Author Description

The question of the sources of international law inevitably raises some well-known scholarly controversies: where do the rules of international law come from? Through which processes are they made? How are they ascertained? Where does the international legal order begin and end? These traditional questions bear on at least two different levels of understanding. First, how are international norms validated as rules of international 'law', i.e. legally binding norms? This is the static question of the pedigree of international legal rules and the boundaries of the international legal order. Secondly, what are the processes through which these rules are made? This is the dynamic question of the making of these rules and of the exercise of public authority in international law. This book explores the various facets of the sources of international law. It provides a systematic overview of the key issues and debates around the sources of international law, including recent contestations thereof. It also offers an authoritative theoretical guide for anyone studying or working within but also outside international law wishing to understand one of its most fundamental questions.
