1. Where an intended measure covered by Article 32(3) aims to impose, amend or withdraw an obligation on an undertaking in application of Article 61 or 67 in conjunction with Articles 69 to 76 and Article 83, the Commission may, within the one-month period referred to in Article 32(3), notify the national regulatory authority concerned and BEREC of its reasons for considering that the draft measure would create a barrier to the internal market or of its serious doubts as to its compatibility with Union law. In such a case, the draft measure shall not be adopted for a further three months following the Commission's notification.

In the absence of such notification, the national regulatory authority concerned may adopt the draft measure, taking utmost account of any comments made by the Commission, BEREC or any other national regulatory authority.

2. Within the three-month period referred to in paragraph 1 of this Article, the Commission, BEREC and the national regulatory authority concerned shall cooperate closely to identify the most appropriate and effective measure in light of the objectives laid down in Article 3, whilst taking due account of the views of market participants and the need to ensure the development of consistent regulatory practice.
