Final Report Summary - IMECAJ (The implementation of international criminal justice: Deciphering a (more effective) way forward through the competing tensions) Overall, during the 15 months to 30 September 2014, the ER has made excellent progress in his research activities, focusing in particular on the practical jurisprudence and structural developments at the various mechanisms of international justice, and their ramifications and impact upon the work of those institutions and the broader perceptions of their ‘effectiveness’. Most of the analysis and research for these issues is complete. In this regard, the ER has made very significant progress in completing the first three principal objectives of the research, as set out in the original research application. As at 30 September 2014, the ER was in working on the assimilation of the results of his research, with a view to the timely completion of the final principal research objective.Over the 15 month period, the ER actively collaborated on various aspects of his research with institutional courts (primarily in The Hague), Government agencies, NGOs, academics, practitioners and other stakeholders who are interested and participate in an analysis of the work of the mechanisms of international criminal justice. This collaboration involved transfer of knowledge, joint publication and research outputs and teaching/training activities involving colleagues throughout Europe. As part of the outreach/outputs in this project, the ER collaborated in written and published research during this period with researchers in several countries in Europe (including Austria, Belgium, Bulgaria, Denmark, Finland, France, Germany, Greece, Italy, The Netherlands, Portugal, Spain, Sweden, United Kingdom), and also from other countries (Argentina, Australia, Canada, New Zealand, Nigeria, Russia, Sierra Leone, Singapore, South Africa, Uganda, United States). These collaborative efforts have all been undertaken with appropriate visibility and acknowledgement of the generous support of the EC / EU through the Marie Curie Fellowship Programme. The diverse nature of these activities has served to broaden the impact and consideration of various aspects of the research.
