Amazon.com description: Product Description: This book surveys and analyses the nature of FET as a ""new"" rule of customary law that is non-contingent and absolute in that it protects a given entity irrespective of the treatment which may be accorded to others. The author explores whether the often-heard criticism of the international investment protection regime is justified. The overarching questions are: Does the system`s mixture of private arbitration and public law indeed undermine accountability and independence in judicial decision-making? Does it trump principles of legislative supremacy and, in the end, alter a central tenet of representative democracy?
