On October 7, 2022, Justice Michael Black delivered a decisive blow to Ledger’s attempt to halt parallel litigation in the Dubai Court of First Instance. In a hearing that lasted only days after the initial ex parte application, the Court rejected the request for an interim anti-suit injunction regarding a construction dispute valued at AED 348,000,000. Justice Black’s order, issued at 3pm, turned on the Claimant’s failure to demonstrate a high degree of probability that the DIFC was the agreed seat of arbitration.
For arbitration counsel and cross-border litigators, this decision serves as a stark reminder that the DIFC Court’s power to restrain foreign proceedings is not a default remedy but an exceptional one, contingent upon the clear establishment of the DIFC as the arbitral seat. When the seat is contested or ambiguous, the DIFC Court will not reflexively intervene in the jurisdiction of the Dubai Courts, prioritizing judicial comity over the convenience of a single forum. The ruling clarifies that without a high degree of probability regarding the seat, the threshold for interference remains effectively insurmountable.
How Did the Dispute Between Ledger and Leeor Arise?
The commercial relationship between Ledger, a prominent developer, and Leeor, a Dubai-based construction contractor, began with a massive infrastructure commitment that ultimately collapsed under the weight of poorly drafted dispute resolution provisions. The underlying project involved the ambitious construction of 123 residential buildings in Dubai, a venture that inherently carried significant technical and financial risks. The genesis of the legal conflict is rooted in the initial contractual framework established between the parties.
In or around September 2015, the parties entered into an agreement wherein the Claimant agreed to pay the Defendant AED 348,000,000 for the Defendant to execute and complete the Project and the remedying of defects.
As is common in high-value construction ventures, the relationship deteriorated over the physical realities of the build. Disagreements surfaced regarding the timeline, the standard to which Leeor was required to execute and complete the Project, and the financial liability for remedying structural or aesthetic defects. However, the substantive construction dispute quickly became secondary to a fierce procedural battle over where, and under what legal regime, those disagreements should be resolved.
The dispute resolution mechanism, embedded in Clauses 67.3 and 67.5 of the Particular Conditions of Contract, represents a textbook example of jurisdictional ambiguity—a recurring pathology in Middle Eastern construction contracts drafted without precise foresight. Clause 67.3 directed that disputes failing amicable settlement should be finally settled under the rules of the DIFC-LCIA. Yet, Clause 67.5 immediately muddied the waters by stipulating that the governing law of the procedure was "the law of United Arab Emirates and of Dubai" and, crucially, that "the place of arbitration shall be Dubai."
This linguistic conflation of "Dubai" (the onshore Emirate) and the "DIFC" (the offshore common law jurisdiction) created a jurisdictional vacuum. When relations broke down entirely, Leeor seized upon this ambiguity. In January 2022, Leeor issued correspondence requesting an amicable settlement meeting and providing formal notice of an intent to commence arbitration. This maneuver appeared designed to satisfy the contractual preconditions to arbitration, projecting an outward willingness to engage with the agreed mechanism.
In reality, Leeor executed a sharp tactical pivot. Rather than initiating the DIFC-LCIA arbitration it had just noticed, Leeor bypassed the arbitral tribunal entirely and started proceedings before the Dubai Court of First Instance in June 2022, registering Case Number
How Did the Case Move From Ex Parte Application to Final Hearing?
The procedural timeline of Ledger v Leeor [2022] DIFC ARB 016 offers a stark illustration of the Dubai International Financial Centre (DIFC) Courts’ rigorous approach to emergency injunctive relief. The sheer velocity of the docket—moving from an urgent, without-notice filing to a fully reasoned refusal in just four days—reveals a judiciary that is highly capable of rapid intervention but deeply skeptical of deploying that power to disrupt parallel onshore proceedings without an ironclad jurisdictional mandate.
The underlying conflict stemmed from a September 2015 construction contract. Ledger, the developer of a massive 123-residential-building tower project in Dubai, engaged Leeor, a Dubai-based construction contractor. The financial stakes were substantial, with Ledger agreeing to pay AED 348,000,000 for the Defendant to execute and complete the Project and to remedy any subsequent defects. The contract contained a multi-tiered dispute resolution clause, culminating in arbitration under the DIFC-LCIA rules, with the place of arbitration designated simply as "Dubai."
The commercial relationship eventually fractured, leading to Leeor issuing correspondence on 18 January 2022 in which Leeor both requested an amicable settlement meeting and gave notice of an intent to commence arbitration. However, Leeor abruptly abandoned the arbitral route. Instead of constituting a tribunal, Leeor initiated proceedings before the Dubai Court of First Instance, Case Number 255 of 2022 on June 14, 2022.
Ledger immediately recognized the threat of parallel litigation bypassing the agreed arbitration mechanism. In response, Ledger submitted its defence in those proceedings on 29 June 2022 raising a jurisdictional challenge before the onshore courts. Yet, as the summer progressed and the onshore litigation advanced, Ledger sought a more aggressive tactical advantage by pivoting to the offshore jurisdiction of the DIFC Courts.
On October 3, 2022, Ledger filed an urgent ex parte application. The claim made on 3 October 2022 without notice sought an interim anti-suit injunction to restrain Leeor from taking any further steps in the Dubai Court of First Instance, including participating in any court-appointed expert processes. Ex parte applications are inherently extraordinary; they ask a judge to deploy the coercive power of the state against a party who has not yet been given an opportunity to be heard. When such an application seeks to halt proceedings in a sister court within the same Emirate, the judicial scrutiny intensifies exponentially.
The DIFC Court accommodated the urgency of the request, scheduling a hearing just three days later. The hearing of this Urgent Application has taken place on 6 October 2022, with Counsel for Ledger arguing that the DIFC Court, acting as the supervisory court of the arbitration, had a duty to protect the arbitral process from onshore interference. Ledger’s strategy relied on securing a temporary freeze of the onshore litigation while a formal jurisdictional battle played out in the DIFC.
Counsel for the Claimant articulated this phased approach clearly during the October 6 hearing:
Ledger submits that the most appropriate way forward is for the DIFC Courts, being the supervisory court under the Arbitration Agreement, to intervene and issue an interim anti-suit injunction until the determination of the Defendant's Part 12 jurisdictional challenge and make any further order at that time if appropriate to do so.
H.E. Justice Michael Black KC did not dispute the theoretical availability of the relief sought. The DIFC Courts possess a well-established statutory arsenal to support arbitration, and Justice Black explicitly confirmed the Court's jurisdiction to issue such injunctions in principle:
I accept Ledger’s submission that this Court has the power to grant interim anti suit injunctions under Articles 10 and 32 of the DIFC Court Law 10 of 2004 in particular in aid of arbitration as contemplated by Article 15 of the DIFC Arbitration Law 1 of 2008.
However, possessing the statutory power to issue an anti-suit injunction and finding the appropriate factual matrix to exercise that power are entirely different matters. The rapid progression from the October 3 filing to the October 6 hearing exposed a fatal vulnerability in Ledger's application: the profound ambiguity of the arbitral seat. Because the contract designated "Dubai" rather than the "DIFC" as the place of arbitration, Ledger faced an uphill battle to convince the Court that it should act as the primary supervisory authority.
Justice Black’s analysis during the hearing cut straight through the procedural maneuvering to the core jurisdictional prerequisite. To justify an ex parte intervention against the Dubai Court of First Instance, Ledger needed to prove more than just a valid arbitration agreement; it needed to prove that the DIFC was the undisputed home of that agreement. The standard applied was exacting:
The question for me therefore is whether I am satisfied that there is a high degree of probability that there is a binding Arbitration Agreement with DIFC as its seat or if the seat is not DIFC whether this is one of those exceptional cases where the Court will nevertheless grant an anti-suit injunction.
Ledger failed to clear this high bar. The contractual language was simply too equivocal to establish a "high degree of probability" that the parties intended the offshore jurisdiction of the DIFC to supervise their arbitration, rather than the onshore jurisdiction of non-DIFC Dubai. Furthermore, Justice Black found no "exceptional circumstances" that would justify the DIFC Court reaching across the jurisdictional divide to restrain a party from accessing the onshore courts.
The refusal was absolute and grounded in a strict interpretation of the evidentiary burden required for emergency relief:
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.
The speed of the Court's final determination matched the urgency of the initial filing. On October 7, 2022, at exactly 3:00 PM—just 24 hours after the hearing concluded—Justice Black issued his formal order refusing the application. The swift turnaround provided immediate certainty to the parties, ensuring that the onshore proceedings were not left in a state of procedural limbo due to an unmeritorious offshore injunction attempt.
Yet, the order was not entirely a dead end for Ledger. Recognizing the complex and evolving interplay between onshore and offshore jurisdictions regarding seat-ambiguous arbitration clauses, Justice Black granted permission to appeal against this Order on the grounds that there is another compelling reason for the appellate court to weigh in. This allowance for an appeal acknowledges that while ex parte emergency relief was inappropriate given the evidentiary gaps, the broader question of how the DIFC Courts should interpret "Dubai" seat clauses remains a matter of significant public interest to the arbitration community.
The trajectory of Ledger v Leeor stands in sharp contrast to cases where the seat is explicitly defined. For instance, in ARB-005-2025: ARB 005/2025 Nashrah v (1) Najem (2) Nex, the DIFC Courts demonstrated a much higher willingness to deploy anti-suit injunctions when their supervisory jurisdiction was unambiguous. The DIFC judiciary is not inherently hostile to anti-suit injunctions; rather, it is fiercely protective of the boundaries of comity. The legacy of ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC established the DIFC as a robust, pro-arbitration conduit jurisdiction, but Ledger defines the outer limits of that doctrine. When a party seeks to weaponize the DIFC Courts' emergency procedures to halt onshore litigation without a clear contractual mandate, the Court will move swiftly—not to grant the injunction, but to shut it down.
What Is the 'High Degree of Probability' Standard and Why Does It Matter Here?
In the high-stakes arena of cross-border construction disputes, the arbitral seat is the jurisdictional anchor that dictates which court possesses supervisory authority over the proceedings. When that seat is ambiguously drafted, parties frequently race to their preferred forums, triggering parallel litigation and urgent applications for anti-suit injunctions. In Ledger v Leeor [2022] DIFC ARB 016, the claimant sought an interim anti-suit injunction to restrain the respondent from advancing proceedings in the onshore Dubai Courts. To succeed, Ledger was required to satisfy a stringent threshold: demonstrating a "high degree of probability" that the Dubai International Financial Centre (DIFC) was the agreed seat of arbitration. Justice Michael Black KC’s rigorous application of this standard serves as a critical jurisdictional filter, designed explicitly to prevent forum shopping and maintain comity between the parallel judicial systems operating within the Emirate of Dubai.
The factual matrix of the dispute perfectly illustrates the drafting pitfalls that necessitate such a high evidentiary bar. In September 2015, Ledger and Leeor executed a contract whereby Ledger agreed to pay AED 348,000,000 for the execution, completion, and defect remediation of a major residential tower project comprising 123 buildings. The dispute resolution mechanism contained within the Particular Conditions of Contract was fractured. Clause 67.3 mandated that disputes be finally settled under the rules of the DIFC-LCIA. However, Clause 67.5 explicitly stated that the governing law of the procedure would be the law of the United Arab Emirates and Dubai, and crucially, that the place of arbitration shall be Dubai.
When relations broke down, Leeor bypassed arbitration entirely and initiated proceedings in the Dubai Court of First Instance, Case Number 255 of 2022. Ledger responded by filing a jurisdictional challenge onshore and simultaneously rushing to the DIFC Courts for an ex parte injunction to halt the onshore litigation. Ledger’s core argument rested on the premise that the selection of DIFC-LCIA rules implicitly designated the DIFC as the default seat, thereby granting the DIFC Courts supervisory jurisdiction under Article 15 of the DIFC Arbitration Law.
Justice Black KC immediately identified the central jurisdictional hurdle. Before the Court could even entertain the traditional American Cyanamid factors for interim relief—such as the adequacy of damages or the balance of convenience—it had to establish its own authority to intervene. The standard for such intervention is deliberately onerous.
The question for me therefore is whether I am satisfied that there is a high degree of probability that there is a binding Arbitration Agreement with DIFC as its seat or if the seat is not DIFC whether this is one of those exceptional cases where the Court will nevertheless grant an anti-suit injunction.

The insistence on a "high degree of probability" is not merely a procedural quirk; it is a substantive doctrine rooted in the constitutional architecture of Dubai’s judicial system. The DIFC Courts and the onshore Dubai Courts operate as parallel, independent systems within the same Emirate. If the DIFC Courts were to grant anti-suit injunctions based on a mere "good arguable case" that the DIFC was the arbitral seat, they would risk routinely encroaching upon the jurisdiction of the onshore courts. Such overreach would inevitably trigger conflicts before the Joint Judicial Committee (JJC), the tribunal tasked with resolving jurisdictional clashes between the two courts. By demanding a high degree of probability, the DIFC Courts effectively filter out speculative applications and ensure that their coercive powers are deployed only when their supervisory mandate is undeniable.
This approach contrasts sharply with the Court's posture when the seat is unequivocally established. As seen in cases like ARB-032-2025: ARB 032/2025 Oswin v (1) Otila (2) Ondray, when an arbitration agreement explicitly names the DIFC as the seat, the Court will aggressively defend its jurisdiction and readily issue injunctions to restrain parallel proceedings brought in breach of the agreement. In Ledger, however, the contractual reference to "Dubai" as the place of arbitration introduced fatal ambiguity. While Ledger argued that the DIFC-LCIA rules pulled the seat into the DIFC, onshore courts have historically interpreted "Dubai" to mean non-DIFC Dubai, applying Federal Law No. 6 of 2018 on Arbitration.
Faced with this ambiguity, Justice Black KC refused to presume jurisdiction. The burden of proof rests heavily on the applicant seeking the injunction. Ledger failed to discharge this burden because the conflicting clauses in the construction contract made it impossible to conclude, to a high degree of probability, that the parties intended the DIFC to be the juridical seat. Without that certainty, the DIFC Court lacks the foundational authority to act as the supervisory court.
Ledger attempted to circumvent this strict requirement by arguing that, even if the seat were non-DIFC Dubai, the DIFC Courts still possessed the residual jurisdiction to grant an anti-suit injunction. To support this, Ledger relied on previous jurisprudence regarding the Court's broader injunctive powers.
Ledger refers to Brookfield at para 38
“I do not therefore accept that, even if the seat of the arbitration is non-DIFC Dubai, the Court has no jurisdiction to grant an anti-suit injunction but it would be an unusual and exceptional case where the Court did so, particularly bearing in mind the appropriate respect that the courts of the two different systems in the Emirate of Dubai must have for each other.
While Justice Black KC acknowledged this theoretical possibility, he strictly contained it. The power to enjoin proceedings in a sister court when the DIFC is not the seat is reserved for truly exceptional circumstances. The mere existence of a parallel proceeding in the Dubai Court of First Instance does not constitute an exceptional circumstance; rather, it is the predictable consequence of a poorly drafted arbitration clause. To intervene under such ordinary conditions would violate the principle of mutual respect that governs the relationship between the DIFC and onshore courts.
The analytical rigor applied by Justice Black KC underscores a vital lesson for commercial practitioners: the DIFC Courts will not act as a cure-all for defective drafting. If parties wish to benefit from the DIFC Courts' robust supervisory jurisdiction and their willingness to issue anti-suit injunctions, they must explicitly designate the DIFC as the seat in their contracts. Relying on institutional rules to imply the seat is a high-risk strategy that rarely survives judicial scrutiny when challenged.
Ultimately, the failure to establish the seat with the requisite certainty doomed Ledger's application before the merits of the injunction could even be fully weighed. Justice Black KC’s conclusion was absolute, cementing the high degree of probability standard as an insurmountable barrier for ambiguous claims.
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.

This ruling reinforces the DIFC Courts' sophisticated approach to their own jurisdiction. By refusing to lower the evidentiary bar, the Court prevents opportunistic litigants from weaponising ex parte applications to disrupt onshore proceedings. The high degree of probability standard ensures that the DIFC Courts remain a supportive forum for arbitration without overstepping their constitutional boundaries, thereby preserving the delicate jurisdictional equilibrium within the Emirate of Dubai. Practitioners must recognise that absent a clear, unequivocal designation of the DIFC as the arbitral seat, the doors to the Court's injunctive relief remain firmly closed.
How Did Justice Black Reach the Decision to Refuse the Injunction?
Justice Michael Black’s refusal to grant the requested relief was not born of a lack of statutory authority, but rather a deliberate exercise of judicial restraint rooted in the principles of comity. The analytical framework deployed by the Court required navigating a fundamental tension in modern cross-border arbitration: the duty of a supervisory court to hold parties to their arbitration agreements versus the imperative to respect the jurisdictional competence of parallel sovereign courts. To resolve this, Justice Black constructed a rigid threshold, demanding that an applicant seeking to halt onshore proceedings must prove the offshore seat with near certainty.
The Court first established its baseline jurisdictional competence. Ledger’s application hinged on the premise that the Dubai International Financial Centre (DIFC) Courts possessed the statutory machinery to intervene in the dispute. Justice Black readily affirmed this foundational point, confirming that the DIFC Court is fully equipped to issue an interim anti-suit injunction when the circumstances demand it.
I accept Ledger’s submission that this Court has the power to grant interim anti suit injunctions under Articles 10 and 32 of the DIFC Court Law 10 of 2004 in particular in aid of arbitration as contemplated by Article 15 of the DIFC Arbitration Law 1 of 2008.
This acknowledgment aligns with the broader trajectory of DIFC jurisprudence, which has historically positioned the offshore court as a robust protector of arbitral integrity. Much like the expansive supportive jurisdiction recognized in ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC [2013] DIFC ARB 003 and later refined in ARB-005-2025: ARB 005/2025 Nashrah v (1) Najem (2) Nex, the statutory power under Articles 10 and 32 of the DIFC Court Law is unquestioned. However, possessing the power to enjoin a party is entirely distinct from the jurisprudential wisdom of exercising it, particularly when the target of the injunction is actively litigating in a sister court within the same Emirate.
The central vulnerability in Ledger’s application was the ambiguity of the arbitration agreement itself. The underlying commercial relationship involved a massive construction project, with the financial stakes clearly defined by the parties' initial agreement.
In or around September 2015, the parties entered into an agreement wherein the Claimant agreed to pay the Defendant AED 348,000,000 for the Defendant to execute and complete the Project and the remedying of defects.
Despite the AED 348,000,000 valuation, the dispute resolution clause was poorly drafted, designating "Dubai" as the place of arbitration while simultaneously invoking the rules of the DIFC-LCIA. This created a classic jurisdictional fracture. Ledger attempted to bypass this ambiguity by arguing that the mere invocation of the DIFC-LCIA rules pulled the default seat into the offshore jurisdiction.
Ledger submits that the default seat of the arbitration agreement is the DIFC, as per the analysis above, and accordingly the DIFC Courts has jurisdiction to grant the interim injunction.
Justice Black rejected this automatic conflation of institutional rules with the legal seat. To grant an anti-suit injunction, the Court requires far more than a plausible argument or a default presumption; it requires an evidentiary standard that leaves little room for doubt. The Court articulated this standard explicitly, demanding a high degree of probability that the DIFC was the agreed seat.
The question for me therefore is whether I am satisfied that there is a high degree of probability that there is a binding Arbitration Agreement with DIFC as its seat or if the seat is not DIFC whether this is one of those exceptional cases where the Court will nevertheless grant an anti-suit injunction.
Because the contractual language pointed simultaneously to onshore Dubai and the offshore DIFC-LCIA, Ledger could not satisfy this rigorous evidentiary burden. The ambiguity was fatal to the primary ground for the injunction.
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.
Having determined that the seat was not definitively the DIFC, Justice Black was forced to confront the secondary question: could the DIFC Court issue an anti-suit injunction if the seat was, in fact, onshore Dubai? Ledger proposed a pragmatic, albeit aggressive, procedural maneuver. They asked the DIFC Court to act as a temporary shield, freezing the onshore litigation while the onshore court evaluated its own jurisdiction.
Ledger submits that the most appropriate way forward is for the DIFC Courts, being the supervisory court under the Arbitration Agreement, to intervene and issue an interim anti-suit injunction until the determination of the Defendant's Part 12 jurisdictional challenge and make any further order at that time if appropriate to do so.
This proposition struck at the very heart of judicial comity. Ledger was essentially asking the DIFC Court to preempt the Dubai Court of First Instance, Case Number 255 of 2022, dictating the pace and viability of proceedings before a coordinate sovereign tribunal. Justice Black’s reasoning here is the doctrinal core of the judgment. He relied heavily on the precedent set in Brookfield, emphasizing that while the DIFC Court might theoretically possess the jurisdiction to enjoin a party in a non-DIFC seated arbitration, exercising that jurisdiction requires extreme caution.
Ledger refers to Brookfield at para 38
“I do not therefore accept that, even if the seat of the arbitration is non-DIFC Dubai, the Court has no jurisdiction to grant an anti-suit injunction but it would be an unusual and exceptional case where the Court did so, particularly bearing in mind the appropriate respect that the courts of the two different systems in the Emirate of Dubai must have for each other.
The phrase "appropriate respect" is the operational mechanism of comity in the Emirate's dual-court system. The DIFC Court will not act as an appellate or supervisory body over the onshore Dubai Courts. If the parties have agreed to an onshore seat, the onshore courts are the exclusive masters of their own procedural domain. Justice Black made this boundary absolute.
It is clear to me that, if non-DIFC Dubai is the seat of the arbitration, this Court would not interfere with an order made by that court because of the existence of an arbitration agreement.
The only remaining avenue for Ledger was to prove that their situation fell into the narrow category of exceptional cases where the DIFC Court would intervene despite a non-DIFC seat. However, parallel litigation over a construction contract, even one valued at hundreds of millions of dirhams, is the standard fare of commercial disputes, not an exceptional anomaly. The mere inconvenience of litigating jurisdiction in the Dubai Courts does not trigger the DIFC Court’s extraordinary equitable powers.
Furthermore, Justice Black’s analysis did not stop at the jurisdictional and comity hurdles. He also subjected the application to the traditional, rigorous tests for interim injunctive relief, specifically focusing on the adequacy of damages and the balance of convenience. Even if a court has jurisdiction and comity is not offended, an injunction remains an equitable remedy of last resort.
If damages would be an adequate remedy and the defendant would be in a financial position to pay them, no interim injunction should normally be granted; and
ii. the court must consider whether, if the defendant were to succeed at trial, he would be adequately compensated by the plaintiff's undertaking in damages for the loss caused by being prevented from carrying out the work between the time of the application for the interim injunction and the trial.
The Court must weigh the financial realities of both parties. If Ledger could be made whole through a subsequent award of damages for breach of the arbitration agreement, the draconian step of halting parallel litigation is unwarranted. Conversely, the Court must consider the harm inflicted on Leeor if they are wrongfully enjoined from pursuing their claims onshore.
If he would be adequately compensated, then an interim injunction should be granted.
c) if there is doubt as to the adequacy of damages to the claimant or the defendant, the court must consider the 'balance of convenience'.
By systematically dismantling Ledger’s application—first on the ambiguity of the seat, second on the principles of comity, and finally on the traditional metrics of equitable relief—Justice Black reinforced a critical boundary. The DIFC Courts will vigorously defend arbitrations seated within their jurisdiction, but they will not allow their injunctive powers to be weaponized to cure defective drafting or to undermine the authority of the onshore Dubai Courts. The threshold for interference remains exceptionally high, demanding clear contractual intent and an undeniable threat to the arbitral process that cannot be remedied by damages alone.
How Does the DIFC Approach Compare to English High Court Practice?
The English High Court has long grappled with the delicate mechanics of the anti-suit injunction. While the English Commercial Court recognises the injunction as a vital tool to enforce the negative obligations embedded within an arbitration agreement, it deploys the remedy with acute sensitivity to international comity. An anti-suit injunction, though technically directed in personam against a litigating party, inevitably interferes with the process of the competing forum. Consequently, English jurisprudence demands a "high degree of probability" that an arbitration agreement exists and that the English court is the agreed supervisory seat before it will restrain foreign proceedings. Justice Michael Black’s reasoning in Ledger v Leeor [2022] DIFC ARB 016 confirms that the Dubai International Financial Centre (DIFC) Courts have fully internalised this English doctrine of restraint, applying it rigorously to the complex jurisdictional architecture of the Emirate of Dubai.
The factual matrix of the dispute provided a classic testing ground for these principles. Ledger, the developer of a massive project comprising 123 residential building units, sought to halt Leeor, a construction contractor, from pursuing litigation in the onshore Dubai Courts over a AED 348,000,000 final account and defect dispute. Ledger relied heavily on Clause 67.3: Arbitration, which mandated DIFC-LCIA rules, but the contract simultaneously designated the place of arbitration simply as "Dubai" and the governing law as the law of the UAE and Dubai.
Faced with this ambiguity, Leeor bypassed arbitration entirely and initiated proceedings onshore in Case Number 255 of 2022 before the Dubai Court of First Instance. Ledger’s subsequent ex parte application to the DIFC Court for an interim anti-suit injunction forced Justice Black to articulate exactly how aggressively the DIFC Court would police its own potential jurisdiction.
The baseline approach of the DIFC Court mirrors the English Angelic Grace doctrine: where the seat is undisputed, the supervisory court will act decisively to hold parties to their bargain. Justice Black affirmed this starting point without hesitation:
I accept that where there is no issue that that the parties are bound to an arbitration agreement and that DIFC is the seat of the arbitration, the Court would readily grant an injunction restraining the continuation proceedings brought in breach of the Arbitration Agreement.
However, the English High Court practice dictates that this readiness evaporates the moment the seat becomes ambiguous. If a claimant cannot establish to a high degree of probability that the forum court is the designated seat, the justification for interfering with a competing court collapses. Justice Black adopted this exact threshold, refusing to grant equitable relief on a mere arguable case regarding the seat. Because the contract's reference to "Dubai" failed to clearly distinguish between the DIFC and onshore Dubai, the jurisdictional foundation for the injunction was fatally compromised:
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.
This strict adherence to the probability threshold prevents the DIFC Court from becoming a tactical weapon for parties seeking to derail onshore litigation. Ledger attempted to circumvent this high bar by arguing that the DIFC Court possessed a broader, residual power to grant interim relief in support of arbitration under Articles 10 and 32 of the DIFC Court Law, regardless of the ultimate determination of the seat.
While Justice Black acknowledged the theoretical existence of this power, he severely restricted its practical application, invoking principles of comity that are deeply familiar to English commercial practitioners. In English law, granting an anti-suit injunction against proceedings in a foreign court where England is not the seat is an exceptional measure, typically reserved for cases where the foreign proceedings are demonstrably vexatious or oppressive. Justice Black applied a parallel logic to the relationship between the DIFC Courts and the onshore Dubai Courts. Quoting previous DIFC authority, he outlined the doctrine of exceptionality:
Ledger refers to Brookfield at para 38
“I do not therefore accept that, even if the seat of the arbitration is non-DIFC Dubai, the Court has no jurisdiction to grant an anti-suit injunction but it would be an unusual and exceptional case where the Court did so, particularly bearing in mind the appropriate respect that the courts of the two different systems in the Emirate of Dubai must have for each other.
This concept of "appropriate respect" is the DIFC equivalent of international comity. The DIFC Court maintains a respectful distance from the Dubai Courts, refusing to act as an appellate or supervisory body over onshore judges who are equally capable of determining their own jurisdiction and staying proceedings under the UAE Federal Arbitration Law.
Ledger’s secondary strategy relied on general equitable principles, specifically the 'balance of convenience' test derived from the English American Cyanamid framework. Ledger argued that the DIFC Court should freeze the onshore proceedings temporarily, simply to preserve the status quo until the jurisdictional challenge could be fully ventilated. This argument fundamentally misunderstands the hierarchy of tests in anti-suit injunction applications.
In both English and DIFC practice, the balance of convenience is a secondary consideration. It only triggers if the primary jurisdictional threshold—the high degree of probability of a local seat—is met. A claimant cannot use the lower standard of the balance of convenience to bypass a fundamental lack of jurisdictional certainty. Furthermore, even within the realm of general equitable relief, the court must first assess whether damages would be an adequate remedy. Justice Black explicitly incorporated this traditional equitable hurdle into his analysis of the arbitration dispute:
If damages would be an adequate remedy and the defendant would be in a financial position to pay them, no interim injunction should normally be granted; and
ii. the court must consider whether, if the defendant were to succeed at trial, he would be adequately compensated by the plaintiff's undertaking in damages for the loss caused by being prevented from carrying out the work between the time of the application for the interim injunction and the trial.
By enforcing the adequacy of damages test, the DIFC Court aligns itself with the orthodox English view that equitable remedies are discretionary and exceptional. If Leeor's pursuit of onshore litigation constituted a breach of the arbitration agreement, Ledger could theoretically claim damages for breach of contract—specifically, the wasted costs of defending the onshore proceedings. Unless Ledger could prove that such damages would be inadequate or impossible to recover, the drastic remedy of an anti-suit injunction remained unjustified.
This restrained approach marks a critical maturation in the DIFC's arbitral jurisprudence. In earlier eras, decisions like ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC established the DIFC Courts' willingness to act as a robust conduit jurisdiction, aggressively supporting arbitration and enforcing awards even with minimal territorial connection. However, Ledger v Leeor demonstrates that this supportive stance has strict doctrinal limits. The DIFC Court will not allow its pro-arbitration mandate to mutate into a mechanism for inter-court conflict.
Similarly, the boundaries of supportive jurisdiction explored in ARB 005/2025: ARB 005/2025 Nashrah v (1) Najem (2) Nex reflect this ongoing calibration. The DIFC Court is acutely aware of its position within the broader UAE legal ecosystem. By adopting the English High Court's stringent requirements for anti-suit injunctions—demanding a high probability of a local seat, requiring exceptional circumstances for non-seat intervention, and strictly applying the adequacy of damages test—Justice Black ensured that the DIFC Court remains a predictable, restrained, and respectful supervisory forum. The ruling sends a clear message to commercial litigators: the DIFC Court is not a rubber stamp for ex parte injunctions, and ambiguous drafting regarding the seat of arbitration will strip a claimant of the powerful equitable remedies that a clearly defined DIFC seat would otherwise guarantee.
Which Earlier DIFC Cases Frame This Decision?
The application brought by Ledger before the Dubai International Financial Centre (DIFC) Court of First Instance presented a familiar pathology in regional construction disputes: a poorly drafted arbitration clause that fractured the dispute resolution process across parallel forums. Ledger sought an interim anti-suit injunction to restrain Leeor from advancing proceedings in the onshore Dubai Court of First Instance. The core of Ledger’s argument rested on the premise that the DIFC Court possessed the requisite jurisdiction to halt the onshore litigation because the arbitration agreement, by referencing the DIFC-LCIA rules, implicitly designated the DIFC as the arbitral seat.
Ledger’s strategic posture relied heavily on positioning the DIFC Court as the primary guardian of the arbitral process. The claimant argued that the offshore court was obligated to step in and preserve the integrity of the arbitration agreement while jurisdictional challenges were resolved elsewhere. As captured in the judgment, the claimant’s position was unequivocal:
Justice Michael Black did not dispute the theoretical foundation of the DIFC Court’s authority. The statutory framework clearly empowers the offshore court to issue interim measures in support of arbitration. Acknowledging this baseline, Justice Black confirmed the power to grant interim anti suit injunctions under Articles 10 and 32 of the DIFC Court Law 10 of 2004, read in conjunction with Article 15 of the DIFC Arbitration Law 1 of 2008.
However, possessing a statutory power and exercising it to enjoin a sister court within the same Emirate are vastly different propositions. The jurisprudence of the DIFC Courts has consistently maintained a strict boundary regarding its supervisory role, particularly when the seat of arbitration is contested or explicitly located onshore. Justice Black articulated the general rule governing clear-cut cases where the seat is undisputed:
The fatal flaw in Ledger’s application was the ambiguity of the seat. The underlying contract stipulated that the "place of arbitration shall be Dubai," while simultaneously invoking the DIFC-LCIA rules. Ledger attempted to leverage this ambiguity, arguing that the reference to the institutional rules effectively pulled the default seat into the offshore jurisdiction.
To resolve this tension, Justice Black anchored his analysis in the precedent established by the Brookfield litigation. The Brookfield doctrine serves as the definitive framework for managing the delicate judicial comity between the DIFC Courts and the onshore Dubai Courts. When an applicant asks the DIFC Court to issue an anti-suit injunction against proceedings already underway in the onshore courts, they are asking for an extraordinary intervention that risks creating a direct conflict between the two judicial systems. Relying on this established boundary, Justice Black cited the critical threshold from Brookfield:
This reliance on Brookfield cements a crucial doctrinal point: the DIFC Court will not act as a default supervisory body for non-DIFC seated arbitrations. The requirement for an unusual and exceptional case acts as a severe filter, preventing parties from using the offshore court as a tactical weapon to derail onshore litigation when the arbitration agreement fails to clearly designate the DIFC as the seat. The mutual respect between the parallel systems demands that the DIFC Court exercise extreme restraint unless the jurisdictional hook is undeniable.
Faced with the Brookfield standard, Justice Black formulated the precise legal test that Ledger had to satisfy to secure the injunction. The burden was entirely on the claimant to elevate the ambiguous contractual language into a near-certainty regarding the seat, or alternatively, to prove that the circumstances were so extraordinary that intervention was justified regardless of the seat.
Ledger failed to meet this rigorous standard. The mere reference to the DIFC-LCIA rules, juxtaposed against the explicit designation of "Dubai" as the place of arbitration, could not generate the high degree of probability required to trigger the DIFC Court's primary supervisory jurisdiction. Without that high probability, the foundation for the anti-suit injunction collapsed. Justice Black’s conclusion on this point was definitive:
This restrictive approach to supervisory jurisdiction stands in sharp contrast to the DIFC Court’s historically expansive approach to enforcement jurisdiction, most notably articulated in ARB-003-2013: Banyan Tree Corporate PTE Ltd v Meydan Group LLC [2013] DIFC ARB 003. In Banyan Tree, the DIFC Court confirmed its willingness to act as a conduit jurisdiction for the recognition and enforcement of arbitral awards, even when the underlying dispute and the parties had no direct connection to the DIFC, provided the statutory criteria for enforcement were met.
However, Ledger v Leeor clarifies the absolute limits of the Banyan Tree philosophy. While the DIFC Court may open its doors wide for the enforcement of finalized awards, it firmly shuts them when asked to interfere with the ongoing processes of the onshore courts in disputes where the seat is not clearly offshore. The distinction between enforcement and supervision is paramount. The court will not allow its robust pro-arbitration stance to override the appropriate respect that the courts of the two different systems must maintain. Justice Black reinforced this boundary explicitly:
It is clear to me that, if non-DIFC Dubai is the seat of the arbitration, this Court would not interfere with an order made by that court because of the existence of an arbitration agreement.
Beyond the jurisdictional hurdles, the decision also reiterates the strict financial mechanics governing the issuance of interim injunctions. Even if Ledger had managed to establish a high probability that the DIFC was the seat, the application would still have to survive the traditional test for interim relief, which heavily scrutinizes the adequacy of damages. The DIFC Court does not grant injunctions simply because an arbitration agreement has been breached; the applicant must prove that financial compensation would be an insufficient remedy for the harm caused by the parallel litigation.
The ruling in Ledger v Leeor serves as a definitive restatement of the DIFC Court’s jurisdictional boundaries regarding anti-suit injunctions. By strictly applying the Brookfield doctrine and demanding a high degree of probability regarding the arbitral seat, Justice Black ensured that the offshore court remains a supportive, rather than disruptive, force within the broader Dubai legal ecosystem. Practitioners drafting arbitration clauses must recognize that ambiguity regarding the seat will not be resolved in favor of DIFC supervision by default. When the contractual language wavers between onshore and offshore jurisdictions, the DIFC Court will prioritize judicial comity and refuse to wield its injunctive powers to rescue parties from the consequences of their own imprecise drafting.
What Does This Mean for Practitioners and Future Claimants?
Drafting precision remains the only reliable defense against the jurisdictional uncertainty that routinely plagues arbitration agreements in the United Arab Emirates. For commercial litigators and transactional counsel structuring high-value deals, the refusal of interim relief in Ledger v Leeor serves as a severe warning regarding the limits of the Dubai International Financial Centre (DIFC) Courts' supervisory jurisdiction. When parties fail to explicitly designate the DIFC as the seat of arbitration, they forfeit the predictable, arbitration-friendly intervention that the offshore jurisdiction is known for, leaving themselves vulnerable to protracted parallel proceedings in the onshore courts.
The commercial stakes in such jurisdictional battles are rarely trivial. In this instance, the underlying conflict involved a AED 348,000,000 construction contract for a major residential development. Despite the massive financial exposure, the dispute resolution mechanism contained in Clause 67.5 of the Particular Conditions of Contract merely stated that the "place of arbitration shall be Dubai." That single omission—the failure to append the four letters "DIFC" to the word "Dubai"—proved fatal to Ledger’s strategy for halting the onshore litigation. The claimant’s assumption that the DIFC Courts would automatically step in to protect the arbitration agreement fundamentally misjudged the high evidentiary threshold required for an anti-suit injunction when the seat is contested.
To secure an interim anti-suit injunction from the DIFC Courts, an applicant must satisfy a stringent legal test. It is not enough to show that an arbitration agreement exists or that the respondent is arguably in breach of it by litigating elsewhere. The applicant must establish the court's jurisdiction to intervene, which hinges entirely on the seat. Justice Michael Black articulated the governing standard with absolute clarity:
The question for me therefore is whether I am satisfied that there is a high degree of probability that there is a binding Arbitration Agreement with DIFC as its seat or if the seat is not DIFC whether this is one of those exceptional cases where the Court will nevertheless grant an anti-suit injunction.
The requirement for a high degree of probability regarding the seat places a heavy burden on the claimant at the ex parte stage. Ledger attempted to argue that because the arbitration was to be administered under the rules of the DIFC-LCIA, the default seat should be construed as the DIFC. While institutional rules can sometimes provide interpretive guidance, they cannot override the express, albeit ambiguous, geographical designation of "Dubai" combined with a governing law clause pointing to the "law of United Arab Emirates and of Dubai." The court found that this linguistic formulation pointed just as strongly, if not more so, to onshore Dubai as the intended seat.
Because the contractual language was equivocal, Ledger could not meet the required standard of proof. Justice Black’s reasoning leaves no room for doubt regarding the consequences of such ambiguity:
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.
This strict approach to the "high degree of probability" test underscores a broader judicial philosophy within the DIFC. The court is acutely aware of its position within the dual-system architecture of the Emirate of Dubai. While the DIFC Court possesses the statutory authority to grant injunctions under Articles 10 and 32 of the DIFC Court Law 10 of 2004, it exercises that power with extreme caution when the target of the injunction is a proceeding in the onshore Dubai Courts. Judicial comity demands that the offshore court refrain from usurping the jurisdiction of its onshore counterpart unless its own supervisory mandate is undeniable.
Practitioners must recognize that the DIFC Court will not act as a universal guarantor of arbitration agreements across the UAE. If the seat is arguably onshore, the DIFC Court will defer to the onshore judiciary to determine the validity and scope of the arbitration clause. As Justice Black noted, relying on precedent from Brookfield, it would be an "unusual and exceptional case" for the DIFC Court to issue an anti-suit injunction if the seat were non-DIFC Dubai. In standard commercial and construction disputes, establishing such "exceptional circumstances" is virtually impossible. The mere fact that a party is breaching an arbitration agreement by suing in the Dubai Court of First Instance does not, in itself, constitute an exceptional circumstance warranting cross-system interference.
It is clear to me that, if non-DIFC Dubai is the seat of the arbitration, this Court would not interfere with an order made by that court because of the existence of an arbitration agreement.
The strategic fallout for Ledger is severe and instructive. By failing to secure the interim injunction, Ledger is now forced to fight a multi-front war. It must continue to litigate its jurisdictional challenge within the Dubai Court of First Instance—a process that can be time-consuming and procedurally complex—while simultaneously attempting to initiate or preserve its rights in arbitration. This is the exact scenario that an arbitration agreement is designed to prevent. The costs, delays, and tactical disadvantages of parallel proceedings are immense, particularly in a dispute valued at hundreds of millions of dirhams.
Ledger’s predicament is not unique, but rather a recurring theme in UAE jurisprudence, as explored extensively in ARB-006-2024: ARB 006/2024 Neville v Nigel. The "Dubai Arbitration Trap"—where parties specify "Dubai" as the venue or place without explicitly designating the DIFC—continues to ensnare sophisticated commercial actors. The assumption that offshore institutional rules (like those of the now-abolished DIFC-LCIA) will automatically pull the seat into the DIFC is a dangerous fallacy. The courts will look first and foremost at the express words used by the parties. If those words are "Dubai," the presumption leans heavily toward the onshore jurisdiction, bringing with it the application of the UAE Federal Arbitration Law rather than the DIFC Arbitration Law.
For transactional counsel, the mandate is absolute: the arbitration clause must state, verbatim, that "the seat of the arbitration shall be the Dubai International Financial Centre (DIFC)." Any deviation from this precise formulation invites jurisdictional challenges and strips the client of the ability to obtain swift, ex parte relief from the DIFC Courts.
For litigators inheriting ambiguous clauses, the Ledger v Leeor order dictates a recalibration of strategy. If the seat is not explicitly the DIFC, an application for an anti-suit injunction in the offshore courts is highly likely to fail, resulting in wasted costs and a loss of tactical momentum. Counsel must be prepared for the DIFC Court to decline jurisdiction entirely if the seat is even arguably outside its territory. Instead of relying on the DIFC Courts to rescue a poorly drafted clause, litigators must focus their efforts on raising the arbitration defense directly within the onshore proceedings, adhering strictly to the procedural requirements of the UAE Civil Procedure Code to avoid inadvertently submitting to the onshore court's jurisdiction.
Ultimately, the refusal of the injunction at 3pm on October 7, 2022, was not a failure of the DIFC Courts to support arbitration, but a strict adherence to the boundaries of its own jurisdiction. The court cannot rewrite contracts to save parties from their own drafting ambiguities. In the high-stakes arena of UAE construction and commercial litigation, precision is not merely a stylistic preference; it is the jurisdictional key that unlocks the supervisory powers of the court. Without it, claimants are left to navigate the very procedural quagmires they sought to avoid.
What Issues Remain Unresolved in the Wake of Ledger v Leeor?
The refusal of the interim anti-suit injunction in Ledger v Leeor [2022] DIFC ARB 016 exposes a persistent fault line in Dubai’s bifurcated legal system. While Justice Michael Black’s 7 October 2022 order decisively halted Ledger’s ex parte application, the underlying tension between the DIFC Courts and the onshore Dubai Courts remains a highly dynamic area of law. The dispute, stemming from a AED 348,000,000 construction agreement, forces practitioners to confront the limits of the DIFC Courts' supervisory jurisdiction when the arbitral seat is ambiguously drafted. The ruling leaves several critical questions unanswered, particularly regarding the threshold for judicial intervention and the procedural sequencing of jurisdictional challenges.
The most glaring unresolved issue is the exact circumstances that would constitute an 'exceptional case' for an anti-suit injunction remain largely undefined. Justice Black acknowledged the theoretical power to intervene but set an extraordinarily high bar for its exercise. The jurisprudence relies heavily on the concept of inter-court comity, yet provides little concrete guidance on what factual matrix would override that comity.
Ledger refers to Brookfield at para 38
“I do not therefore accept that, even if the seat of the arbitration is non-DIFC Dubai, the Court has no jurisdiction to grant an anti-suit injunction but it would be an unusual and exceptional case where the Court did so, particularly bearing in mind the appropriate respect that the courts of the two different systems in the Emirate of Dubai must have for each other.
By invoking the Brookfield standard, the Court confirms that the door to non-seat intervention is not entirely closed, but it remains firmly bolted in all but the most extreme scenarios. The analytical framework requires the applicant to clear a dual hurdle, forcing the Court to evaluate both the probability of the seat and the nature of the circumstances.
The question for me therefore is whether I am satisfied that there is a high degree of probability that there is a binding Arbitration Agreement with DIFC as its seat or if the seat is not DIFC whether this is one of those exceptional cases where the Court will nevertheless grant an anti-suit injunction.
42.
Because Ledger failed to establish a high degree of probability that the DIFC was the seat, the analysis shifted to the "exceptional case" limb. However, the judgment stops short of enumerating the factors that might constitute such an exception. Would evidence of bad faith litigation tactics in the onshore courts suffice? Would a parallel proceeding that threatens to entirely dissipate the disputed assets trigger intervention? The lack of a defined taxonomy for "exceptional cases" leaves commercial parties guessing, forcing them to litigate the boundaries of comity on a case-by-case basis. The ambiguity in Clause 67.5, which designated the rules of the DIFC-LCIA but stated the place of arbitration was "Dubai," created the very jurisdictional vacuum that Leeor exploited by filing in the onshore courts.
If that is so, then it cannot be said that there is a high degree of probability that there is a binding arbitration agreement with DIFC as its seat, and I cannot therefore grant an anti-suit injunction on that basis even assuming I am satisfied that Leeor is in breach of the Arbitration Agreement.
47.
The historical context of the Joint Judicial Committee (JJC) looms large over these proceedings. The JJC was established precisely to resolve conflicts of jurisdiction between the onshore and offshore courts. By refusing to grant the injunction, Justice Black effectively avoids creating a direct conflict that would inevitably be referred to the JJC, thereby stalling the arbitration entirely. However, this judicial restraint comes at a cost. It leaves the applicant exposed to the very onshore proceedings they contracted to avoid. The jurisprudence requires a delicate balancing act: respecting the jurisdiction of the Dubai Courts while simultaneously upholding the sanctity of the arbitration agreement.
The procedural mechanics of seeking an anti-suit injunction alongside a pending jurisdictional challenge present another area requiring urgent clarification. Ledger’s strategy was explicitly designed to use the injunction as a temporary shield.
Ledger submits that the most appropriate way forward is for the DIFC Courts, being the supervisory court under the Arbitration Agreement, to intervene and issue an interim anti-suit injunction until the determination of the Defendant's Part 12 jurisdictional challenge and make any further order at that time if appropriate to do so.
18.
This approach attempts to bridge the gap between the immediate threat of onshore litigation and the slower machinery of a Part 12 jurisdictional determination. Yet, the Court's refusal to grant the interim relief suggests a reluctance to use anti-suit injunctions as mere holding patterns. The interaction between Part 12 challenges and the timing of anti-suit applications needs further procedural guidance. If an applicant cannot secure an interim injunction while the DIFC Court determines its own jurisdiction, the onshore proceedings may advance to a stage where the jurisdictional challenge becomes practically moot.
Furthermore, the Rules of the DIFC Courts (RDC) Part 12 provide a structured mechanism for disputing the Court's jurisdiction. When a defendant like Leeor files a Part 12 application, the Court is obligated to determine its own competence before proceeding to the merits. Ledger's attempt to bypass this sequential logic by seeking an urgent ex parte injunction highlights a critical vulnerability in the RDC framework. If the Court cannot issue protective measures while its jurisdiction is under review, the utility of the DIFC Courts as a supervisory jurisdiction is severely compromised in cases of seat ambiguity. This procedural friction undermines the efficacy of the DIFC Arbitration Law 1 of 2008 and leaves applicants vulnerable during the critical window between filing a Part 12 application and its resolution.
The statutory basis for the Court's power is not in dispute. Justice Black explicitly confirmed the jurisdictional anchor for such relief.
I accept Ledger’s submission that this Court has the power to grant interim anti suit injunctions under Articles 10 and 32 of the DIFC Court Law 10 of 2004 in particular in aid of arbitration as contemplated by Article 15 of the DIFC Arbitration Law 1 of 2008.
20.
The existence of the power under Articles 10 and 32 of the DIFC Court Law 10 of 2004 is clear, but the mechanics of its deployment remain opaque. When a party initiates proceedings in the Dubai Court of First Instance, as Leeor did on 14 June 2022, the race to secure supervisory jurisdiction begins. The DIFC Courts' hesitation to intervene without a definitively established seat creates a tactical advantage for the party that strikes first in the onshore courts, effectively shifting the burden of proof onto the party seeking to uphold the arbitration agreement.
The final, and perhaps most consequential, unresolved issue is the ultimate determination of the seat itself. Justice Black’s order was explicitly framed as an interim decision, and the granting of permission to appeal under Rule 44.6 of the Rules of the DIFC Courts signals that the appellate bench will need to grapple with these questions. The impact of the Court's permission to appeal suggests that the final word on seat determination in this dispute is yet to be written. The order noted that there is a compelling reason for the appeal to be heard, a phrase that often serves as a judicial bat-signal for issues of systemic importance requiring appellate clarification.
The broader context of arbitration appeals in the DIFC reveals a growing intolerance for tactical delays, but also a recognition that complex jurisdictional questions require rigorous appellate scrutiny. As seen in the recent analysis of ARB-027-2024: ARB 027/2024 Nalani v Netty, the DIFC Courts are increasingly focused on the price of procedural obstruction. In Ledger v Leeor, the appellate court's eventual ruling will likely dictate how future litigants draft their arbitration clauses and how aggressively they can pursue parallel onshore litigation. If the Court of Appeal upholds the strict interpretation of the "exceptional case" standard, parties with ambiguous arbitration clauses will find the DIFC Courts a much less hospitable forum for urgent injunctive relief.
Until the Court of Appeal provides definitive guidance, the tension between the DIFC and onshore Dubai Courts will continue to generate complex, multi-front litigation. Practitioners must navigate a landscape where the theoretical availability of an anti-suit injunction is heavily circumscribed by the practical realities of inter-court comity. The failure to secure an injunction in a dispute of this magnitude serves as a stark warning: ambiguity in drafting the arbitral seat cannot be easily cured by an ex parte application to the DIFC Courts. The jurisprudence demands a high degree of probability, and absent that, only the most extraordinary circumstances will prompt the DIFC Courts to cross the jurisdictional divide.
