International investment law is one of the fastest growing areas of international law. It has led to the signing of thousands of agreements, mostly in the form of investment contracts and bilateral investment treaties. Also, in the last two decades, there has been an exponential growth in the number of disputes being resolved by investment arbitration tribunals. Yet the legal principles at the basis of international investment law and arbitration remain in a state offlux. Perhaps the best illustration of this phenomenon is the wide disagreement among investment tribunals on some of the core concepts underpinning the regime, such as investment, property, regulatory powers, scope of jurisdiction, applicable law, or the interactions with other areas ofinternational law.The purpose of this book is to revisit these conceptual foundations in order to shed light on the practice of international investment law. It is an attempt to bridge the growing gap between the theory and the practice of this thriving area of international law. The first part of the book focuses on the ''infrastructure'' of the investment regime or, more specifically, on the structural arrangements that have been developed to manage foreign investment transactions and the potential disputesarising from them. The second part of the book identifies the common conceptual bases of an array of seemingly unconnected practical problems in order to clarify the main stakes and offer balanced solutions. The third part addresses the main sources of ''regime stress'' as well as the main legalmechanisms available to manage such challenges to the operation of the regime.Overall, the book offers a thorough investigation of the conflicting theoretical positions underlying international investment law, testing their worth by reference to concrete issues that have arisen in the jurisprudence. It demonstrates that many of the most important practical questions arising in practice can be addressed by a carefully dosed resort to theory.

It is an attempt to bridge the growing gap between the theory and the practice of this thriving area of international law.

The second part of the book identifies the common conceptual bases of an array of seemingly unconnected practical problems in order to clarify the main stakes and offer balanced solutions.

The International Law of Investment Claims considers the distinct principles governing the prosecution of a claim in investment treaty arbitration. The principles are codified as 54 'rules' of general application on the juridical foundations of investment treaty arbitration, the jurisdiction of the tribunal, the admissibility of claims and the laws applicable to different aspects of the investment dispute. The commentary to each proposed rule contains a critical analysis of the investment treaty jurisprudence and makes extensive reference to the decisions of other international courts and tribunals, as well as to the relevant experience of municipal legal orders. Solutions are elaborated in respect of the most intractable problems that have arisen in the cases, including: the effect of an exclusive jurisdiction clause in an investment agreement with the host state; reliance on the MFN clause in relation to jurisdictional provisions; and, the legitimate scope of derivative claims by shareholders.
