Joint ELI-UNIDROIT event in Paris celebrates the UNIDROIT Centenary European Regional Conference and the 15th ELI Anniversary

On 1 September 2026, in Paris, the European Law Institute (ELI) and the International Institute for the Unification of Private Law (UNIDROIT) came together to celebrate two significant milestones: the UNIDROIT’s Centenary and the ELI 15 th Anniversary.

The joint event, hosted by the Université Paris II Panthéon Assas and the Société de Législation Comparée,  provided an opportunity to reflect on the achievements of both UNIDROIT and ELI, their longstanding cooperation and the challenges that will shape the future development of law. Bringing together leading voices from the judiciary, academia, international organisations and law reform bodies, the discussions highlighted the continuing importance of international legal collaboration in developing coherent, resilient and future-oriented legal frameworks.

The Programme opened with remarks by Stéphane Braconnier (President of University Paris-Panthéon-Assas); François Molinié (President of the French Society of Comparative Law (Société de législation comparée)); Teresa Rodríguez de las Heras Ballell (ELI President); and Ignacio Tirado (Secretary General of UNIDROIT).

A keynote speech on “Financial stability in Europe” was then delivered by Fernando Restoy, Chair of the Financial Stability Institute,  moderated by Sylvaine Poillot Peruzzetto (Member of the ELI Executive Committee and Counsellor at the French Court of Cassation).

Across three substantive panels, participants explored the interplay between global and regional harmonisation in private law (Ignacio Tirado, Hon Judge Diane Wood, Director of the American Law Institute (ALI); Jean-François Riffard, Dean of Université Clermont-Ferrand; Lord John Thomas, President of the Quatar International Court and Member of the House of Lords, chaired by Marko Bošnjak, Judge of the EU Court of Justice); the role of soft law in the harmonisation of contract law (Anna Veneziano, Deputy Secretary-General, UNIDROIT; Myrte Thijssen, UNIDROIT Senior Legal Officer; Pascal Pichonnaz, Professor at Fribourg University and former ELI President; Hugh Beale, Emeritus, University of Warwick, moderated by Pietro Sirena, Eli Vice-President and Dean of the Bocconi Law School in Milan);  emerging challenges for legal harmonisation in the fields of new technologies and sustainability (Matthias Lehmann, University of Vienna; Louise Gullifer,Rouse Ball Professor of English Law, University of Cambridge and Chair of the Law Faculty Board; Philipp Paech (Professor at the London School of Economics); Teresa Rodriguez de las Heras Ballell, chaired by Sir Geoffrey Vos, ELI Vice-President, Master of the Rolls and Head of Civil Justice in England and Wales).

 

 

 

 

 

The final session of the conference was dedicated to the discussion of the draft UNIDROIT Centenary White Paper on Civil Procedure and Dispute Resolution, prepared by the Committee of the Workstream on Procedural Law and Dispute Resolution (including Hon Diane Wood as Chair and Rolf Stuerner, Emeritus, University of Freiburg; John Sorabji; Professor at University College London; Teresa Rodriguez de las Heras Ballell; Etsuko Sugiyama, Professor at Hitotsubashi University in Japan; Maria Cecilia Fresnedo de Aguirre, Professor at Universidad de la Republica Uruguay. The draft White Paper reviews UNIDROIT’s contributions in this field and identifies potential directions for future projects as part of the core scientific programme of UNIDROIT’s Centenary programme in this thematic area. Panels were followed by a lively discussion with the audience.

As part of the celebrations marking 100 years of UNIDROIT, the Institute is organising a series of regional conferences around the world to reflect on the role of international legal harmonisation and on the continuing contribution of UNIDROIT ‘s instruments to the development of private law in each region and beyond. The Unidroit Centenary Regional Conferences bring together academics, judges, practitioners, policymakers, representatives of international organisations, and other public and private stakeholders to discuss the relevance, implementation, and future development of UNIDROIT’s work in the context of the legal traditions and priorities of the respective regions.
