The monograph brings together climate protection, climate litigation, democratic processes and legal theory. It assesses how climate-related judicial review impacts liberal democracy, with particular attention to the separation of powers. Based on a selection of significant climate cases, the book analyses the stakes, obstacles, and dangers of courts deciding climate protection cases. Drawing on the work of Frank Michelman and Mark Tushnet, it develops a mode of climate-related judicial review that aligns with the fundamental principles of democracy. This monograph serves as a valuable resource for scholars and practitioners, including environmental lawyers, judges, policymakers, climate litigators, and legal thinkers.
