The fight against today's new forms of criminality, across Europe and beyond, can only succeed if we have the necessary tools, in particular through effective mechanisms dealing with extradition. For over fifty years, the Council of Europe has been developing a set of instruments dealing with extradition, be it in the form of conventions or resolutions and recommendations to member states. This publication presents notes and comments on the Council of Europe's legal instruments on extradition. It includes the current status of the case law of the European Court of Human Rights on extradition matters and on other transnational criminal proceedings. It also brings together the non-binding instruments on extradition adopted by the Council of Europe's Committee of Ministers. Practitioners, policy makers and researchers dealing with extradition matters will find this publication a useful and up-to-date reference document.
