On 12 December 2024, as a side event to the 84TH session of the General Assembly, UNIDROIT invited Legal Advisers from its Member States, CAHDI National Representatives, and Observers to attend the third edition of the series of High-Level Dialogues on Soft Law. This year’s edition focused on International Soft Law and Domestic Courts.
It was opened by UNIDROIT President Professor Maria Chiara Malaguti (Professor of International Law at the Faculty of Economics of the Università Cattolica del Sacro Cuore), Min. Plenipotentiary Stefano Zanini (Head of Service for Legal Affairs, Diplomatic Disputes & International Agreements, Ministry of Foreign Affairs and International Cooperation of Italy), and featured a panel that addressed references to international soft law by domestic courts in their assessment of domestic situations. Prof. Jessica Simor KC (Barrister at Matrix Chambers, UK, Visiting Professor London School of Economics and Goldsmiths Law), Prof. Jaehong Lee (Professor of Constitutional Law in Ewha Womans University, who connected from Seoul), and Prof. Carla Sieburgh (Professor of Private Law in particular the Effects of European Law on National Private Law, Radboud University Nijmegen, and member of UNIDROIT Governing Council), all presented their perspectives on the impact of International Soft Law such as the Paris agreement on domestic court cases, such as Shell Plc. in the Dutch courts (latest pronouncement: Dutch Court of Appeal, judgment 12 November 2024), Friends of the Earth v. UK Export Finance Department ( latest decision by the UK Supreme Court June 2023) and the Korean Constitutional Court decision of 29 August 2024.
The overall aim was to assess whether new trends could be detected in the way domestic courts approach international soft law, mindful of the fact that any parallelism must be examined in the light of the specificities of each domestic legal order, and whether these could be evidence of new forms of interaction between (international) soft law and (domestic) hard law. The ensuing debate led to many points of reflection which shall serve as an interesting stimulus for the next edition, planned in December 2025.
