National Security Law is a burgeoning field of concern for Government, security agencies, civil rights monitors, and the Australian public. As both the nature of threats (represented by, for example, the 11 September 2001 attacks in the US, or the rise of cyber security as a major national security concern) and the concept of ‘security’ (such as biosecurity) have evolved, legal responses have similarly evolved. This course offers a broad brush across a number of issues concerning national security law. The course will commence with a series of building blocks (heads of power, conceptions of security, historical background). This will then allow more detailed exploration of a series of institutional issues (such as the legislative arrangements for important national security institutions, and the ‘security law’ making and monitoring process), practical issues (such as use of force, and use of classified information in prosecutions), and thematic issues (such as the national security – civil rights balancing debate).
