This contribution discusses the preliminary ruling in Coty (C-230/16) in which the European Court of Justice addresses competition law ambiguities pertaining to selective distribution, in particular with respect to the use of third-party online platforms as a distribution channel.

This contribution analyses the ruling and discusses selective distribution, preserving a luxury or prestigious product image, and vertical agreements in the context of e-commerce.
