On August 20, 2017, Justice Sir Jeremy Cooke delivered a pivotal ruling in the DIFC Court of First Instance, addressing the enforcement of two LCIA arbitration awards against the Kurdistan Regional Government (KRG) totaling over USD 2 billion. The KRG had sought to set aside an ex parte recognition order and an order for alternative service, arguing that the court lacked jurisdiction and that the service of documents had failed to meet international treaty obligations. While the Court upheld the recognition of the awards, it struck down the alternative service order, marking a significant moment for practitioners navigating the intersection of state immunity and procedural compliance.
For cross-border litigators and arbitration counsel, this decision serves as a stark reminder that even where a state entity has contractually waived its sovereign immunity, the DIFC Courts will not permit the circumvention of mandatory international service treaties. The ruling clarifies that while the DIFC’s procedural rules are designed to prevent obstruction by recalcitrant debtors, they cannot override the specific requirements of the Riyadh Convention when the UAE and the defendant’s home jurisdiction are both signatories. The case underscores the delicate balance the DIFC must strike between maintaining its reputation as a pro-enforcement hub and ensuring that its procedural shortcuts do not invite challenges to the validity of its own judgments.
How Did the Dispute Between Pearl Petroleum and the KRG Arise?
The genesis of the conflict between Pearl Petroleum Company Limited and the Kurdistan Regional Government of Iraq (KRG) provides a textbook illustration of the volatile intersection between sovereign ambition and international energy investment. At its core, the dispute highlights the high-stakes nature of energy sector arbitration and the subsequent, often labyrinthine, challenges of enforcing multi-billion-dollar awards against governmental entities. When a state acts as a commercial partner, the initial alignment of interests can rapidly deteriorate into a jurisdictional battleground where the sovereign attempts to shield its assets behind the veil of state immunity.
The factual matrix began during a period of aggressive hydrocarbon development in the Kurdistan Region of Iraq, a constituent region of the Federal Republic of Iraq. On 4 April 2007, the KRG, acting as the governmental entity for the region, entered into a long-term development and production agreement with Dana Gas PJSC. The contract was designed to exploit the region's substantial gas reserves, requiring massive upfront capital expenditure and technical expertise from the private sector. To distribute the financial risk and operational burden, the corporate structure evolved rapidly. On 17 October 2007, Dana Gas assigned a 50% interest in the Contract to Crescent Petroleum Company International Limited. Subsequently, on 5 February 2009, both Dana Gas and Crescent Petroleum assigned their respective interests to Pearl Petroleum Company Limited, consolidating the claimant block that would eventually initiate the arbitration.
Recognising the inherent risks of contracting with a sovereign entity in a politically complex region, the foreign investors demanded robust dispute resolution mechanisms. The 2007 contract was governed by English law and mandated that any disputes failing mediation would be resolved through arbitration in London under the rules of the London Court of International Arbitration (LCIA). Crucially, the drafters anticipated the exact defense the KRG would later deploy. The 23rd bullet point of Annexure 2 to the contract contained an explicit waiver, stating that the KRG waives on its own behalf and that of the KRG any claim to immunity for itself and its assets. While the drafting contained a minor typographical error—repeating "KRG" instead of referencing the Kurdistan Region of Iraq (KRI)—the commercial intent was unequivocal: the state was entering the market as a private actor and stripping itself of sovereign protections in the event of a breach.
As the commercial relationship fractured over delayed payments and disputed production entitlements, the claimants invoked the LCIA arbitration clause. The resulting arbitral proceedings in London were protracted and fiercely contested, ultimately yielding three separate awards in favour of Pearl Petroleum, Dana Gas, and Crescent Petroleum. While the first award was primarily declaratory in nature, establishing the KRG's liability, the subsequent two awards quantified the financial devastation of the breach. The tribunals ordered the KRG to pay staggering sums, of which over USD 2 billion (bn), remains unpaid.
Securing a USD 2 billion arbitral award against a sovereign entity is merely the first phase of a much longer war of attrition. State actors rarely satisfy such massive liabilities voluntarily, forcing award creditors to embark on global asset-hunting campaigns. The claimants strategically targeted the Dubai International Financial Centre (DIFC) Courts as their enforcement jurisdiction. The DIFC offers a sophisticated, English-language common law environment with a proven track record of enforcing arbitral awards, even against politically connected or state-affiliated entities. The claimants' strategy echoed the aggressive enforcement postures previously validated in landmark DIFC jurisprudence, such as the approach seen in ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC, where the DIFC Courts demonstrated their willingness to act as a conduit jurisdiction against recalcitrant debtors.
On 29 May 2017, the claimants secured a critical initial victory. Justice Sir Jeremy Cooke granted an ex parte order recognising the two LCIA awards and permitting alternative service of the order on the KRG’s London solicitors, who had represented the government during the arbitration. The ex parte mechanism is a standard procedural tool in the DIFC for the recognition of arbitral awards, designed to prevent the debtor from dissipating assets before the enforcement net can be cast. However, the sheer scale of the debt and the sovereign status of the defendant guaranteed a fierce counter-attack.
The KRG refused to capitulate, launching a comprehensive legal challenge aimed at dismantling the DIFC Court's jurisdiction and the procedural validity of the enforcement orders. The government's defensive strategy was twofold: first, it resurrected the shield of sovereign immunity, arguing that the DIFC Courts lacked the fundamental jurisdiction to adjudicate enforcement proceedings against a foreign state entity; second, it attacked the mechanics of service, arguing that the alternative service order bypassed mandatory international treaty obligations.
The KRG's reliance on sovereign immunity required the DIFC Court to navigate the delicate boundary between public international law and private commercial obligations. The KRG's counsel argued that the doctrine of state immunity, whether absolute or restrictive, precluded the DIFC Courts from exercising jurisdiction over the government of the Kurdistan Region. This argument, however, collided directly with the express terms of the 2007 contract. Justice Sir Jeremy Cooke rejected the KRG's attempt to disavow its commercial commitments, ruling that the contractual waiver of immunity was binding and extended to enforcement proceedings. The Court affirmed that the enforcement of an Award as a result of a waiver of immunity is based on consensual obligations undertaken in a commercial context, rather than an imposition of sovereign power by the forum state.
Furthermore, the Court emphasized that by agreeing to an English-seated arbitration, the KRG had inherently submitted to the supervisory jurisdiction of the English courts and the enforcement mechanisms that flow from such an agreement. The choice of seat is not merely a geographical convenience; it carries profound legal consequences regarding the waiver of jurisdictional immunity.
It is clear that the KRG entered into an agreement to arbitrate in London under the auspices of the LCIA and that in agreeing to London as the seat of the Arbitration, it also agreed to the English Court as the supervisory court.
Building upon this foundation, Justice Cooke concluded that the KRG's submission to the arbitral process and the supervisory courts in London irrevocably waived its right to claim immunity from the enforcement of the resulting awards. The contractual waiver in Annexure 2 was not a hollow promise; it was a fundamental pillar of the bargain that induced the foreign investors to commit billions of dollars to the region's infrastructure.
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
While the KRG's substantive defense of sovereign immunity collapsed under the weight of its own contractual drafting, its procedural defense regarding service proved far more formidable. The KRG argued that even if the DIFC Court had jurisdiction to recognise the awards, the method of serving the ex parte order was fatally flawed. The Court had permitted alternative service on the KRG's London solicitors, a pragmatic solution often employed when dealing with evasive commercial defendants. However, the KRG argued that service upon a state entity in Iraq must comply strictly with the Riyadh Convention, a multilateral treaty governing judicial cooperation to which both the United Arab Emirates and Iraq are signatories.
This procedural clash exposes a critical vulnerability in the enforcement of awards against states. Even when a state waives its substantive immunity, it can still weaponize procedural rules and international treaties to delay or derail execution. The DIFC Courts, while commercially pragmatic, are bound by the strictures of procedural fairness and treaty obligations. The tension between the initial ex parte recognition and the subsequent requirement for valid service is a recurring theme in DIFC enforcement jurisprudence, echoing the procedural safeguards later scrutinized in cases like ARB 009/2019 Ocie v Ortensia.
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
The dispute between Pearl Petroleum and the KRG thus evolved from a straightforward breach of a hydrocarbon development contract into a complex jurisdictional puzzle. The claimants successfully navigated the substantive hurdle of sovereign immunity by relying on a meticulously drafted contractual waiver and the legal implications of a London arbitral seat. However, their victory was immediately tempered by the rigid procedural realities of cross-border service under the Riyadh Convention. The KRG's tactical pivot from substantive immunity to procedural obstruction underscores the reality that in high-stakes energy arbitration against sovereign states, securing a multi-billion-dollar award is only the prologue to a grueling enforcement saga.
How Did the Case Move From Ex Parte Application to Final Hearing?
The procedural trajectory of Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003 exposes a fundamental friction in transnational arbitration enforcement: the claimant’s imperative for immediate, unnotified recognition versus a sovereign defendant’s fundamental right to proper service and jurisdictional challenge. The dispute, stemming from a contract executed On 4 April 2007, involved staggering sums, with the unpaid portions of the arbitral awards amounting to over USD 2 billion. Faced with a sovereign debtor and the inherent risks of asset dissipation, the Claimants—Pearl Petroleum Company Limited, Dana Gas PJSC, and Crescent Petroleum Company International Limited—initiated enforcement proceedings through an aggressive, unnotified legal strike.
The Court granted an ex parte recognition order on May 29, 2017. Justice Sir Jeremy Cooke issued the order ex parte on 29 May 2017, formally recognising the two London Court of International Arbitration (LCIA) awards. The mechanics of the ex parte application relied heavily on the Rules of the DIFC Courts (RDC), which structurally accommodate unnotified recognition to secure the jurisdiction and prevent a debtor from restructuring assets prior to enforcement. Justice Cooke found the ex parte approach entirely appropriate, even against a state entity, grounding his decision in established common law principles.
There is in my judgment, no objection to the granting of the ex parte order for recognition of the Award since this is the procedure provided in the RDC and there is authority in both England and Australia that this is justifiable where the debtor under the Award is a state.
The Claimants' strategy extended beyond mere recognition. Anticipating severe logistical and diplomatic hurdles in formally serving the Kurdistan Regional Government (KRG) within the Federal Republic of Iraq, the Claimants simultaneously sought and obtained an order for alternative service. This order permitted the Claimants to serve the recognition order and associated documents on the KRG’s London solicitors, Addleshaw Goddard, who had represented the sovereign entity during the underlying LCIA arbitration. The rationale for such an order typically hinges on a defendant's evasive conduct or the practical impossibility of standard service methods. Justice Cooke articulated the underlying policy of the RDC provisions governing alternative service:
The clear intention of the alternative service provisions is to cater for the situation where a party is obstructing service and to do so whether the defendant in question resides in or outside the court’s territorial jurisdiction.
The ex parte mechanism, while robust, is inherently provisional. It serves as a jurisdictional gateway rather than a final determination, shifting the burden to the defendant to contest the order once notified. As explored in ARB 009/2019 Ocie v Ortensia, the integrity of ex parte recognition relies entirely on the subsequent opportunity for the respondent to mount a defence. The initial lack of notice must be cured by a rigorous right of reply. Justice Cooke explicitly acknowledged this procedural safeguard, noting the mandatory transition from unnotified recognition to adversarial scrutiny.
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
The KRG did not remain passive. The KRG applied on July 3, 2017, to set aside the recognition and the alternative service order. Once notified via their London counsel, the sovereign defendant initiated a calculated counter-offensive, filing an application to dismantle the procedural architecture the Claimants had constructed. The timeline reveals a rapid escalation from the initial ex parte grant to a full-throated adversarial clash.
The July 3 application attacked the alternative service order directly, arguing that the DIFC Courts could not bypass mandatory international treaty obligations via domestic procedural rules. The KRG contended that service upon a foreign state entity required strict adherence to the Riyadh Convention, a multilateral treaty governing judicial cooperation to which both the United Arab Emirates and Iraq are signatories. By permitting service on London solicitors, the KRG argued, the Court had circumvented the exclusive, treaty-prescribed diplomatic channels required for serving a sovereign entity in Iraq.
The procedural escalation continued two weeks later. A subsequent application on July 17, 2017, challenged the Court's jurisdiction entirely. The KRG applied on 17 July 2017 to set aside the enforcement proceedings on the fundamental ground of state immunity. The KRG asserted that as a constituent region of the Federal Republic of Iraq, it was immune from the adjudicative and enforcement jurisdiction of the DIFC Courts. This dual-track challenge—attacking both the method of service and the underlying jurisdiction—forced the Court to confront the absolute limits of its supervisory and enforcement powers.
The Claimants countered the jurisdictional challenge by relying on the KRG's explicit contractual waiver of immunity. The 2007 agreement contained a clause stating that the KRG waived any claim to immunity for itself and its assets. The Court had to determine whether this commercial waiver extended to enforcement proceedings in a foreign jurisdiction like the DIFC. Justice Cooke found that the agreement to arbitrate carried inherent waivers regarding supervisory and enforcement jurisdiction.
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
Furthermore, the KRG's jurisdictional challenge required the Court to interpret the interplay between the LCIA arbitration agreement and the enforcement forum. By agreeing to London as the arbitral seat, the KRG had submitted to English supervisory jurisdiction. The translation of that submission to DIFC enforcement proceedings remained fiercely contested, but the prior rulings of the English courts on the same arbitration provided a powerful anchor for the Claimants. Justice Cooke noted the preclusive effect of these prior English decisions on the KRG's arguments.
Their view accords with my own in any event but, in my judgement, therefore, the decisions of the English Courts do create an issue estoppel against the Defendant in raising the argument that the waiver is insufficient where recognition, enforcement and execution are concerned.
37.
The tension between the ex parte recognition and the KRG's right to challenge service culminated in the final Hearing: 8-9 August 2017. The Court had to untangle whether the Riyadh Convention applied to the service of an enforcement order, as opposed to the enforcement of a judgment itself. The Claimants argued that the Riyadh Convention was inapplicable because they were not seeking to enforce a DIFC judgment in Iraq; rather, they were seeking to enforce an arbitral award within the DIFC against KRG assets located there. Justice Cooke analysed the specific wording of the treaty obligations binding the DIFC.
Under the express terms of Article 42, the DIFC must comply with the terms of an applicable treaty for the mutual enforcement of judgements, orders and awards. The Riyadh Convention is a treaty for the mutual enforcement of judgements but in my view, it is not an applicable treaty for this purpose, since neither the Claimant, the DIFC Courts nor the UAE is seeking to enforce a judgment in Iraq, at least at this stage.
Despite finding that the Riyadh Convention did not govern the enforcement of the award in the DIFC, the Court ultimately concluded that the Convention did govern the service of the judicial documents initiating that enforcement against a party in Iraq. The mandatory nature of the treaty's service provisions could not be overridden by the RDC's alternative service rules.
The procedural history of Pearl Petroleum v KRG serves as a masterclass in the strategic deployment of ex parte applications and the subsequent defensive maneuvers available to sovereign entities. The Claimants successfully secured the initial recognition, establishing a critical jurisdictional foothold and satisfying the threshold for potential asset-freezing measures.
Without descending into any detail on this, I am satisfied that the lower threshold for an application for disclosure, namely of credible grounds for making an application for a freezing injunction, is met.
However, the KRG's aggressive and layered applications on July 3 and July 17 effectively neutralised the alternative service order. By successfully arguing that alternative service on London solicitors violated the Riyadh Convention, the KRG forced the Claimants to navigate the rigid, time-consuming requirements of diplomatic service for actual notification. The transition from the May 29 ex parte order to the August final hearing illustrates the delicate balance the DIFC Courts must strike: facilitating swift, unnotified enforcement to protect arbitral awards, while rigorously protecting a sovereign defendant's procedural rights under mandatory international treaties. An ex parte recognition order is only as robust as the service mechanism that follows it, and domestic procedural expediency cannot cure a fundamental defect in international service.
What Is the Scope of Sovereign Immunity Waiver in Commercial Contracts?
When a state entity enters into a high-stakes commercial agreement, the inclusion of an arbitration clause and a waiver of sovereign immunity is standard practice, designed to give private investors confidence that their contractual rights are enforceable. Yet, when disputes crystallise into multi-billion-dollar liabilities, state organs frequently attempt to resurrect the shield of immunity to block the recognition and execution of arbitral awards. In Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003, the Dubai International Financial Centre (DIFC) Court of First Instance confronted this exact dynamic. Facing the enforcement of LCIA awards where over USD 2 billion remained unpaid, the Kurdistan Regional Government of Iraq (KRG) argued that the DIFC Courts lacked jurisdiction to enforce the awards against a sovereign entity.
The dispute originated from an agreement executed On 4 April 2007 between the KRG and Dana Gas PJSC, which was subsequently assigned in parts to Crescent Petroleum Company International Limited and ultimately to Pearl Petroleum Company Limited. The contract, governed by English law, contained a multi-tiered dispute resolution clause culminating in LCIA arbitration seated in London. Crucially, The 23rd bullet point of Annexure 2 to the Contract contained an explicit concession: "the KRG waives on its own behalf and that of the KRG any claim to immunity for itself and its assets." Despite this seemingly unambiguous language, the KRG sought to challenge the scope and applicability of the waiver during the enforcement proceedings in Dubai.
Justice Sir Jeremy Cooke’s analysis of the immunity defence required a fundamental classification of sovereign immunity within the DIFC’s legal architecture. The KRG’s counsel attempted to argue that the DIFC Court should decline to decide issues of state immunity entirely, suggesting that the doctrine's existence, ambit, and any purported waiver were matters of statecraft rather than strict law. The Court firmly rejected this premise. Justice Cooke determined that the issue of state or sovereign immunity is a question of procedural law in itself. By framing immunity as a procedural mechanism rather than an unassailable political absolute, the Court situated the dispute firmly within its own jurisdictional competence.
The Court drew a sharp distinction between the diplomatic recognition of a state and the legal adjudication of a state entity's commercial obligations. While acknowledging that whether the United Arab Emirates recognises another state may be a matter of its foreign policy, the Court held that the legal consequences of an entity's actions—specifically its exercise of sovereign powers or its status as a constituent arm of the state—are matters for the judiciary to resolve. In the context of arbitration, the enforcement of an award against a state entity that has waived its immunity is not an infringement on sovereignty; rather, it is the enforcement of consensual obligations undertaken in a commercial contractual context.
Having established the Court's competence to adjudicate the waiver, Justice Cooke turned to the mechanics of the arbitration agreement itself. The KRG had not merely signed a standalone waiver; it had agreed to a specific arbitral framework. The choice of London as the seat of arbitration carried profound legal consequences for the scope of the KRG's immunity. By selecting a specific jurisdiction to host the arbitration, a state entity implicitly submits to the supervisory powers of that jurisdiction's courts. Justice Cooke articulated this principle with absolute clarity:
It is clear that the KRG entered into an agreement to arbitrate in London under the auspices of the LCIA and that in agreeing to London as the seat of the Arbitration, it also agreed to the English Court as the supervisory court.
This submission to the supervisory court is not a mere procedural formality; it is a substantive waiver of immunity regarding the mechanisms required to support and enforce the arbitral process. The KRG's agreement to arbitrate in London meant that it had accepted the application of the English Arbitration Act 1996 to the proceedings. Consequently, the waiver of immunity extended to the statutory powers granted to the English courts to oversee the arbitration and, critically, to enforce the resulting awards. Justice Cooke expanded on the necessary implications of this contractual choice:
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
Section 66 of the English Arbitration Act provides the mechanism by which an arbitral award may be enforced in the same manner as a judgment or order of the court. By finding that the KRG's waiver inherently covered Section 66 powers, the DIFC Court confirmed that a waiver of immunity for arbitration is not limited to the arbitral hearings themselves but encompasses the judicial architecture required to give the award legal teeth.
This robust interpretation of the waiver aligns with the DIFC's broader jurisprudential trajectory regarding arbitration enforcement. The DIFC Courts have consistently positioned themselves as a reliable conduit for the recognition and enforcement of arbitral awards, a stance cemented in cases such as ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC [2013] DIFC ARB 003. In Banyan Tree, the Court confirmed its jurisdiction to recognise awards even absent assets within the DIFC, establishing the Centre as a primary enforcement gateway. In Pearl Petroleum, the Court applied a similarly commercially pragmatic approach to state immunity, ensuring that sovereign entities cannot utilise the DIFC as a safe harbour to evade obligations they have expressly contracted to uphold.
Faced with the reality of the contractual waiver, the KRG attempted a secondary defensive manoeuvre. The KRG argued that even if a waiver existed, it was insufficient to cover the specific acts of recognition, enforcement, and execution. This argument sought to slice the concept of immunity into distinct phases, suggesting that a state might waive immunity from suit (allowing the arbitration to proceed) without waiving immunity from execution (preventing the successful party from actually recovering the awarded sums).
Justice Cooke gave this argument short shrift, relying on the procedural history of the dispute in the English courts. The claimants had already engaged the English judicial system to secure their rights under the LCIA awards, and the English courts had previously scrutinised the exact wording of the KRG's waiver. Because the English courts had already determined the scope and validity of the waiver under the governing law of the contract and the seat of the arbitration, the KRG was legally precluded from re-litigating the issue in Dubai. Justice Cooke deployed the doctrine of issue estoppel to shut down the KRG's collateral attack:
Their view accords with my own in any event but, in my judgement, therefore, the decisions of the English Courts do create an issue estoppel against the Defendant in raising the argument that the waiver is insufficient where recognition, enforcement and execution are concerned.
The application of issue estoppel in this context is a powerful tool for practitioners enforcing awards against recalcitrant state entities. It prevents a sovereign debtor from forcing a successful claimant to prove the validity of an immunity waiver afresh in every jurisdiction where enforcement is sought. Once the supervisory court at the seat of arbitration has definitively ruled on the scope of the waiver, that determination binds the parties in subsequent recognition proceedings before the DIFC Courts.
The ruling in Pearl Petroleum delivers a definitive statement on the durability of sovereign immunity waivers in commercial contracts. The DIFC Court will not entertain attempts by state entities to retroactively narrow the scope of their contractual concessions. When a state organ agrees to institutional arbitration, selects a seat, and signs a broad waiver of immunity for itself and its assets, the Court will interpret that agreement as a comprehensive submission to the entire lifecycle of the arbitral process—from the constitution of the tribunal to the final execution of the award. By treating the waiver as a binding commercial obligation rather than a fluid political courtesy, Justice Cooke reinforced the DIFC's status as a jurisdiction where contractual certainty prevails over sovereign exceptionalism.
Why Is the Riyadh Convention Mandatory for Service of Documents?
The intersection of domestic procedural agility and rigid international treaty obligations frequently generates friction in cross-border enforcement. In Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003, Justice Sir Jeremy Cooke confronted this exact tension. The claimants—Pearl Petroleum Company Limited, Dana Gas PJSC, and Crescent Petroleum Company International Limited—sought to enforce LCIA arbitration awards against the Kurdistan Regional Government of Iraq (KRG). The financial stakes were monumental, as over USD 2 billion (bn), remains unpaid under the awards. Anticipating difficulties in serving a foreign state entity, the claimants initially secured an ex parte order that not only recognised the awards but also permitted alternative service on the KRG’s London-based solicitors.
The strategic logic behind seeking alternative service is familiar to practitioners navigating hostile enforcement environments. When dealing with sovereign or quasi-sovereign entities, traditional service channels can become black holes of diplomatic delay. The Rules of the DIFC Courts (RDC) Part 9 provide mechanisms to bypass such blockages, allowing service through alternative methods when standard procedures are impractical. Justice Sir Jeremy Cooke acknowledged the underlying rationale for these rules, noting the practical realities of international litigation:
The clear intention of the alternative service provisions is to cater for the situation where a party is obstructing service and to do so whether the defendant in question resides in or outside the court’s territorial jurisdiction.
However, the KRG aggressively challenged this procedural shortcut. The procedural history of the challenge is neatly summarised by the Court:
(a) The Defendant (the “
KRG
”) applied on 3 July 2017 to set aside the Order of this Court made ex parte on 29 May 2017 by which it recognised and, subject to its terms, enforced two arbitration awards made in London under the auspices of the LCIA and permitted alternative service of the order made and other documents on the KRG’s London solicitors who had acted for them in the arbitration.
The core of the KRG's procedural defense rested on the Riyadh Arab Agreement for Judicial Cooperation (the Riyadh Convention), a multilateral treaty to which both the United Arab Emirates and the Federal Republic of Iraq are signatories. The KRG advanced the claim that service could only legitimately have been effected under the terms of the Riyadh Convention and not by the Court ordering alternative service. The Convention prescribes an exclusive and mandatory framework for the service of judicial documents between member states, typically requiring transmission through diplomatic channels or designated Ministries of Justice. By serving the KRG's London solicitors, the claimants had entirely bypassed this treaty-mandated architecture.
The Court was thus forced to adjudicate a direct conflict between the RDC's flexible alternative service provisions and the rigid diplomatic channels of the Riyadh Convention. The claimants argued that the DIFC Courts, acting as a supervisory and enforcing jurisdiction, retained the inherent power to regulate their own process, particularly where a defendant might actively evade service. Yet, Justice Sir Jeremy Cooke drew a sharp, fundamental line between the Court's jurisdictional authority to issue an order and the procedural mechanics required to notify the defendant of that order:
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
This distinction is critical to understanding the limits of judicial power in the DIFC. The Court affirmed that the ex parte recognition of the LCIA awards was entirely proper under the RDC. The jurisdictional foundation for the recognition order remained solid, bolstered by the fact that the Contract contained a clause where the KRG waives on its own behalf and that of the KRG any claim to immunity. Because the enforcement of an Award as a result of a waiver of immunity is based on consensual obligations undertaken in a commercial context, the Court possessed the requisite authority to recognize the debt. However, the validity of the service of that order was a separate legal question governed by a different hierarchy of norms.
In resolving the conflict, the Court established unequivocally that treaty obligations override domestic procedural rules regarding alternative service. The Riyadh Convention is not merely a set of optional guidelines or a default mechanism to be discarded when inconvenient; it imposes binding obligations on its signatories under international law. When a treaty dictates specific channels for the transmission of judicial documents between the UAE and Iraq, the DIFC Courts cannot unilaterally authorize a bypass, regardless of how efficient or necessary that bypass might seem in the context of a massive commercial dispute. The Court's intention to prevent obstruction, while valid within the domestic sphere, does not grant it the power to ignore international law.
The ruling dismantled the claimants' alternative service strategy. By setting aside the order for alternative service, the Court forced the claimants to restart the notification process through the formal, treaty-compliant channels. This strict adherence to treaty protocols serves as a vital check on the expansive use of ex parte powers. It ensures that while the DIFC Courts remain a robust forum for enforcement—as seen in foundational cases like ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC—they do not operate in a vacuum devoid of international comity. The DIFC is a common law island, but it remains anchored to the UAE's sovereign treaty commitments.
The decision also clarifies the limits of the DIFC Courts' pro-enforcement philosophy. While the Court is willing to hold state entities to their commercial bargains and enforce waivers of sovereign immunity, it will not compromise on fundamental procedural rights enshrined in international treaties. The requirement for proper service is not a mere technicality; it is the bedrock of due process, ensuring that a defendant has a genuine opportunity to contest an ex parte order. The integrity of the ex parte recognition process, a theme similarly explored in ARB 009/2019 Ocie v Ortensia, depends entirely on the subsequent provision of fair notice in accordance with applicable law.
For practitioners, Pearl Petroleum v KRG delivers a stark warning: domestic procedural agility cannot cure a failure to comply with mandatory international treaties. When enforcing awards against entities located in jurisdictions covered by the Riyadh Convention (or similar multilateral agreements like the GCC Convention), claimants must factor the rigidities of treaty-mandated service into their strategic timelines. Attempting to circumvent these channels via alternative service orders on local or international counsel is a high-risk gamble that is likely to fail upon challenge. The delay inherent in diplomatic service must be priced into the enforcement strategy from day one.
Ultimately, Justice Sir Jeremy Cooke’s judgment strikes a delicate balance. By maintaining the order for recognition and enforcement of the arbitration awards while striking down the alternative service order, the Court preserved the claimants' substantive victory while enforcing strict procedural compliance. The awards themselves, representing massive liabilities for the KRG, remained recognized within the DIFC. Yet, the procedural clock for the KRG to challenge that recognition could only begin ticking once service was effected lawfully under the Riyadh Convention. This bifurcated approach reinforces the DIFC Courts' sophisticated understanding of their dual role: acting as a commercial court of global standing while remaining a faithful organ of the UAE judicial system bound by its international commitments.
How Did Justice Sir Jeremy Cooke Reach the Decision?
Justice Sir Jeremy Cooke faced a complex matrix of international arbitration law, state immunity defenses, and cross-border service treaties when untangling the procedural knot presented by the Kurdistan Regional Government (KRG). The claimants—Pearl Petroleum Company Limited, Dana Gas PJSC, and Crescent Petroleum Company International Limited—sought to enforce London Court of International Arbitration (LCIA) awards where over USD 2 billion remained unpaid. The KRG’s defensive strategy relied on a dual application: first, to strike down the recognition order on jurisdictional and sovereign immunity grounds, and second, to invalidate the method by which that order was served.
The resulting judgment demonstrates a rigorous application of both English arbitration law and DIFC procedural rules, carefully bifurcating the substantive right to recognize an arbitral award from the procedural mechanics required to notify a foreign state entity.
The analysis began with the KRG’s application to set aside the initial recognition order, which had been granted ex parte on 29 May 2017. The KRG argued that as a constituent region of the Federal Republic of Iraq, it was entitled to sovereign immunity, thereby stripping the DIFC Courts of jurisdiction to recognize the awards. Justice Cooke dismantled this defense by examining the underlying commercial agreement. The contract between the parties explicitly stated that the KRG waives on its own behalf any claim to immunity for itself and its assets.
For Justice Cooke, the waiver was not merely a contractual formality; it was a foundational submission to the supervisory and enforcement architecture of the chosen arbitral seat. By agreeing to arbitrate in London under LCIA rules, the KRG had implicitly accepted the enforcement mechanisms that naturally flow from such an agreement.
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
This finding firmly established that the enforcement of an arbitral award against a state entity, following a clear waiver of immunity, is grounded in consensual obligations undertaken in a commercial contractual context. The court treated the KRG not as an untouchable sovereign acting in a public capacity, but as a commercial actor bound by its own contractual concessions.
Having dispensed with the sovereign immunity objection, Justice Cooke addressed the propriety of granting the recognition order on an ex parte basis. In international arbitration enforcement, ex parte recognition is a standard procedural tool designed to secure the debtor's assets before they can be dissipated. However, the KRG argued that deploying this mechanism against a state entity was inappropriate and jurisdictionally flawed. Justice Cooke rejected this premise, aligning the DIFC’s approach with established common law jurisdictions.
There is in my judgment, no objection to the granting of the ex parte order for recognition of the Award since this is the procedure provided in the RDC and there is authority in both England and Australia that this is justifiable where the debtor under the Award is a state.
This ruling affirmed the validity of ex parte recognition for state-debtors, signaling to practitioners that the DIFC Courts will not dilute their pro-enforcement stance simply because the respondent is a governmental body. The procedural rules of the DIFC Courts (RDC) apply with equal force to commercial entities and state actors who have waived their immunity. The integrity of the ex parte process, a recurring theme in DIFC jurisprudence as seen in cases like ARB 009/2019 Ocie v Ortensia, relies on the court's ability to act swiftly while preserving the respondent's right to challenge the order after the fact.
This brought Justice Cooke to the critical distinction at the heart of the judgment: the difference between the validity of the recognition order itself and the validity of the method used to serve it. While the court possessed the unquestionable authority to recognize the award ex parte, the subsequent notification of that order to the KRG had to comply with strict legal frameworks.
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
The claimants, anticipating difficulties in serving a foreign government entity in Iraq, had successfully applied for an order permitting alternative service. This order allowed them to serve the recognition documents on the KRG’s London solicitors, who had represented the government during the LCIA arbitration. Under standard commercial circumstances, such an order is a routine application of the RDC, designed to prevent evasive respondents from frustrating enforcement.
The clear intention of the alternative service provisions is to cater for the situation where a party is obstructing service and to do so whether the defendant in question resides in or outside the court’s territorial jurisdiction.
However, the KRG was not a standard commercial respondent, and the geographical realities of the dispute invoked higher-order legal obligations. Both the United Arab Emirates and the Federal Republic of Iraq are signatories to the Riyadh Convention, a multilateral treaty governing judicial cooperation and the service of legal documents among Arab League states.
Justice Cooke undertook a rigorous statutory analysis of the interplay between the DIFC’s domestic procedural rules and the UAE’s international treaty commitments. He concluded that the Riyadh Convention provides a mandatory, exclusive framework for the transmission of judicial documents between the UAE and Iraq. The DIFC Courts, as an organ of the Dubai judicial system, cannot utilize the RDC's alternative service provisions to bypass the diplomatic and judicial channels mandated by a binding international treaty.
The claimants' attempt to serve the KRG's London solicitors, while practically efficient, was legally fatal to the service process. The alternative service order was fundamentally incompatible with the Riyadh Convention's requirements. Consequently, Justice Cooke struck down the alternative service order, ruling that the claimants must effect service through the proper treaty mechanisms.
Yet, in a display of judicial pragmatism, Justice Cooke refused to throw the baby out with the bathwater. The KRG had argued that the failure of service should result in the complete nullification of the enforcement proceedings. The court rejected this maximalist position. The invalidity of the service method did not retroactively infect the court's jurisdiction to issue the underlying recognition order. The ex parte order recognizing the LCIA awards remained entirely valid; it simply remained unserved in the eyes of the law.
This bifurcated outcome reflects a highly sophisticated approach to maintaining the integrity of the arbitral process. By upholding the recognition order, Justice Cooke preserved the claimants' substantive rights and the legal status of the LCIA awards within the DIFC. By striking down the alternative service order, he enforced strict compliance with international treaty obligations, ensuring that the DIFC Courts operate within the boundaries of the UAE's diplomatic commitments. The judgment forces practitioners to recognize that while the DIFC offers robust, pro-arbitration enforcement mechanisms, those mechanisms cannot be weaponized to circumvent mandatory international law.
Which Earlier DIFC Cases Frame This Decision?
Justice Sir Jeremy Cooke’s judgment in Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003 does not exist in a procedural vacuum. It represents a critical node in a well-established line of jurisprudence defining the Dubai International Financial Centre (DIFC) Courts' supportive posture toward international arbitration. The ruling addresses the enforcement of two London Court of International Arbitration (LCIA) awards exceeding USD 2 billion. By upholding the recognition of these awards while simultaneously striking down an order for alternative service, the Court navigated the complex tension between robust arbitral enforcement and strict procedural compliance. This delicate balancing act relies heavily on foundational principles established in earlier DIFC authorities, particularly concerning the enforcement of foreign-seated awards, the procedural mechanics of ex parte recognition, and the limits of sovereign immunity in commercial contexts.
The procedural starting point for the claimants—Pearl Petroleum Company Limited, Dana Gas PJSC, and Crescent Petroleum Company International Limited—was an ex parte application to recognise and enforce the LCIA awards. The Kurdistan Regional Government (KRG) aggressively challenged this, arguing against the jurisdiction of the DIFC Courts and the ex parte nature of the initial order. However, the DIFC Courts have long maintained that ex parte recognition is not merely permissible but is the standard procedural route under the Rules of the DIFC Courts (RDC), even when the respondent is a foreign state entity. Justice Sir Jeremy Cooke affirmed this procedural norm, aligning the DIFC's approach with broader common law practices and rejecting the notion that sovereign status necessitates a departure from standard enforcement mechanics.
There is in my judgment, no objection to the granting of the ex parte order for recognition of the Award since this is the procedure provided in the RDC and there is authority in both England and Australia that this is justifiable where the debtor under the Award is a state.
This firm stance on ex parte recognition, and the subsequent burden placed on the defendant to apply to set it aside, echoes the foundational principles laid down in ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC [2013] DIFC ARB 003. In Banyan Tree, the DIFC Courts confirmed their expansive jurisdiction to recognise and enforce arbitral awards irrespective of whether the award debtor possessed assets within the DIFC at the time of the application. The Pearl Petroleum decision builds directly upon this doctrine by confirming that the procedural mechanism for such recognition—the ex parte order—remains robust and applicable even when sovereign immunity is invoked as a shield. The Court's logic dictates that the initial recognition is an administrative and procedural step, shifting the battleground to the subsequent application to set aside, provided service is validly effected. As the Court noted, the Court had jurisdiction to make the order ex parte but the order then had to be formally served to allow the defendant the statutory opportunity to challenge its validity.
The enforcement of foreign-seated awards is another critical area where Pearl Petroleum draws heavily on the DIFC's doctrinal lineage. The arbitration awards in question were seated in London, making the English High Court the primary supervisory jurisdiction. The KRG attempted to argue that the DIFC Courts lacked the jurisdictional mandate to enforce these foreign awards against a sovereign entity. The DIFC Courts, however, have consistently positioned themselves as a reliable conduit for the enforcement of international awards, a principle solidified in cases like ARB-001-2014: (1) Fiske (2) Firmin v (1) Firuzeh. In Fiske, the Court emphasised its autonomous jurisdiction to enforce awards under the DIFC Arbitration Law, operating independently of the onshore Dubai courts' procedures and resisting attempts to import onshore procedural hurdles into the offshore jurisdiction.
In Pearl Petroleum, Justice Sir Jeremy Cooke extended this logic to the highly contested realm of state immunity. By agreeing to arbitrate in London under the LCIA rules, the KRG was deemed to have waived its immunity not just in the supervisory court, but also in enforcing courts globally, including the DIFC. The act of entering into a commercial contract containing a binding arbitration clause is treated by the DIFC Courts as a definitive and irrevocable waiver of procedural immunities regarding the enforcement of the resulting award.
It is clear that the KRG entered into an agreement to arbitrate in London under the auspices of the LCIA and that in agreeing to London as the seat of the Arbitration, it also agreed to the English Court as the supervisory court.
The Court further elaborated that this waiver extended comprehensively to the exercise of supervisory and enforcement powers. By submitting to the jurisdiction of the English courts for supervisory purposes, the KRG implicitly accepted the international enforcement regime that inevitably follows such an award. The judgment explicitly states that it was inherent in that agreement that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under section 66 of the English Arbitration Act. This contractual waiver is a cornerstone of the DIFC's approach to state entities engaging in commercial arbitration, ensuring that sovereign immunity cannot be weaponised post-award to defeat legitimate enforcement efforts. The Court treated the enforcement of an Award as a result of a waiver of immunity as fundamentally based on consensual obligations undertaken in a commercial contractual context, stripping away the sovereign veil when the state acts as a commercial actor.
The decision also reinforces the DIFC's unwavering commitment to the standards of the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. The DIFC Arbitration Law is modelled on the UNCITRAL Model Law and explicitly incorporates the New York Convention's pro-enforcement bias. The KRG sought to complicate this straightforward enforcement narrative by invoking the Riyadh Arab Agreement for Judicial Cooperation (the Riyadh Convention), arguing that its strict provisions on the service of judicial documents between Arab states should override the DIFC's standard procedures or any alternative service orders granted by the Court.
Justice Sir Jeremy Cooke carefully delineated the boundaries between these overlapping international instruments. While acknowledging the mandatory nature of the Riyadh Convention for the service of documents between the UAE and Iraq, the Court refused to allow this procedural requirement to derail the underlying recognition of the arbitral award itself. The Court clarified the specific application of the Riyadh Convention in the context of the DIFC's broader treaty obligations.
Under the express terms of Article 42, the DIFC must comply with the terms of an applicable treaty for the mutual enforcement of judgements, orders and awards. The Riyadh Convention is a treaty for the mutual enforcement of judgements but in my view, it is not an applicable treaty for this purpose, since neither the Claimant, the DIFC Courts nor the UAE is seeking to enforce a judgment in Iraq, at least at this stage.
This distinction is analytically crucial. The Court maintained the ex parte recognition order because the act of recognition within the DIFC jurisdiction does not equate to enforcing a judgment in Iraq, which would trigger the specific mutual enforcement mechanisms of the Riyadh Convention. However, the Court did concede that the physical service of the DIFC order on the KRG in Iraq had to comply strictly with the Riyadh Convention's procedural requirements for state-to-state transmission. Consequently, the Court struck down the previously granted order for alternative service. The claimants had sought to serve the KRG's London solicitors, arguing that the KRG was actively evading service and frustrating the enforcement process. The Court acknowledged the practical utility of alternative service, noting that the clear intention of the alternative service provisions is to cater for situations where a party is obstructing service, regardless of whether the defendant resides inside or outside the court’s territorial jurisdiction. Yet, the mandatory language of the Riyadh Convention regarding diplomatic service channels could not be bypassed by the RDC's domestic alternative service rules.
The resulting judgment is a masterclass in judicial precision and jurisdictional boundary-setting. By upholding the recognition order while quashing the alternative service order, Justice Sir Jeremy Cooke reaffirmed the DIFC Courts' pro-arbitration stance without overstepping binding international treaty obligations. The claimants retained their recognised awards, securing their position within the DIFC, but were forced to navigate the formal diplomatic channels for service mandated by the Riyadh Convention to progress to actual execution.
Ultimately, Pearl Petroleum v KRG serves as a definitive guide for practitioners handling high-value, cross-border enforcement actions involving state entities. It confirms that the DIFC Courts will not hesitate to grant ex parte recognition of foreign awards, relying heavily on the contractual waiver of immunity inherent in the agreement to arbitrate. However, it also serves as a stark warning that procedural shortcuts, such as alternative service on foreign solicitors, will not be tolerated when mandatory international treaties dictate otherwise. The fundamental requirement that the order then has to be served in order to give the defendant the opportunity to challenge it remains an unshakeable pillar of due process, ensuring that the DIFC's robust enforcement regime is continuously balanced by rigorous procedural fairness and treaty compliance.
What Does This Mean for Practitioners and Enforcement Strategies?
Enforcing a high-value arbitral award against a sovereign entity requires navigating a complex matrix of procedural rules, diplomatic protocols, and international treaties. When the sums involved are staggering—in this instance, where over USD 2 billion (bn), remains unpaid—the strategic choices made by counsel regarding service of process can dictate the trajectory of the entire enforcement campaign. Justice Sir Jeremy Cooke’s judgment in Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003 exposes a critical vulnerability in standard enforcement playbooks: the reliance on domestic alternative service mechanisms when mandatory international treaties dictate otherwise. Counsel must prioritize treaty-compliant service when dealing with state entities to avoid severe procedural setbacks.
The procedural architecture of the Dubai International Financial Centre (DIFC) Courts offers robust tools for award creditors, notably the ability to secure ex parte recognition of arbitral awards. This initial step allows creditors to crystallize the award into a local judgment without immediately alerting the debtor, thereby preserving the element of surprise for subsequent asset-freezing applications. However, securing the ex parte order is merely the first phase; the jurisdictional validity of the enforcement action ultimately hinges on effecting valid service upon the respondent. When the respondent is a foreign state or a constituent region of the Federal Republic of Iraq, the mechanics of service transcend the Rules of the DIFC Courts (RDC) and enter the realm of public international law.
Faced with the prospect of navigating notoriously slow diplomatic channels to serve the Kurdistan Regional Government (KRG), the claimants in Pearl Petroleum sought a procedural shortcut. They applied for and obtained an order permitting alternative service on the KRG’s English legal representatives. The KRG swiftly challenged this maneuver:
(a) The Defendant (the “
KRG
”) applied on 3 July 2017 to set aside the Order of this Court made ex parte on 29 May 2017 by which it recognised and, subject to its terms, enforced two arbitration awards made in London under the auspices of the LCIA and permitted alternative service of the order made and other documents on the KRG’s London solicitors who had acted for them in the arbitration.
The claimants' strategy was grounded in a well-established commercial litigation tactic. Alternative service is routinely deployed to bypass evasive defendants or to expedite proceedings where traditional service methods are impractical. Justice Cooke acknowledged the fundamental utility of this procedural tool within the DIFC's framework:
The clear intention of the alternative service provisions is to cater for the situation where a party is obstructing service and to do so whether the defendant in question resides in or outside the court’s territorial jurisdiction.
Despite the clear intention behind the RDC's alternative service provisions, Justice Cooke identified a fatal jurisdictional flaw in their application to the KRG. The United Arab Emirates and the Federal Republic of Iraq are both signatories to the Riyadh Arab Agreement for Judicial Cooperation (the Riyadh Convention). The Convention establishes a mandatory, exclusive framework for the transmission and service of judicial documents between member states, typically requiring routing through the respective Ministries of Justice.
The DIFC Courts, while operating as an English-language common law jurisdiction, remain constituent courts of the Emirate of Dubai and, by extension, the UAE. They are unequivocally bound by the UAE's international treaty obligations. By attempting to serve the KRG via its London solicitors, the claimants effectively bypassed the mandatory diplomatic channels prescribed by the Riyadh Convention. Justice Cooke ruled that domestic procedural rules—even those as flexible as the RDC provisions on alternative service—cannot override binding international treaty obligations. Consequently, the alternative service order was struck down.
For practitioners, the immediate strategic takeaway is that alternative service is not a panacea for treaty-governed jurisdictions. When enforcing against entities located in states that share a judicial cooperation treaty with the UAE, counsel must meticulously map the treaty's service requirements before initiating enforcement proceedings. Relying on the RDC's alternative service rules to circumvent a treaty is a false economy. It inevitably results in wasted costs, delayed enforcement, and the necessity of restarting the service process through the correct, albeit slower, diplomatic channels.
Crucially, however, the failure of the alternative service mechanism did not vitiate the entire enforcement effort. Justice Cooke drew a sharp, highly consequential distinction between the Court's jurisdiction to grant an ex parte recognition order and the subsequent procedural requirement to serve that order upon the defendant.
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
This bifurcation of jurisdiction and service preserves a vital tactical advantage for award creditors. It confirms that claimants can validly secure the recognition of an award—and potentially apply for interim relief, such as freezing injunctions—before the defendant is formally notified through cumbersome treaty channels. The threshold for securing such interim protection remains accessible, provided the underlying jurisdictional basis for recognition is sound. Justice Cooke affirmed the availability of these ancillary remedies even while the mechanics of service were being contested:
Without descending into any detail on this, I am satisfied that the lower threshold for an application for disclosure, namely of credible grounds for making an application for a freezing injunction, is met.
The procedural friction encountered in Pearl Petroleum underscores a critical vulnerability that must be addressed at the transactional stage. When drafting arbitration agreements with state entities, counsel must anticipate the complexities of cross-border enforcement. Relying on default treaty mechanisms for service guarantees delay. Instead, parties should explicitly draft bespoke service mechanisms into the arbitration agreement itself, such as appointing a specific, irrevocable agent for service of process located within the enforcing jurisdiction (e.g., a law firm situated in the DIFC).
Furthermore, a robust arbitration agreement with a sovereign must include an unequivocal, comprehensive waiver of state immunity. The KRG attempted to argue that the DIFC Court should not even entertain the enforcement proceedings, asserting sovereign immunity. Justice Cooke rejected this, holding that the issue of state or sovereign immunity is a question of procedural law and that the enforcement of an Award as a result of a waiver of immunity is based on consensual obligations undertaken in a commercial context. The contract contained a specific clause stating that the KRG waives on its own behalf and that of the KRG any claim to immunity. The Court found this waiver to be comprehensive:
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
The strict adherence to treaty obligations demonstrated in Pearl Petroleum provides an instructive contrast to the DIFC Courts' approach in cases involving purely commercial entities attempting to evade enforcement. For instance, in ARB-005-2016: Georgia Corporation v Gavino Supplies [2016] DIFC ARB 005, the Court demonstrated a robust willingness to cut through bad-faith procedural obstructionism where no overriding international treaties were at play. In purely commercial disputes, alternative service remains a highly effective weapon against evasive tactics. However, Pearl Petroleum establishes a hard boundary: perceived obstruction or the desire for expediency cannot be cured by alternative service if a mandatory international treaty dictates the method of service between the relevant states.
Enforcement against sovereign entities in the DIFC requires a meticulously calibrated, dual-track strategy. Counsel must aggressively pursue ex parte recognition and interim relief to secure the jurisdictional foothold and protect assets, while simultaneously initiating the often-plodding, treaty-compliant service mechanisms required by instruments like the Riyadh Convention. Attempting to fast-track service through domestic alternative service rules in the face of a mandatory treaty is a strategic error that invites jurisdictional challenges and protracted satellite litigation. The DIFC Courts remain a formidable, pro-enforcement forum for arbitral awards against states, but they demand absolute fidelity to the UAE's international treaty commitments. Practitioners who fail to respect the hierarchy between domestic procedural rules and international treaties do so at their peril.
What Issues Remain Unresolved Regarding State Enforcement?
The intersection of sovereign immunity and the enforcement of arbitral awards continues to evolve in the DIFC, exposing a persistent friction between international commercial obligations and the procedural shields available to state entities. In Pearl Petroleum Company Limited & Others v The Kurdistan Regional Government of Iraq [2017] DIFC ARB 003, Justice Sir Jeremy Cooke confronted this tension directly, navigating a dispute where over USD 2 billion (bn), remains unpaid under London Court of International Arbitration (LCIA) awards. While the DIFC Court of First Instance readily affirmed its jurisdiction to recognise the awards, the mechanics of bringing a sovereign entity before the court revealed significant unresolved complexities that will dictate the strategy of award creditors for years to come.
The initial procedural posture of the case highlights the DIFC Courts' robust approach to the recognition of arbitral awards, even when the respondent is a foreign state or a constituent region thereof. The claimants secured an initial victory when the court granted recognition without requiring prior notice to the Kurdistan Regional Government (KRG). Justice Sir Jeremy Cooke firmly anchored this approach in the Rules of the DIFC Courts (RDC) and broader common law jurisprudence, noting the established precedent for such unilateral applications:
There is in my judgment, no objection to the granting of the ex parte order for recognition of the Award since this is the procedure provided in the RDC and there is authority in both England and Australia that this is justifiable where the debtor under the Award is a state.
However, the transition from an ex parte recognition to an adversarial enforcement proceeding requires valid service of process—a requirement that transforms a straightforward administrative exercise into a diplomatic and procedural minefield. The court acknowledged that while the initial jurisdiction to recognise the award is broad, the fundamental right of a sovereign defendant to challenge that recognition cannot be bypassed. The procedural sequence is strict:
The Court has jurisdiction to make the order ex parte but the order then has to be served in order to give the defendant the opportunity to apply to set it aside.
The claimants, anticipating the difficulties of serving a foreign governmental entity through traditional diplomatic channels, had obtained an order for alternative service, directing the documents to the KRG’s London solicitors who had acted in the underlying LCIA arbitration. The RDC explicitly contemplates such workarounds to prevent evasive respondents from frustrating the enforcement of valid judgments and awards. Justice Sir Jeremy Cooke articulated the policy rationale behind these rules:
The clear intention of the alternative service provisions is to cater for the situation where a party is obstructing service and to do so whether the defendant in question resides in or outside the court’s territorial jurisdiction.
Despite this clear policy intention, the alternative service order was ultimately struck down, exposing a critical vulnerability in the DIFC's enforcement architecture when dealing with regional states. The fatal flaw was the Riyadh Arab Agreement for Judicial Cooperation (the Riyadh Convention), to which both the United Arab Emirates and the Federal Republic of Iraq are signatories. The treaty mandates specific, formal channels for the transmission of judicial documents between member states. The DIFC Court determined that its local procedural rules regarding alternative service could not override the mandatory international obligations enshrined in the Riyadh Convention.
Future cases will likely test the limits of the Riyadh Convention in the context of modern digital service. As commercial disputes increasingly rely on electronic communication and virtual arbitration, the rigid, paper-based diplomatic channels mandated by mid-20th-century treaties appear increasingly anachronistic. Award creditors facing sovereign debtors within the Riyadh Convention bloc are left in a precarious position: they possess valid, recognised awards but must rely on the bureaucratic machinery of the very state they are attempting to enforce against to effect service. If a state entity chooses to obstruct the diplomatic transmission of service documents, the creditor's enforcement campaign can be indefinitely stalled, regardless of the RDC's provisions against obstruction.
Beyond the immediate hurdle of service, the extent to which execution can be levied against state assets remains a complex area. The KRG applied on 3 July 2017 to set aside the enforcement proceedings, invoking sovereign immunity. The court's rejection of this defense relied heavily on the express terms of the underlying 4 April 2007 contract, wherein the KRG explicitly waives on its own behalf and that of the KRG any claim to immunity for itself and its assets. The court found that agreeing to an English-seated arbitration carried inherent waivers regarding supervisory and enforcement jurisdiction:
It was inherent in that agreement, in my judgment, that the KRG waived any immunity from the exercise of the Court’s supervisory powers under English law and its powers under s 66 of the English Arbitration Act.
The DIFC Court treated the waiver of immunity not as a matter of high statecraft, but as a binding commercial commitment. Justice Sir Jeremy Cooke noted that the enforcement of an Award as a result of a waiver of immunity is based on consensual obligations undertaken in a commercial contractual context. Furthermore, the court deferred to the English courts' prior rulings on the same contract, preventing the KRG from re-litigating the scope of its waiver:
Their view accords with my own in any event but, in my judgement, therefore, the decisions of the English Courts do create an issue estoppel against the Defendant in raising the argument that the waiver is insufficient where recognition, enforcement and execution are concerned.
Yet, a waiver of immunity from jurisdiction and recognition does not automatically translate into a seamless execution against specific state assets. The distinction between recognising an award and actually seizing sovereign property is profound. While the DIFC Court confirmed that the waiver covered execution in principle, the practical reality of identifying and attaching commercial (non-sovereign) assets belonging to a foreign state within the UAE remains a formidable challenge. The burden falls on the award creditor to prove that targeted assets are in use for commercial purposes, a standard that often requires extensive, and highly contested, disclosure applications.
The procedural friction observed in state enforcement mirrors the difficulties practitioners face when dealing with evasive private commercial actors, though the tools of resistance differ. In cases like ARB-009-2023: ARB 009/2023 Mirifa v (1) Mahur (2) Meison (3) Mepur, private debtors utilize asset concealment and jurisdictional duplication to frustrate enforcement. Sovereign entities, by contrast, leverage the architecture of international law—treaties, diplomatic channels, and residual claims of immunity—to achieve similar delays. Both scenarios demand that the DIFC Courts rigorously police the boundaries of procedural fairness while ensuring that the jurisdiction does not become a safe haven for recalcitrant debtors.
A further unresolved nuance lies in the precise application of the Riyadh Convention to arbitral awards as opposed to foreign court judgments. The KRG argued that the entire enforcement proceeding was flawed under the treaty. Justice Sir Jeremy Cooke drew a sharp distinction between the mutual enforcement of judgments across borders and the local recognition of an arbitral award under the DIFC Arbitration Law:
Under the express terms of Article 42, the DIFC must comply with the terms of an applicable treaty for the mutual enforcement of judgements, orders and awards. The Riyadh Convention is a treaty for the mutual enforcement of judgements but in my view, it is not an applicable treaty for this purpose, since neither the Claimant, the DIFC Courts nor the UAE is seeking to enforce a judgment in Iraq, at least at this stage.
This distinction is critical. It preserves the DIFC's autonomy to recognise international arbitral awards under the New York Convention and its own Arbitration Law without being entirely subsumed by the Riyadh Convention's requirements, except where the physical service of documents across borders is concerned. The court effectively bifurcated the process: the substantive right to recognise the award is governed by the pro-enforcement regime of the DIFC, while the procedural mechanics of notifying a defendant in Iraq are strictly governed by the regional treaty.
The balance between state sovereignty and international commercial obligations remains a dynamic tension. The DIFC Courts have demonstrated a clear willingness to hold state entities to their commercial bargains, refusing to allow sovereign immunity to act as a blanket defense where explicit contractual waivers exist. The court noted that whether the UAE recognises another state may be a matter of its foreign policy, but the legal consequences of a commercial entity exercising sovereign powers fall squarely within the judiciary's remit. However, the strict adherence to treaty-based service requirements ensures that sovereign defendants retain significant procedural leverage. Until bilateral or multilateral treaties are updated to reflect the realities of modern commercial litigation, award creditors must navigate a bifurcated system where substantive commercial rights frequently collide with rigid diplomatic protocols.
