Every State has an obligation to prevent terrorist attacks emanating from its territory. This proposition stems from various multilateral agreements and UN Security Council resolutions. This study exhaustively addresses the scope of this obligation of prevention and the legal consequences flowing from its violation, so as to provide greater clarity on governments' counterterrorism duties and to enhance State accountability for preventable wrongs. It defines the contents and contours of the obligation while placing critical emphasis on the mechanics of State responsibility. Whether obscured by new technologies like the Internet, the sophisticated cellular structure of some terrorist organisations or convoluted political realities, the level of governmental involvement in terrorist activities is no longer readily discernible in every instance. Furthermore, the prospect of governments waging surrogate warfare through proxies also poses intractable challenges to the mechanism of attribution in the context of State responsibility. This monograph sets out the shortcomings of the extant scheme of State responsibility while identifying a paradigm shift towards more indirect modes of accountability under international law, a trend corroborated by recent State and institutional practice. Drawing on varied legal and theoretical influences, the study devises and prescriptively argues for the implementation of a strict liability-inspired model grounded in the logic of indirect responsibility with a view to enhancing State compliance with counterterrorism obligations. This shifts the policy focus squarely to prevention, while promoting multilateralism and transnational cooperation. Ultimately, the legal and policy sensibilities underlying the book converge into a new theory of prevention in counterterrorism contexts. From the Foreword by Judge Bruno Simma, International Court of Justice "Even if one might disagree with the bases on which the author constructs his argument, the execution of the argument is solid and thorough. The coverage of the major policy arguments and the available legal source materials is equally impressive. Moreover, the author's positions are genuinely progressive and present a fairly innovative solution, in the form of a strict liability mechanism...It behoves all scholars and practitioners of international law with an interest in combating international terrorism to consider the proposals outlined in this book." Transnational Terrorism and State Accountability by Vincent-Joël Proulx has been awarded the 2014 Myres McDougal Prize for best book in Law, Science, and Policy from the Society of Policy Scientists.

The book analyzes State responsibility in international law from a holistic and critical perspective.

This is the fiftieth volume of The Canadian Yearbook of International Law. The contents of this special anniversary edition reflect the diversity of Canadian and international thought, opinion, and practice on current problems of international law. Included are a retrospective examination of Canadian approaches and contributions to international law during the Yearbook's first fifty years as well as cutting-edge analyses and commentary on a wide range of issues, such as the use of battlefield biometrics, the cultural dimensions of sustainable development, Omar Khadr's combatancy and child-soldier status, and immunities for gross violations of international human rights.

This book examines the responsibility of States and international organizations for complicity (aid or assistance) in an internationally wrongful act. Despite the recognition of responsibility for complicity as a rule of customary international law by the International Court of Justice, this book argues that the effectiveness and utility of this form of responsibility is fraught with systemic and operational limits. These limits include a lack of clarity in its constituent elements, its co-existence with primary rules prohibiting complicity and the obligations of due diligence, its implementation and the underlying causal tests, its uncertain relationship to other forms of shared and indirect responsibility, and its potential as a form of attribution of conduct. This book submits that the content and elements of this form of responsibility need adjustments to respond more effectively to the phenomenon of complicity in international affairs.

Since the 9/11 attacks, international organizations have become actively engaged in devising counterterrorism strategies and frameworks. This monograph examines the role UN organs can play in implementing the law of State responsibility in global security contexts, using transnational terrorism as its principal case study. The institutional mechanisms utilized by the UN in implementing State responsibility are assessed in detail, shedding light on how the ICJ, the General Assembly and the Security Council contribute to the implementation of State responsibility in the context of global security. By acknowledging the Security Council's role as a post-9/11 legislator, this book argues that the Council can play an important and sometimes determinant role in implementing a State's legal responsibility for failing to prevent terrorism, both inside and outside the Chapter VII framework. Featuring a discussion of the more controversial consequences flowing from State responsibility, this monograph also explores the prospect of injured States adopting forcible measures against responsible States for their failures to prevent terrorism. The book investigates whether self-defence and other forcible reactions, envisaged both inside and outside the Council, can be reconciled with State responsibility principles.

Attacks by network-based transnational terrorist groups cause on average 25,000 deaths every year worldwide, with the law enforcement agencies of some states facing many challenges in bringing those responsible to justice. Despite various attempts to codify the law on transnational terrorism since the 1930s, a crime of transnational terrorism under international law remains contested, reflecting concerns regarding the relative importance of prosecuting members of transnational terrorist groups before the International Criminal Court. This book critically examines the limits of international criminal law in bringing members of transnational terrorist groups to justice in the context of changing methods of warfare, drawing from human rights, sociology, and best practices in international criminal justice. Drawing on organisational network theory, Anna Marie Brennan explores the nature of international crimes and assesses the potential for the International Criminal Court to prosecute and investigate alleged crimes perpetrated by members of transnational terrorist groups, paying particular attention to their modus operandi and organisational structure. This book argues that because of the network-based organisational structure of some transnational terrorist groups, achieving justice for victims will prove challenging, in the context of the relationship between the commanders and the subordinate members of the group requiring a re-evaluation of accountability mechanisms at the international level. In advancing an innovative perspective on the accountability of members of transnational terrorist groups, and in offering solutions to current challenges, the book will be of great interest and use to academic, practitioners, and students engaged in the study of terrorism, the ICC, or international humanitarian law.

This newly revised and updated second edition provides a comprehensive overview of international counter-terrorism law and practice. Brand new and revised chapters provide critical commentary on the law from leading scholars and practitioners in the field, including new topics for this edition such as foreign terrorist fighters, the nexus between organized crime and terrorism, and the prevention of violent extremism.

In this cutting-edge book, Alexander Orakhelashvili addresses the doctrine of causation, examining its suitability to influence, or contribute to, the process of responsibility of State and non-State actors in international law. In doing so, the book considers the record so far and places the international legal system’s practical experience within its normative context.

This timely book discusses the problem of State responsibility in connection with terrorist acts committed by non-State actors. It provides a detailed assessment of the consequences of wrongful acts of the State using contemporary examples such as the Bosnian Genocide, 9/11, and the 2016 and 2020 Nice attacks.

Sovereignty in the Age of Global Terrorism: The Role of International Organisations analyses the role of international organisations in adopting counterterrorism measures after 9/11 and the impact of these measures on the sovereignty of their Member States. The book examines the counterterrorism regimes of the UN and four regional organisations (with a special focus on the EU), as well as their implementation by their Member States. It includes the 2008 Kadi case of the European Court of Justice as case study of the conflicts between legal regimes that have competing mandates to fight terrorism. The relevance of the book lies in both comprehending the rationale for international actions against terrorism and the consequences on international law and State sovereignty.
