Shearman & Sterling Responds to the EC Market Definition Notice Consultation

In her first speech upon being reappointed as Competition Commissioner, Commissioner Vestager announced that a review would be undertaken of the Commission’s Market Definition Notice (the “Notice”); the consultation on that review closed Friday,  October 9th. The Notice is an important document in European competition law; it sets out the analytical framework under which the Commission decides who competes with who, a process which has determinative implications in both merger control and antitrust enforcement. The Notice is however older than most law firm trainees and clearly showing its age. Revising the Notice now can act as a release valve in response to calls for radical reforms to the merger review process in the wake of its controversial Siemen / Alstom prohibition, without regulation or treaty change, which could open a pandora’s box for the Commission. The consultation also needs to be considered in the context of a plethora of other reform initiatives to EU competition law aimed at harnessing U.S. tech giants.
