摘要:The paper observes the emergence of an international order of criminal prosecution in Europe from the late 18th century, which was characterised by two ambiguous developments: nation-based criminal law systems on the one hand and an increasing demand for international, transborder co-operation in matters of criminal law and criminal justice on the other. For with increasing migration, economic transactions and political dissidents, new crimes and threats of order and security, which could not only be handled within the national criminal systems, evolved. Thus the main fields in which a new international order in criminal matters was developed over the course of the 19th century were extradition, asylum and mutual assistance, as shaped by international treaties, domestic national laws and by international legal discourses. Based on different national legal orders and traditions, nearly every country established slightly different legal regulations and instruments, though in the long run it was inevitably the establishment of rules and instruments of transborder co-operation and mutual assistance in criminal matters which would at last lead to an international – and fragile – order of criminal prosecution. In this regard the project that will be presented in the conference makes a wide-ranging topic for comparative legal history in the field of criminal as well as international law.
