With regard to the investigation and the court, where does jurisdiction lie with regard to the likes of EU countries and countries outside the EU such as the UK? Can the people who are being investigated or brought to court move jurisdiction to another state outside the EU such as the UK and look for his or her case to be moved to that state if he or she is being prosecuted in an EU state? Can a person from the UK who is being prosecuted in an EU state move the case to his or her own jurisdiction, which is the UK?
