1. Member States shall be responsible for checking compliance with the obligations imposed on carriers by Articles 5 (2), 6 and 11 of this Regulation and with the obligation to supply information as laid down in Article 13. They shall introduce the necessary measures for this purpose before 1 July 1961, after consulting the Commission. 2. In so far as may be necessary in order to implement this Regulation, the Commission may send its officials or any experts on visits of inspection to check and supervise compliance with the obligations imposed on undertakings by Articles 5, 6, 11 and 13 of this Regulation. To this end, any authorised representatives of the Commission shall have the following rights and powers: (a) to check the books and other business records of undertakings; (b) to take copies or extracts of such books and records on the spot; (c) to be given access to all premises, land and vehicles of undertakings; (d) to require explanations on all points relating to the books and records of undertakings. Authorised representatives of the Commission shall exercise these rights on production of a pass stating that they are empowered to carry out all necessary inspections pursuant to this Article. They must carry a written authority naming the undertaking to be inspected and the purpose of the inspection. Details of the written authority and of the status of the persons responsible for carrying out the inspection shall be duly notified beforehand to the Member State concerned. Officials of that State may, at the request either of the latter or of the Commission, assist the authorised representatives of the Commission in the performance of their duties. If any undertaking refuses inspection as provided for in this Regulation, the Member State concerned shall give the authorised representatives of the Commission such support and assistance as may be necessary for the purpose of carrying out their inspections as instructed. Member States shall introduce the necessary measures for this purpose before 1 July 1961, after consulting the Commission. 3. All persons taking part in inspections as provided for in this Article shall observe professional secrecy, in accordance with Article 214 of the Treaty.
