In a significant ruling balancing government policy and industrial interests, the Supreme Court clarified that states can withdraw tax exemptions granted to industries but not abruptly. The Court granted relief to captive power producers by allowing a transition period before the withdrawal takes effect.
Background of the Case
The case, State of Maharashtra vs Reliance Industries Ltd. & Ors., revolved around electricity duty exemptions granted to industries generating their own power through captive plants.
The Maharashtra government had initially provided exemptions under the Bombay Electricity Duty Act, 1958 to encourage industries to produce their own electricity. Over time, several notifications were issued first granting exemptions, and later modifying or withdrawing them between 2000 and 2001.

Industries challenged these changes before the High Court, arguing that they had made substantial investments relying on the earlier exemptions. The High Court struck down the State’s notifications, calling them arbitrary.
Hearing the appeals, the Supreme Court examined whether the State could legally withdraw such exemptions.
The bench observed that an exemption is not a permanent right but a concession granted under law.
“The recipient of a concession has no legally enforceable right to its continuation indefinitely,” the Court noted.
It further clarified that the State retains the authority to modify or withdraw exemptions if required in public interest, particularly for fiscal reasons such as revenue needs.

Rejecting the argument of unfairness, the Court said that industries should be aware that such benefits can be altered. It also held that doctrines like promissory estoppel (a promise that cannot be withdrawn) and legitimate expectation would not apply when the State acts in public interest.
At the same time, the bench emphasized that government decisions must still meet standards of fairness and reasonableness under Article 14 of the Constitution.
A crucial concern before the Court was the sudden withdrawal of exemptions.
The judges acknowledged that industries had structured their operations and finances based on the earlier policy. Abrupt withdrawal, without any adjustment period, could impose an immediate financial burden.
“The principles of fair play demand that such withdrawal should not operate in a manner that causes undue hardship,” the Court observed.

The Court stressed that while policy changes are allowed, they should not disrupt businesses overnight without giving them time to adapt.
Setting aside the High Court’s ruling, the Supreme Court upheld the State’s power to withdraw or modify electricity duty exemptions.
However, it introduced a key safeguard:
The notifications dated April 1, 2000 and April 4, 2001 will take effect only after a one-year notice period from their respective dates.
This means industries are entitled to a reasonable transition window to reorganize their financial and operational arrangements.
The Court allowed the appeals filed by the State of Maharashtra and disposed of the matter without any order on costs.
