This excellent book is at once an authoritative treatise, a comprehensive, clear and quite detailed reference, and an informed discussion of the strengths and weaknesses of the international trading system. Focusing on GATT, it also gives major attention to American trade law and practice, including such troubling matters as major ambiguities and the way the fair trade laws have become a dangerous morass. As the international system is clearly "defective," Professor Jackson of the University of Michigan Law School says we must "worry . . . whether the 'trade constitution' can stand up to the stresses it is likely to face during the next few decades." He makes a number of suggestions as to how it can be strengthened.
