Explores how international law deals with detention conducted by non-State armed groups and the motivations behind these practices.

The proliferation of non-state armed groups and non-international armed conflicts since the end of the Second World War has challenged the legal frameworks which govern conduct in armed conflict. While aspects of international humanitarian law apply to such conflicts, international law can only go part of the way to explaining behaviour by armed groups. This book seeks to refocus discussion on the limits to armed conflict in such settings by examining the norms that underpin international humanitarian law as espoused by these armed groups to give a clearer picture as to the collectively constructed appropriateness of certain behaviours in or limits to warfare. The specific research question is “What are the norms of armed conflict as identified by non-state armed groups?” Using Winston’s norm cluster model, this study seeks to examine and map the ideations and behavioural prescriptions that constitute the armed conflict norm cluster as defined by non-state armed groups. To do this, it utilises a qualitative content analysis of documents from non-state armed groups coded to identify the different elements of this norm cluster as well as the frequency, pervasiveness, and connections between these elements. The findings showed that, while international humanitarian law is universal, these norms limiting armed conflict are not, with no norm being seen across all contexts examined. Core norms of international humanitarian law, especially those supported by norm entrepreneurs, were seen to be the focus of sub-clusters and the emergence of new parts of the norm cluster could be observed over time. The findings suggest that further work with the conceptualisation of limits to armed conflict as norms could be useful in improving the embeddedness of norms amongst non-state armed groups and could be useful in reconceptualising limits to armed conflict in cases where broadly accepted norms face growing contestation.

The number of armed conflicts featuring extreme violence against the civilian population in areas with no or little state authority has risen significantly since the early 1990s. This phenomenon has been particularly prevalent in the African Great Lakes Region. This collection of essays evaluates, from an interdisciplinary perspective, the various traditional and alternative instruments for inducing compliance with international humanitarian law. In particular, it explores the potential of persuasion, as well as hierarchical means such as criminal justice on the international and domestic level or quasi-judicial mechanisms by armed groups. Furthermore, it evaluates the role and potential of human rights bodies, peacekeeping missions and the UN Security Council's special compliance system for children and armed conflicts. It also considers how Common Article 1 to the Geneva Conventions and the law of state responsibility could both potentially increase compliance with international humanitarian law.

This is a comprehensive Report on every armed conflict which took place during 2012. It is the first of a new series of annual reports on armed conflicts across the globe, offering an unprecedented overview of the nature, range, and impact of these conflicts and the legal issues they create. In Part I the Report describes its criteria for the identification and classification of armed conflicts under international law, and the legal consequences that flow from this classification. It sets out a list of armed conflicts in 2012, categorising each as international, non-international, or a military occupation, with estimates of civilian and military casualties. In Part II, each of these conflicts are examined in more detail, with an overview of the belligerents, means and methods of warfare, the applicable treaties and rules, and any prosecutions for, investigations into, or robust allegations of war crimes. Part III of the Report provides detailed thematic analysis of key legal developments which arose in the context of these conflicts, allowing for a more in-depth reflection on cross-cutting questions and controversies. The topics under investigation in this Report include drone strikes, the use of explosive weapons, small arms, forced displacement of civilians, detention at Guantanamo Bay, and the enforcement of international humanitarian and criminal law in both national and international courts. The Report gives a full and accessible overview of armed conflicts in 2012. It should be the first port of call for everyone working in the field.

This important and unique volume begins with seven essays that discuss the contemporary challenges to implementing international humanitarian law. Its second and largest section comprises 263 entries covering the vast majority of IHL concepts. Written by a wide range of experts, each entry explains the essential legal parameters of a particular element of IHL, while offering practical examples and, where relevant, historical considerations, and supplying a short bibliography for further research. The starting point for the selection were notions arising from the Geneva Conventions, the Additional Protocols, and other IHL treaties. However, the reader will also encounter entries going beyond the typical scope of IHL, such as those related to the protection of the natural environment and animals, and entries that, in addition to an IHL perspective, discuss relevant issues through the lens of human rights law, refugee law, international criminal law, the law on State responsibility, national law, and so on. The editors have also attempted to take into account certain concepts that have no direct foundation in IHL, but that are commonly used in mass media and politics, or generate wide interest in contemporary society, such as drones, economic warfare, cyber warfare, sniping, targeted killings, transitional justice, terrorism, and many other topics. The Companion to International Humanitarian Law offers a much-needed tool for both scholars and practitioners, supplying information accessible enough to enable a variety of users to quickly familiarise themselves with it and sufficiently comprehensive to be a source for reflection and further research for more demanding users. Its aim is to facilitate the practical application of IHL, and be of use to a wide audience interested in or confronted with IHL, ranging from professionals in humanitarian assistance and protection in the field, legal officers and advisers at the national and international level, trainers, academics, scholars, and students.
