This 2002 book, now reissued in paperback, describes and critically analyses the formal constitutional changes that have taken place in the Asia-Pacific region, embracing the countries of East and South East Asia and Pacific Island states. In examining the variety amongst constitutional systems operating in the region, it asks several key questions: What constitutional arrangements operate in the region and how can their fundamental differences in structure and operation be explained? How do social, political and economic factors limit the effects of the constitution in place? What lessons exist for the practice of constitutionalism elsewhere? The aim of the book is to ground the idea of constitutionalism in local and global practices, and, through examining these practices, to identify significant challenges to the workings of contemporary constitutional orders.
