English Commercial Court Holds Sanctions Immunity Cannot Block Enforcement of Arbitral Award OWH v RTI and Rusal
|
1. Background
The dispute arose from a 2002 ISDA Master Agreement entered into between RTI Ltd, a Jersey-incorporated subsidiary of Russian aluminium producer United Company RUSAL, and German financial institution OWH SE i.L.
The agreement was governed by English law and provided for arbitration under the London Court of International Arbitration (LCIA) Rules. RTI's obligations were guaranteed by Rusal.
Following Russia's invasion of Ukraine in February 2022, extensive international sanctions were imposed against Russian individuals and entities. Against this backdrop, RTI failed to meet a substantial margin call arising from currency swap transactions.
RTI argued that making the required payment could expose it to sanctions-related legal risks. OWH subsequently terminated the relevant transactions and issued a termination notice.
RTI and Rusal challenged the validity of the termination and raised various sanctions-based arguments under UK, Jersey and Gibraltar sanctions legislation.
The dispute ultimately proceeded to LCIA arbitration.
2. The LCIA Awards and Subsequent Enforcement Proceedings
The LCIA tribunal ruled in favour of OWH in an award on liability dated 25 September 2024.
A further final award dated 29 August 2025 dealt with interest and costs. Taken together, the awards involved claims amounting to several hundred million euros.
Following the awards, RTI and Rusal initiated challenges and enforcement-related proceedings in multiple jurisdictions, including:
The objective of these proceedings was to resist or limit the enforcement of the arbitral awards.
In its judgment dated 1 May 2026, OWH SE i.L. v RTI Ltd & Anor [2026] EWHC 1015 (Comm), the English Commercial Court rejected Rusal's application to set aside or adjourn an order permitting enforcement of the award against Rusal in its capacity as guarantor.
The Court's decision focused particularly on whether statutory sanctions immunity could operate as an independent defence to enforcement.
3. The Court's Decision
The Commercial Court held that the immunity created by Section 44 of SAMLA, together with the corresponding Jersey provision under Article 46A, is ancillary to the substantive sanctions regime.
It does not operate as a free-standing shield against enforcement.
In other words, a party cannot simply point to the existence of sanctions and claim immunity from enforcement without establishing that enforcement or payment would actually contravene an applicable sanctions prohibition.
The Court also observed that there was no requirement for a party to invoke a sanctions defence merely because sanctions existed. However, where a party seeks to rely on sanctions-related illegality to defeat enforcement, the relevant illegality must have a proper factual and legal foundation.
Significantly, the Court found that no actual illegality had been properly pleaded or evidenced before the arbitral tribunal in the manner necessary to support the later enforcement objection.
The Court further noted that even if the award ultimately became unenforceable against RTI in Jersey following pending proceedings, that would not necessarily prevent enforcement elsewhere.
The award could still potentially be enforced against Rusal as guarantor in England.
4. Legal Analysis
A. Enforcement of Arbitral Awards under the Arbitration Act 1996
English law adopts a strong pro-enforcement approach towards arbitral awards.
Under Section 66 of the Arbitration Act 1996, an award may be enforced in England with the permission of the court. Challenges to enforcement are subject to limited grounds and do not ordinarily provide an opportunity for the parties to reopen the merits of the arbitration.
The enforcement court is therefore not functioning as an appellate tribunal.
Its role is to determine whether there exists a recognised legal basis for refusing enforcement, including circumstances where enforcement would conflict with public policy.
The OWH v. RTI and Rusal decision illustrates the English courts' reluctance to allow enforcement proceedings to become a vehicle for re-litigating issues that could and should have been addressed during the arbitration.
B. Sanctions Immunity Is Ancillary to the Sanctions Regime
One of the most important aspects of the judgment is its treatment of statutory sanctions immunity.
The Court's reasoning indicates that immunity provisions cannot be detached from the substantive sanctions provisions to which they relate.
A party seeking to rely on sanctions immunity must therefore establish a genuine connection between the enforcement action and an applicable sanctions prohibition.
The mere existence of sanctions affecting a party or its corporate group does not automatically make enforcement unlawful.
This distinction is particularly important in international arbitration because sanctions regimes are often complex, jurisdiction-specific and subject to exceptions, licences and regulatory permissions.
C. Late Sanctions Defences and Procedural Fairness
The judgment also reinforces a broader principle of English arbitration law: parties should raise their substantive and jurisdictional defences before the arbitral tribunal at the appropriate stage.
Where a party fails to establish that compliance with an obligation would constitute unlawful conduct during the arbitration, attempting to introduce substantially the same argument for the first time during enforcement proceedings may face significant judicial scrutiny.
This is particularly relevant where a late sanctions argument would have the practical effect of delaying enforcement of an otherwise final award.
The decision therefore highlights the importance of:
D. Comparative Relevance for India
The judgment also has comparative significance for Indian arbitration practice.
Indian courts dealing with enforcement of foreign arbitral awards generally operate within Part II of the Arbitration and Conciliation Act, 1996, including the limited public-policy grounds for refusing enforcement.
The reasoning in OWH v. RTI and Rusal may therefore provide a useful comparative reference where sanctions, illegality and public policy are raised in opposition to enforcement.
The dispute is particularly noteworthy because related enforcement proceedings have also been pursued in India, demonstrating the increasingly complex cross-border nature of enforcement involving multinational corporate structures.
5. Why the Development Matters
1. Reaffirms the Finality of Arbitral Awards
The judgment strongly reinforces the English courts' pro-arbitration and pro-enforcement approach.
Even politically sensitive disputes involving international sanctions will not automatically justify reopening or delaying enforcement of a final arbitral award.
2. Clarifies the Interaction Between Sanctions Law and Arbitration
The decision makes an important conceptual distinction between sanctions themselves and sanctions immunity.
Immunity cannot automatically operate as an independent defence. The party relying upon it must demonstrate the relevant legal connection between the sanctions regime and the enforcement action.
3. Warning to Sanctioned or Sanctions-Adjacent Parties
Entities connected with sanctioned jurisdictions cannot necessarily rely on generalised concerns regarding sanctions to frustrate enforcement.
Where a sanctions defence is genuinely available, it should be raised fully and properly during the arbitration and supported with evidence.
4. Importance of Cross-Border Enforcement
The dispute demonstrates the increasingly multi-jurisdictional character of high-value arbitration enforcement.
Proceedings involving the same awards have extended across Jersey, the Netherlands, England and India. This creates complex questions concerning guarantees, corporate structures, recognition, public policy and the interaction of different sanctions regimes.
6. Impact on Parties Involved in Sanctions-Related Disputes
For Financial Institutions and Counterparties
The judgment provides reassurance to financial institutions and commercial counterparties dealing with sanctioned or sanctions-adjacent entities.
It suggests that an arbitral award that has been properly obtained will not easily be defeated by sanctions arguments that were not properly raised or substantiated during the arbitration.
For Sanctioned or Sanctions-Adjacent Entities
For parties seeking to rely on sanctions-related defences, the decision sends a clear message: sanctions arguments should not be reserved for the enforcement stage.
A party should identify the relevant sanctions law, establish the alleged illegality and provide supporting evidence before the arbitral tribunal.
Failure to do so may significantly weaken a subsequent attempt to rely on the same argument to resist enforcement.
7. International Legal Significance
The decision forms part of a growing body of English and Commonwealth jurisprudence concerning the interaction between international sanctions and arbitration following the sanctions imposed in response to Russia's invasion of Ukraine.
The case is likely to attract attention in future disputes involving:
More broadly, the decision demonstrates the tension between two competing considerations: the need to respect evolving international sanctions regimes and the equally important principle that arbitration should provide a final and enforceable resolution of commercial disputes.
The English Commercial Court's approach indicates that sanctions cannot automatically displace the finality of arbitration without a properly established legal basis.
8. Conclusion
OWH SE i.L. v. RTI Ltd & Anor provides an important illustration of the English courts' approach to the intersection of sanctions law, arbitration and award enforcement.
The Commercial Court rejected the attempt to use statutory sanctions immunity as a generalised, after-the-fact shield against enforcement of a substantial LCIA award.
The central lesson is that the existence of sanctions does not, by itself, establish illegality or prevent enforcement. Where a party seeks to rely on sanctions as a defence, the relevant legal prohibition must be identified, established and supported by evidence.
The judgment also reinforces the fundamental principle of English arbitration law that enforcement proceedings are not an opportunity to re-litigate the merits or introduce defences that were not properly advanced before the arbitral tribunal.
Against the broader geopolitical backdrop of the Russia-Ukraine conflict, the decision is particularly significant. It confirms that while sanctions can materially affect the performance and enforcement of contractual obligations, they do not automatically override the strong judicial policy favouring the finality, certainty and enforceability of arbitral awards.
For international businesses, financial institutions, arbitral practitioners and States, the case serves as a timely reminder that sanctions-related objections must be addressed carefully and at the appropriate procedural stage.
