About this Event
A legal order without a codified constitution: The New Zealand experiment
New Zealand is one of the few countries that does not have a codified constitution. Among those few countries with uncodified constitutions, it is the only one with a founding treaty and an ongoing tradition of customary law. The Chief Justice will explore the history of New Zealand’s constitutional settlement—which, given its unique character, could be described as a constitutional experiment. She will discuss how it operates in the legal sphere, and the forces at work in its continuing evolution. Along the way she will note points of contrast with the Australian experience.
