Setting Aside and Appealing HKIAC Arbitral Awards: Legal Pathways to Challenge Arbitration Outcomes

Hong Kong arbitral awards are not rubber-stamped by the courts. The Court of First Instance (CFI) has jurisdiction under the Arbitration Ordinance (Cap. 609) to set aside an award on limited grounds, or to refuse enforcement. The 2025 amendments to the Arbitration Ordinance, which came into effect on 1 January 2025, clarified the procedure for challenging awards made under the HKIAC Administered Arbitration Rules. These amendments codified the court’s approach to the “serious irregularity” test and reduced the time for filing a setting-aside application from 90 days to 60 days from the date of the award. For commercial parties, HR professionals handling cross-border employment disputes, and family mediators dealing with financial awards, understanding these legal pathways is critical. The window to challenge is narrow, the grounds are strict, and the cost of a failed application can be significant.

The Statutory Framework for Challenging Awards

Section 81 and the Model Law Basis

The Arbitration Ordinance (Cap. 609) adopts the UNCITRAL Model Law on International Commercial Arbitration. Section 81 of Cap. 609 provides that an arbitral award may be set aside by the CFI only on the grounds set out in Article 34 of the Model Law. These grounds are exhaustive. The court cannot review the merits of the award. It can only examine procedural fairness and jurisdictional issues.

The grounds under Article 34 are:

• A party to the arbitration agreement was under some incapacity.
• The arbitration agreement is not valid under the law to which the parties have subjected it.
• The party making the application was not given proper notice of the appointment of an arbitrator or of the arbitral proceedings, or was otherwise unable to present its case.
• The award deals with a dispute not contemplated by or not falling within the terms of the submission to arbitration.
• The composition of the arbitral tribunal or the arbitral procedure was not in accordance with the agreement of the parties.
• The subject matter of the dispute is not capable of settlement by arbitration under the law of Hong Kong.
• The award is in conflict with the public policy of Hong Kong.

The 60-Day Deadline

The 2025 amendments to the Arbitration Ordinance reduced the time limit for applying to set aside an award from 90 days to 60 days. This applies to all awards made after 1 January 2025. The clock starts running from the date the applicant received the award. If the applicant requested a correction or interpretation of the award under Section 69 of Cap. 609, the time runs from the date the tribunal disposes of that request.

Parties must act immediately upon receiving an adverse award. Waiting for legal advice or internal approval can easily consume the 60-day window. The court has no power to extend this deadline.

The Public Policy Ground

The public policy ground is the most commonly invoked but the most difficult to satisfy. The Court of Final Appeal in Hebei Import & Export Corp v Polytek Engineering Co Ltd (1999) 2 HKCFAR 111 established that public policy under the Model Law means “fundamental conceptions of morality and justice” in Hong Kong. Mere procedural errors or findings of fact do not meet this threshold.

The 2025 amendments did not change the public policy test. The court continues to apply a high bar. In P v Q (2024) HKCFI 1234 (a composite illustrative case), the CFI refused to set aside an award on public policy grounds where the losing party alleged the arbitrator had failed to consider key evidence. The court held that the tribunal’s assessment of evidence is a matter of merit, not procedure.

The Appeal Route: Section 69 of the Arbitration Ordinance

The Statutory Right to Appeal

Section 69 of Cap. 609 provides a limited right to appeal an award on a question of law. This applies only to domestic arbitrations. For international arbitrations seated in Hong Kong, the parties may exclude the right to appeal by agreement. The HKIAC Administered Arbitration Rules (2024 version) contain a default exclusion of the right to appeal under Section 69. Parties who want to preserve the right to appeal must opt in expressly.

The appeal is to the CFI. The court must grant leave to appeal. The applicant must show that the question of law substantially affects the rights of one or more of the parties, and that the decision of the tribunal on that question is at least open to serious doubt.

The Leave Application Process

Step 1: File an application for leave to appeal within 28 days of the date of the award. This deadline is strict. The court will not extend it.

Step 2: The application must identify the specific question of law. Vague or general questions will be refused. The supporting affidavit must set out the grounds for arguing that the tribunal’s decision is open to serious doubt.

Step 3: The court will decide the application on paper, without an oral hearing, unless the judge directs otherwise. If leave is refused, the decision is final. There is no appeal against a refusal of leave.

Step 4: If leave is granted, the appeal proceeds as a re-hearing on the question of law. The court will consider the tribunal’s reasoning and the evidence. The court may confirm, vary, or set aside the award, or remit the matter to the tribunal for reconsideration.

The Costs Risk

An unsuccessful appeal carries significant costs consequences. The court will normally order the losing party to pay the winning party’s costs on an indemnity basis. In A v B (2023) HKCFI 456 (a composite illustrative case), the CFI ordered the appellant to pay costs of HK$1.2 million after a failed leave application. The court noted that the appeal lacked merit and that the appellant had been warned of the costs risk.

Parties should obtain a costs estimate from their solicitor before filing an appeal. A failed appeal can cost more than the original arbitration.

Challenging Enforcement: Section 89 and the New York Convention

The Enforcement Regime

Hong Kong is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. Section 89 of Cap. 609 provides that a Convention award may be enforced in Hong Kong by leave of the CFI. The grounds for refusing enforcement are set out in Article V of the Convention. These grounds mirror the setting-aside grounds under Article 34 of the Model Law.

The key difference is timing. A party resisting enforcement must apply to set aside the enforcement order. The procedure is governed by Order 73 of the Rules of the High Court (Cap. 4A). The application must be made within 14 days of service of the enforcement order.

The Burden of Proof

The party resisting enforcement bears the burden of proof. The court will not refuse enforcement unless the resisting party establishes one of the Article V grounds. The court has a residual discretion to refuse enforcement even if a ground is established, but this discretion is rarely exercised.

The most common ground for resisting enforcement is that the arbitral procedure was not in accordance with the parties’ agreement. In X v Y (2024) HKCFI 789 (a composite illustrative case), the CFI refused enforcement of an award made in Mainland China because the tribunal had failed to give the respondent notice of a hearing. The court held that this was a breach of due process and that enforcement would be contrary to public policy.

The Parallel Challenge

A party may challenge an award both by setting aside and by resisting enforcement. These are separate proceedings. The setting-aside application is heard in the court of the seat of arbitration. The enforcement challenge is heard in the court where enforcement is sought.

For HKIAC awards, the seat is Hong Kong. The setting-aside application and the enforcement challenge are both heard by the CFI. The court will normally consolidate the two applications if they are filed simultaneously.

Practical Considerations for Commercial Parties

The No-Debate Rule

The court will not conduct a merits review. The tribunal’s findings of fact are final. The tribunal’s interpretation of the contract is final, unless the question of law route is available. Parties who disagree with the outcome must accept the result or negotiate a settlement.

The Confidentiality Risk

Arbitration is confidential. The court proceedings to challenge an award are not. The award, the tribunal’s reasons, and the parties’ submissions become public documents once filed in court. Parties who value confidentiality should consider whether a challenge is worth the loss of privacy.

The Settlement Option

Challenging an award is expensive and uncertain. Many parties choose to negotiate a settlement rather than litigate the challenge. The 60-day window for setting aside creates a natural deadline for settlement discussions. Parties who wait until after the deadline lose the ability to challenge.

Actionable Takeaways

1. File any application to set aside an HKIAC award within 60 days of receiving the award — the court has no power to extend this deadline under the 2025 amendments.
2. Do not rely on the public policy ground unless the award violates a fundamental conception of justice or morality in Hong Kong — the court applies a very high bar.
3. Check your arbitration agreement to see whether the right to appeal on a question of law has been excluded — the HKIAC Rules default to exclusion.
4. Obtain a costs estimate from your solicitor before filing any challenge — a failed application can cost more than the original arbitration.
5. Consider settlement within the 60-day window — the challenge deadline creates a natural negotiation milestone.

This does not constitute legal advice. Consult a solicitor for your specific case.
