From the reviews: "Book, edited by Rudiger Wolfrum and Ulrike Deutsch, is based on a workshop which was held ... in Heidelberg in December 2007. ... incorporates not only the original presentations but also the corresponding high level discussions. Reading these discussions one gets a quick but thorough overview of possible positions and avenues which can be taken. ... a valuable overview of different views and approaches to a problem which needs to be solved in order to maintain a high standard of human rights protection in Europe."
