1. In order to carry out its duties under this Regulation, ESMA may conduct all necessary on-site inspections at the business premises of the legal persons referred to in Article 23b(1). Where the proper conduct and efficiency of the inspection so require, ESMA may carry out the on-site inspection without prior announcement.
2. The officials of and other persons authorised by ESMA to conduct an on-site inspection may enter any business premises and land of the legal persons subject to an investigation decision adopted by ESMA and shall have all the powers stipulated in Article 23c(1). They shall also have the power to seal any business premises and books or records for the period of, and to the extent necessary for, the inspection.
3. The officials of and other persons authorised by ESMA to conduct an on-site inspection shall exercise their powers upon production of a written authorisation specifying the subject matter and purpose of the inspection, and the periodic penalty payments provided for in Article 36b where the persons concerned do not submit to the inspection. In good time before the inspection, ESMA shall give notice of the inspection to the competent authority of the Member State where it is to be conducted.
4. The persons referred to in Article 23b(1) shall submit to on-site inspections ordered by decision of ESMA. The decision shall specify the subject matter and purpose of the inspection, specify the date on which it is to begin and indicate the periodic penalty payments provided for in Article 36b, the legal remedies available under Regulation (EU) No 1095/2010 as well as the right to have the decision reviewed by the Court of Justice of the European Union. ESMA shall take such decisions after consulting the competent authority of the Member State where the inspection is to be conducted.
5. Officials of, as well as those authorised or appointed by, the competent authority of the Member State where the inspection is to be conducted shall, upon the request of ESMA, actively assist the officials of and other persons authorised by ESMA. To that end, they shall enjoy the powers set out in paragraph 2. Officials of the competent authority of the Member State concerned may also attend the on-site inspections upon request.
6. ESMA may also require competent authorities to carry out specific investigatory tasks and on-site inspections as provided for in this Article and in Article 23c(1) on its behalf. To that end, competent authorities shall enjoy the same powers as ESMA as set out in this Article and in Article 23c(1).
7. Where the officials of and other accompanying persons authorised by ESMA find that a person opposes an inspection ordered pursuant to this Article, the competent authority of 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 on-site inspection.
8. If the on-site inspection provided for in paragraph 1 or the assistance provided for in paragraph 7 requires authorisation by a judicial authority according to national rules, such authorisation shall be applied for. Such authorisation may also be applied for as a precautionary measure.
9. Where authorisation as referred to in paragraph 8 is applied for, the national judicial authority shall control that the decision of ESMA 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 the proportionality of the coercive measures, the national judicial authority may ask ESMA for detailed explanations, in particular relating to the grounds ESMA has for suspecting that an infringement of this Regulation has taken place and the seriousness of the suspected infringement and the nature of the involvement of the person subject to the coercive measures. However, the national judicial authority shall not review the necessity for the inspection or demand to be provided with the information on ESMA's file. The lawfulness of ESMA's decision shall be subject to review only by the Court of Justice of the European Union following the procedure set out in Regulation (EU) No 1095/2010.
