No Sunset of Retained EU Conflict of Laws in the UK, but Increased Risk of Sunburn
By Dr Johannes Ungerer, University of Oxford
The sunset of retained EU law in the UK has begun: the Retained EU Law (Revocation and Reform) Act 2023 received Royal Assent at the end of June. The Act will revoke many EU laws that have so far been retained in the UK by the end of 2023.
The good news for the conflict of laws is that the retained Rome I and II Regulations are not included in the long list of EU legal instruments which are affected by the mass-revocation. Both Regulations have been retained in the UK post-Brexit by section 3 of the European Union (Withdrawal) Act 2018 and were modified by the Law Applicable to Contractual Obligations and Non-Contractual Obligations (Amendment etc.) (EU Exit) Regulations 2019 (as amended in 2020). The retained (modified) Rome I and II Regulations will thus be part of domestic law beyond the end of 2023. Yet this retained EU law must not be called by name anymore: it will be called “assimilated law” according to section 5 of the Retained EU Law (Revocation and Reform) Act 2023 (although the title of this enactment, like others, will strangely continue to contain the phrase “Retained EU Law” and will not be changed to “Assimilated Law”, see section 5(5)).
