The AIFC Court's July 2026 ruling in Naftogaz v Gazprom (AIFC-C/CFI/2026/0002) confirmed that the court does not have jurisdiction to recognise and enforce awards made in foreign-seated arbitrations, reversing an earlier enforcement order and creating a significant procedural boundary for international creditors in Kazakhstan. Parties seeking to enforce foreign arbitral awards against assets located in the country must proceed through the Kazakhstan state courts under the New York Convention, not through the AIFC Court. This distinction matters greatly for litigation strategy, enforcement timelines and asset-freezing options in any cross-border dispute involving Kazakhstan-based counterparties.
What Happened in Naftogaz v Gazprom: A Procedural Chronology
The case arose from an ICC arbitration seated in Switzerland, where a final award of approximately USD 1.4 billion was issued on 16 June 2025. The claimant, Naftogaz, applied to the AIFC Court for recognition and enforcement of that award. On 15 May 2026, Justice Andrew Spink KC granted the enforcement order, treating the AIFC Court's common-law jurisdiction and its international judicial composition as a sufficient basis for entertaining the application.
Less than two months later, on 7 July 2026, Lord Faulks KC set that order aside. The ruling turned on a fundamental point: the AIFC Court's constitutive framework does not extend to enforcement of awards rendered outside its own institutional perimeter. The court, in other words, recognised that its jurisdiction is defined by statute and by the AIFC's founding instruments, not by the breadth of its common-law tradition or the international credentials of its bench.
The Kazakhstan Ministry of Justice reinforced this reading with a public statement that the AIFC Court is not part of the state court system. That institutional separation, which is the foundation of the AIFC's attractiveness for commercial disputes seated within the financial centre, simultaneously represents the ceiling of its authority when foreign-seated proceedings are concerned.
The Legal Framework: Two Parallel Systems in One Country
Kazakhstan operates, in effect, two distinct legal environments for international commercial dispute resolution. Understanding their interaction is essential before any enforcement strategy is designed.
The first environment is the AIFC ecosystem. Established under the Astana International Financial Centre framework, the AIFC Court applies English common law principles, conducts proceedings in English and is staffed by international judges drawn from common-law jurisdictions. The AIFC International Arbitration Centre (IAC) and the AFSA regulatory body operate alongside it. This ecosystem was designed to give financial and investment transactions within the AIFC the predictability of an internationally recognised legal system, free from the civil-law procedures of Kazakhstan's domestic courts.
The second environment is the state court system, which applies the Civil Procedure Code of Kazakhstan and Kazakhstan's obligations under international treaties, including the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. Foreign arbitral awards – those issued by tribunals seated outside the AIFC – fall within this second regime, not the first.
The Naftogaz v Gazprom ruling does not undermine the AIFC ecosystem's authority over disputes that belong to it. What it does is draw a line: a Swiss-seated ICC award is a foreign award. Its enforcement must travel through the New York Convention route in the state courts, regardless of how closely the creditor's claim or the debtor's assets may relate to AIFC-registered entities.
Open Questions the Ruling Leaves Unanswered
While the jurisdictional point is now settled with reasonable clarity, the ruling generates a series of subsidiary questions that practitioners advising clients on debt collection and payment order enforcement in Kazakhstan will need to address case by case.
- Seat-adjacent awards. Where an award is issued by the IAC itself, the AIFC Court's enforcement jurisdiction is uncontroversial. The boundary question concerns awards where arbitration was conducted under AIFC-linked rules but with a seat technically located outside the centre. The ruling does not map this boundary with precision.
- Asset-freezing applications. A creditor who cannot use the AIFC Court to enforce a foreign award may nonetheless wish to apply for interim asset-freezing measures against Kazakhstan-situated assets during recognition proceedings in the state courts. Whether the AIFC Court could entertain a standalone freezing application as an ancillary matter – given the Ministry of Justice's statement about institutional separation – is not resolved.
- Parallel proceedings risk. A creditor who, following the May 2026 order, took steps in reliance on the then-valid enforcement order faces a procedural gap now that it has been set aside. Limitation periods and priority positions in the state court system may have shifted in the intervening weeks.
- Late payment interest accrual. Kazakhstan's state courts apply their own rules on late payment interest under domestic civil law. Where an ICC or other foreign tribunal has awarded interest at a contractually agreed rate, the state court recognition process may engage questions about which interest calculation governs post-award accumulation and at what rate – a detail that affects the total sum recoverable on an unpaid invoice.
- Recognition versus enforcement. Kazakhstan's New York Convention implementation, like that of most signatories, treats recognition and enforcement as conceptually distinct steps. A creditor may obtain recognition of an award without immediately proceeding to active enforcement; but the procedural pathway for each step, and the defences available at each stage, deserve careful mapping before the application is filed.
Practical Impact: What International Creditors Must Reconsider
For companies and funds that hold foreign arbitral awards against Kazakhstan-based counterparties – whether arising from energy contracts, trade finance, construction disputes or financial services arrangements – the ruling requires a reassessment of enforcement strategy. The AIFC Court is not a shortcut to enforcement. The state court route, while procedurally more demanding and conducted in Kazakh or Russian, is the legally prescribed pathway.
Several practical considerations follow from this reorientation.
- Jurisdiction planning at the contract stage. Parties drafting commercial agreements with Kazakhstan counterparties should consider carefully whether to use IAC arbitration (AIFC-seated) rather than ICC, LCIA or other internationally prominent institutions with foreign seats, if enforcement within Kazakhstan is a realistic concern. The seat choice now carries concrete procedural consequences.
- Asset identification before filing. Enforcement proceedings in the state courts require that the creditor identify assets against which execution can be levied. A thorough pre-filing asset tracing exercise – covering bank accounts, real property, shareholdings in Kazakh entities and receivables – significantly affects the practical utility of a recognition order.
- Interaction with sanctions and trade controls. In cases involving counterparties subject to sanctions or where payment flows implicate export control considerations, the enforcement route intersects with a separate layer of legal risk. Creditors should review their position under applicable sanctions frameworks before commencing enforcement. For background on how sanctions considerations affect cross-border recovery strategies, see our analysis at Ferraz & Whitmore – Sanctions and Trade Controls: Kazakhstan.
- Coordination with Portuguese and EU proceedings. Where assets or principals have a European nexus – which is common in energy, infrastructure and financial services transactions – parallel proceedings in EU jurisdictions may complement Kazakhstan state court enforcement. Coordinating timelines, avoiding res judicata complications and maximising recoverable amounts across jurisdictions requires careful sequencing.

Cross-Border Implications: Kazakhstan, AIFC and the Wider Enforcement Landscape
The ruling also carries implications beyond Kazakhstan's borders. The AIFC Court was widely positioned, from its inception, as a vehicle for integrating Central Asian commercial activity into globally recognised legal infrastructure. Its common-law pedigree and experienced international bench attracted genuine interest from foreign investors who preferred the predictability of English-law principles over the civil-law procedures of domestic courts in the region.
The July 2026 decision does not diminish those attributes for disputes that properly belong before the AIFC Court. What it does is clarify that the AIFC Court's common-law framework is not a general-purpose enforcement forum for the global arbitration community. That role belongs to the state courts through the New York Convention machinery.
In comparative terms, this is not an unusual position. Many specialist commercial courts – including financial centre courts in other jurisdictions – operate with defined subject-matter or institutional perimeters. The question for the AIFC Court is how clearly those perimeters will be drawn in future cases, and whether the institutional framework will evolve to address the gap the ruling has exposed.
For a broader perspective on how other jurisdictions handle the interaction between specialist arbitration courts and general enforcement regimes, the firm's analysis of Japan's 2024 arbitration reforms and award enforcement offers useful comparative context.
Strategic Recommendations for Clients with Kazakhstan Exposure
Drawing together the legal analysis and practical observations above, the following considerations represent a working framework for companies and funds reassessing their Kazakhstan dispute resolution and debt recovery strategies.
- Audit existing contracts. Identify which arbitration clauses specify a foreign seat and which specify the AIFC IAC. The enforcement consequences differ materially.
- Review pending AIFC Court applications. Any enforcement application filed before the July 2026 ruling that relied on the May 2026 reasoning should be reviewed immediately for procedural sustainability.
- Engage Kazakhstan-qualified counsel early. State court proceedings for New York Convention enforcement require local counsel with procedural expertise in Kazakhstan civil procedure. Early engagement avoids errors at the filing stage that can delay recognition.
- Consider the asset landscape holistically. Where a counterparty has assets in multiple jurisdictions, a coordinated multi-jurisdictional enforcement strategy, using the most efficient recognition route in each jurisdiction, will often produce better outcomes than a single-forum approach.
- Renegotiate where possible. In ongoing commercial relationships, parties may find it more efficient to renegotiate dispute resolution clauses to specify AIFC IAC arbitration rather than rely on foreign-seated institutions, where enforcement in Kazakhstan is a priority concern.
- Document the debt trail. For debt collection and enforcement of unpaid invoices, a clear, uninterrupted paper trail – purchase orders, delivery records, payment demands, contractual terms – remains the foundation of any enforcement application, regardless of which court system is engaged.

Outlook: What May Change and What Will Not
The jurisdictional boundary established by the July 2026 ruling is based on the AIFC Court's founding instruments and on Kazakhstan's parallel state court framework. Changes to that boundary would require either legislative amendment to the AIFC's constitutive rules, a treaty-level agreement extending the court's remit, or a higher-court decision revisiting the reasoning of Lord Faulks KC. None of these is imminent on the basis of publicly available information.
What may evolve more quickly is the AIFC Court's jurisprudence on adjacent questions: the scope of interim measures in support of foreign proceedings, the treatment of AIFC-connected awards with hybrid seat arrangements, and the recognition of consent orders or settlement agreements made in foreign proceedings. These are areas where the boundary remains to be tested.
For institutional users of the AIFC – investment funds, financial institutions and major corporates operating within the financial centre – the ruling serves as a practical reminder that the legal architecture of the AIFC, however sophisticated, is not co-extensive with the full range of international enforcement needs. Structuring transactions and dispute resolution clauses with that distinction in mind is prudent rather than merely cautious.
