Pre-print article on SSRN on “Mirin” and the Future of Cross-Border Gender Recognition
I recently published the pre-print version of an article on SSRN that was accepted by the International Journal of Law, Policy and the Family. The article is called ““Mirin” and Beyond: Gender Identity and Private International Law in the EU“. The article is part of a special issue dealing with questions of gender identity that (probably) will come out at the beginning of 2026.
As it deals with matters of private international law (regarding gender identity) and the CJEU decision “Mirin”, I thought it might be interesting for the readers of this blog to get a short summary of the article. If it sparks your interest, of course, I would be glad if you consider reading the whole text – and to receive feedback and further thoughts on this topic. 🙂
Draft General Law on Private International Law aims to bring Brazil from the 19th into the 21st century
Guest post by Gustavo Ferraz de Campos Monaco, Full Professor of Private Internacional Law – University of São Paulo
In Brazilian law, the regulation of conflicts of laws is still based on a legislation from 1942, during a dictatorial regime, which explains its inspiration from the Italian fascist regime. The values prevailing in Brazilian society back then were quite different from those we hold today, especially in matters concerning family relationships. At that time, the family unit was viewed as having a single domicile, and questions related to the definition of parenthood were unthinkable outside traditional presumptions.
On at least two occasions over the past 83 years, attempts to draft new regulations were undertaken by leading figures in the field – Haroldo Valladão, Jacob Dolinger, and João Grandino Rodas – but both initiatives failed during the process, without the Plenary of the Legislative Houses having expressed an opinion on the merits of the projects.

Brazilian Supreme Court on the Hague Child Abduction Convention
Guest post by Janaína Albuquerque, International Family Lawyer; Research Associate at the NOVA Centre for the Study of Gender, Family and the Law; Legal Coordinator at Revibra Europa. Janaína represented Revibra, Instituto Maria da Penha and Instituto Superação da Violência Doméstica as amici curiae in the cases discussed below.
The Brazilian Supreme Court has recently delivered a landmark judgment in two Direct Actions of Unconstitutionality (Ações Diretas de Inconstitucionalidade, or ADIs), namely ADI 4245 and ADI 7686, concerning the application of the 1980 Hague Convention on the Civil Aspects of International Child Abduction(1980HC). Despite their denomination, these actions did not aim to invalidate the Convention, but rather to harmonize its interpretation with the principles enshrined in the Brazilian Federal Constitution.[1] Read more

Foreign Judgment Enforcement: Zimbabwean High Court holds that a Confirmed Mareva Injunction is a Final Judgment
In the Zimbabwe High Court decision of Ser and Another v Yong and Another (92 of 2026; HC/SUM 1957/2025) [2026] ZWHHC 137 (8 April 2026), the applicant obtained a freezing (Mareva) injunction from a foreign court in Singapore against assets linked to the respondents and then sought to have that order registered and enforced in Zimbabwe. The respondents resisted enforcement, arguing that the order should not be recognised because it was interlocutory in nature and because a relevant foreign defendant had not been joined to the original proceedings. The dispute therefore arose in the context of an attempt to extend the effect of a foreign asset-preservation order into Zimbabwe against parties and assets within its jurisdiction.
Virtual Workshop (in German) on May 5, 2026: Thomas Pfeiffer on „Anwaltliche Erfolgshonorare im Internationalen Privatrecht“
On Tuesday, May 5, 2026, the Hamburg Max Planck Institute will host its monthly virtual workshop Current Research in Private International Law at 11:00 a.m. – 12:30 p.m. (CEST).
Prof. Dr. Dr. h.c. Thomas Pfeiffer (Universität Heidelberg) will speak, in German, about the topic
“Anwaltliche Erfolgshonorare im Internationalen Privatrecht”
In Deutschland dürfte zum juristischen Allgemeinwissen zählen, dass anwaltliche Erfolgshonorare in den USA (und manchen anderen Rechtsordnungen) zulässig und vielfach sogar üblich sind, in Deutschland hingegen früher generell als unzulässig galten und auch heute noch deutlichen rechtlichen Grenzen unterliegen. Im IPR wird meist angenommen, dass sich diese Grenzen auch international zwingend durchsetzen, soweit es um deutsche Anwälte geht. Die schon früher relevante Frage nach Differenzierungen im Einzelnen hat durch die spürbaren Lockerungen der maßgebenden sachrechtlichen Regeln in jüngerer Zeit nochmals an Bedeutung gewonnen.
The presentation will be followed by open discussion. All are welcome. More information and sign-up here.
