Article 13 — The Commission's powers of inspection

1. In order to carry out the duties assigned to it by this Regulation, the Commission may conduct all necessary inspections of undertakings and associations of undertakings.
2. The officials and other accompanying persons authorised by the Commission to conduct an inspection shall have the power:
   1. to enter any premises, land and means of transport of undertakings and associations of undertakings;
   2. to examine the books and other records related to the business, irrespective of the medium on which they are stored;
   3. to take or obtain in any form copies of or extracts from such books or records;
   4. to seal any business premises and books or records for the period and to the extent necessary for the inspection;
   5. to ask any representative or member of staff of the undertaking or association of undertakings for explanations on facts or documents relating to the subject matter and purpose of the inspection and to record the answers.
3. Officials and other accompanying persons authorised by the Commission to conduct an inspection shall exercise their powers upon production of a written authorisation specifying the subject matter and purpose of the inspection and the penalties provided for in Article 14, in the production of the required books or other records related to the business which is incomplete or where answers to questions asked under paragraph 2 of this Article are incorrect or misleading. In good time before the inspection, the Commission shall give notice of the inspection to the competent authority of the Member State in whose territory the inspection is to be conducted.
4. Undertakings and associations of undertakings are required to submit to inspections ordered by decision of the Commission. The decision shall specify the subject matter and purpose of the inspection, appoint the date on which it is to begin and indicate the penalties provided for in Articles 14 and 15 and the right to have the decision reviewed by the Court of Justice. The Commission shall take such decisions after consulting the competent authority of the Member State in whose territory the inspection is to be conducted.
5. Officials of, and those authorised or appointed by, the competent authority of the Member State in whose territory the inspection is to be conducted shall, at the request of that authority or of the Commission, actively assist the officials and other accompanying persons authorised by the Commission. To this end, they shall enjoy the powers specified in paragraph 2.
6. Where the officials and other accompanying persons authorised by the Commission find that an undertaking opposes an inspection, including the sealing of business premises, books or records, ordered pursuant to this Article, the Member State concerned shall afford them the necessary assistance, requesting where appropriate the assistance of the police or of an equivalent enforcement authority, so as to enable them to conduct their inspection.
7. If the assistance provided for in paragraph 6 requires authorisation from a judicial authority according to national rules, such authorisation shall be applied for. Such authorisation may also be applied for as a precautionary measure.
8. Where authorisation as referred to in paragraph 7 is applied for, the national judicial authority shall ensure that the Commission decision is authentic and that the coercive measures envisaged are neither arbitrary nor excessive having regard to the subject matter of the inspection. In its control of proportionality of the coercive measures, the national judicial authority may ask the Commission, directly or through the competent authority of that Member State, for detailed explanations relating to the subject matter of the inspection. However, the national judicial authority may not call into question the necessity for the inspection nor demand that it be provided with the information in the Commission's file. The lawfulness of the Commission's decision shall be subject to review only by the Court of Justice.
