What this guide covers
A DIAC arbitral award can only be challenged by set-aside — not by appeal on the merits. UAE Federal Arbitration Law FDL 6/2018 Arts 53–54 provide the exclusive exhaustive grounds, a strict 30-day deadline, and a narrow judicial review standard. Both attacking and defending awards require mastery of this framework.
The seven grounds for set-aside under FDL 6/2018 Art 53
Set-aside is available only on one or more of seven exhaustive grounds (Art 53(1)). The applicant bears the burden of proving the ground applies:
(a) Incapacity or invalid agreement: A party to the arbitration agreement was under a legal incapacity, or the agreement is null and void under the law to which the parties subjected it, or in the absence of a choice, under UAE law.
(b) Improper notification: The party was not given proper notice of appointment of the arbitrator, the arbitration proceedings, or was otherwise unable to present its case — a fundamental due process breach.
(c) Subject matter not covered: The award deals with a dispute falling outside the scope of the arbitration agreement or outside the submissions made to the tribunal. Courts distinguish carefully between decisions on issues submitted (valid) and decisions on issues not submitted (void).
(d) Tribunal constitution or procedure: The composition of the arbitral tribunal or the arbitral procedure was not in accordance with the parties' agreement (unless that agreement conflicts with a mandatory provision of the Law), or in the absence of agreement, in accordance with the Law.
(e) Not yet binding, suspended or set aside: The award has not yet become binding, or has been suspended or set aside by a court of the country of the seat.
(f) Arbitrability: The subject matter of the dispute is not capable of settlement by arbitration under UAE law — certain disputes (criminal, personal status, certain real estate rights) cannot be arbitrated.
(g) Public policy: The award is in conflict with the public policy of the UAE. This is construed narrowly by UAE courts — mere inconsistency with a UAE law provision is not enough; the violation must be fundamental to the social and economic order of the UAE. Courts have refused set-aside based on alleged Sharia inconsistency where the award involved commercial parties.
Procedure and 30-day deadline
Set-aside application is filed with the court of competent jurisdiction at the seat: Dubai Court of Appeal for Dubai-seated DIAC awards; Abu Dhabi Court of Appeal for Abu Dhabi-seated awards; DIFC Court of First Instance for DIFC-seated DIAC awards. The applicant must file within 30 days of receipt of the award (Art 54.1). The 30-day limit is strict — UAE courts have consistently refused late applications. The limit cannot be extended by agreement.
Filing an application does not automatically stay enforcement unless the court separately orders a stay. The award winner may continue enforcement proceedings during the set-aside challenge, unless the court grants a stay. Seeking a stay is important — if enforcement completes while set-aside is pending, the set-aside application becomes academic.
The competent court decides the application without re-examining the merits of the award. It is not an appeal — the court applies a deferential standard of review, limited to the seven listed grounds. Dubai Court of Appeal has developed extensive jurisprudence on each ground.
The public policy ground in UAE practice
Public policy (Art 53(1)(g) and Art 57(2)(b)) is the most frequently invoked ground and the most frequently rejected by UAE courts. The UAE Federal Court of Cassation has consistently held that public policy means fundamental principles of the UAE legal and social order — not every departure from a domestic law provision. Grounds regularly rejected as public policy include: award of interest (conventional interest is permitted in commercial matters despite Islamic prohibition on riba — the courts distinguish commercial and personal transactions); failure to apply UAE law on substantive issues; and procedural deviations not rising to fundamental breach.
Grounds occasionally accepted as public policy: award involving gambling contracts; award against mandatory UAE labour law protections; award involving a matter reserved exclusively to UAE courts by express statutory provision (e.g., certain RERA-mandated disputes).
Practical checklist
- Diarise 30-day set-aside deadline from the date of receiving the award — this is the single most important deadline in the entire process
- File an application for stay of enforcement simultaneously with the set-aside application — do not allow enforcement to complete while challenging
- Assess grounds objectively: UAE courts apply narrow review; pursue only grounds with solid evidentiary support
- Document notification irregularities during proceedings — procedural breach must be raised promptly during proceedings or it may be waived
- For public policy ground: cite specific UAE Federal Court of Cassation authority supporting the ground; do not rely on general policy arguments
- Consider strategic implications: a failed set-aside application can delay enforcement by 12–18 months even when ultimately dismissed
What we'd typically advise
We advise clients facing a set-aside application to resist it aggressively from the outset — move to dismiss on jurisdiction (no ground arguable), seek security as a condition of the stay, and pursue parallel enforcement in other jurisdictions where the debtor has assets. The DIFC conduit mechanism allows enforcement to begin in parallel even while a Dubai Court set-aside application is pending. An award creditor who moves quickly across multiple jurisdictions often collects before the set-aside is decided.
Frequently asked questions
Can I challenge a DIAC award on the merits — for example, because the tribunal made a legal error?
No. UAE courts do not review the merits or legal correctness of arbitral awards on set-aside. The only recourse is one of the seven grounds in Art 53. A legally incorrect award is not voidable on that basis alone. This is a fundamental feature of the pro-arbitration framework.
What happens to the award if the set-aside application succeeds?
The court annuls the award in whole or in part. The parties then face a choice: re-arbitrate the dispute from the beginning (the arbitration agreement survives unless it was itself the basis for set-aside), or settle. There is no automatic referral back to the original tribunal.
Can a party waive the right to set aside?
Parties can limit (but not entirely exclude) set-aside rights. Some institutional rules and some national laws allow parties to agree to exclude certain set-aside grounds. Under UAE law, the ground of public policy cannot be waived. Other grounds can be waived implicitly by failing to raise them during proceedings.
Does DIFC offer a different set-aside procedure for DIFC-seated DIAC awards?
Yes. DIFC-seated awards are challenged in the DIFC Court under DIFC Arbitration Law Art 41. The DIFC Court applies the UNCITRAL Model Law grounds (Art 34) which are essentially identical to FDL 6/2018 grounds. DIFC has a 90-day window from receipt of the award — three times longer than the UAE onshore 30 days.
Is there any appeal from the court's set-aside decision?
Yes. Under UAE onshore procedure, the Dubai Court of Appeal decision can be appealed to the Dubai Court of Cassation. The Court of Cassation reviews only questions of law. DIFC Court of First Instance decisions can be appealed to the DIFC Court of Appeal.
