International Military Missions And International Law

By considering different international legal sources, including humanitarian law, human rights and criminal law, this book seeks to identify the rules applicable to International Military Missions engaged in different actions in the context of peace operations.

Based on best-practice rules of global importance, this handbook offers authoritative commentary and analysis of the international law of military operations, encompassing self-defence, peace operations, and other uses of force.

The 'Legal Pluriverse' Surrounding Multinational Military Operations conceptualizes and examines the "Pluriverse": the multiplicity of rules that apply to and regulate contemporary multinational missions, and the array of actors involved. These operations are further complicated by changes to the classification of the conflict, and the asymmetry of obligations on participants. Structured into five parts, this work seeks, through the diversity of its authorship, to set out the web of legal regimes applicable to military operations including forces from more than one state. It maps out the ways in which different regimes interact, beginning with the laws of armed conflict and their relation to international humanitarian and human rights norms, and extending through to areas like law of the sea and environmental law. A variety of contributors systematically compile and take stock of the various legal regimes that make up the pluriverse, assessing how these rules interact, exposing norm conflicts, areas of legal uncertainty, or protective loopholes. In this way, they identify and evaluate approaches to better streamline the different applicable legal frameworks with a view to enhancing cooperation and thereby ensuring the long-term success of multinational military operations.

In this work, a distinguished group of military experts analyze how the law applies, and is applied, during military operations on and off the battlefield. The editors focus on how the law is operationalized, or actually implemented, in a wide swath of military activities.

The book systematically analyses the relationship and interaction between rules of engagement (ROE) and the legal framework regulating armed conflicts, both at the international and national levels. At the international level, the relationship between ROE and human rights law and international humanitarian law is explored. At the national level, the book relates ROE to (comparative) criminal law. A separate chapter analyses the complex relationship between self-defence law and rules of engagement. It is the first monograph to comprehensively examine these issues and to analyse how ROE interact with the various sources of the (international) law of military operations, both in terms of the law as a source for these rules and how the law is reflected and implemented through them. In doing so, and based on the author's own experience, the book provides examples of how complicated, often controversial issues of law can be resolved while keeping the rules understandable at all levels of military operations. Aimed at both scholars and practitioners, the book provides a bridge between the academic world and the operational world. It provides new insights for both of those audiences in terms of understanding how the law applies to - and through - the rules on the use of force for military operations.

This book is a tribute to the work of Professor Terry Gill, offered to him by friends and colleagues who are also academics and/or practitioners in the field of International Law of Military Operations (ILMO). ILMO is a distinct sub-discipline within public international law and domestic public law, covering all domains of military operations: land, sea, air and (cyber)space. As such, ILMO includes elements of other branches of public international law, such as international humanitarian law, human rights law, the law on the use of force, the law of the sea, the law of State responsibility, arms control law and the law of international organisations. Importantly, as a hybrid field of law, ILMO covers the legal basis for military deployment both nationally and internationally, as well as the subsequent international legal regimes applicable to the forces (once deployed) and the domestic administrative and constitutional issues related to the relevant forces. Control is a central notion of ILMO and is the leading theme of this book. The contributions in this book reflect the variety of legal frameworks applicable to military operations and offer an insightful view into the various legal and factual roles of control. The legal notion of control is considered, inter alia, in relation to restraints in the decision to deploy military forces and the legal basis for doing so. The impact of control is also discussed in relation to State and command responsibility and in different situations, including during peace operations, occupation and other situations of armed conflict. Additionally, control is considered over the armed forces themselves, over detainees migrants at sea and over the type or scale of force used in military operations, through targeting rules or rules of engagement. Furthermore, the book contains several discussions of control in the case law of international courts, within arms control law, weapons law and in the context of autonomous weapons systems. The editors of the book are all practitioners, academically affiliated to the Faculty of Military Sciences (War Studies) of the Netherlands Defence Academy and/or the Law Faculty of the University of Amsterdam.
