This book provides invaluable insights to one of the most difficult areas of European integration. Public procurement represents an instrument of policy choice for governments and its regulation interacts with a variety of policies, including the promotion of competition, employment, social policy, and environmental protection. The author vividly elaborates on the in-built flexibility of the newly enacted rules and provides a codified analysis of their interpretation by the EU judiciary. Finally, considerable debate is dedicated to future dimensions of public procurement regulation in the form of public private partnerships and concessions.
