This book has attempted to, in effect, go right back to where it all began and examine the case law on free movement in a genealogical sense to expose fissures: latent defects in the project that appear to have come to light fifty years later. Prior to Brexit, such latent defects were never even thought of as such, with the emphasis being, if anything, upon closer integration at all costs. Chapters 1 and 2 outlined a specific way in which the worker was outlined in a (then) Community context, leading to a further set of legal developments in how to conceptualize and legally protect those that did not count as workers.
