The main objective of the course is to introduce students to the mechanisms of criminal law enforcement in a modern globalized setting. With the development of a modern society, traditional national criminal law enforcement mechanisms are becoming more and more supplement by additional – international and European – law enforcement mechanisms. The objectives of the course are to help students understand the reasons for such development, introduce them to mechanisms of European and international cooperation in criminal matters, their subjects, principles and procedures, and teach them how to interpret and apply these mechanisms properly.
