The Wilson Center hosted a panel to examine practical suggestions for reform of the current system of resolving international investment treaty disputes. The increase in cases against States and their challenge to public policy measures has generated a strong debate, usually framed by complaints about a perceived lack of legitimacy, consistency and predictability. While some ideas have been proposed for improvement, there has never before been a book systematically focusing on constructive paths forward. The new volume launched with this panel discussion features 38 chapters by almost 50 leading contributors, all offering concrete proposals to improve the ISDS system for the 21st century.
