The Ecuadorian government, alongside with Bolivia and Venezuela, decided to denounce the Convention on the Settlement of Investment Disputes between States and Nationals of Other States. According to government officials, such action was taken to avoid being subject to the jurisdiction of international arbitration tribunals. As jurisdiction over investment claims has its basis on various legal instruments such as Bilateral Investment Treaties and not just the ICSID Convention, the legal consequences of the denunciation might not fulfill the governments’ goals. This book does a holistic analysis of the withdrawal process and its consequences. Historical, political, and legal events are reviewed through the chapters, where international law crosses paths with political sciences. It is a work on international law that intends to add some clarity and ideas to an issue of paramount importance for denouncing states and more broadly, all member States of the ICSID Convention.
