The World of Constitutionalism is Not Flat

Abstract In recent years, the emerging field of comparative constitutional law has been swept by a new approach with a scientific allure known as the Large-N approach. The methodology of this approach requires flattening the world of constitutional law by reducing the meaning of constitutional determinations into countable data. One of the difficulties in resisting this trend is that while many constitutional scholars have offered accounts that do not flatten the world of constitutional law, their methodology remains unarticulated and rarely discussed. Paul Kahn is one of the few scholars who offered an account of how to conduct non-doctrinal research of constitutional law. This Article aims to distil several principles of Kahn’s methodology, discuss its limitations, and demonstrate why it is superior to the Large-N approach. To achieve these goals, I chose to focus on three books on the German constitutional system that are based on dissertations written at Yale University, where Kahn teaches. Based on my discussion of these three books, I argue that Kahn’s methodology offers an approach which I dub the “Rich Picture” approach (or Rich-P). The Rich-P approach exposes that participants in a constitutional discourses understand constitutional materials, such as constitutional documents or judicial opinions, through a conceptual array that varies between legal orders. Without acknowledging the conceptual “eyeglasses” we wear when investigating constitutional determinations, measurements of the entire world of constitutionalism may lead to catchy soundbites and tweets, but to conclusions that are misleading at best.
