This book deals with the ongoing reform process for investor-state dispute settlement in UNCITRAL Working Group III, in particular the proposal to create a multilateral investment tribunal (MIC). The book covers key elements of the MIC proposal, such as the institutional framework of the court, the design of an appeals mechanism, the use of class-law settlement procedures, and the establishment of an advisory center for developing countries. In addition, the selection and appointment of judges is discussed. It also explores the following questions: How can the MIC be integrated into the existing ISDS system? How can the implementation of its decisions be ensured? Each chapter highlights the legal issues to be discussed and places them in a larger context to offer an understanding of the core questions and how they are related to each other.
