"This book aims to make the three contributions mentioned above by responding to the following key question: can the concepts of necessity in WTO law and CIL influence each other to achieve a more coherent concept of necessity across different fields of international law? The main reasons for focusing on these two concepts of necessity in this book are: (a) the clarity of their respective definitions; (b) their extensive application in the respective fields of international law where they operate; and (c) their potential to influence the development of the concept of necessity in other fields of international law. Since the gist of this book is to finally discuss the concept of necessity in the broader context of fragmentation and coherence of international law, it is requisite to analyze in detail the relationship between these two relatively elucidated concepts of necessity in international law. Analysis of this relationship must culminate in identifying the possibility for these two differing concepts of necessity to learn from (i.e., influence) each other so that a more coherent concept of necessity can develop in international law"-
