Recital 143

It is also necessary for competent authorities to have, in accordance with national law and with the Charter, the ability to access the premises of natural and legal persons. Access to such premises is necessary when there is reasonable suspicion that documents and other data relating to the subject matter of an investigation exist and may be relevant to prove an infringement of this Directive or of Regulation (EU) No 600/2014. Additionally, access to such premises is necessary where the person to whom a demand for information has already been made, fails to comply with such demand wholly or in part; or where there are reasonable grounds for believing that if a demand were to be made, it would not be complied with, or that the documents or information to which the information requirement relates, would be removed, tampered with or destroyed. If prior authorisation is needed from the judicial authority of the Member State concerned, in accordance with national law, such power for access into premises should be used after having obtained that prior judicial authorisation.
