Chapter 9 traces the evolution of the internal market and sets it against the worldviews and economic ideologies dominating throughout the 1980s and 1990s. It argues that subsequently a specific permissive consensus towards market liberalisation has been gradually replaced by a constraining dissensus. During the 2000s this shift was recognisable in how national governments approached some of the boldest internal market case-law of the Court of Justice. More recently also the Commission and the Luxembourg court have visibly changed their approaches towards the internal market. The Commission visibly manifests this attitude in its stance on posting of workers. The Court of Justice, on the other hand, has followed an ultimately similar position in its decisions defining the boundaries of the so-called collaborative economy. The chapter explains that this “rollback” of the internal market is partly due to the setup in which serious economic divergences prevail, and partly due to flaws in other European policies.
