This collection of essays honours Gabrielle Kirk McDonald, the International Tribunal's second President and the presiding judge in the first international war crimes trial in modern times. Written by judges, legal advisers and practitioners, it is the first comprehensive overview of the procedural and evidentiary aspects of the International Tribunal's work. These essays will be of great assistance to all of those who are following the work and development of the International Tribunal, particularly practitioners, academics and students. This collection is thus a valuable addition to the literature on the International Tribunal and a worthy tribute to President McDonald and her work.
