As the current immunity regime produces unfair results at the normative level, this book addresses the question of how to feasibly restrict State immunity from jurisdiction in case of gross violations of human rights, in light of States’ resistance to a general jus cogens/human rights exception. The central thesis of the book is that justice may be achieved by a more limited human rights exception to immunity, based on an enlarged forum tort exception. To build such an exception, the book draws on private international law rules on jurisdiction, bringing together the disciplines of public and private international law.
