Hong Kong Court Reaffirms Finality of Arbitration and Curtails Collateral Attacks on Arbitral Awards

In G v CNG & SIL, the Hong Kong Court of First Instance granted an anti‑arbitration injunction to restrain a newly commenced arbitration that sought to undermine existing arbitral awards and refused to stay enforcement of those awards. The decision is a robust reaffirmation of Hong Kong’s pro‑arbitration framework and confirms that allegations of fraud or bribery cannot be used to bypass the exclusive statutory regime for challenging arbitral awards.

Background

This decision represents the latest chapter in a protracted series of arbitral and court proceedings between China National Gold Group Hong Kong Resources Co Ltd ("CNG") and two affiliates of the G Group (together, the "G Parties") arising out of a shareholders’ dispute concerning a mining project. The underlying HKIAC arbitration was commenced by the G Parties in November 2020 and has since generated multiple partial final awards. CNG has repeatedly sought to challenge or derail those awards through proceedings before the Hong Kong courts and elsewhere.

• In February 2024, the Hong Kong Court of First Instance dismissed CNG’s application to set aside the first partial final award, reaffirming the limited and exceptional nature of challenges under section 81 of the Arbitration Ordinance.
• In August 2025, the Court again rejected CNG’s attempts to intervene in the arbitral process, dismissing both an application to remove the presiding arbitrator for alleged apparent bias and a related application to set aside a further partial final award. Please refer to our earlier briefing (here) on this.

Against that backdrop, the present decision addresses CNG’s latest attempt to resist enforcement of the awards by commencing a fresh arbitration based on allegations of bribery and fraud, which the Court characterised as an impermissible collateral attack on awards that remain valid and binding.

The “bribery arbitration”

In mid 2025, after enforcement proceedings were well advanced, CNG commenced a new HKIAC arbitration alleging that: (i) the underlying share sale and shareholders’ agreements had been procured by bribery and fraud; and (ii) the arbitral awards were tainted and liable to be set aside.

The relief sought included rescission of the underlying share purchase agreement and shareholders' agreement, damages, and declarations that would have effectively undermined the legal and practical effect of the existing arbitral awards. CNG also applied to stay enforcement of the awards pending the outcome of this new arbitration and related investigations.

The G Parties applied to the Hong Kong Court for an anti arbitration injunction restraining the new arbitration.

The Court’s decision

The Court (Mimmie Chan J) held that:

1. The new arbitration was an impermissible collateral attack on existing arbitral awards and must be restrained by an anti arbitration injunction.
2. Enforcement of the arbitral awards should not be stayed.
3. CNG was ordered to pay indemnity costs, with a certificate for three counsel.

Key Reasoning

Exclusive statutory route to challenge arbitral awards

The Court emphasised that section 81 of the Arbitration Ordinance (Cap. 609), which gives effect to Article 34 of the UNCITRAL Model Law, provides the sole and exclusive mechanism for challenging arbitral awards. This exclusivity extends beyond formal setting aside applications to include any indirect attempt to impeach or undermine an award.

Importantly, the Court confirmed that allegations of fraud or bribery do not create an alternative route outside the statutory framework, nor do they relax the strict three month time limit for bringing a setting aside application.

Substance over form

Although the new arbitration was framed as asserting contractual and tortious claims (including rescission and damages), the Court examined the substance and practical effect of the relief sought. It concluded that the claims were fundamentally inconsistent with the existing awards and were designed to negate their effect.

Abuse of process

The Court found that the timing and context of the new arbitration (commenced only after enforcement pressure intensified) formed part of a broader pattern of resistance and amounted to an abuse of process. Allegations of fraud cannot be deployed as an “open sesame” to reopen disputes that have already been finally determined.

Takeaways

The judgment underscores the Hong Kong courts’ firm commitment to upholding arbitral awards and provides clear lessons on the limits of post award challenges.

• Arbitral finality remains a cornerstone of Hong Kong arbitration: The Court reaffirmed that parties who agree to arbitration are bound by the outcome, subject only to the narrow and exclusive statutory grounds for challenge.
• Allegations of fraud do not provide a backdoor to reopen awards: Claims of bribery or fraud do not circumvent section 81 of the Arbitration Ordinance, nor do they revive challenges that are out of time.
• Anti arbitration injunctions are available where necessary to protect awards: Hong Kong courts will intervene to restrain new arbitrations that, in substance, amount to non compliant or abusive attempts to undermine existing awards.
• Substance prevails over form: The Court will look beyond the drafting of claims and assess their practical effect, particularly where relief sought is inconsistent with, or designed to negate, binding arbitral awards.
• Consistency of conduct matters: Parties who have affirmed contractual arrangements and arbitral awards through their conduct will not be permitted to seek to unwind them opportunistically when enforcement pressure intensifies.
