Concessional Tariffs for High Tension Industries Linked to Business Readiness, Not Service Connection Date.

The SC held that the term "set up" in the context of concessional tariffs for High Tension Industries should be interpreted as the date when the industry is ready to commence business, not merely when the service connection is obtained. The State has the power to withdraw or amend tariff concessions, and the doctrine of promissory estoppel does not prevent such changes if justified by public interest. The Court directed that individual cases be reviewed by the Appropriate Authority, ensuring that industries ready for commercial production before the cut-off date can continue to benefit from the concessional tariff. The appeals were allowed with these directions.

Issues Involved:
1. Connotation of the expression "set up" in the context of concessional tariff for High Tension Industries.
2. Construction of the expression "set up" in the context of continued tariff concession.
3. Interpretation of "set up" in relation to the date of service connection.
4. Ensuring certainty among consumers regarding the tariff concession.
5. Liberal construction of the Notification conferring tariff concessions.

Detailed Analysis:

Issue 1: Connotation of "set up" in the context of concessional tariff
The Supreme Court examined the meaning of "set up" in the context of concessional tariffs granted to High Tension Industries. The term "set up" was debated whether it should mean the date of obtaining the service connection or the date when the industry is ready to commence business. The Court referenced the decision in *Commissioner of Wealth Tax v. Ramaraju Surgical Cotton Mills, Ltd.*, where "set up" was interpreted to mean when the unit is ready to discharge its function. The Court concluded that "set up" should be understood as the date when the industry is ready to commence business, not merely when the service connection is obtained.

Issue 2: Construction of "set up" in the context of continued tariff concession
The Court analyzed whether the expression "set up" should be construed in the context of the continued tariff concession until the expiry of three years from the date of service connection. It was determined that the term "set up" should be interpreted to ensure that industries which had already been established and were ready for commercial production before the cut-off date should continue to avail the concessional tariff.

Issue 3: Interpretation of "set up" in relation to the date of service connection
The Court deliberated on whether the expression "set up" should take its meaning from the context that the continued tariff concession could be availed by the High Tension Industries until the expiry of three years from the date of service connection. The Court emphasized that the date of service connection is crucial as it provides certainty about when the concession period starts. The notification dated 31.01.1995 specified that the concessional tariff would apply from the date the consumer is given a service connection, thus linking "set up" to the readiness to consume electrical energy.

Issue 4: Ensuring certainty among consumers regarding the tariff concession
The Court stressed the importance of ensuring certainty among consumers who could continue to avail of the tariff concession. The date on which the consumer is given a service connection provides such certainty. The Court noted that the benefit of concession in tariff rates could only be availed once the service connection is granted, thereby ensuring a clear and definite starting point for the concessional period.

Issue 5: Liberal construction of the Notification conferring tariff concessions
The Court discussed whether the Notification conferring tariff concessions should be construed liberally to extend the benefit by interpreting the expression "set up" and introducing the element of uncertainty. The Court concluded that while exemption notifications should receive a strict construction, once it is found that the industry is entitled to the benefit of the exemption, it should receive a broad construction. The Court also noted that the State has the power to withdraw or modify the concession in public interest, and such decisions should be balanced against the hardship caused to the consumers.

Conclusion:
The Supreme Court held that:
1. The State had the power to withdraw the concession.
2. The doctrine of promissory estoppel did not bar the State from amending the Schedule.
3. Public interest justified the amendment, negating the doctrine of promissory estoppel.
4. The proviso to the main provision should be read down to include industries that had started commercial production and were ready for service connection before the cut-off date.
5. Individual cases should be examined by the Appropriate Authority of the Board as directed by the High Court.

The appeals were allowed with these directions, ensuring that the interpretation of "set up" aligns with the readiness to commence business and the date of service connection, providing clarity and fairness to the consumers.
