This book achieves its purpose in accurately describing the impact that EU law has had on the UK legal order. Although, as the author himself acknowledges, it can not stand as a comprehensive account of EU law it is a great introduction to the field and an essential reference book for every practitioner in the UK.

Vasselos Frakos, The JUSTICE Journal

For practitioners, the broad scope of the book will be invaluable...The real value of the book lies in its coverage of the UK perspective to the relevant EU provisions.

Malcolm Jarvis, European Law Review, Volume 37(5)

Aidan O'Neill has written a comprehensive and substantial work giving an overall view of the application of European Union law at the national level and clearly aimed at the busy UK legal professional who needs an accessible and authoritative reference close to hand.

The book benefits considerably from Mr O'Neill's experience as a practitioner in both Scotland and England, not only with references to Scots case law in this area where appropriate, but also in his feel for some of the civil law concepts used by the European courts when interpreting and applying European law in specific areas.

Litigation practitioners in particular will find Mr O'Neill's analysis of the application of this overarching, principles based, case law at both European and UK level helpful in predicting how a court should approach an EU law question and what the likely range of possible outcomes for their clients might be.
The approach to each subject area is a practical one with a focus on the enforcement of EU law by EU and national authorities and the supervision of their activities and remedies available through the courts. Again, the background to the case law is given where relevant, so that the reader can fully understand the way in which EU law principles can be used.

This is a welcome addition to the practitioners' library and will also help give those with a more specialist view of EU law – competition lawyers for example – a helpful broader perspective over the general principles which apply equally in other fields of EU law.

Vincent Smith, Law Society Gazette

The author takes each discipline as a standalone chapter, but taken as a whole, demonstrates the full and daily impact of EU law. He does so with authority, lucidly describing the treaty base before moving to consider secondary EU legal instruments such as directives, concluding with implementation in the UK...This is a compelling text and at this price is worthy of being in all practices.

David J Dickinson, Journal of the Law Society of Scotland

... O'Neil's epic journey through both well-travelled areas and dark corners of EU law is successful in its purpose: to provide the reader with the most authoritative reference book on EU law.

... O'Neil does well in establishing a niche in the market as the author of the most comprehensive English guide to EU law [which will be] a welcome addition to any law library
