To mark the fiftieth anniversary of the International Court of Justice, a distinguished group of international judges, practitioners and academics has undertaken a major review of its work. The chapters discuss the main areas of substantive law with which the Court has been concerned, and the more significant aspects of its practice and procedure in dealing with cases before it. It discusses the role of the Court in the international legal order and its relationship with the political organs of the United Nations. The thirty-three chapters are presented under five headings: the Court; the sources and evidence of international law; substance of international law; procedural aspects of the Court's work; the Court and the United Nations. It has been prepared in honour of Sir Robert Jennings, judge and sometime President of the Court.
