“Squaring the Circle – Recognising Rare Family Forms and Gender Identities Within the EU”

The principle of recognition has long been a feature of European private international law – increasingly also in matters of family law and the law of personal status. Recent case law has focused on so-called rainbow families – same-sex marriages and parenthood – and changes in legal gender markers. These are issues that are treated very differently across the EU, with extensive protection and equal treatment in some Member States, and clear and in some cases constitutional rejection in others. The CJEU is therefore trying to reconcile two contradictory principles: The exclusive competence of Member States in substantive family and civil status law on the one hand and the Union-wide recognition of families and gender identities registered in one Member State on the other. This presentation will examine how the CJEU attempts to resolve this conflict and what conclusions can be drawn from the case law on the nature and scope of the principle of recognition.

The presentation will be followed by open discussion. All are welcome. More information and sign-up here.

“EU Private International Law at a Time of ‘Broken Multilateralism’ and Growing Geo-Political Tensions”

Multilateralism is in crisis. The role of world organisations in international politics and law-making is increasingly being questioned, as some key actors in the global arena no longer consider cooperation and collective action the best way to address common concerns. While multilateralism is not obsolete, let alone ‘dead’, as some claim, there is a growing consensus that current governance schemes need profound reconsideration. The EU, multilateralism’s staunchest defender, is especially exposed to these developments. While the evolution of multilateralism is set to affect all areas of international cooperation, each field has, arguably, its specificities. What features does cooperation in the field of private international law display in this regard? How can the crisis of multilateralism influence the way in which the EU deals with judicial cooperation, be it through its legislation, in the relations with its neighbours and at the global level? What structural changes are under way in global fora, such as the HCCH, and what is their impact on the EU’s own agenda and methods of work?
