The Rwandan genocide of 1994, wars in the Democratic Republic of Congo, and armed conflict in the Central African Republic were characterized by sexualized violence, atrocities international observers often describe as “unspeakable.” Yet international criminal tribunals rely on the testimonies of survivors to prosecute those responsible for genocide, crimes against humanity, and war crimes. To show how the unspeakable becomes legal testimony, this talk examines encounters between court investigators and survivors of atrocity, witness testimony in international trial chambers, and the often-unseen work of interpreters in international justice. Tribunal workers’ formal routines, informal practices, and the day-to-day tasks of international justice reveal storytelling both as border-crossing and as gendered labor. I argue that unequal power relations between tribunal staff, their intermediaries, and survivors both animate and confound the work of gender justice at international courts.
