Article 48d
On-site inspections
Where a national judicial authority receives an application for the authorisation of an on-site inspection provided for in paragraph 1 or the assistance provided for in paragraph 7, that authority shall verify the following:
the decision adopted by ESMA referred to in paragraph 5 is authentic;
any measures to be taken are proportionate and not arbitrary or excessive.
For the purposes of point (b), 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 of the investigation or demand that it 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 following the procedure set out in Article 61 Regulation (EU) No 1095/2010.
