This article aims to continue the recent neo-Elyean turn in comparative constitutional scholarship by further exploring the role of the courts in supporting and protecting democracy. In so doing, it refines and develops my previous work on the topic, and applies this fuller version to a highly visible current dispute. The article first examines the underlying conception of democracy that comparative political process theory is designed to protect; namely, constitutional democracy. It asks what this is and what role courts have in supporting it. The article then introduces the idea of ‘semi-substantive review’ as an integral and output-oriented part of a comprehensive comparative political process theory, alongside and in addition to the types of more purely procedural review I primarily emphasized in my previous work. Finally, the article employs the recent, highly controversial judicial reforms in Israel as a case study in applying the criteria for, and limits of, court intervention in my account. It analyses whether, why and how, in the event that the deeply contested bills become law (as so far one did), judges would be justified in acting to support and protect constitutional democracy.
