The dispute

World Wide Minerals Ltd (WWM), a Toronto-based mining company, and its President and CEO Paul A. Carroll won a 1996 tender to manage, and later acquire, TGK. TGK was a run-down state-owned uranium mining and processing complex near Stepnogorsk, Kazakhstan. WWM ran TGK under a Management Agreement of October 1996 and lent it US$12.7 million, secured by a pledge over TGK's assets. Kazakhstan refused WWM an export licence for uranium oxide sold to Consumers Energy in the USA, terminated the Management Agreement on 1 August 1997, and TGK went bankrupt. Relying on the Canada–USSR BIT, the claimants alleged expropriation, unfair and inequitable treatment, and breaches of rights to the Southern Mines under a Strategic Alliance Agreement. Kazakhstan argued that Russia, not Kazakhstan, was the successor to the treaty, that WWM had materially breached the Management Agreement, and that any breach caused no loss.

Key holdings

Jurisdiction upheld. The Tribunal held that Kazakhstan is a legal successor to the Canada–USSR BIT. Kazakhstan's attempt in 2018 to challenge this award under section 67 of the Arbitration Act 1996, 959 days out of time, was refused: the fresh evidence relied on (a letter from a minister of a non-disputing State) was not a 'game-changer' that could justify so long a delay. 2019 Judgment ¶¶ 3, 53–57; 2025 Judgment ¶ 14
In the 2019 Final Award, the Tribunal rejected the expropriation claim and found that the Strategic Alliance Agreement was only an agreement to agree, giving no vested rights to the Southern Mines. It held that Kazakhstan was entitled to terminate the Management Agreement because WWM had materially breached it. It found two breaches of fair and equitable treatment: the arbitrary handling of the export licence application, and the failure to give WWM timely notice of TGK's bankruptcy. 2020 Judgment ¶¶ 6–10 (Final Award ¶¶ 400, 422–423, 478–482, 532–533)
The Tribunal awarded US$13.7 million in sunk costs, plus interest and costs. It reasoned that the licence failure contributed to the demise of the investment and that the bankruptcy breach denied WWM a chance to protect its security interests. 2020 Judgment ¶¶ 17–18 (Final Award ¶¶ 587, 596)
Section 68(2)(a) challenge upheld. WWM had claimed damages only on the basis that all its alleged breaches together amounted to expropriation. The Tribunal therefore decided damages on a point that Kazakhstan had no fair opportunity to address. This caused substantial injustice, because the Tribunal might well have reached a different result given that WWM had no Southern Mines rights and that the termination was lawful. 2020 Judgment ¶¶ 48–56
The quantum paragraphs of the Final Award were set aside, and all issues of causation and quantification of loss were remitted to the Tribunal rather than simply annulled. 2020 Judgment ¶¶ 58–60
The two-member Tribunal's 2024 Award held that the export licence breach was 'a decisive factor that, together with others' caused the demise of the investment. It again awarded US$13.7 million in sunk costs and held that the bankruptcy claims had become moot. 2025 Judgment ¶ 21 (2024 Award ¶ 427)
Section 68(2)(d) challenge upheld. The Tribunal failed to deal with Kazakhstan's central counterfactual case: that even without the licence breach the Management Agreement would have been terminated and the investment lost. No interpretation request under Article 35 of the UNCITRAL Rules 1976 was required, because there was no ambiguity to interpret. The irregularity caused substantial injustice. The question of relief was reserved. 2025 Judgment ¶¶ 127–130, 144–153
