Introduction
The role of the business leaders, bankers, and lawyers who promoted investment treaties and ISDS in the post-World War II period remains controversial. The introductory chapter argues that these norm entrepreneurs and their professional associations created a legal imagination about foreign investment relations which remains alive and well in both international investment law and ISDS awards. Their contribution to the progressive development of the law consisted of ideas as much as practice, particularly the way in which they collated their ideas into a vision of foreign investment relations. The chapter introduces the main features of this legal imagination, including the relevance of certain interpretations of property and contracts. It claims that grasping this imagination calls for a transnational law method, and concludes with an overview of the book.
