As per case facts, OPG Power Generation Pvt. Ltd. (Appellant) had a power supply agreement with Shree Karthik Papers Ltd. (Respondent). The Appellant unilaterally increased the power tariff, which the ... Respondent protested, citing no contractual provision for such an increase. Despite protests, the Appellant stopped power supply. The Appellant contended the stoppage was due to non-payment, but the tariff increase was deemed unilateral. The Respondent was forced to procure power at a higher rate and sought damages. An Arbitrator found the Appellant in breach and awarded damages, which was upheld by a Single Judge. The present Appeal challenged this decision. The question arose whether the Appellant was justified in stopping electricity supply and unilaterally increasing the tariff, or if its actions constituted a breach of contract. Finally, the Supreme Court ruled that both the arbitrator and the Single Judge correctly concluded the Appellant was the first to breach by unilaterally raising the tariff and stopping supply without following agreed procedures, even if there was a delayed payment. The Court dismissed the Appeal, finding no grounds to interfere with the lower judgments.
