Article 20 Carriage of RESTREINT UE/EU RESTRICTED documents within Commission buildings
United Kingdom
1.
Staff may carry RESTREINT UE/EU RESTRICTED documents within a Commission building, but the documents shall not leave the possession of the bearer or be read in public.
2.
RESTREINT UE/EU RESTRICTED documents may be sent through internal mail to other European Commission offices in a single ordinary opaque envelope, but with no indication on the outside that the contents are classified. Other EU institutions or bodies served directly by the Commission's internal mail system may also be sent RESTREINT UE/EU RESTRICTED documents in the same way.
