National Security Constitutionalism in the Commonwealth Five Eyes States - Hardcover

This book examines the constitutional treatment of national security in the UK, Canada, Australia and New Zealand.

These four states share their Commonwealth heritage and are members, alongside the USA, of the Five Eyes intelligence-sharing alliance. The book takes a comparative approach to the institutions through which, and tools with which, these four states seek to protect their national security against the threats of both terrorism and hostile state activity and how they have evolved over time. It identifies and examines the various specialised institutions, inside and outside of legislatures, which have grown up to oversee the exercise of public power for national security purposes while maintaining the required secrecy. It argues that the extent of the borrowing and sharing between these jurisdictions in the domain of national security, now and in the past, permits us to talk about a Commonwealth model of national security constitutionalism.
