The Company sought further legal remedies and filed an appeal against this order before the Hon’ble High Court of Calcutta (Division Bench). This appeal is pending before the Hon’ble High Court of Calcutta. On January 17, 2025, the Company received a demand from the Ministry of Steel to make payment towards outstanding balance of SDF loan. During FY2026, the Company discharged its liability towards JPC aggregating to ₹2,970 crore, without prejudice to its rights and contentions in the appeal.

Accordingly, the Company filed an Interim Application bearing IA no. GA/2/2026 before the Hon’ble High Court of Calcutta seeking injunction on JPC utilizing the said amount of ₹2,970 crore. The IA NO. GA/2/2026 was heard by the Hon’ble High Court of Calcutta on September 17, 2026. As per the order of the Hon’ble High Court of Calcutta dated September 17, 2026 received by the Company today i.e. September 18, 2026, Hon’ble High Court has disposed of the interim application with the direction that till the appeal is disposed of, the fund shall not be utilised or disbursed to third parties.
