The Italian Yearbook of International Law aims at making accessible to the English speaking public the Italian contribution to the practice and literature of international law. Volume XI (2001) is organised in three main sections. The first contains doctrinal contributions featuring inter alia articles on the international law aspects of the 2001 Italian constitutional amendment, the judicial enforcement of customary human rights law and the issue of overlapping dispute settlement regimes in light of the Southern Bluefin Tuna case. A special focus of this volume is the increasingly important field of international cultural property law. Three articles deal, respectively, with the 2001 UNESCO Convention on Underwater Cultural Heritage, the 1999 Protocol to the Hague Convention on the Protection of Cultural Property in the Event of Armed Conflict, and with the intersection between cultural property law and human rights. As in the previous year, Volume XI (2001) contains a subsection devoted to surveys on the activity of the World Trade Organization, the International Tribunal for the Law of the Sea, the International Law Commission and the European Court of Human Rights. The second section covers the Italian practice in the areas of 1) judicial decisions (including significant decisions, such as the final decisions on the Baraldini case and on the return to the Italian territory of the male descendants of the House of Savoy), 2) diplomatic and parliamentary practice (such as the parliamentary debates relating to the 11 September terrorist attacks on the US), 3) treaty practice, and 4) national legislation. The third section contains a systematic bibliographical index of Italian literature in the field of international law and a book review. The volume ends with an analytical index for ready consultation which includes the main judicial cases and legal instruments cited throughout the Yearbook.
