This book provides the first comprehensive analysis of factors that transform a prima facie non-international armed conflict (NIAC) into an international armed conflict (IAC) and the consequences that follow from this process of internationalization. It examines in detail the historical development as well as the current state of the relevant rules of international humanitarian law. The discussion is grounded in general international law, complemented with abundant references to case law, and illustrated by examples from twentieth and twenty-first century armed conflicts. In Part I, the book puts forward a thorough catalogue of modalities of conflict internationalization that includes outside intervention, State dissolution, and recognition of belligerency. It then specifically considers the legal qualification of complex situations that feature more than two conflict parties and contrasts the mechanism of internationalization of armed conflicts with the reverse process of de-internationalization. Part II of the book challenges the conventional wisdom that members of non-State armed groups do not normally benefit from combatant status. It argues that the majority of fighters belonging to non-State armed groups in most types of internationalized armed conflicts are in fact eligible for combatant status. Finally, Part III turns to belligerent occupation, traditionally understood as a leading example of a notion that cannot be transposed to armed conflicts occurring in the territory of a single State. By contrast, the book argues in favour of the applicability of the law of belligerent occupation to internationalized armed conflicts.

This book comprises contributions by leading experts in the field of international humanitarian law on the subject of the categorisation or classification of armed conflict. It is divided into two sections: the first aims to provide the reader with a sound understanding of the legal questions surrounding the classification of hostilities and its consequences; the second includes ten case studies that examine practice in respect of classification. Understanding how classification operates in theory and practice is a precursor to identifying the relevant rules that govern parties to hostilities. With changing forms of armed conflict which may involve multi-national operations, transnational armed groups and organized criminal gangs, the need for clarity of the law is all-important. The case studies selected for analysis are Northern Ireland, DRC, Colombia, Afghanistan (from 2001), Gaza, South Ossetia, Iraq (from 2003), Lebanon (2006), the so-called war against Al-Qaeda, and future trends. The studies explore the legal consequences of classification particularly in respect of the use of force, detention in armed conflict, and the relationship between human rights law and international humanitarian law. The practice identified in the case studies allows the final chapter to draw conclusions as to the state of the law on classification.

"Due to their preponderance and intensity, non-international armed conflicts are currently very much in the public mind: often, more so than international armed conflicts. The present volume serves as a comprehensive introduction to the international legal regime of non-international armed conflicts, proceeding strictly in light of what the contemporary law is (as distinct from what the present author or anybody else would like it to be). Non-international armed conflicts raise a raft of issues that need to be addressed, including in particular their preconditions, thresholds, diverse forms and configurations; the discordant perspectives of the international and domestic legal systems; as well as the application of treaty and customary law to non-State actors. In addition, it is necessary to examine the consequences of intervention by foreign States; the role of the Security Council; the effects of recognition; State responsibility for wrongdoing to the installations, diplomats or nationals of foreign States, etc. The interface between the law of international and non-international armed conflicts is a matter of crucial concern. There are also numerous specific problems, ranging from the complexities of "failing States" to the recruitment and use of child-soldiers"--

The third edition of this work sets out a comprehensive and analytical manual of international humanitarian law, accompanied by case analysis and extensive explanatory commentary by a team of distinguished and internationally renowned experts.

Foreign investors often sustain injuries during international armed conflicts. This book sets out to explore how effective investment treaty protections really are. It designs an analytical framework that purports to explain and evaluate how effective and appropriate the application of the investment treaty regime is in times of armed conflict.

Customary International Humanitarian Law, Volume I: Rules is a comprehensive analysis of the customary rules of international humanitarian law applicable in international and non-international armed conflicts. In the absence of ratifications of important treaties in this area, this is clearly a publication of major importance, carried out at the express request of the international community. In so doing, this study identifies the common core of international humanitarian law binding on all parties to all armed conflicts. Comment Don:RWI.
