The dispute

Yukos Capital, a Luxembourg-incorporated finance company of the Yukos Group, lent money to its parent Yukos Oil under a December 2003 Loan (up to RUB 80 billion at 9%) and an August 2004 Loan (USD 355 million). Both loans were funded back-to-back and on a non-recourse basis by other group companies, Brittany Assets and Hedgerow. After Russia's tax reassessments of Yukos Oil for 2000–2004, the auction of Yuganskneftegaz and the bankruptcy of Yukos Oil, the Russian courts refused to admit Yukos Capital's claims under the loans, and Yukos Oil was struck off in November 2007. Yukos Capital claimed expropriation under Article 13 ECT and breaches of Article 10 ECT. Russia objected that it had never ratified the ECT, that intra-group loans were not investments, that it could deny the claimant the treaty's benefits under Article 17, that the tax carve-out in Article 21 applied, that the loans were part of illegal tax evasion, that the claim was an abuse of process, and that any loss was limited to the 0.0625% interest spread.

Key holdings

Jurisdiction upheld. Russia's provisional application of the ECT under Article 45(1) included its consent to arbitration under Article 26 (by majority). The loans were investments as debts of a company associated with an Economic Activity in the Energy Sector (by majority). Article 17 could not be invoked because nationals of a third State did not control the claimant on 11 April 2014. Interim Award on Jurisdiction (18 January 2017), ¶ 567, as recited in Final Award ¶ 28
Russia expropriated the loans in breach of Article 13 ECT. Excluding Yukos Capital's claims from the Yukos Oil bankruptcy was done without due process and was discriminatory, amounting to a denial of justice, as part of an orchestrated campaign against the Yukos Group. Having so found, the Tribunal did not decide the Article 10 claims. The remaining objections were also rejected: the investor-status objection, the Article 21 tax carve-out (the measures targeted Yukos Oil, not the claimant) and illegality (no proof of criminal intent to evade Russian tax). Final Award, operative part ¶¶ (1)–(2); ¶¶ 440–463, 558 (as summarised by the Swiss Federal Tribunal)
Causation and contribution (by majority). Sums advanced under the December 2003 Loan after Yukos Oil's public warning of bankruptcy on 27 May 2004 (drawdowns of 16, 22 and 28 June 2004) are reduced by 50% for the claimant's contribution to its own loss. The August 2004 Loan is irrecoverable because its proximate cause was the claimant's own decision to lend when it was reasonably foreseeable that the money would be lost. Rowley dissented on both points. Final Award ¶¶ 698–699, 787
The loss is the full value of the loan (principal plus interest), not the 0.0625% spread. The back-to-back arrangement with Brittany left Yukos Capital with a liability to Brittany, not a transfer of ownership in the loan, and under Chorzów Factory such liabilities are not deducted. Stern dissented on this point. Final Award ¶¶ 732–743
Valuation. The fair market value of the December 2003 Loan, excluding the effect of Russia's illegal acts, equals the principal advanced plus the contractual interest due and unpaid, with no discount. After the 50% reduction, the principal is RUB 77,342,764,401.89, converted at 29.40 RUB/USD on 31 December 2008 to USD 2,630,706,272.17. Final Award ¶¶ 786–789
No abuse of process and no prior recovery. The giga-dividend paid to Yukos Oil's shareholders and the Dutch Promneftstroy proceedings did not reduce the debt. The claimant must give credit for any future recoveries, in line with its undertaking. Final Award ¶ 825
Interest and costs. Russia pays unpaid contractual interest at 9% to 31 December 2008. Pre-award interest runs at 1% above the Russian rouble 3-month commercial lending rate until 31 December 2008, then at 1% above 6-month USD LIBOR; this was decided by majority, with Stern dissenting. Russia also pays EUR 1,557,508.42 in tribunal and registry costs and USD 20,552,462.46 in legal costs. Final Award, operative part ¶¶ (6)–(10)
Set-aside refused. The Swiss Federal Tribunal held that provisional application of Article 26 ECT was not shown to be inconsistent with Russian law, and that the burden of proving inconsistency lay on Russia. It also held that the loans were investments under Article 1(6) ECT whatever the origin of the funds, that there was no abuse of right, that illegality was not a jurisdictional question, and that the award was not contrary to public policy.
