M/S. Kothari Industrial Corp. Ltd vs Tamilnadu Electricity Board & Anr

The Supreme Court addressed the applicability of the principles of promissory estoppel and legitimate expectation in the context of tariff concessions under the Tamil Nadu Revision of Tariff Rates on Supply of Electrical Energy Act, 1978. The Court noted that the respondents amended the tariff conditions, which the appellants challenged based on their reliance on previous concessions. The Court held that due to differing opinions in prior judgments, the matter should be referred to a larger bench for clarification on these legal principles.
