THE CARRIAGE OF DANGEROUS GOODS BY SEA by Cleopatra Elmira Henry. Frances Pinter (Publishers) Ltd., London (1985, x and 151 pp., plus 16 pp. Appendices and 5 pp. Index). Hardback £25. A perennial topic for debate is the extent to which international legal organizations can effectively regulate the behaviour of states in the international arena. This issue is considered here in the specific instance of regulation of the global carriage of dangerous goods at sea. This study examines in detail the work of one of the most effective international agencies, the International Maritime Organization, considering its mandate and methods for implementing controls on the transport of controversial toxins such as radioactive waste materials, together with the different responses of states in attempting to comply with or to deviate from such controls.
