-75. With a few exceptions, the cooperation received during the visit by the CPT’s delegation from the Greek central authorities, as well as from the management and staff in the establishments visited, was very good. The delegation enjoyed rapid access to all the places of detention it wished to visit, was able to interview in private persons deprived of their liberty and was provided with the information it needed to accomplish its task. The CPT wishes to express its appreciation for the assistance provided to its delegation in the course of the visit by the liaison officers from the Ministries of Foreign Affairs, Citizens’ Protection, and Health. 6. Regretfully, however, the central authorities provided the delegation only at a very late stage with the credentials and information requested concerning establishments falling under the responsibility of the Ministry of Health. Further, the management at Dromokaiteio Hospital was only informed of the delegation’s visit less than one hour before its arrival, despite the fact that the visit to that particular establishment – as well as a list of requests for information to be provided to the delegation – had been notified to the Greek authorities some ten days before the visit began. As a result, the smooth operation of the visit was somewhat hampered. Moreover, at the local level, information provided by the duty senior officer at Isaakio Police Station proved to be clearly misleading. For example, the register consulted by the delegation indicated that foreign nationals had regularly been held at the police station overnight in the weeks and months prior to the visit, a fact that had initially been denied by the duty senior officer. Further, on the occasion of its first visit to the establishment, the delegation had been given an assurance by the duty senior officer that the filthy detention area would be immediately cleaned up. However, during a follow-up visit to the facility two days later, the detention area had still not been cleaned and yet was holding 41 persons. 7. The principle of cooperation encompasses the obligation of the national authorities to provide documents and information requested by the CPT in a timely and accurate manner. At the very least, those establishments in respect of which the Committee has requested specific information in its notification letter should be informed about the imminent arrival of a CPT delegation. Effective and efficient coordination and communication among the ministries concerned in the preparation and follow-up of the CPT’s visits are essential elements of this cooperation. This also includes the need to ensure that the Government responses to the CPT’s visit reports do indeed address all of the recommendations and information requests made by the Committee. The CPT trusts that the Greek authorities will take the necessary steps to ensure that, in future, visiting delegations are provided in good time with credentials and with accurate information allowing them to accomplish their task. All establishments indicated in the notification of the visit should be made aware of the CPT’s visit in a timely manner. Further, the Committee urges the Greek authorities to ensure effective and efficient coordination among the ministries concerned in the preparation of and follow-up to CPT visits. 8. Moreover, the CPT has repeatedly stressed that the principle of cooperation as set out in Article 3 of the Convention is not limited to facilitating the work of visiting delegations, but also requires that decisive action is taken to effectively implement the recommendations made by the Committee.
