Rajeshwar Thakur & Anr vs Bihar State Electricity Board & Ors

The Supreme Court upheld the validity of the Tamil Nadu Revision of Tariff Rates on Supply of Electrical Energy Act, 1978, stating that it does not conflict with the Electricity (Supply) Act, 1948. The Court emphasized that the State Government has the authority to amend tariff rates under Section 4 of the 1978 Act, which allows for adjustments based on production costs. The judgment affirmed the High Court's decision to dismiss the writ appeals filed by the Tamil Nadu Electricity Board and the State of Tamil Nadu, thereby maintaining the tariff concessions for High Tension industries as per the G.O. issued.
