Each Member State and Europol may entrust with the processing of data at Europol, only those persons who have had special training and undergone security screening.

The whole security-screening process together with the results obtained shall be subject to the relevant rules and regulations in force in the Member State concerned, including those concerning appeals.

The Head of the Commission Security Office shall specify in its request the type and level of classified information to be made available to the person concerned, so that the competent national authorities can carry out the screening process and give their opinion as to the level of authorisation it would be appropriate to grant to that person.
