Singapore Legal Ruling Upholds $490M Award

The court ruling delivered on August 26, 2026, rejected all applications brought by Tata Power seeking to set aside two arbitral awards issued by the Singapore International Arbitration Centre (SIAC) in favor of investment firm Kleros Capital Partners Limited.

The original dispute relates to a 2013 non-disclosure agreement to jointly bid for a coal deposit in Krutogorovo, Russia. Arbitration tribunals found that Tata Power breached confidentiality duties and good faith commitments by misusing shared geological data to acquire the mining license through a subsidiary while excluding Kleros.

The SICC upheld the tribunal's damages award of $490.32 million plus 5.33 percent annual interest accrued since November 2020. Legal counsel for Kleros noted that the total claim liability, including interest and legal fees, currently exceeds $640 million.

Corporate Disclosure and Intended Appeal

In a regulatory filing submitted under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, Tata Power disclosed the adverse judgment to domestic exchanges.

The company confirmed its intention to contest the decision before higher judicial authorities. Under Singapore civil procedure rules, Tata Power has 28 days from August 26, 2026, to file a formal appeal before the Singapore Court of Appeal.
