This book arose out of a symposium held in Bali, Indonesia, in May 2013, at which the authors engaged in lively debate concerning the question of codifying contract law. As reflected in this book, the authors’ viewpoints were many and varied, which made for wonderful discussions in Bali and, it is hoped, will provide the impetus for on-going debate and discussion for readers of this book. We would like to sincerely thank all of the authors, not only for their contributions but also for their excellent company as we enjoyed together the Balinese hospitality of The Mansion, Ubud. Thanks also to Griffith Law School for generously funding the symposium, and most particularly to the Griffith Law School Dean, Professor William Macneil and Griffith Law School Deputy Head Research, Professor Brad Sherman, for their support. Special thanks is due to the Griffith Law School Manager, Carol Ballard and her assistant, Madonna Adcock, for their hard work in making sure that everything ran smoothly in Bali. Finally, we would like to say how much we have enjoyed working together on this project, having been friends and colleagues for some years now with the intention of combining efforts at some point, but never really seizing the opportunity until now. It has truly been a pleasure.
