The immunity or exemption enjoyed by States from legal proceedings before foreign national courts is a crucial area of international law. On the basis of an exhaustive analysis of judicial decisions, international treaties, national legislation, government statements, deliberations in international organisations as well as scholarly opinion, Xiaodong Yang traces the historical development of the relevant doctrine and practice, critically analyses the rationale for restrictive immunity and closely inspects such important exceptions to immunity as commercial transactions, contracts of employment, tortious liability, separate entities, the enforcement of judgments, waiver of immunity and the interplay between State immunity and human rights. The book draws a full picture of the law of State immunity as it currently stands and endeavours to provide useful information and guidance for practitioners, academics and students alike.

Ours is a world in which the volume of the external trade of the vast majority of nations has greatly expanded and continues to be on the rise. Transnational intercourse of all kinds is now a feature of an interdependent world economy in which no nation can afford to stand aloof from a market-place which has assumed global dimensions. It is also a world where many nations, and not only of the Socialist bloc, conduct some of their transnational business themselves, or else they entrust it to state-owned cor porations and to agencies of the state. In these circumstances it becomes of prime importance to know whether a foreign state or an agency or instrumentality thereof can be sued before the local courts and, if so, whether the final judgement obtained can be enforced against the funds or property of the judgement debtor. The question of the immunity of states from suit and from execution is thus one of direct practical relevance not only to the legal profession but also to governments and the business and banking communities all over the world. The economic effects of a particular legal stand on state immunity are obvious. The position of national courts on state immunity can either attract more business or discourage further dealings with foreign states or their agencies. It can thus affect the balance of payments and, in general, the role the country plays in the world market.

The doctrine of state immunity bars a national court from adjudicating or enforcing claims against foreign states. This doctrine, the foundation for high-profile national and international decisions such as those in the Pinochet case and the Arrest Warrant cases, has always been controversial. The reasons for the controversy are many and varied. Some argue that state immunity paves the way for state violations of human rights. Others argue that the customary basis for the doctrine is not a sufficient basis for regulation and that codification is the way forward. Furthermore, it can be argued that even when judgments are made in national courts against other states, the doctrine makes enforcement of these decisions impossible. This fully restructured new edition provides a detailed analysis of these issues in a more clear and accessible manner. It provides a nuanced assessment of the development of the doctrine of state immunity, including a general comprehensive overview of the plea of immunity of a foreign state, its characteristics, and its operation as a bar to proceedings in national courts of another state. It includes a coherent history and justification of the plea of state immunity, demonstrating its development from the absolute to the restrictive phase, arguing that state immunity can now be seen to be developing into a third phase which uses immunity allocate adjudicative and enforcement jurisdictions between the foreign and the territorial states. The United Nations Convention on Jurisdictional Immunities of states and their Property is thoroughly assessed. Through a detailed examination of the sources of law and of English and US case law, and a comparative analysis of other types of immunity, the authors explore both the law as it stands, and what it could and should be in years to come.

In this insightful book, Katherine Reece Thomas explores the constantly evolving nature of state immunity, providing a nuanced analysis of the tension between private and public law. The current rules on the commercial activity exception to state immunity are examined, in both international and domestic law settings, using recent case studies from key jurisdictions including the UK and the US.
