exemption, could later withdraw or modify it using the same statutory power, and whether such withdrawal violated principles like promissory estoppel and legitimate expectation.
The Court emphasized that decisions relating to taxation and exemptions fall within the domain of economic policy, where judicial interference is limited unless the action is manifestly arbitrary or discriminatory.
The Court noted that electricity duty is a crucial source of revenue and that the Government must retain flexibility to adjust fiscal policies based on changing economic conditions, including budgetary constraints.
The Court found that the withdrawal of exemption was a policy decision aimed at augmenting public revenue and could not be termed arbitrary or unreasonable.
However, the Court also recognized the practical difficulties faced by industries that had structured their operations based on earlier exemptions. It held that sudden withdrawal without adequate notice could cause undue hardship.
Invoking principles of fairness, the Court ruled that the impugned notifications would take effect only after one year from their respective dates. This transition period would allow industries to reorganize their financial and operational arrangements.
The Supreme Court set aside the High Court’s judgments and upheld the validity of the State’s notifications, subject to the one-year deferred implementation. The appeals were accordingly allowed, with no order as to costs.
