This book addresses concerns with the international trade and investment dispute settlement systems from a statist perspective, at a time when multilateralism is deeply questioned by the forces of mega-regionalism and political and economic contestation. In covering recent case law and theoretical discussions, the book’s contributors analyze the particularities of statehood and the limitations of the dispute settlement systems to judge sovereign actors as autonomous regulators.
