This work provides indispensable access to an intricate and complex network of legal rules on extradition found in multilateral treaties and conventions, with specific emphasis on extradition in the Americas. It covers the historical development of the multilateral approach and presents a survey of the steps taken and work accomplished by organs of the Organization of American States with respect to updating the multilateral rules on extradition within the inter-American system. The analysis covers provisions of multilateral conventions of worldwide scope whose purposes are to prevent or repress specific categories of offences and compares the Inter-American Convention on Extradition with other multilateral treaties and conventions on that matter. The materials compiled in this volume give a welcome insight in the codification of law and constitute a fundamental tool for judicial cooperation in the Inter-American context.
