In this episode of EJIL: Live! the Editor-in-Chief of the Journal, Professor Joseph Weiler, speaks with Professor Liam Murphy of New York University, whose article, “Law beyond the State: Some Philosophical Questions”, appears as the central piece in an EJIL: Debate! in Volume 28, Issue 1.
A legal philosopher, Professor Murphy takes up the challenge of exploring the realm of international law, an area largely ignored by Anglo-American legal philosophers since H.L.A Hart. Professor Murphy seeks to offer new perspectives on the famous chapter 10 of Hart’s The Concept of Law, and to critique the understanding of the international legal system set out therein. This then serves as the framework for his discussion of two core issues: the relevant grounds of law in international law – what factors are relevant in determining the content of law in force – and what makes international law a legal order. Professor Murphy also reflects on the Replies to his article, published in the same issue of the Journal, and how these prompted him to give further thought to the issues addressed in his article.
