There is a great degree of controversy on the proper complexion and role of general principles of law in the international legal order. Opinions range from total rejection of some types of principles to the most enthusiastic endorsement of principles as the necessary oil for the many complex wheels of the legal order. In this book one of the leading public lawyers of his generation explores the concept of good faith and its role in international law. Rather than offer a detailed, comprehensive examination, Kolb aims to map the true points of gravity of the principle of good faith in the international legal order. In so doing, he illustrates how the various legal institutions who operate in the sphere of public international law allow the principle of good faith to unfold.
