This publication contains summaries of 33 cases dating from the late nineteenth century to the present which have been selected because they give an insight into the evolution of the law of the sea and the range of issues involved in this important aspect of international law. The cases selected include judgements given by the Permanent Court of International Justice, the Central American Court of Justice, the International Court of Justice and the International Tribunal for the Law of the Sea, as well as awards rendered by arbitral tribunals and a special commission.
