Position of UK on Rome II after Brexit

Following the United Kingdom's departure from the European Union, a significant shift occurred in the legal landscape, particularly in the realm of international private law. Among these changes, Rome II, which pertains to non-contractual obligations in civil and commercial matters, has transitioned into what is known as retained EU law within the UK legal framework. This transition is part of the broader effort to ensure continuity and legal certainty post-Brexit by incorporating existing EU legislation into UK law, with necessary modifications to reflect the UK's new status as a non-EU country.

Rome II in the UK Post-Brexit
Rome II Regulation (EC) No 864/2007 on the law applicable to non-contractual obligations aims to determine which law applies to civil and commercial disputes involving more than one country within the EU, concerning non-contractual obligations arising out of torts (delicts), unjust enrichment, negotiorum gestio (acts performed without due authority), and culpa in contrahendo (fault in conclusion of a contract). Its primary goal is to provide predictability and fairness in cross-border disputes by establishing clear rules on the applicable law.

With Brexit, the UK faced the challenge of disentangling its legal system from the EU's while maintaining a degree of legal stability and predictability for individuals and businesses engaged in cross-border activities. To address this challenge, the European Union (Withdrawal) Act 2018 was enacted, which converts EU law as it stood at or before 23:00 (Greenwich Mean Time) on 31 January 2020 into UK domestic law. Under this framework, Rome II has been retained and continues to apply within the UK, albeit with minor amendments to ensure its operability in a non-EU context.

Impact of Retaining Rome II
The retention of Rome II signifies the UK's commitment to maintaining a coherent legal framework for determining the applicable law in cases of non-contractual obligations involving cross-border elements. This continuity is crucial for legal practitioners, businesses, and individuals involved in or affected by such disputes, providing them with a familiar basis for resolving legal uncertainties.

However, the transition also introduces complexities, especially regarding the interaction between UK and EU legal systems in the post-Brexit era. While Rome II continues to apply domestically within the UK, its interpretation and application in a UK-only context may diverge from that within the EU over time, particularly as UK courts are no longer bound by future decisions of the Court of Justice of the European Union (CJEU).

The position of the UK after Brexit, with regard to Rome II and other retained EU laws, represents a balancing act between continuity and autonomy. As the UK charts its course outside the EU, the legal community will closely monitor how retained EU laws are interpreted and adapted to fit the UK's evolving legal and commercial landscape. The minor amendments to Rome II post-Brexit exemplify the broader challenges and opportunities faced by the UK in redefining its legal relationship with the EU and the rest of the world.
