Private military organizations are a new and important feature of the international landscape. They offer control of potential massive violence to the highest bidder with very limited accountability. This book offers critical insights into both the phenomenon and the challenges of and potential for regulation.

This work examines the ability of existing and evolving PMC regulation to adequately control private force, and it challenges the capacity of international law to deliver accountability in the event of private military company (PMC) misconduct. From medieval to early modern history, private soldiers dominated the military realm and were fundamental to the waging of wars until the rise of a national citizen army. Today, PMCs are again a significant force, performing various security, logistics, and strategy functions across the world. Unlike mercenaries or any other form of irregular force, PMCs acquired a corporate legal personality, a legitimising status that alters the governance model of today. Drawing on historical examples of different forms of governance, the relationship between neoliberal states and private military companies is conceptualised here as a form of a ‘shared governance'. It reflects states’ reliance on PMCs relinquishing a degree of their power and transferring certain functions to the private sector. As non-state actors grow in authority, wielding power, and making claims to legitimacy through self-regulation, other sources of law also become imaginable and relevant to enact regulation and invoke responsibility.

The past two decades have witnessed the rapid proliferation of private military and security companies (PMSCs) in armed conflicts around the world, with PMSCs participating in, for example, offensive combat, prisoner interrogation and the provision of advice and training. The extensive outsourcing of military and security activities has challenged conventional conceptions of the state as the primary holder of coercive power and raised concerns about the reduction in state control over the use of violence. Hannah Tonkin critically analyses the international obligations on three key states - the hiring state, the home state and the host state of a PMSC - and identifies the circumstances in which PMSC misconduct may give rise to state responsibility. This analysis will facilitate the assessment of state responsibility in cases of PMSC misconduct and set standards to guide states in developing their domestic laws and policies on private security.

"This book's primary concern is the application of international humanitarian law and international human rights law in addressing the business conduct of private military and security companies (PMSCs) during armed conflicts, as well as state responsibility for human rights violations and current attempts at international regulation. The book discusses four interconnected themes. First, it differentiates private contractors from mercenaries, presenting an historical overview of private violence. Second, it situates PMSCs' employees under the legal status of civilian or combatant in accordance with the Third and Fourth Geneva Conventions of 1949. It then investigates the existing law on state responsibility and what sort of responsibility companies and their employees can face. Finally, the book explores current developments on regulation within the industry, on national, regional and international levels. These themes are connected by the argument that, in order to find gaps in the existing laws, it is necessary to establish what they are, what law is applicable and what further developments are needed"--Book jacket.

In Private Military and Security Contractors (PMSCs) a multinational team of scholars and experts address a developing phenomenon: controlling the use of privatized force by states in international politics. Robust analyses of the evolving, multi-layered tapestry of formal and informal mechanisms of control address the microfoundations of the market, such as the social and role identities of contract employees, their acceptance by military personnel, and potential tensions between them. The extent and willingness of key states—South Africa, the United States, Canada, the United Kingdom, and Israel—to monitor and enforce discipline to structure their contractual relations with PMSCs on land and at sea is examined, as is the ability of the industry to regulate itself. Also discussed is the nascent international legal regime to reinforce state and industry efforts to encourage effective practices, punish inappropriate behavior, and shape the market to minimize the hazards of loosening states’ oligopolistic control over the means of legitimate organized violence. The volume presents a theoretically-informed synthesis of micro- and macro-levels of analysis, offering new insights into the challenges of controlling the agents of organized violence used by states for scholars and practitioners alike.

Many states view Private Military and Security Companies (PMSCs) as crucial to implementing their security policy. However, reoccurring incidents of human rights violations have led the international community, private sector, and civil society to acknowledge the need for more control over the use of PMSCs. Growing state support for The Montreux Document and an ever growing number of signatory companies to the International Code of Conduct for Security Providers (ICoC) show that self-regulation through non-binding norms has shifted to the center of the debate. This book examines the promises and dangers of emerging non-binding PMSC regulation alongside more traditional forms of law-making, such as plans for an international convention on the use of PMSCs. It offers an in-depth analysis of legal and political developments that led to the proliferation of The Montreux Document and the ICoC. Identifying the state side of duties and corporate responsibility as leaving gaps and grey zones in international law, the book analyzes how both instruments address 'the responsibility to protect' and 'the responsibility to respect.' Covering the Private Security Providers' Association's Articles of Association, the most recent developments on the establishment of a PMSC oversight mechanism are included. Finally, the book provides an original theory of how both instruments could become more effective to protect victims against PMSC human rights violations: The Montreux Document, by developing into a form of customary international law, and the standards of the ICoC framework, by developing into more binding normative standards as a form of 'corporate custom.'

A growing number of states use private military and security companies (PMSCs) for a variety of tasks, which were traditionally fulfilled by soldiers. This book provides a comprehensive analysis of the law that applies to PMSCs active in situations of armed conflict, focusing on international humanitarian law. It examines the limits in international law on how states may use private actors, taking the debate beyond the question of whether PMSCs are mercenaries. The authors delve into issues such as how PMSCs are bound by humanitarian law, whether their staff are civilians or combatants, and how the use of force in self-defence relates to direct participation in hostilities, a key issue for an industry that operates by exploiting the right to use force in self-defence. Throughout, the authors identify how existing legal obligations, including under state and individual criminal responsibility should play a role in the regulation of the industry.
