Competent authorities shall coordinate their market surveillance and enforcement activities. They shall exchange all information necessary to achieve this.

When competent authorities become aware that an intra-Community infringement harms the interests of consumers in more than two Member States, the competent authorities concerned shall coordinate their enforcement actions and requests for mutual assistance via the single liaison office. In particular they shall seek to conduct simultaneous investigations and enforcement measures.

The competent authorities shall inform the Commission in advance of this coordination and may invite the officials and other accompanying persons authorised by the Commission to participate.

The measures necessary for the implementation of this Article shall be adopted in accordance with the procedure referred to in Article 19(2).
