This paper will consider the practical settlement of conflicts of jurisdiction both in relation to the forum for prosecution and transfer of proceedings. The corollary of free movement of people is free movement of judgments, sentences and related powers of investigation and prosecution. Cross border crime requires to be addressed by equipping law enforcement and prosecution authorities with mechanisms to ensure the public interest in the investigation and prosecution of crime is met. The starting point for any consideration is the place where the criminal conduct took place. Sometimes the crime is such that criminal jurisdiction will be fixed - such as theft of property, crimes of violence - where others have an impact or criminal conduct in more than one jurisdiction - drug importation, major transnational drug dealing, human trafficking, terrorism.
