This Webinar introduced the ongoing Project:  Routledge Handbook of Constitutional Law in Greater China. Edited by three CUHK LAW members Ngoc Son Bui, Stuart Hargreaves, and Ryan Mitchell, this Handbook aims to provide a comprehensive survey of important issues of constitutional law in mainland China, Hong Kong, Macau, and Taiwan; and critically discuss leading views on these issues. In the Webinar, the three editors discussed comparative issues related to the Handbook. Professor Hargreaves discussed national security and the overseas judges in Hong Kong and Macau. Professor Mitchell discussed the evolution of the People Republic of China’s Constitution over time and its changing roles in relation to the state and society. Professor Bui discussed comparative constitutional law scholarship’s recent engagement with China’s Constitution. Professor  Mara Malagodi  moderated the webinar and hosted a Q&A session with the audience at the end.
