On 20 June 2013, the European Commission has launched a Public Consultation in order to revise the Council Regulation (EC) No 139/2004 of the 20 January 2004 on the control of concentrations between undertakings. In its Working document the Commission essentially proposes two modifications: (i) the extension of the field of merger control to the acquisition of non-controlling minority stakes and (ii) the improvement of the transfer procedure of cases between the Commission and national competition authorities. The Commission invites interested third parties to submit their comments on 12 September 2013 at the latest.
