Case Note & Summary
The dispute arose from a contract between Hindustan Zinc Ltd and Friends Coal Carbonisation for the supply of metallurgical coke. The appellant issued a tender on 14.10.1991, and the respondent submitted an offer which was accepted, leading to a purchase order for 15,000 MT of coke. The contract included a price variation clause based on coal prices as of 8.11.1991. The respondent initially used Washery Grade II coal but switched to Washery Grade I coal due to quality issues. Disputes over price escalations led to arbitration, where the tribunal awarded the respondent an escalation amount based on the price of Washery Grade II coal, which the appellant contested. The trial court partially upheld the respondent's claims but limited the escalation based on Washery Grade I coal. The High Court later reversed this decision, leading to the current appeal. The Supreme Court analyzed the arbitration award and the contract terms, emphasizing that the escalation should be calculated based on the actual coal used. The court found that the tribunal erred in applying the base price of Washery Grade II coal for the escalation calculation when Washery Grade I coal was used. The Supreme Court restored the trial court's judgment, confirming the correct escalation amount and ordering the respondent to refund a previously deposited amount with interest.
Headnote
A) Arbitration - Price Escalation - Calculation Methodology - Arbitration and Conciliation Act, 1996, Section 34 - The court held that the price escalation for metallurgical coke must be calculated based on the base price of washery grade I coal for supplies made after 14.7.1992, as the respondent had switched to using washery grade I coal. The award of the Arbitral Tribunal was found to be in violation of the contract terms by incorrectly applying the base price of washery grade II coal for escalation calculations. Held that the trial court's judgment was correct and should be restored (Paras 24-24).
Issue of Consideration
Whether the price escalation for metallurgical coke should be calculated based on the base price of washery grade I coal or washery grade II coal.
Final Decision
The Supreme Court allowed the appeal, set aside the High Court's judgment, and restored the trial court's decision, confirming the escalation amount based on washery grade I coal prices. The respondent was ordered to refund a previously deposited amount with interest.
