Through sovereign immunity from enforcement, a state can evade its debt obligations. The economic significance of this immunity is therefore enormous and, in light of increasing state insolvencies, more relevant than ever. Given its considerable practical relevance, one might assume that a clear and easily assessable body of law has developed over time. However, this is not the case. Despite some consolidating trends in certain areas, it remains a fluid and highly complex subject that still raises numerous unresolved questions. This work addresses not only the general principles of sovereign immunity from enforcement but also existing problem areas, offering explanations and potential solutions.
