This reference work examines the procedure and practice relating to commercial agreements and trade association practices under UK and EC competition laws. It first covers procedure in both the UK and EC, and then provides a detailed comparative analysis of all the major types of commercial agreements and trade association practices in both UK and EC law. Since much of competition law is, in practice, administered by administrative rather than judicial bodies, full treatment is given to the informal administrative solutions applied by the authorities. However, as an increasing amount of competition law is subject to litigation, there is also in-depth analysis of all the major cases. There is also a full discussion of the EC block exemptions and recent developments in UK competition law.
