This collection, edited by Catharine Barnard and Joanne Scott, brings together a strong team of European lawyers seeking to unpack some of the core legal concepts underpinning the Single European Market. All in all, this edited collection is of a generally high calibre and deserves to be widely read... this collection contributes to many of the current debates on the single European market and brings to the fore the imprecision that still surrounds many of its core concepts.
