498It must be noted that the aim of Article 4(1) and of Article 7(1) of Regulation No 139/2004 is to ensure the effectiveness of the system of ex ante control of the effects of concentrations with a Community dimension (see, to that effect and by analogy, judgment of 12 December 2012, Electrabel v Commission, T‑332/09, EU:T:2012:672, paragraph 246). It should also be noted that the objective of the EU rules on the control of concentrations is the prevention of irreparable and permanent damage to competition (judgment of 12 December 2012, Electrabel v Commission, T‑332/09, EU:T:2012:672, paragraph 245). The system for the control of concentrations is intended to enable the Commission to exercise ‘effective control of all concentrations in terms of their effect on the structure of competition’ (recital 6 of Regulation No 139/2004).
