Uniper Global Commodities and Metha-Methanhandel brought a Stockholm-seated ad hoc arbitration against Gazprom Export, claiming it failed to deliver gas under long-term contracts from June 2022. In June 2024, the tribunal awarded them more than €13B and confirmed termination of the contracts, but sanctions and Russian anti-suit penalties have stalled enforcement. In January 2026, the Versailles Court of Appeal lifted a Uniper attachment and a Russian court enjoined a subsidiary’s ICC claim.
Latest development Jan 12, 2026
On January 12, 2026, the Arbitrazh Court of St Petersburg enjoined Uniper subsidiary Lubmin-Brandov Gastransport from pursuing its roughly €45M ICC claim, seated in Geneva, over unpaid OPAL pipeline transit under a 2012 contract. The court threatened penalties up to the full value of the claim.
Why it matters
The case tests whether European gas buyers, holding roughly €19.5B in claims against Gazprom, can enforce Western awards. Russian courts answer such claims with anti-suit injunctions under Articles 248.1 and 248.2 of the Arbitrazh Procedure Code, backed by penalties equal to the claim value.
Background
Uniper, the German gas importer, bought gas from Gazprom Export under long-term supply contracts. From June 2022, Gazprom Export curtailed and then halted deliveries, and supplies via Nord Stream 1 later stopped entirely. Uniper had to buy replacement gas at crisis prices. A German state rescue followed and ended in Uniper’s nationalization.
In November 2022, Uniper Global Commodities SE and its affiliate Metha-Methanhandel GmbH commenced an ad hoc arbitration seated in Stockholm, claiming some €14.3B. Gazprom Export responded in the Russian courts. On March 15, 2024, the Arbitrazh Court of St Petersburg enjoined the claimants from pursuing the arbitration on pain of a penalty equal to the full €14.3B claim. The tribunal nonetheless issued its award in June 2024. It granted Uniper damages of more than €13B for undelivered volumes and confirmed its right to terminate the contracts. On July 4, 2024, a Russian cassation court upheld the injunction and penalty.
Sanctions, the mirror-image Russian penalty, and the scarcity of attachable Gazprom Export assets have left the award effectively unenforced. On January 8, 2026, the Versailles Court of Appeal refused to recognize a German order requiring Gazprom Export to advance more than €3.6B for substitute gas. The court held that email service three days before the deadline, outside Hague Convention channels, denied Gazprom Export a fair chance to defend. It refused recognition under Article 45(1)(b) of the Brussels I Recast and lifted Uniper’s €364M attachment over debts owed by Engie to Gazprom.
The dispute has also opened a new front. Uniper subsidiary Lubmin-Brandov Gastransport GmbH (LBTG) brought a roughly €45M ICC claim seated in Geneva over unpaid OPAL pipeline transit under a 2012 contract. On January 12, 2026, the Arbitrazh Court of St Petersburg enjoined that arbitration too, threatening penalties up to the claim’s full value. The dispute forms part of a wider anti-suit injunction conflict between Russian and EU courts. European buyers hold roughly €19.5B in claims against Gazprom over halted deliveries.

Uniper is most likely to report no recovery on its €13 billion award by December 31, 2027 (88%). Gazprom Export holds few attachable assets in Europe. The Versailles Court of Appeal lifted Uniper’s only reported attachment in January 2026, and Russian anti-suit penalties deter any settlement.
How it resolves. Resolves on Uniper’s public statements, financial reports, or court records available by December 31, 2027. “Enforcement recovery” applies if Uniper reports receiving any sum from Gazprom Export or its assets through attachment, garnishment, or court-ordered enforcement of the award or related orders. “Settlement” applies if Uniper and Gazprom Export announce a concluded settlement or payment agreement covering the award. Otherwise, “no recovery” applies.
Reasoning
Starting point. Enforcement of large Western arbitral awards against sanctioned Russian state-linked companies protected by Russian anti-suit injunctions: Recovery on such awards within a few years is rare. Most post-2022 awards against Russian energy firms remain largely unpaid, with only occasional partial attachments, perhaps under 15% within a two-year window.
Awards against sanctioned Russian state-linked companies are seldom paid within a few years, and partial attachments are the usual ceiling. This record points below even that low base rate. Uniper’s one reported attachment, €364 million over Engie’s debts to Gazprom, was lifted when the Versailles Court of Appeal refused to recognize the German advance-payment order on January 8, 2026. The record shows no pending appeal or new attachment. Russian courts have answered each Uniper step with anti-suit injunctions carrying penalties equal to the claim value, and they did so again on January 12, 2026. That mirror penalty discourages Gazprom Export from paying voluntarily. The leading alternative is a successful new attachment of receivables owed to Gazprom Export by European counterparties, which is why enforcement recovery sits near 9%. A settlement is a long shot because German state ownership of Uniper and EU sanctions limit any deal. Nothing decisive is scheduled within 36 months, so the question stays open by design and “no recovery” dominates. The record is also 8.4 months old, which adds uncertainty about unreported enforcement steps.
Versailles ruling lifted Uniper’s only reported attachment · Scarce attachable Gazprom Export assets in Europe · Russian anti-suit penalties equal to full claim value · EU sanctions and German state ownership constrain settlement · Record is 8.4 months stale on enforcement steps
