Tata Power Files Criminal Complaint Against Kleros Capital Over $490 Million Arbitration Award
Tata Power has escalated its long-running dispute with Kleros Capital Partners from the courtroom to the police station, with Mumbai Police registering a First Information Report against eight accused parties over an alleged fraud valued at ₹4,800 crore.
As reported by the Free Press Journal, the complaint names Kleros Capital Partners and two former Tata Power employees among the accused, alleging data leakage and criminal conspiracy in connection with a Russian coal mine transaction and the Singapore arbitration that followed.
Tata Power claims that confidential information shared with Kleros under non-disclosure agreements signed in 2013 and 2014 was later used against it in arbitration. It alleges direct losses of roughly $8 million and says a valuation report was prepared without a site visit before being relied upon in the proceedings. None of the allegations has been established in any court.
Kleros commenced SIAC arbitration in November 2020. The tribunal, chaired by Professor Lawrence Boo and including Stuart Isaacs KC and Amal K. Ganguli, issued a liability award in September 2023 and a damages award on 1 July 2025, with the majority ordering payment of $490.32 million plus simple interest at 5.33% per annum.
On 26 August 2026 the Singapore International Commercial Court rejected all three of Tata Power's set-aside applications, finding no breach of natural justice or apparent bias. The Court also held that Omni Bridgeway's involvement in unrelated proceedings involving the arbitrators did not establish apparent bias. Tata Power shares fell 3.89% following the ruling.
