On July 18, 2014, the Arbitral Tribunal (Tribunal) constituted in accordance with Article 26 of the Energy Charter Treaty (ECT) and the 1976 UNCITRAL Arbitration Rules under the auspices of the Permanent Court of Arbitration issued its long-awaited final awards in the famous arbitral proceeding related to the demise of oil giant Yukos. The Tribunal held unanimously that a coordinated set of actions by the Russian government (including arrests, tax reassessments, fines, and the forced sale of Yukos) amounted to an indirect expropriation of Yukosin breach of Russia’s obligations under the ECT, and that Russia was liable to pay prompt, adequate, and effective compensation for that breach. The Tribunal concluded that Yukos’s claims were not barred by the company’s own illegal acts or because of the “carve-out” for taxation measures under Article 21 of the ECT. Instead, the Tribunal concluded that the claimants had contributed to the prejudice they suffered and it therefore reduced the awards and reimbursement for legal costs by 25 percent. Even accounting for this reduction, the composite final award is still, by far, the largest known arbitral award ever rendered. The Tribunal ordered the Russian Federation to pay damages totaling US$50,020,867,798, in addition to arbitral and legal costs. Post-award interest is due on any outstanding amounts of damages and costs not paid starting from January 15, 2015, and is to be compounded annually thereafter.
