Overview
Summary
International law is often perceived as the product of treaties and court decisions, yet few publications explain how those legal instruments actually come into existence. Drawing on first-hand experience within the United Nations, this Practical Insider’s Guide takes readers behind the scenes of international law-making, exploring the complementary roles of the UN International Law Commission and the UN General Assembly’s Sixth Committee. Through practical examples, institutional insights, and the case study of the draft articles on crimes against humanity, the Guide illustrates how legal expertise and political negotiation interact to shape the international legal order. It is written for diplomats, lawyers, students, academics, and anyone seeking a practical understanding of one of the least explained processes within the United Nations.
Key points
- The United Nations develops international law through a dynamic institutional process involving multiple organs, not through treaty negotiations alone.
- The International Law Commission serves as the United Nations’ principal expert body responsible for the progressive development and codification of international law.
- The Sixth Committee provides the political forum where Member States determine whether legal proposals should evolve into multilateral treaties.
- The relationship between the International Law Commission and the Sixth Committee is complementary: one contributes legal expertise, the other political legitimacy.
- Political negotiation may delay the adoption of international conventions, but it rarely diminishes the long-term normative influence of the International Law Commission’s work.
- Some of the world’s most influential treaties - including the Vienna Convention on Diplomatic Relations and the Vienna Convention on the Law of Treaties - originated from the work of the International Law Commission.
- Strengthening dialogue between the International Law Commission and the Sixth Committee would contribute to a more effective and responsive international law-making process.
