The present publication is the outcome of a research project undertaken at the Rheinische Friedrich-Wilhelms-Universität Bonn, which aimed to complete a comprehensive, comparative legal stocktaking and analysis of international restitution practice as well as its underlying concepts of justice. To this end, case material from Germany, Austria, the Netherlands, France, the United Kingdom and Switzerland was reviewed and systematized. Rules for just and fair solutions were abstracted and formulated, reflecting the current state of practice, and thus utilizable as an aid to argumentation for the decisive bodies. Commentaries elucidate the rules. Country reports explain practice in the respective jurisdictions. German edition
