Because of its unique nature, the sources of international law are not always easy to identify and interpret. This book provides an ideal introduction to these sources for anyone needing to better understand where international law comes from. As well as looking at treaties and custom, the book will look at more modern and controversial sources.

This work explores in depth the legal consequences of peremptory norms.

One of the most complex doctrines in contemporary international law, jus cogens is the immediate product of the socialization of the international community following the Second World War. However, the doctrine resonates in a centuries-old legal tradition which constrains the dynamics of voluntarism that characterize conventional international law. To reconcile this modern iteration of individual-oriented public order norms with the traditionally state-based form of international law, Thomas Weatherall applies the idea of a social contract to structure the analysis of jus cogens into four areas: authority, sources, content and enforcement. The legal and political implications of this analysis give form to jus cogens as the product of interrelation across an individual-oriented normative framework, a state-based legal order, and values common to the international community as a whole.
