Tamil Nadu Electricity Board & Anr vs Status Spinning Mills Ltd & Anr

The Supreme Court upheld the validity of the Tamil Nadu Revision of Tariff Rates on Supply of Electrical Energy Act, 1978, stating that it operates within the framework of 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 flexibility in setting rates based on production costs. The judgment confirmed the High Court's dismissal of the writ appeals filed by the Tamil Nadu Electricity Board and the State of Tamil Nadu, thereby affirming the lower court's decision.
