Casuistry in International Criminal Law

In this project the case law of international criminal courts is analysed and evaluated by using insights from casuistry. Casuistry is an age-old form of legal reasoning that is based on the thought that the law operates and develops in interplay with case-specific facts. From this perspective, the project assesses how international criminal courts apply substantive legal concepts – i.e. international crimes and modes of liability – to the facts of individual cases. This assessment provides further insights into the meaning and scope of substantive international criminal law and adds a new voice to existing debates on judicial reasoning.
