Case Note & Summary
The dispute arose from appeals concerning the applicability of promissory estoppel in relation to sales tax exemptions under the Haryana General Sales Tax Act, 1973. The appellants, Mahabir Vegetable Oils Pvt. Ltd. and Bharat Rasayan Ltd., challenged the inclusion of solvent extraction plants in a negative list that disqualified them from sales tax benefits. The State of Haryana had previously announced an industrial policy promising exemptions for industries set up in backward areas, which the appellants relied upon when making significant investments. The High Court dismissed the appellants' writ petitions, asserting that the State's power to grant exemptions was a legislative function that could be modified. The appellants contended that they had made substantial investments based on the existing rules and that the retrospective amendment was arbitrary and unjust. The Supreme Court analyzed the principles of promissory estoppel, referencing previous judgments that established the doctrine's applicability in legislative contexts. The Court concluded that the State could not withdraw the promised benefits without a valid public interest justification, especially after the appellants had acted on the representations made by the State. The Court set aside the High Court's judgment, allowing the appeals and remitting the matter to the Director of Industries for reconsideration, affirming that the amendments could not have retrospective effect prior to the enactment of relevant provisions in the Act.
