Irreconcilable Decisions and Corruption Allegations in International Arbitration: The Paris Court of Appeal Upholds the ICC Award in KFZO

Facts and Procedural Background

On 25 November 2025, the Paris Court of Appeal dismissed an application to set aside an arbitral award rendered on 10 March 2022 under the ICC Rules in a dispute between the Kish Free Zone Organization ("KFZO"), an Iranian public authority, and Flower of the East Kish Development Company ("FoE"), together with its shareholder, Mr E.

The dispute arose from a contract concluded on 16 July 2002, amended on 30 May 2007, under which KFZO undertook to provide land on Kish Island for the development of a luxury resort project known as Flower of the East. Mr E assigned his contractual rights to FoE in December 2003. Pursuant to the contract, FoE provided a guarantee for the purchase price and other potential claims. In January 2009, KFZO notified FoE and Mr E of its decision to terminate the contracts, citing alleged failures to finalise financing arrangements.

In November 2009, FoE and Mr E commenced ICC arbitration, seeking a declaration that the termination was ineffective and claiming damages for KFZO’s contractual breaches, including its failure to make the land available and to cooperate with the project. Subsequently, FoE and Mr E issued their own notice of termination, relying on KFZO’s alleged prior contractual breaches and its attempt to terminate the contracts.

After an arbitration that lasted almost 12 years due to various procedural reasons (including an 18-month suspension for settlement negotiations that ultimately failed), the arbitral tribunal held that FoE and Mr E were parties to the contracts and had validly terminated them following KFZO’s contractual breaches and its illegal termination. The tribunal ordered KFZO to pay approximately €39.5 million in damages, together with arbitration costs, and to return a bank cheque issued in Iran.

KFZO applied to set aside the award under Articles 1520(5) and, subsidiarily, 1520(3) of the French Code of Civil Procedure ("CPC"), alleging a violation of international public policy and an excess of the Tribunal’s mandate. The Paris Court of Appeal rejected the application in its entirety and granted exequatur to the award under Article 1527 CPC.

The Court’s Reasoning

Violation of International Public Policy

KFZO relied on two public policy arguments.

First, it contended that the arbitral award was irreconcilable with a final judgment of the Kish Island Court dated 15 August 2016, which annulled the contracts and ordered restitution of the land. KFZO emphasised that proceedings for recognition of that judgment were pending in France. The Court rejected this, recalling that a conflict with international public policy arises only once a foreign judgment has been recognised or declared enforceable in France. Since the Iranian judgment had not been granted exequatur, its coexistence with the arbitral award could not create legally irreconcilable effects.

Second, KFZO alleged that the award resulted from criminal activity, including corruption and collusion, relying on Iranian criminal judgments against KFZO officials and a German criminal judgment convicting Mr E of fraud. The Court reiterated that annulment on public policy grounds requires ‘serious, precise, and converging indicia’ demonstrating that recognition or enforcement of the award would give force to a contract obtained through corruption or allow a party to benefit from the proceeds of such activities. The Court found that KFZO had failed to establish the existence of such indicia and, consequently, failed to demonstrate that enforcement of the award would produce either result.

Both counts of the public policy challenge were therefore dismissed.

Exceeding the Tribunal’s Mandate

As a subsidiary ground, KFZO claimed that the tribunal exceeded its mandate by misapplying Iranian law in the assessment of damages and by failing to appoint a financial expert. The Court rejected this argument, holding that the tribunal had applied Iranian law, examined the claims, and explained its discretionary damages methodology. KFZO’s arguments merely challenged the tribunal’s reasoning and quantum assessment and thus sought an impermissible review of the merits. The ground was therefore dismissed.

Analysis

Irreconcilability, Exequatur, and International Public Policy

The Court’s treatment of irreconcilability is fully consistent with its established jurisprudence, recently reaffirmed in Société Nationale d’Électricité (SNEL) v. Democratic Republic of Congo (Cour d'appel de Paris, 16 September 2025, No. 24/18542). In SNEL, the Court clarified that irreconcilability between an arbitral award and a non-EU foreign judgment breaches international public policy only where the foreign judgment has been recognised in France and the coexistence of the two decisions produces mutually exclusive legal effects.

Corruption, Maximalist Approach, and the Evidentiary Threshold

The judgment further consolidates the French courts’ well-established jurisprudence on corruption allegations in international arbitration. It reaffirms that the prohibition of corruption and money laundering forms part of French international public policy, reflecting an international consensus embodied, inter alia, in the United Nations Convention against Corruption.

Since Belokon v. Kyrgyzstan (Cour d'appel de Paris, 21 February 2017, No. 15/01650), expressly endorsed by the Cour de cassation in 2022 (Cass. civ. 1re, 23 March 2022, No. 20-17.789), and further developed in Sorelec (Cour d'appel de Paris 17 November 2020, No. 18/07347), as subsequently confirmed by the Cour de cassation (Cass. civ. 1re, 7 September 2022, No. 20-22.118), French courts have embraced a so-called ‘maximalist’ approach to international public policy review (previously discussed on the Blog here and here). Under this approach, courts are neither limited to the evidence produced before the arbitral tribunal nor bound by the tribunal’s findings or legal characterisations. At the same time, the French courts apply a high standard that requires ‘serious, precise, and converging indicia’ demonstrating that recognition or enforcement of the award would allow a party to benefit from the proceeds of criminal conduct.

The KFZO judgment exemplifies this approach. The Paris Court of Appeal conducted an independent examination of the arguments, asserting that the claims arising from the award constituted the proceeds of criminal offenses. KFZO’s arguments regarding favourable financial terms, deficient contractual guarantees, procedural irregularities in contract formation, and suspicions concerning public officials were each examined in full but ultimately rejected as insufficient. Contextual factors—such as the parties’ long-standing commercial relationship, the amendment of the contract at the direction of the Iranian President, and the exceptionally late emergence of collusion allegations during a twelve-year arbitration—were also determinative in shaping the Court’s assessment.

The requirement for "serious, precise and converging indicia" is particularly evident in the Court’s treatment of allegedly ‘abnormally advantageous’ contractual terms. While the Tehran Court of Appeal had characterised the contractual price as ‘insignificant’ by reference to other land transfers on Kish Island, the Paris Court of Appeal refused to treat that characterisation as a proxy for corruption. It emphasised both the heterogeneity of the comparator transactions and the applicant’s failure to produce any concrete evidence demonstrating that those contracts were genuinely comparable in terms of their subject matter and reciprocal obligations. In doing so, the Court reaffirmed that allegations of favourable pricing, even when echoed by domestic judicial findings, do not amount to ‘serious, precise, and converging indicia’ of corruption absent a rigorous, transaction-specific evidentiary showing. This reasoning aligns with GVC v. Guinea & ARPT (Cour d'appel de Paris, 7 September 2021, No. 19/17531), where the court clarified that there is no presumption that an ‘unbalanced contract’ is necessarily corrupt.

The Court’s reasoning also reflects a heightened sensitivity to procedural consistency in corruption allegations. It noted that during the arbitration, the applicant did not rely on the alleged absence of contractual guarantees as evidence of criminal collusion but instead framed the claim as a failure by the defendants to perform a contractual obligation. Although allegations of corruption cannot be deemed waived even if not raised timely during arbitration, claims raised only after an unfavourable award—especially when they recharacterize previously pleaded facts—are unlikely to satisfy the threshold of ‘serious, precise, and converging indicia’. In Esisco, the Paris Court of Appeal (5 December 2023, No. 22/20051) rejected a corruption claim based on foreign criminal judgments because the party presented those judgments to the arbitral tribunal without alleging forgery and only raised the claim of forgery at the annulment stage, without explaining the delay. This shows that consistency in articulating corruption claims is crucial to their credibility and the success of annulment applications.

The KFZO decision is also instructive in distinguishing domestic criminal or administrative characterizations from the international public policy review under Article 1520(5) CPC. The Court stressed that, in annulment proceedings, its task is not to assess criminal liability under national law, but only whether enforcing the award would undermine the fight against corruption by allowing a party to benefit from its proceeds.

Against that backdrop, the Court found that the Iranian courts’ findings of ‘collusion in public transactions’, grounded in domestic legal and religious concepts of unjust enrichment and public probity, did not constitute corruption under international public policy. In particular, the characterization of ‘collusion’, based on the general conduct of public officials who failed to safeguard State assets, does not lead to the identification of ‘serious, precise, and consistent’ indicia of corruption that would have tainted the Contract at the time of its conclusion.

Further, the German criminal conviction of Mr. E, which concerned fraudulent conduct unrelated to the contracts, was not considered a relevant "red flag". This approach aligns with the cautious stance of French courts regarding foreign criminal judgments in corruption cases. In the Alexander Brothers v. Alstom, the Versailles Court of Appeal (14  March 2023,  No. 21/06191) held that the mere conviction of individuals involved in contract negotiations for corruption offences—when unrelated to the contracts at issue or the arbitral parties—does not constitute serious and precise indicia of corruption.

Deference to Arbitral Discretion

Finally, the decision underscores the deference afforded to arbitral tribunals under French law in the quantification of damages. The Court reaffirmed that challenges to the tribunal’s reasoning or valuation methodology fall outside judicial review. This reasoning aligns with recent authority of the Cour de cassation (1re civ., 9 October 2024, No. 23-13.599), which confirmed that while the principle of adversarial proceedings requires parties to have the opportunity to debate the relevant facts and evidence, it does not require prior validation of the arbitrators’ reasoning or calculation methods.

Conclusion

The Paris Court of Appeal’s decision in the KFZO case illustrates how French courts address allegations of corruption at the annulment stage. While French courts take corruption seriously, annulment remains an exceptional remedy: parties must provide serious and precise indicia showing that enforcing the award would violate French international public policy. The Court also confirmed that unrecognised non-EU foreign judgments, on their own, do not justify annulment, and that arbitral tribunals’ damages quantification will generally be respected. Overall, the judgment reinforces two complementary principles: a firm stance against corruption and a disciplined evidentiary framework that discourages opportunistic claims.
