The Rise of Investment Treaties and ISDS in the 1990s and Since
In the early 1980s, many countries had not signed investment treaties or joined the ICSID Convention. Neither was there any ISDS practice. This situation changed quickly, however, as the views of the norm entrepreneurs of the 1950s and 1960s became part of the global consensus on development thinking. In the 1990s, the World Bank and UNCTAD put themselves at the forefront of efforts to promote investment treaties and ISDS, a task for which they had the support of organizations such as the American Bar Association. The investment treaty network rapidly expanded, most states joined ICSID, and the first ISDS cases emerged. Some arbitrators acted as pioneers of a new legal field, while others wrote in celebration of the fact that the proposals of the 1960s had now become law. Crucially, they also resolved the disputes in the background of the legal imagination.
