Should state immunity from jurisdiction be denied to states that violate fundamental human rights in breach of international law? This article critically discusses three analytical approaches which can be used to answer the question at the level of international law. These approaches are derived from a review of principles of state immunity and fundamental human rights, including ius cogens. The article goes on to examine why the results dictated by these approaches at the level ot international law may not be reflected by municipal legal systems, using US domestic statutes and case law as an example of how a domestic legal system has dealt with this question.
