Case Note & Summary
The dispute arose from appeals by the Tamil Nadu Electricity Board and the State of Tamil Nadu against a judgment of the Madras High Court regarding tariff concessions for High Tension Industries. The High Court had dismissed writ appeals challenging the validity of a notification that amended tariff concessions. The core issue was the interpretation of the term 'set up' in relation to the eligibility for tariff concessions under the Tamil Nadu Revision of Tariff Rates on Supply of Electrical Energy Act, 1978. The appellants contended that the term should be construed to mean that an industry must have obtained a service connection to qualify for concessions, while the respondents argued that the term should include industries that had commenced operations prior to the cut-off date. The Supreme Court analyzed the legislative intent behind the tariff concessions and the implications of the amendments made to the Schedule of the Act. It emphasized that the date of obtaining a service connection is crucial for determining eligibility for concessions. The court held that the amendments did not retroactively affect accrued rights and that the doctrine of promissory estoppel could apply in certain circumstances. Ultimately, the court upheld the interpretation that 'set up' means an industry must be ready to function to avail of the concessions, thereby affirming the High Court's decision on the matter.
