This book has addressed the phenomenon of multi-actor human rights protection at the International Criminal Court, focusing on the protection of accused and witnesses. The discussion was divided over three parts. Parts I and II considered, respectively, situations involving the ICC and States Parties, and situations involving the ICC and its host State. The aim of these two parts was to identify the relevant obligations incumbent upon each actor in each of the multi-actor situations, and thereby map their respective roles and tasks. With this information, it was then possible to comment on the potential problems that can arise for human rights protection as a result of the involvement of multiple actors. In Part III, solutions were proposed for how these problems might be mitigated or resolved, whether through changes in the current legal framework or institutional innovations.
