What was his approach? What does it say about his view on the law and the way procedures at international criminal tribunals ought to be conducted? How influential was this Dissenting Opinion, was he followed in later majority decisions? The contribution will be a challenging attempt to characterise and to assess the individual contribution of Judge Schomburg to the development of international criminal law.
