As a response to the Symposium on the International Criminal Tribunals for the former Yugoslavia and Rwanda published by the American Journal of International Law on the occasion of the tribunals’ closure, this AJIL Unbound Symposium intends to broaden the debate on the “legacies” of those courts. The AJIL Symposium contains articles on the creation of the International Criminal Tribunal for the former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda (ICTR); the ad hoc tribunals’ jurisprudential contributions; and their extra-legal impacts and legacies. The concept of “legacy” is itself contested and the appropriateness of the courts’ own efforts to consolidate it may be questioned, especially as they have barely ended (or are about to end) their work. Nevertheless, their over two decades of existence does provide an occasion to assess all they have done and not done, and have affected, intentionally and unintentionally. Against that background, we have invited a group of scholars to respond to the AJIL Symposium and to reflect upon the work of the tribunals with a view to enriching the debate with more voices, from different regions, from different interest groups, and from different disciplines.
