The monograph considers the individual and joint dissertations, separate opinions and dissenting opinions that British judges Sir Gerald Fitzmaurice, Sir Humphrey Waldock, Sir Robert Jennings, Dame Rosalyn Higgins and Sir Christopher Greenwood appended to Judgments and Advisory Opinions of the International Court of Justice. It provides information of the life of, and reviews some of the scholarship of, these judges. In the final chapter, the author endeavours to identify characteristics of the British judges of the International Court of Justice that are shared by some of all of these five jurists – together with their predecessors at the Court, Baron Arnold McNair and Sir Hersch Lauterpacht.
