In this second issue of CLPD in 2017 we take a closer look at the long-awaited Preliminary Report on the European Commission’s E-commerce Sector Inquiry (“Preliminary Report”). We also take into account the findings of the Final Report on the European Commission’s E-commerce Sector Inquiry (“Final Report”), which was published on 10 May 2017, i.e. only a few days before the publication on this issue. The Final Report to a large extent repeats and confirms the findings of the Preliminary Report. The goal of the e-Commerce Sector Inquiry, as the Commission explains in the Preliminary Report, was to obtain an overview of the prevailing market trends and gather evidence on potential barriers to competition linked to the growth of e-commerce. In addition, through the Sector Inquiry, the Commission was seeking to understand to what extent the growth of e-commerce has led to an increase in contractual restrictions that could raise antitrust concern.
