Article 23 10.

Where authorisation referred to in paragraph 9 of this Article is applied for, the national judicial authority shall verify 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 the proportionality of the coercive measures, the national judicial authority may ask the Commission, directly or through the national competent authority of the Member State, enforcing the rules referred to in Article 1(6), for detailed explanations in particular on the grounds the Commission has for suspecting infringement of this Regulation, as well as on the seriousness of the suspected infringement and on the nature of the involvement of the undertaking concerned. However, the national judicial authority may not call into question the necessity of the inspection nor demand that it be provided with the information in the file of the Commission. The lawfulness of the Commission decision shall be subject to review only by the Court of Justice.
