In a landmark decision, Britain's highest judicial authority, the Supreme Court, upheld an injunction on Tuesday, effectively blocking a Gazprom subsidiary, RusChemAlliance LLC, from advancing a €450 million claim against UniCredit Bank AG in Russia. This ruling stems from the German bank's decision to suspend financing designated for gas processing plants, citing compliance with European Union sanctions.

Top UK Court Blocks Gazprom Unit's Russian UniCredit Claim: Judicial Decision Upholds Injunction

The case, which has captured significant legal attention, centers around UniCredit's refusal to fulfill financial obligations under seven bond contracts due to sanctions imposed in the wake of the ongoing conflict in Ukraine. RusChemAlliance's attempt to initiate litigation in Russia was deemed a breach of the original arbitration agreement with UniCredit, which specifies arbitration in Paris under English law.

Justice Robert Reed articulated the court's stance, stating that the “declaration and injunction relief” affirmed by the Court of Appeal on January 29 will continue to be enforced. This development halts the proceedings in the arbitrazh court of St Petersburg, Russia, which have been adjourned until May 6, pending the detailed reasoning from the Supreme Court, to be disclosed subsequently.

RusChemAlliance's approach to the Supreme Court on April 17 was to overturn the initial anti-suit injunction that restrained them from proceeding with the litigation in Russia. Counsel for RusChem argued the illogicality of having the arbitration clause governed by English law. However, the counterargument, led by UniCredit's legal representatives, highlighted this as a pioneering instance where English courts issued an anti-suit injunction against a foreign entity in a foreign-seated arbitration context.

Broader Impact on International Banking and Arbitration

The decision underscores the complex interplay between international banking, legal arbitration, and geopolitical tensions. UniCredit, unlike its counterparts Deutsche Bank and Commerzbank, which have previously secured similar injunctions, maintains assets in Russia, complicating its compliance landscape.

Moreover, this ruling affects other financial and construction entities involved in similar disputes. For instance, Linde Engineering halted its construction of a natural gas plant in the St. Petersburg region after identifying that exporting the gas would violate EU sanctions, leading to RusChem demanding repayment of more than €738 million in advance payments.

Conversely, UniCredit's defense is bolstered by Stephen Houseman KC, Stuart Cribb of Essex Court Chambers, and Jonathan Harris KC of Serle Court, under the instruction of Latham & Watkins LLP.

The case, officially titled UniCredit Bank GmbH v. RusChemAlliance LLC, case number 2024/0015, continues to develop in the Supreme Court of the United Kingdom, with both parties awaiting the full judicial opinion that will provide further clarity on the international legal standards applicable in cases influenced by geopolitical sanctions.
