This is the ninth edition of Professor Valentine Korah"s widely respected book on EC competition law and practice, which, for many years, has been used by practicing lawyers and law students, as well as officials. The book has kept pace with the rapid development of the subject. Its description of economic theory and the policy considerations which underpin the law — and its enforcement — are even more important in the era of modernization, when the enforcement of competition law has become decentralized to the Member States. The book"s analysis and trenchant comment on the legislation, case law, and policies have had some influence on the development of the law, a fact acknowledged by many experts in the subject. Despite the complexity of the topic, this remains a lucid and readable overview which is ideal for newcomers to the subject.
