I would like to thank the Society of Legal Scholars (UK) for their generous support of my sabbatical visit to Columbia Law School in 2011 where most of the manuscript for this book was written. I would also like to express my appreciation to the Visiting Scholars of Columbia Law School and the Vale Columbia Center on Sustainable International Investment for assisting with the development of some of the central themes of this project. Finally I would like to thank Professor Peter van den Bossche of Maastricht University who provided valuable insight and guidance as the supervisor of my PhD thesis upon which much of this book was based.
