The criminal justice sector response is an important aspect of an overall, rule of law-based approach to counter-terrorism. ICCT has worked on a range of issues related to the criminal justice sector, including the close monitoring of a number of terrorism trials and commentary on legal aspects of proceedings and judgements. Next to this, the Centre is implementing a capacity building project on the protection of witnesses and the use of intelligence in terrorism-related court cases to enhance the criminal justice sector response. Similarly, ICCT has analysed the potential role of armed forces in providing evidence for terrorism-trials. ICCT also looks beyond the judicial aspects of terrorism cases and explores the wider, societal implications of trials and their performative power in a seminar series entitled “Terrorists on Trial”.
