The 2001 Cape Town Convention on International Interests in Mobile Equipment and Aircraft Protocol represents one of the most ambitious and imaginative private commercial law projects ever to have been concluded. By providing an international legal regimen for security and related interests in aircraft objects, railway rolling stock, and space assets, the Convention and Protocol help to reduce legal uncertainty caused by differences in national laws and thereby open up to developing countries access to finance at reasonable cost. Sir Roy Goode, who had been Chairman of the UNIDROIT Study Group that initiated the project, has prepared the commentary on the Convention, which was published by UNIDROIT and is now distributed by Hart Publishing, Oxford. This revised edition provides a detailed analysis of the two instruments. Major developments that have occurred since the publication of the first edition include the entry into force of the Convention and Aircraft Protocol, nearly 100,000 registrations in the International Registry, and the experience of practitioners handling thousands of transactions relating to the two instruments. This is an invaluable work of reference and indispensable guide for practitioners and all those who enter into transactions governed wholly or partially by the Convention.
