This work forms a companion volume to Legal Advisers and Foreign Affairs published three years ago in a similar format, under the same editorship and auspices, and reviewed by the present writer in this Journal for January, 1965. Like its predecessor it is the outcome of a symposium sponsored by the American Society of International Law under the Chairmanship of its President, Professor Brunson MacChesney, which took place at Bellagio in August, 1965, the participants being members not of government legal services but of the analogous services of representative international organizations. In sponsoring the Bellagio Conference the Society was following up and extending its exploration of the rôle played by the “service” legal adviser in the international field—a rôle which, as the present reviewer previously had occasion to point out in connection with the functions of legal advisers to governments and government departments, has certainly been neglected and, because neglected, to some extent misunderstood.
