Amount: Claimed in the Statement of Claim: not less than USD 466,981,199. Final claim: USD 53,889,425 (capital transfer), USD 166,341,793 (loss of J&S Energy value), USD 33,284,256 (business and reputation), USD 3,587,373 (compliance), USD 6,770,631 (cancelled IPOs), plus interest of USD 134,329,565 (alternatively USD 39,705,867). Awarded: nothing. Costs of the arbitration (EUR 566,646.55 and CHF 7,239.10) split 75% Mercuria and 25% Poland. After netting the parties' costs, Mercuria owes Poland EUR 1,726,136.03, plus interest at three-month Euribor + 1%.

The dispute

Mercuria, a Cypriot holding company, acquired all the shares of the Polish fuel importer J&S Energy SA from its two Polish founders in July 2004. Poland's mandatory fuel reserves legislation required importers to raise their stocks step by step. The Minister of Economy refused J&S Energy's applications for exemptions from increasing its reserves. The Material Reserves Agency (ARM) then imposed a fine of PLN 461,695,807.24 (16 October 2007), which the Minister quashed. ARM imposed a second fine, which the Minister confirmed at PLN 452,045,537.36 on 5 June 2008; J&S Energy paid it on 30 June 2008 with a USD 212.9 million loan from Mercuria. Mercuria claimed that Poland breached Article 10(1) ECT (fair and equitable treatment, unreasonable and discriminatory measures, constant protection and security); it withdrew an expropriation claim under Article 13. Poland objected that the real investors were Polish nationals, that the fork-in-the-road clause applied because of the proceedings in the Polish courts, and that the claim was not ripe; on the merits it argued that it had applied its reserves law correctly and even-handedly.

Key holdings

Jurisdiction upheld unanimously. Mercuria is an Investor because it is incorporated in Cyprus. Buying the existing shares in J&S Energy was an Investment under Articles 1(6) and 1(8) ECT. The ECT does not make the national origin of the capital relevant. The Tribunal found no abuse of rights or sham structure that would justify lifting the corporate veil. Award on Jurisdiction ¶¶ 81–86
Poland's Annex ID fork-in-the-road reservation (Article 26(3)(b)(i) ECT) did not bar the claim. The Polish appeal was brought by J&S Energy, not by Mercuria. It was a public-law challenge to the fine, which is a different dispute from a treaty claim for damages. The Tribunal also refused to dismiss for lack of a prima facie case and refused to suspend the arbitration pending the Polish proceedings. Award on Jurisdiction ¶¶ 91–96, 102–104, 108
No breach of fair and equitable treatment. Applying the Saluka standard, the Tribunal found that the refusals of the exemption applications were reasonable, because compliance was not impossible for reasons outside J&S Energy's control. The inspections, the ABW raid, the prosecutions, the imposition and confirmation of the fines and their execution were neither unfair nor inequitable. Procedural shortcomings found by the Polish courts were not serious enough to amount to a denial of due process. Final Award ¶¶ 224, 301–302, 365–366, 439, 499, 517, 535
The cumulative effect of Poland's conduct from February 2006 onwards may be assessed. Here, however, there was no wrongful purpose or aggravating factor that would make the conduct, taken as a whole, a breach of Article 10(1). Final Award ¶¶ 229, 570–573
No discrimination under the Plama test. PKN Orlen, the other companies granted exemptions and the entities not fined were not in similar circumstances to J&S Energy. The unreasonable-measures claim was subsumed in the fair and equitable treatment analysis. The constant protection and security claim added nothing to it. Causation and damages were therefore not reached. Final Award ¶¶ 577–579, 643, 787–789, 795–797
Costs follow the event in each phase. Mercuria recovers its jurisdictional-phase costs of EUR 596,800.74; the fees of Weil, Gotshal & Manges LLP were disallowed as not justified. Poland recovers its merits-phase costs of EUR 2,322,936.77. The costs of the arbitration are borne 75% by Mercuria and 25% by Poland. Final Award ¶¶ 813–822, 824
In a later dispute, Mercuria sought to enforce a 2022 award from a separate SCC arbitration about interest on the refunded fine. The U.S. court held that it had jurisdiction under the FSIA arbitration exception. It refused enforcement under Article V(1)(e) of the New York Convention because the Svea Court of Appeal had annulled that award on the basis of Komstroy, and the annulment was not repugnant to U.S. public policy. Each party bears its own costs. D.D.C. Memorandum Opinion, pp. 6–17
