An Emerging International Criminal Law Tradition: Gaps in Applicable Law and Transnational Common Laws

This thesis critically examines the origins and development of international criminal lave to identify the defining features of this emerging legal tradition. It critically evaluates the experimental approach taken in Article 21 of the Rome Statute of the International Criminal Court, which attempts to codify an untested normative super-structure to guide this legal tradition. International criminal law is a hybrid tradition which seeks legitimacy and answers to difficult questions by drawing on other established legal traditions. Its development at the confluence of public international law, international humanitarian law, international human rights law and national criminal laws has resulted in gaps in difficult cases with no clear answers. These lacunae have been filled by recourse to judicial discretion, exercised consistent with Patrick Glenn's theory of transnational common laws, and by privileging one of the competing aims of international criminal law: enhancing humanitarian protection versus maximizing fairness to the accused.
