Sovereign Choices and Sovereign Constraints

Abstract

Investment arbitrators rely on sovereignty for their legal status just as investor-state disputes usually stem from disagreements about the role of the state in society. As a result, investment arbitration is a vehicle for the exercise of sovereign authority and a site for contesting sovereign choices. This book investigates and evaluates the decision-making record and policy trajectory of international investment arbitration, from theoretical, doctrinal, and empirical perspectives. It analyses the extent to which the system used to resolve disputes impacts on the role of government, affecting diverse constituencies, as opposed to limiting itself to case-specific disputes between a single business enterprise and state entity. The book provides a review of known awards in order to determine the types of government measures that have triggered disputes. It investigates how investment arbitrators have exercised their authority in recent case law. It provides a review of the approaches adopted in the reasoning of investment treaty tribunals on questions of judicial deference and respect for sovereign decision-makers. In doing so, it determines whether investment tribunals have taken a predominantly assertive approach to investor protection, without regard to their relative lack of accountability, capacity, or proximity in some cases. This approach does not sit comfortably with the relative restraint seen by domestic and international courts in similar contexts.
