This panel explores questions of legisprudence from a transsystemic perspective. It examines the characteristics of “good“ legislation, focussing on intertwined questions of process and substance. Panellists will discuss the role of the participatory elements of law-making, including consultation and information-sharing. They will reflect on the function of parliamentary committees in the evaluation of legislation, and the need for continued monitoring of the impact of legislation after it has entered into force. The panel will also discuss the relationship between these procedures and the soundness of laws in a substantive sense. In particular, the relationship between the quality of the process and how courts review legislation on judicial review will be examined, paying particular attention to how this review occurs in different ways in common law and civil law jurisdictions.
