Views and News from the 9th Journal of Private International Law Conference 2023 in Singapore
Four years after the 8th JPIL conference in Munich, the global community of PIL scholars finally got another opportunity to exchange thoughts and ideas, this time at Singapore Management University on the kind invitation of our co-editor Adeline Chong.

The conference was kicked off by a keynote speech by Justice Philip Jeyaretnam (Singapore International Commercial Court), providing an in-depth analysis of the Court of Appeal’s decision in Anupam Mittal v Westbridge Ventures II [2023] SGCA 1 (discussed in more detail here).
The keynote was followed by a total of 23 panels and four plenary sessions, a selection of which is summarised below by our editors.
The EU Sustainability Directive and Jurisdiction
The Draft for a Corporate Sustainable Due Diligence Directive currently contains no rules on jurisdiction. This creates inconsistencies between the scope of application of the Draft Directive and existing jurisdictional law, both on the EU level and on the domestic level, and can lead to an enforcement gap: EU companies may be able to escape the existing EU jurisdiction; non-EU companies may even not be subject to such jurisdiction. Effectivity requires closing that gap, and we propose ways in which this could be achieved.

- The Proposal for a Directive on Corporate Sustainability Due Diligence
The process towards an EU Corporate Sustainability Due Diligence Directive is gaining momentum. The EU Commission published a long awaited Proposal for a Directive on Corporate Sustainability Due Diligence (CSDDD), COM(2022) 71 final, on 23 February 2022; the EU Council adopted its negotiation position on 1 December 2022; and now, the EU Parliament has suggested amendments to this Draft Directive on 1 June 2023. The EU Parliament has thereby backed the compromise textreached by its legal affairs committee on 25 April 2023. This sets off the trilogue between representatives of the Parliament, the Council and the Commission.
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)).

Out Now: Dickinson, Natural Justice in Recognition and Enforcement of Foreign Judgments, Recueil des cours, Tome 446
Last summer, Andrew Dickinson (Professor of the Conflict of Laws, University of Oxford, and former editor of ConflictofLaws.net) delivered a special course at the summer course of the Hague Academy of International Law entitled ‘Natural Justice in Recognition and Enforcement of Foreign Judgments’. It has now been published as Volume 446 of the Recueil des cours / Collected Courses.
The blurb reads as follows:
This special course assesses the utility of ideas of ‘natural law’ and ‘natural justice’ as tools to explain, rationalise and develop the rules governing the recognition and enforcement of foreign judgments currently applied by the world’s legal orders.
After introducing the topic, the first part of the course consider how influential 17th and 18th century accounts of the law of nature sought to account for the relations existing between all human beings, as well as the creation of political societies with law-making powers, the global ordering of those societies and the role of adjudication as a means of resolving disputes within and among them. This provides the historical and intellectual background for what follows.
The principal part of the course considers how writers on the conflict of laws in this period drew upon and utilised these ideas, as the rules that we apply today to regulate foreign judgments began to take shape. This leads to a study of the further evolution of the legal landscape in the 19th century, highlighting the use of natural law reasoning by judges and commentators to explain and justify the effectiveness of individual exercises of adjudicatory authority beyond their original domains, as well as the later rejection of natural law thinking in favour of models centred on ideas of sovereignty and territoriality, which continue to dominate today.
Having completed this historical survey, the course examines the specific legacy of natural law reasoning in the common law world, involving the use of principles of ‘natural justice’ to deny recognition of unjust foreign judgments, as well as the counterparts of these principles in other legal systems and international treaties.
Drawing on the preceding material, the concluding chapter considers the case for renaturalising the law in this area, and the implications of following this path.
