Using synthetic proceedings in cross-border insolvency: Opportunities and challenges

Cross-border insolvency cases often require opening of insolvency proceedings in and coordination amongst multiple jurisdictions, leading to increased complexity, costs, and delays. Synthetic proceedings have emerged as a tool to address some of these challenges by allowing a domestic court to apply foreign law within its own insolvency process, thereby reducing the need for multiple ancillary proceedings in other jurisdictions.
Ashurst's Rob Child and Shreya Prakash have authored an INSOL International Technical Paper that explores the origins, benefits, applications, challenges, and recommended reforms related to synthetic proceedings. This article summarises their findings.
Synthetic proceedings enable a domestic insolvency court to apply foreign law—most commonly, the distributional priorities of another jurisdiction—within the insolvency proceeding it is supervising. This approach is designed to replicate the effect of opening secondary proceedings in other countries, but without the associated costs and procedural burdens.
The classic use of synthetic proceedings has been seen in high-profile English cases such as Re Collins & Aikman, Re MG Rover, and Re Nortel Networks. In these cases, English courts permitted administrators to make distributions to certain creditors in accordance with foreign law, provided that the approach was supported by the majority of creditors. This avoided the need to open costly and time-consuming secondary proceedings in other countries.
Inspired by English practice and given the abovementioned benefits, the use of "synthetic" proceedings has been promoted as a more efficient and value-maximising alternative to the opening of ancillary proceedings. Two key initiatives to adopt synthetic proceedings have been implemented by the European Union and United Nations Commission on International Trade Law (UNCITRAL):
While traditionally used to address creditor priority issues, synthetic proceedings have potential for broader application. At their core, synthetic proceedings enable a domestic court to apply foreign law within a single insolvency process, thereby avoiding the need to open multiple ancillary proceedings in different jurisdictions. As such, any issue in cross-border insolvency that involves a "choice of law" debate and could affect distributional outcomes may be suitable for synthetic proceedings. This includes, for example, the adoption or termination of contracts, the application of foreign law to avoidance actions, and the scope of releases in restructuring plans.
Despite their advantages, synthetic proceedings face several obstacles:
Whilst it may not be possible or desirable to entirely replace ancillary proceedings, policy-makers, judges and practitioners should consider ways to promote the use of synthetic proceedings where there is broad consensus that such use would be value-maximising, and there is no fundamental incompatibility between insolvency regimes applicable to domestic proceedings and possible ancillary proceedings.
Synthetic proceedings offer a promising avenue for streamlining cross-border insolvency cases, reducing costs, and maximizing value for stakeholders. While not a panacea, and subject to legal and practical limitations, they represent a valuable tool for businesses, insolvency professionals, and policymakers seeking efficient and effective global restructurings. Ongoing reforms and increased judicial and practitioner engagement are key to unlocking their full potential.
