What is the role of Transnational Networks and NGOs in achieving transitional justice for the Rohingya? How do NGOs impact on the legitimacy of the existing transitional justice avenues? The chapter provides a comprehensive and critical examination of how transnational networks engaged with transitional justice within the context of the Rohingya. It also opens the empirical part of the Myanmar case study, mapping a transnational network of international NGOs and Rohingya in the diaspora. More specifically, it critically analyses the different NGO actors involved in the Rohingya cases—the ICC Investigation into the Bangladesh/Myanmar situation, the International Court of Justice case and the universal jurisdiction case in Argentina. The chapter shows that whilst the cases in The Hague are considered as vital in the quest for accountability and respect for rights in Myanmar, they are not in themselves the only viable alternatives for transitional justice, as illuminated in NGO practice and discourse. Nonetheless, it is argued that transnational NGO networks have enhanced the legitimacy of The Hague-based mechanisms, before the Rohingya victims. In doing so, the book paves the way for analysing how such global mechanisms could influence hegemonic structures of global governance under the purview of transitional justice.
