Questions on the relevant topics are proposed for discussion by the Commission, and some issues are outlined for shaping the discussion. One of the issues for discussion by the Commission is specific modalities of international cooperation in criminal matters. Issues to be addressed on this topic are extradition and mutual legal assistance; international cooperation for the purposes of confiscation; and the use of other forms of international cooperation in criminal matters. A second major issue to be discussed at the Commission's 23rd session is how to manage international cooperation in multiple legal proceedings where the same individual is involved. Multiple legal proceedings that involve the same individual or individuals pose a series of challenges in the prosecution of organized crime in both national and international contexts. A third issue to be discussed is the implementation of international instruments that contain provisions on international cooperation in criminal matters. Other issues to be discussed are learning from experiences at the regional level; international cooperation in combating new and emerging forms of crime; the provision of technical assistance; and ways and means to avoid piecemeal and fragmented solutions to criminal matters that require international cooperation. For each of these seven topics, background information is provided, followed by a series of questions for discussion on the topic.
