Book excerpt: Certain types of crime are increasingly being perpetrated across national borders and require a unified regional or global response to combat them. Transnational criminal law covers both the international treaty obligations which require States to introduce specific substantive measures into their domestic criminal law schemes, and an allied procedural dimension concerned with the articulation of inter-state cooperation in pursuit of the alleged transnational criminal. The Routledge Handbook of Transnational Criminal Law provides a comprehensive overview of the system which is designed to regulate cross border crime. The book looks at the history and development of the system, asking questions as to the principal purpose and effectiveness of transnational criminal law as it currently stands. The book brings together experts in the field, both scholars and practitioners, in order to offer original and forward-looking analyses of the key elements of the transnational criminal law. The book is split into several parts for ease of reference: Fundamental concepts surrounding the international regulation of transnational crime. Procedures for international cooperation against alleged transnational criminals including jurisdiction, police cooperation, asset recovery and extradition. Substantive crimes covered by transnational criminal law analysing the current legal provisions for each crime. The implementation of transnational criminal law and the effectiveness of the system of transnational criminal law. With chapters from over 25 authorities in the field, this handbook will be an invaluable reference work for student and academics and for policy makers with an interest in transnational criminal law.
