Public Services in EU Law [PDF ebook] 

In the EU public services, utilities and welfare services can be seen as both building blocks for the internal market and as a persistent irritant in the integration process. This book provides a comprehensive overview of the EU law on public services within the context of European integration. It brings together important analysis of the primary Treaty law, mainly on the internal market and competition, and of the secondary legislation at EU level, including different sector specific regimes. Particular attention is given to case law of the EU courts. This will be essential reading for those looking to have a broader understanding of the subject.
