Constant changes in administrative law and shifting political winds reinforce the need for an up-to-date volume that critically examines the law in its contemporary, as well as historical, context.

This fifth edition fully updates the law to examine recent High Court and other superior court decisions, particularly those relating to unreasonableness, sub-delegation, bias, jurisdictional error and government liability for damages in tort, including for misfeasance in public office.

These developments highlight the ever-evolving shape of administrative law. They underscore a central argument of this book – the necessity to examine the content and trajectory of administrative law in its political, administrative and socio-economic settings.
