Since the end of the Cold War, states have become increasingly engaged in the suppression of transnational organised crime. The existence of the UN Convention Against Transnational Organised Crime and its Protocols demonstrates the necessity to comprehend this subject in a systematic way. Synthesizing the various sources of law that form this area of growing academic and practical importance, this book provides readers with a thorough understanding of the key concepts and legal instruments in international law governing transnational organized crime. The volume analyses transnational organised crime in consideration of the most relevant subareas of international law, such as international human rights and the law of armed conflict. Written by internationally recognized scholars in international and criminal law as well as respected high-level practitioners, this book is a useful tool for lawyers, public agents, and academics seeking straightforward and comprehensive access to a complex and significant topic.
