The International Obligation of the Uniform and Autonomous Interpretation of Private Law Conventions: Consequences for Domestic Courts and International Organisations

Abstract

This article addresses the issue of the uniform and autonomous interpretation of private law conventions, including of private international law conventions, from the perspective of their Contracting States, particularly their judiciaries, and of the international organizations. Firstly, the author analyses the use of standard uniform interpretation clauses, and the origin of such clauses, in the context of the Hague Conference on Private International Law. The following part the article addresses negative and positive obligations imposed on States and their judiciaries under international law regarding the uniform and autonomous interpretation of international treaties. It is argued that States are not only obliged to refrain from referring to concepts from national laws for the purpose of the interpretation of international law instruments, but also that they face certain positive obligations in the process of applying the conventions. Those include referring to foreign case law, international scholarship, and under certain circumstances, also to travaux preparatoires. Thirdly, the author discusses the role of international organizations—e.g. HCCH, UNCITRAL, UNIDROIT, in safeguarding and facilitating the uniform and autonomous interpretation of private law conventions. It does so by describing various related tools and approaches, with examples and comments on their practical use (e.g. advisory opinions, information sharing, access to supplementary material, judicial exchanges and legislative action).
