International high-tech surrogacy and legal developments in the Netherlands
This blogpost is an edited version of this blogpost written in Dutch by Stichting IJI (The Hague Institute for private international law and foreign law). We thought it was interesting to also bring it to the attention of the international readership of this blog.
Introduction
In the Netherlands, international high-tech surrogacy is a hot topic, resulting in interesting legal developments. Recently, a Dutch District Court dealt with a case on the recognition of US court decisions on legal parenthood over children born from a high-tech surrogacy trajectory in the US, providing many private international law insights on how to assess such request for recognition. Furthermore, on July 4 a bill was proposed that encloses several private international law provisions. This blogpost briefly highlights both developments.
Same-sex relationships concluded abroad in Namibia – Between (Limited) Judicial Recognition and Legislative Rejection
There is no doubt that the issue of same-sex marriage is highly controversial. This is true for both liberal and conservative societies, especially when the same-sex union to be formed involves parties from different countries. Liberal societies may be tempted to open up access to same-sex marriage to all, especially when their citizens are involved and regardless of whether the same-sex marriage is permitted under the personal law of the other foreign party. For conservative societies, the challenge is even greater, as local authorities may have to decide whether or not to recognise same-sex marriages contracted abroad (in particular when their nationals are involved). The issue becomes even more complicated in countries where domestic law is hostile to, or even criminalises, same-sex relationships.
Cassirer on Remand: Considering the Laws of Other Interested States
This post is by Carlos Manuel Vázquez, a professor of law at Georgetown Law School. It is cross-posted at Transnational Litigation Blog.
Claude Cassirer brought suit in federal court in California eighteen years ago against the Thyssen Bornemisza Museum of Madrid, Spain, to recover a painting by Camille Pissarro that was stolen from his grandmother by the Nazis during World War II. After a reversal and remand from the U.S. Supreme Court last summer, the case is now before the Ninth Circuit for decision of the legal question that is likely to be decisive: which law governs?
The district court and the court of appeals have so far framed the issue as a binary choice: the governing law on the merits is either that of Spain or that of California. I suggest here that the issue is better framed as a choice between the law of Spain, on the one hand, and the laws of all the other states or countries with connections to the dispute, on the other. (Disclosure: I submitted expert declarations in support of the plaintiffs on issues of public international law during earlier phases of this case.)
The U.S. Court of Appeals for the Ninth Circuit has affirmed the district court’s holding that, under the law of Spain, the plaintiff loses because the museum acquired title to the painting through adverse possession (otherwise known as acquisitive prescription). It is equally clear that, under the law of California, the plaintiff would prevail because California does not recognize the acquisition of title to moveable property through adverse possession. What has so far not featured prominently in the courts’ analyses of the choice-of-law issue is that the plaintiff would also prevail under the laws of all the other jurisdictions that have relevant connections to the dispute. Under governmental interest analysis, this should be central to the analysis. Read more

The Establishment of the International Organization for Mediation (IOMed)
On 30 May 2025, the signing of the Convention on the Establishment of the International Organization for Mediation (IOMed) in Hong Kong marked an advancement in the field of international dispute resolution. Attended by representatives from over 85 countries and 20 international organisations – including the United Nations – the event introduced a treaty-based institutional framework dedicated specifically to mediation.
The IOMed Convention – with equally authentic texts in Arabic, Chinese, English, French, Russian, and Spanish – outlines a structured, treaty-based model of mediation whose scope is deliberately broad, encompassing disputes between States, between a State and nationals of other States, as well as disputes between private parties involved in international commercial relationships (Article 24).
A defining feature of the IOMed Convention is its treatment of the legal effect and enforceability of mediated outcomes. Articles 40 and 41 affirm both the binding nature of settlement agreements resulting from IOMed-facilitated mediation and their enforceability within the domestic legal systems of contracting States. This model of consensual yet normatively binding dispute resolution finds a compelling parallel in – and complements – the United Nations Convention on International Settlement Agreements Resulting from Mediation (the Singapore Convention). The Singapore Convention – which, as of 3 July 2025, counts 58 signatories and 18 parties – reinforces party autonomy while requiring the good faith implementation of mediated settlements. Particularly significant is Article 3 of the Convention, which obliges courts in contracting States to recognise international commercial settlement agreements and to enforce them in accordance with domestic procedures, provided the agreement satisfies the Convention’s requirements. While the Singapore Convention offers a uniform and efficient framework for the enforcement and “invocation” (see Art. 3(2)) of international settlement agreements resulting from mediation, the IOMed Convention contributes by establishing the institutional and procedural framework necessary for the conduct of mediation itself. Together, these instruments enhance both the normative foundation and the practical viability of cross-border mediation, thereby reinforcing its legitimacy in complex international commercial contexts.
Beyond its dispute resolution functions, IOMed also assumes a broader mandate to promote mediation (Art. 5). This includes fostering best practices (Art. 5(b)), organising conferences and training initiatives (Art. 5(c)), and implementing targeted capacity-building programmes (Art. 5(d)). A dedicated Mediation Fund (Art. 44), financed through voluntary contributions, is intended to promote equitable access to services, while a Capacity Building Committee (Art. 43) provides strategic oversight in this domain.
Ultimately, the IOMed Convention does not seek to alter the fundamental character of mediation. Rather, it aims to provide a coherent legal and institutional foundation at the international level. By anchoring mediation within a treaty-based framework, the IOMed Convention offers States and other actors a structured yet flexible environment in which to pursue dialogue-based resolution, with greater predictability, neutrality, and institutional support – while preserving the essential consensual nature that distinguishes mediation from adjudication. While its practical impact will depend on how States and other actors engage with its mechanisms over time, the Convention offers a new platform for exploring the potential of mediation in a variety of international contexts.
