This chapter examines the extent to which there is, or may be, accountability with regard to the exercise of such powers as a result of the administrative mechanism of judicial review. It examines the way in which judges, in exercising restraint, may hinder the bringing of successful review applications with regard to exercises of emergency powers. It also focuses on express attempts by the legislature to limit the availability of judicial review, in the form of privative clauses, and the possible impact of those attempts on the review of emergency powers. Doctrines relating to ‘justiciability’, ‘act of state, ‘deference’, and procedural fairness are highlighted.
