The growth in cross-border investments in an increasingly globalised economy means that there are more international disputes between foreign investors and states than ever before. Investment treaty arbitration has thus become the preferred dispute resolution mechanism for resolving disputes with a state relating to foreign investment. However, securing a final arbitral award in this context is often only the beginning of a complicated process in enforcing arbitral awards against sovereigns and state entities. Spearheaded by leading arbitration practitioner Julien Fouret at Castaldi Mourre in Paris, this new title brings together more than 30 experts to provide both substantive analysis of recurring issues at the enforcement stage of awards and practical perspectives on how to enforce an award based on investment treaties. It explores enforcement issues ranging from the specificities of the International Centre for Settlement of Investment Disputes mechanism to the enforcement of interim relief and the issues of sovereign immunity and state entities; and addresses the means to enforce these types of award in practice. Valuable jurisdiction-specific information is provided for over 25 states, including coverage of the applicable international and domestic legal frameworks and reviews of the most recent practices. Whether you are an arbitration lawyer in private practice or a user of investment treaty arbitration, this title will provide you with holistic, practical and theoretical insight on the last and most important step of an arbitral process against a state or state entity.
