The purpose of this study has been to investigate the prospects for identifying and prosecuting individuals suspected of war crimes, within the process of exclusion from refugee status under article 1F(a) of the 1951 Refugee Convention, and using subsequent mechanisms for extradition or prosecution in international criminal law. A number of principles within human rights law and public international law have been advocated by the UNCHR and several human rights NGOs as necessary for a thorough application of the exclusion clauses; one that takes individual responsibility into account and upholds the aims and purposes of the exclusion clauses. There is a discussion as to whether specialised or accelerated exclusion procedures are justified for reasons of security and efficiency, or if they put the rights of the individual at risk and limit the opportunities for gathering information to support investigation and prosecution of the crime in question. Apart from the instruments of asylum law and procedure that have emerged within the EU harmonisation process, there are no general, binding rules on the procedural aspects of the exclusion clauses. One principle that regulates the consequences for the individual of exclusion from refugee status and decisions on extradition is, however, the principle of non-refoulement.
