The International Criminal Tribunals for Rwanda (ICTR) and the Former Yugoslavia (ICTY) have delivered landmark jurisprudence but little attention has been paid to the courtrooms which produce these decisions or the witnesses upon whose testimonies such legal developments are fundamentally based. Research on domestic criminal courts has found that victims often prioritize procedural justice (i.e. trial procedures) over distributive justice (i.e. trial outcomes) but scholars have yet to extend analyses of procedural justice to international law. This paper provides an initial exploration of procedural justice through evidence collection in an international criminal courtroom. The paper is grounded in three months of daily trial observations at the ICTR and the ICTY. An especially salient discovery of this preliminary fieldwork was the emotional upset that witnesses frequently expressed when they were unable to accurately answer certain types of questions and seemingly objective inquiries. The paper builds on this preliminary finding by analyzing transcripts of victim-witnesses testimony at the ICTR's Muhimana trial. Findings suggest that evidence of genocide, crimes against humanity, and war crimes - commonly collected years after commission of the crimes in question - must be elicited in particular ways if accuracy is to be achieved and procedural justice served. Specifically, evidence collection procedures in international criminal courtrooms must take into account fundamental components of the culture in question and remain sensitive to the ways in which trauma influences detail recollection.
