This Regulation alone shall apply to concentrations as defined in Article 3, and Council Regulations (EC) No 1/2003(8), (EEC) No 1017/68(9), (EEC) No 4056/86(10) and (EEC) No 3975/87(11) shall not apply, except in relation to joint ventures that do not have a Community dimension and which have as their object or effect the coordination of the competitive behaviour of undertakings that remain independent.

2. Subject to review by the Court of Justice, the Commission shall have sole jurisdiction to take the decisions provided for in this Regulation.

3. No Member State shall apply its national legislation on competition to any concentration that has a Community dimension.

The first subparagraph shall be without prejudice to any Member State's power to carry out any enquiries necessary for the application of Articles 4(4), 9(2) or after referral, pursuant to Article 9(3), first subparagraph, indent (b), or Article 9(5), to take the measures strictly necessary for the application of Article 9(8).

4. Notwithstanding paragraphs 2 and 3, Member States may take appropriate measures to protect legitimate interests other than those taken into consideration by this Regulation and compatible with the general principles and other provisions of Community law.

Public security, plurality of the media and prudential rules shall be regarded as legitimate interests within the meaning of the first subparagraph.

Any other public interest must be communicated to the Commission by the Member State concerned and shall be recognised by the Commission after an assessment of its compatibility with the general principles and other provisions of Community law before the measures referred to above may be taken. The Commission shall inform the Member State concerned of its decision within 25 working days of that communication.
