- 11 A list of the national authorities and organisations met by the delegation is set out in Appendix II to this report. 6. 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, with a few exceptions, very good. The delegation had rapid access to the places of detention visited, was able to speak in private with those persons with whom it wanted to meet and was provided with access to the information it required to carry out its task. The CPT wishes to express its appreciation for the assistance provided to its delegation in the course the visit by the liaison officers from the Ministries of Foreign Affairs, Justice and the Interior and Administrative Reconstruction (hereafter “Ministry of the Interior”). 7. As regards the few exceptions, it was regrettable that on two occasions (18 and 23 April) law enforcement officials working on the 11th and 12th floors of the Hellenic Police Headquarters at Alexander Street (GADA) in Athens attempted to mislead the CPT’s delegation and impede it from gaining access to 15 small holding cells. On the first occasion, it took more than one hour to gain access to the detention area, which was concealed and labelled as a toilet (“WC”). The delegation also came across a specific request made by the Prison Board of Nafplio Prison concerning the transfer of 69 prisoners “in view of the CPT’s planned visit to our prison”. The transfer was approved by the Ministry of Justice and supervisory prosecutor. The prisoners identified for transfer were, according to the Director of the Prison, the most problematic, with long sentences and generally considered a threat to the good order of the prison. Consequently, in the week prior to the delegation’s visit to this establishment, 29 prisoners from that list left the prison. The CPT considers that the main reason for the precipitous transfer of these prisoners was to mislead its delegation or conceal the real situation at Nafplio Prison from it. The CPT trusts that the Greek authorities will take the necessary steps to ensure that in future no attempts will be made to impede access to detention facilities or mask the real situation by transferring detained persons out of an establishment due to the Committee having notified in advance of its intention to visit that particular establishment. 8. Reference should also be made to the initial impediments put forward by the Athens Public Prosecutor’s Office in enabling the delegation to consult and take notes on specific files relating to the investigation of allegations of ill-treatment by police officers. However, once the scope of the Committee’s mandate under Article 8 of the Convention was clearly explained, access was granted to the files and cooperation improved. Examining the effectiveness of investigations into allegations of ill-treatment of persons deprived of their liberty is an important aspect of the Committee’s work and it is necessary for prosecutors and judges to be fully aware of the CPT’s mandate and of their duty to cooperate with the Committee. The CPT trusts that the Greek authorities will ensure – through the appropriate channels – that prosecutors and judges fully understand the Committee’s mandate and their duty to cooperate with the CPT.
