This Presentation will introduce the concept of “towering judges”, which is the subject of a forthcoming edited volume. The volume discusses nineteen judges of apex and constitutional courts from fifteen jurisdictions. Within their particular political, historical, and institutional settings, each of these judges made a significant impact on the trajectory and development of constitutional law. The Presentation will define the concept of “towering judges”, discuss different dimensions along which judges may tower, explore their different modes of operation, and identify the conditions that are conductive to the rise of such judges. It will conclude on a cautionary note, by discussing some limitations of the study and the dangers that towering judges may pose to constitutional systems.
