You Lost a DIFC-Seated Arbitration: Can the Court Set Aside the Award?

Only on a short list of grounds, and only if you apply in time. Under Article 41 of the DIFC Arbitration Law, the DIFC Court can set aside an award made in a DIFC-seated arbitration if one of the grounds in Article 41(2) is proved or found, and the application must normally be made within three months of receiving the award. A set-aside claim is not an appeal. The Court will not decide whether the tribunal got the facts or the law right, and in Olan v Obelix it treated a complaint that the tribunal had relied on a forged document as disagreement with the tribunal's assessment of the evidence, whether it was put as unfair procedure or as public policy.

Challenges do succeed where the problem is fairness rather than the result. In April 2026 the Court of Appeal set aside the parts of an award in a Dubai International Arbitration Centre (DIAC) arbitration resting on a claim the losing bank never had a fair chance to answer, and in August 2026 the Court of First Instance set aside a whole award, and the recognition order the winner already held, because the majority had decided points neither side had argued, a decision the winner has since sought to appeal. The table sets each ground against what has to be shown and how it has fared.

Is a set-aside claim an appeal against the award?

No. Article 41(1) of the Arbitration Law, DIFC Law No. 1 of 2008 makes an application to set aside the only recourse to a court against an award made in the seat of the DIFC, and Article 41(2) allows it only on the grounds listed. The Court of Appeal in Lachesis v Lacrosse [2021] DIFC CA 005 read that with Article 10, which bars DIFC Court intervention except as the Law provides, as meaning that the Court has no power to set an award aside outside those grounds, and that it keeps a discretion even where one is made out. Errors of law and errors of fact are not grounds, merits arguments dressed up as unfairness are scrutinised, and a trivial technical breach without consequences will not necessarily do, because this is not a game of procedural snakes and ladders.

The forum is fixed. The application may only be made to the DIFC Court, and Article 14(A)(6) of Dubai Law No. 2 of 2025 gives the DIFC Courts exclusive jurisdiction over claims related to an arbitration seated in the DIFC. Lachesis, Muzama v Mihanti and Nazeer v Noah were decided before that Law replaced the earlier courts legislation, but the provisions they applied are unchanged. The claim is brought by arbitration claim form under Part 43 of the Rules of the DIFC Courts, and Rule 43.41 has it heard otherwise than in open court unless the Court orders otherwise.

How long do you have, and when does the three months start?

Three months from the date you received the award, not the date printed on it. Article 41(3) allows two changes. If a party asked the tribunal under Article 40 to correct or interpret the award or to make an additional award, the three months run from the date that request was disposed of, and the parties may agree a longer period in writing. Rule 43.54 restates all three. An Article 40 request has its own window of thirty days from receipt, unless the parties agreed another period.

Counting follows the Schedule to the Law. The period starts on the day after receipt, and if its last day is an official holiday or a non-business day where the award was received, it runs to the next business day.

Deadline warning. A DIFC Authority consultation draft of June 2026 would replace three months with 30 days in Article 41(3). The consultation paper says not to rely on the draft until it is formally enacted, and on 15 October 2026 the DIFC legal database showed no enactment notice for it. Check again before counting.

Three points frame every challenge.

The winner already holds a recognition order: what happens to it?

It can stand, be stayed, or fall with the award, and the set-aside claim usually decides which. A winner may apply without notice under Rule 43.62. Rule 43.70 then gives the losing party 14 days after service, or a period the Court sets for service outside Dubai, to apply to set the order aside, and the award must not be enforced until that period ends or a timely application is finally disposed of.

In Olan v Obelix, ARB 053/2025 and ARB 054/2025, the employer on a construction project issued its set-aside claim on 29 December 2025 and the contractor a recognition claim the next day. A recognition order made without notice on 16 January 2026, by a judge unaware of the set-aside claim, was stayed when the claims were consolidated on 31 March 2026, because there was no useful purpose in enforcing an award that might be set aside. The challenge to the recognition order rose or fell with the Article 41 claim, and when that failed in June 2026 the stay was discharged.

Princeton v Persephone, ARB 015/2026 and ARB 027/2026, shows the other outcome. The set-aside claim was dated 2 March 2026 and the winner obtained a recognition order without notice on 6 May 2026. After the losing party applied under Rule 43.70 and Article 44(2), the Court refused the winner's application for security and prohibited enforcement until the set-aside claim was decided, and on 14 August 2026 it set aside the award and the recognition order. A costs ruling of 21 September 2026 held that the winner had breached its duty of full and frank disclosure by not telling the Court of the pending set-aside claim when it applied without notice, and that the application would probably have been directed to be heard on notice.

Article 44(3) makes the seat challenge the route that matters, because it bars a party seeking recourse against a DIFC-seated award from relying on the grounds in Article 44(1)(a) to resist recognition if it has made, or could have made, an Article 41 application.

When does a complaint that you were not heard succeed?

When the award turns on a point you never had a fair chance to answer, and your answer could realistically have changed the result. In Oheo Bank v Parker [2025] DIFC CA 006, which it described as the first appellate consideration of the principles behind Articles 41(2)(a)(ii) and (iii), the Court of Appeal required real unfairness or real practical injustice, a failure to meet minimum standards of due process, judged on the facts. The ground protects a party from injustice, not from its own decisions, so the line falls between having no opportunity and not taking one that existed. The applicant need not show the result would have been different, only that what it would have argued was reasonably arguable and could reasonably, not fancifully, have made a difference.

A customer's claim against a bank had succeeded on a theory first raised in the customer's post-hearing brief. The bank's brief listed about twenty unpleaded allegations, including that one, declined to engage with them, and asked the tribunal to direct a supplemental brief if it wanted them addressed. The majority upheld the new claim without doing so. The Court of Appeal held that the majority, if impressed by the new claim, should have put it to the bank as the bank had asked, found the bank's answers of contributory negligence and voluntary assumption of risk reasonably arguable, and set aside the paragraphs of the award giving effect to the claim.

Princeton applied the same test to an arbitration decided on the documents, where the majority held that the parties had no agreed date for payment, a point neither side had pleaded or argued.

Did the award decide something that was never referred to the tribunal?

Rarely, because the Court reads the reference broadly. Article 41(2)(a)(iii) covers an award that deals with a dispute outside the terms of the submission to arbitration, or contains decisions on matters beyond its scope. In Muzama v Mihanti [2022] DIFC ARB 004 the Court held that the two limbs differ. The first concerns the dispute as a whole and can justify setting aside the entire award, while the second concerns particular decisions and allows only those, and anything inseparable from them, to be set aside. It also held that the submission is not confined to the Terms of Reference, so a point in play on the pleadings and submissions is within it.

Oheo set the approach. The Court looks in the round at the pleadings, lists of issues, opening statements, evidence and closing submissions to decide what was in play. Pleadings are the starting point but not necessarily the finishing point, and the Court declined to follow a stricter line of authority requiring an amendment before a new issue enters the reference. On that test the bank's scope challenge failed, although its fairness challenge succeeded. In Olan the Court held that changes in the value claimed for heads of a final account already referred did not create a new dispute, and, rejecting a complaint that an issue listed in the Terms of Reference went undecided, that those terms cannot force a party to pursue a claim it has chosen to withdraw.

The tribunal relied on a document you say was forged: is that a ground?

Not on its own, where the tribunal heard the allegation and decided it. In Olan the employer alleged that a variation document was forged, because it was dated more than a year after the person whose signature it bore had left the project. The tribunal refused to direct production of the original, refused to suspend the arbitration while a criminal complaint was pursued, admitted the document, and rejected the employer's evidence, which included a handwriting expert.

The Court rejected each way the complaint was put. The refusal to suspend was the tribunal's decision to make and not reviewable under Article 41. The procedural order deeming documents authentic unless disputed did not say how a dispute would be decided, so Article 26(2), giving the tribunal power to determine admissibility and weight, applied and the agreed procedure was not breached. The employer had presented its case, and there was no evidence its expert would have said anything different with the original. Put as public policy, on the footing that the award risked being tainted by fraud and would undermine a police investigation, the argument was the same disagreement with the tribunal's evidential assessment, and the police would pursue their enquiries independently of the award.

Key takeaway. Olan decides that disagreeing with how a tribunal weighed contested evidence of authenticity is not a ground, whether the complaint is put as procedure or as public policy.

Can the public policy of the UAE carry the challenge?

Only in exceptional cases, and usually with evidence. Article 41(2)(b)(iii) allows an award to be set aside if the Court finds it in conflict with the public policy of the UAE. The Court of Appeal in Lachesis said that particular caution is needed before the DIFC Court pronounces on UAE public policy, that it will rarely be able to without expert evidence, and that the exception is reserved for exceptional circumstances with a very high standard of proof. Olan explained that this is not a different standard of proof but a demand for very strong evidence, and that a challenge brought without evidence must show that the award fundamentally offends the most basic and explicit principles of justice and fairness, or intolerable ignorance or corruption on the part of the tribunal.

Muzama shows how narrow the focus is. The losing employer relied on a separate award finding that the contractor had made an arrangement with a politician in an attempt to influence the employer, conduct that tribunal called unethical and illicit. The Court assumed, without deciding, that bribery was established, and still dismissed the challenge, because the integrity or validity of the award itself must be in question. The dealings were an attempt to resolve the dispute after it arose and had nothing to do with the claims the contractor won, no offence under UAE law was alleged, and no authority was shown that UAE public policy includes foreign criminal laws.

The tribunal applied the wrong law or skipped your argument: does that count?

Not by itself. In Nazeer v Noah, ARB 011/2024, the owner of two hotels argued that the tribunal should have applied Saudi law to whether an allotment agreement was valid and enforceable, and that its failure put the award in conflict with UAE public policy. The Court held that the contracts were governed by English law, as the parties had confirmed to the tribunal, and that the owner had itself told the other side, and said in closing, that enforceability under Saudi law was not in issue. Article 35, which requires the tribunal to apply the rules of law the parties chose, is non-mandatory, and Article 9 barred the owner, which had carried on knowing Saudi law was not being applied, from complaining afterwards. Even a wrong choice of law would not have conflicted with public policy, and no evidence showed any UAE public policy the award offended. Article 41 does not let a party cure the consequences of its own forensic choices.

A short answer to an argument is not a failure to deal with it either. In Olan the employer called the tribunal's treatment of its liquidated damages set-off exceptionally cursory. A tribunal must deal with the issues, the Court held, but it need not address every argument or explain each step, and dealing with an issue badly is not a ground.

Have you lost the objection by not raising it in the arbitration?

Possibly. Article 9 treats a party who knows that a provision of the Law, or a requirement of the arbitration agreement, has not been complied with, and carries on without objecting without undue delay or within any time limit, as having waived the right to object. Nazeer is the plainest example. In Muzama the Court held that a scope objection had been waived where the losing party did not object when the claim was pursued and argued the point fully, and observed that under the institutional rules that applied, waiver could be shown largely from the pleadings and submissions, without the knowledge Article 9 requires. In Lachesis the first-instance judge treated a failure to ask the tribunal under Article 40 to correct the missing signatures as a waiver, a point the Court of Appeal left open.

The limit is timing. A party cannot be said to have proceeded without objecting to something it could not have known about. In Princeton the Court called a waiver argument unarguable, because the points complained of first appeared in the award and the losing party then took the steps the law allowed within time.

If you prove a ground, can the Court still refuse to set the award aside?

In principle yes, but less often than the word 'may' in Article 41(2) suggests. Lachesis held that the provision gives the Court a discretion, and upheld its exercise against an applicant whose award had not been signed on every page as the institution's rules required, because there was no doubt every arbitrator had approved it and no prejudice was shown.

Olan set out how the discretion works. The Court asks whether there was an error within an Article 41(2) ground, and then whether, but for it, the tribunal might well have reached a different view and produced a significantly different outcome. If not, the award will almost always stand. A possible breach of the institution's rules, because no order had permitted the winning party to withdraw part of its claim, failed on that test, since the order could have been obtained at the time and the outcome would have been the same. The Court of Appeal in Oheo doubted whether the Court would realistically refuse relief where an applicant had clearly brought its case within Article 41(2)(a)(ii) or (iii), and Princeton held it probable that the Court would set aside where an error may have had a material effect on the outcome.

Can part of the award survive, or go back to the tribunal?

Part can survive where the bad part separates cleanly. Where decisions on matters submitted can be separated from those not submitted, the proviso to Article 41(2)(a)(iii) allows only the part deciding matters not submitted to be set aside. In Oheo the Court of Appeal set aside only the paragraphs of the award that gave effect to the claim the bank had no chance to answer. In Princeton the Court said it would have severed the offending parts if it could, but they were the foundation of the majority's conclusions, so deleting them would have left an award neither party wanted and no arbitrator had considered appropriate.

The alternative is remission. Article 41(4) lets the Court, where appropriate and if a party asks, suspend the set-aside proceedings so the tribunal can resume the arbitration or take other action that would eliminate the grounds. Rules 43.55 and 43.57 require the claim form and the respondent's evidence to say whether a suspension is requested. In Princeton the winner's request for confinement or remission did not save the award.

What does a failed challenge cost, and can you be made to give security?

Potentially more than an ordinary lost application. Practice Direction No. 1 of 2017 says the principle of indemnity costs may be invoked for unsuccessful applications to set aside arbitral awards. In Nazeer the Court held that an unsuccessful challenge found to have no real prospect of success justifies indemnity costs whether or not the applicant knew that at the start, because a party bringing one should make sure at the outset that it has real prospects on the law and the evidence, and must bear the risk if it does not. It called the challenge a confected public policy issue and fixed the winner's costs at USD 132,000, a case figure. Muzama ended with costs on the standard basis.

Security can come first. In Pippa v Phineas, ARB 034/2026, on 3 September 2026, the Court ordered a losing party that had brought a set-aside claim to provide AED 300,000 as security for the winner's costs within 28 days, on prima facie evidence giving reason to believe it would be unable to pay those costs, with the award unpaid and no evidence of assets against which it could be enforced. The claim was stayed until security was given, and the winner was left free to apply to dismiss it if none was provided. That figure, too, belongs to its case.

If the DIFC Court rules against you, can you appeal?

With permission. Article 41 decisions are not among those Rule 43.60 makes unappealable, and under the amended Part 44 of the Rules an appeal to the Court of Appeal needs permission, sought first from the lower Court and, if refused, from the Court of Appeal, within 21 days unless the lower Court directs otherwise. Permission needs a real prospect of success or another compelling reason, and an appeal does not stay the decision unless a court so orders.

Oheo shows the route working. The first-instance judge dismissed the bank's challenge in July 2025 and refused permission in September 2025, the Court of Appeal granted permission on a renewed application in November 2025, and the appeal succeeded in April 2026. In Princeton the winner filed an appeal notice on 4 September 2026, according to the costs ruling. Searches on 15 October 2026 found no published appellate decision in Princeton, and no costs ruling or appeal in Olan, whose consequential matters had been listed for a later hearing.

The cards restate what separated success from failure.

What should the file contain before the claim is issued?

Most of the work is fixing facts that already exist. The sequence follows what the Rules and the decisions test.

1. Fix the date the award was received, and the date any Article 40 request was disposed of, with the records that prove both.
2. Map each complaint to a ground in Article 41(2). A tribunal's errors on the facts, the law or the weight of evidence are not on the list.
3. For a fairness complaint, identify the point that decided the award, show whether it was in play, and set out what you would have argued and why it could have made a difference.
4. Check the arbitration record for every objection you raised, when you raised it, and anything you told the tribunal was not in issue.
5. Identify which parts of the award each ground affects, and decide whether to ask for a suspension under Article 41(4).
6. Put the grounds, the parts of the award challenged and the Article relied on in the claim form itself, because Rule 43.7 says a reference to a witness statement is not enough.
7. Make every other party to the arbitration a defendant, serve within 30 days of issue, and watch for a recognition order, because the 14 days under Rule 43.70 run from its service.
8. Budget for indemnity costs and a security application, and test whether the challenge has real prospects before issuing it.

What do losing parties in this position get wrong?

The recurring mistake in these decisions is spending the claim on the merits. Most of the failed challenges discussed here asked the Court to revisit what the tribunal had decided, or relied on a defect that made no difference, while both successful ones showed a decisive point decided without the losing party being heard. That is the line to test a file against before money is spent, together with the record, because what a party objected to or conceded in the arbitration shaped several of these outcomes. The second mistake is leaving a recognition order unanswered, when Olan and Princeton both show the Court managing the two claims together once it knows of both. Every source cited here was read on 15 October 2026, the Arbitration Law in its officially published consolidation of December 2013, and a search of published decisions is not a court-file certification.

Frequently Asked Questions

Is there any appeal on the merits from an award in a DIFC-seated arbitration? No. Article 41(1) makes an application to set aside the only recourse to a court against an award made in the seat of the DIFC, and the Court of Appeal in Lachesis v Lacrosse held that neither errors of law nor errors of fact by the tribunal are grounds. An appeal, with permission, lies against the DIFC Court's decision on the set-aside claim, not against the award.

Does the three months run from the date on the award? No, from the date you received it. Article 41(3) and Rule 43.54 instead run it from the date the tribunal disposed of a request under Article 40 if one was made, and allow a longer period if the parties agreed one in writing. Under the Schedule to the Law the period starts on the day after receipt.

Has the time limit been cut to 30 days? Not as at 15 October 2026. A DIFC Authority consultation published in June 2026 proposed replacing three months with 30 days in Article 41(3), and the consultation paper says the draft should not be relied on until it is formally enacted. No enactment notice for it appeared in the DIFC legal database when this guide was checked.

Does issuing a set-aside claim stop the winner enforcing the award? Not automatically. Under Rule 43.70 a recognition order made without notice cannot be enforced until 14 days after service, or until an application made in that period is finally disposed of. Beyond that the Court decides. In Olan it stayed the recognition order until the set-aside claim was determined, and in Princeton it prohibited enforcement after refusing the winner's application for security.

Can the Court reconsider how the tribunal weighed the evidence? No. Article 26(2) gives the tribunal power to determine the admissibility, relevance, materiality and weight of evidence where the parties have not agreed otherwise, and in Olan the Court treated complaints about how the tribunal handled a disputed document as challenges to its findings. The question under Article 41(2)(a)(ii) is whether you were able to present your case, not whether the tribunal accepted it.

Do I need expert evidence for a public policy challenge? Usually. The Court of Appeal in Lachesis said the DIFC Court will rarely be in a position to make findings on UAE public policy without expert evidence. In Olan the Court said a challenge without evidence must show that the award fundamentally offends the most basic principles of justice and fairness, or intolerable ignorance or corruption on the tribunal's part, and in Nazeer the absence of any evidence of a UAE public policy the award offended was one reason the challenge failed.

What if the tribunal decided the case on a point nobody argued? That is the ground on which challenges discussed here have succeeded. In Oheo Bank v Parker and Princeton v Persephone awards were set aside because the tribunal decided on points the losing party had no fair opportunity to answer, and what it would have argued could reasonably have made a difference. The winner in Princeton has since sought to appeal, and a waiver argument there failed because the points first appeared in the award.

Will I pay the other side's costs if the challenge fails? Usually, and possibly on the indemnity basis. Practice Direction No. 1 of 2017 allows indemnity costs to be invoked for unsuccessful set-aside applications, and Nazeer v Noah applied that basis to a challenge without real prospects. The Court can also require security for the winner's costs before the claim is heard, as it did in Pippa v Phineas, where the claim was stayed until security was given.
