Case Note & Summary
The Supreme Court addressed appeals from the Tamil Nadu Electricity Board and the State of Tamil Nadu against a judgment of the Madras High Court concerning tariff concessions for High Tension Industries. The case arose from a series of writ petitions challenging the validity of amendments to tariff concessions under the Tamil Nadu Revision of Tariff Rates on Supply of Electrical Energy Act, 1978. The core issue was the interpretation of the term 'set up' in relation to the eligibility for tariff concessions. The High Court had previously ruled that the date of establishment of the industry was the relevant factor for determining eligibility for concessions, rather than the date of application for service connection. The appellants contended that the State intended to confer benefits on a specific class of consumers and that delays in granting connections should not penalize those who had established their industries. The respondents argued that the amendments were unreasonable and contravened statutory provisions. The Supreme Court upheld the High Court's interpretation, emphasizing that the term 'set up' should be understood as 'erect or establish', and clarified that the doctrine of promissory estoppel does not apply against statutory provisions. The court concluded that the amendments did not retroactively affect rights accrued under previous notifications, thereby affirming the entitlement of industries established before the cut-off date to the tariff concessions. The decision reinforced the importance of clarity in statutory language and the need for certainty in the application of tariff concessions.
