The court also found no on the part of the majority arbitrators despite their undisclosed appointments in unrelated cases involving , the behind Kleros.
Background: From Confidential Information to Arbitration
The dispute originated in , when Kleros approached Tata Power as a potential co-investor to develop the Krutogorovo coal deposit in Russia, estimated to contain 1.1 billion tons of coal. The parties entered into two (NDAs) in and , under which Kleros shared confidential information about the deposit and the process for securing a mining licence.
The NDAs imposed on Tata Power obligations of , , and . The relationship deteriorated in amid disagreements over equity participation—Kleros sought 26% to 60% while Tata offered only 10%—and the relationship effectively ended in .
After the NDAs expired in , Tata Power, through its Russian subsidiary , submitted a bid for the mining licence and obtained it in . Tata Power later determined the project unviable and surrendered the licence. Kleros commenced arbitration in , alleging that Tata Power had misused confidential information and acted in bad faith to exclude it from the project.
In a unanimous in , the tribunal found Tata Power had breached the NDAs. In the phase, a majority comprising Professor Lawrence Boo and Stuart Isaacs KC awarded Kleros US$490.32 million for the loss of its chance to participate in the project. The third arbitrator, AK Ganguli SA, dissented, arguing for only US$13.5 million in negotiating damages.
The Challenge: and
Tata Power argued that the majority had abdicated its duty by failing to apply its mind to essential issues of , , and . It contended that the tribunal had not conducted a proper "but-for" analysis and had ignored the parties' agreement on a "no breach" counterfactual. On the issue of , Tata submitted that the tribunal failed to assess whether Kleros's loss was too remote. With respect to , Tata claimed the tribunal wrongly declared the duty of irrelevant without giving the parties an opportunity to be heard.
Additionally, Tata Power raised a challenge of , asserting that Professor Boo and Mr Isaacs KC had failed to disclose appointments in unrelated arbitrations involving , and that Professor Boo had a close personal and professional relationship with Benjamin Hughes, a member of 's investment committee.
Kleros countered that the award contained extensive consideration of all three issues. It pointed to specific paragraphs showing the tribunal's analysis of under Issues 1(a) and 1(b), its treatment of under the same framework, and its detailed rejection of Tata's arguments on the facts. On bias, Kleros stressed that none of the undisclosed appointments were made by , the parties, or their counsel, and that Professor Boo had categorically stated he never discussed with Mr Hughes.

. The court quoted the well-established principle that
"only irregularities that are egregious and occasion
justify judicial intervention."
The court determined that Tata Power had advanced a new ground—the "no breach scenario" counterfactual—that was not raised in its supporting witness statement, and that this ground was time-barred. Nonetheless, the court addressed the merits and found that the tribunal had indeed considered . The judgment noted:
"While there are aspects of the Award that could have benefited from clearer drafting, we do not engage in an exercise concerning literary precision – the Majority's reasoning need only be discernible. The court is not concerned with the quality of the award or the depth of its analysis but the fact or existence of analysis."
On , the court found that the tribunal had addressed it together with under Issues 1(a) and 1(b), and that the test from McGregor on Damages was applied throughout the award. As for , the court noted that the tribunal devoted twelve pages to the issue, concluding that the principle was of little legal relevance but nonetheless rejecting Tata's factual arguments.
The court further observed that Tata's complaints were
"in substance, a disguised attempt (borne out of counsel's ingenuity) at attacking the merits of the Majority's decision."

As for Professor Boo's relationship with Benjamin Hughes, the court found no evidence of a sufficiently close connection. Professor Boo's uncontroverted statement that he never communicated with Mr Hughes about was decisive. The court rejected the LinkedIn post relied upon by Tata, describing it as a routine farewell message.
The judgment stated:

The court also gave appropriate weight to the 's earlier decision rejecting the same challenge, viewing it as evidence of the views of reasonable observers.
The Decision and Its Implications
The dismissed all three applications—OA 13 (bias challenge), OA 24 ( award), and OA 25 ( )—with costs. Tata Power was ordered to pay Kleros's costs, with the amount to be determined if parties cannot agree.
Tata Power has 28 days to appeal to the , and the company has already announced its intention to do so. The stock fell over 4% on the day following the judgment as investors assessed the potential financial implications.
