I should like to express my gratitude to three eminent scholars who have been kind enough to go through my manuscript, viz. Professor Philip C. Jessup of Columbia University, Professor Gerhard Leibholz of the University of Göttingen, a member of the German Constitutional Court, and Professor Marcel Waline of the Faculty of Law in Paris. Each of them has checked the particular section that applies to the public law of his own country. Their comments have proved of the greatest value.
I need hardly say that the whole work, including such criticisms and appraisals of legal and ideological standpoints as it contains, is entirely my own responsibility.
I express my gratitude for the NATO Fellowship which enabled me to undertake the necessary studies abroad, and for the grant made by the Norwegian Research Council for Science and the Humanities to cover the expenses of the publication.
