Commission departments responsible for organising meetings at which information classified CONFIDENTIEL UE/EU CONFIDENTIAL or above is discussed shall, through their LSO or through the meeting organiser, inform the Commission Security Authority well in advance of the dates, times, venue and participants of such meetings.

Subject to the provisions of Article 11(13), individuals assigned to participate in meetings organised by the Commission at which information classified CONFIDENTIEL UE/EU CONFIDENTIAL or above is discussed, may only do so upon confirmation of their security clearance or security authorisation status. Access to such classified meetings shall be denied to individuals for whom the Commission Security Authority has not seen a PSCC or other proof of security clearance, or, to participants of the Commission who are not in possession of a security authorisation.

Before organising a classified meeting, the responsible meeting organiser or the LSO of the Commission department organising the meeting, shall request external participants to provide the Commission Security Authority a PSCC or other proof of security clearance. The Commission Security Authority shall inform the LSO or the meeting organiser of PSCC or other proof of PSC received. Where applicable, a consolidated list of names may be used, giving the relevant proof of security clearance.

Where the Commission Security Authority is informed by the competent authorities that a PSC has been withdrawn from an individual whose duties require attendance at meetings organised by the Commission, the Commission Security Authority shall notify the LSO of the Commission department responsible for organising the meeting.
