GRAPHITE INDIA LTD. vs DURGAPUR PROJECTS LTD.

The Supreme Court ruled that the increase in electricity tariff by Durgapur Projects Ltd. (DPL) was contrary to Section 57 of the Electricity (Supply) Act, 1948, and the statutory requirements of Schedule VI of that Act. The Court upheld the Calcutta High Court's decision that had favored Graphite India Ltd. in its challenge against the tariff hike. Consequently, the appeal by DPL was dismissed, affirming the High Court's ruling that the tariff increase lacked proper approval and was thus invalid.
