| 概要≠ | Longitudinal comparative legal analysis examines how legal rules, doctrines, or institutions develop and diverge across two or more legal systems over an extended period. By combining the spatial dimension of comparative law with the temporal dimension of longitudinal research, it captures not just differences between jurisdictions at a single point but the trajectories of legal change — convergence, divergence, transplantation, and resistance — over years or decades. | Comparative legal analysis is a structured research method that examines how two or more legal systems — whether national, regional, or supranational — address a common legal problem. By placing rules, doctrines, and judicial decisions side by side, researchers identify convergences, divergences, and the underlying societal, historical, and political forces that shape legal solutions. The method is foundational to law reform, harmonisation efforts, treaty drafting, and academic legal scholarship. |
