What challenges do Australian constitutional law, theory, and practice each face now that globalisation is eroding the sovereignty of nation-states? Works on Australian constitutionalism tend to assume that the centuries-old tradition of national sovereignty will continue. This book systematically discusses both constitutionalism and globalisation in tandem and analyses how each affects the other. Three key themes are reflected in the book's three parts: Whither National Sovereignty, Constitutional Structures, and Individual and Minority Rights. The first discusses the decline of the "external" power of national governments relative to international organisations and NGOs. The second focusses on the declining "internal" power of national governments relative to legislatures, in particular Upper Houses, and to sub-national governments. The third part charts the declining power of national governments relative to the citizens and minority communities they govern.
