-65. Regrettably, the response of the Greek authorities to the report on the 2009 visit did not allay the concerns of the Committee. Once again, too many of the CPT’s recommendations were left either unanswered or the responses did not address the fundamental concerns raised in the report. The Committee considered that it was important to undertake a further visit to examine whether any progress had been made towards implementing its recommendations before considering what action to take in respect of the pending Article 10, paragraph 2, procedure2. C. Cooperation between the CPT and the Greek authorities 6. A list of the persons met by the CPT’s delegation in the course of the visit can be found in Appendix III of the report. 7. The CPT’s 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 of the visit by the liaison officers from the Ministries of Citizen’s Protection, Foreign Affairs and Justice. Thus, as regards the facilitation of the visit by the Greek authorities, the cooperation can be considered as being on the whole very good. However, the CPT’s delegation found that long-standing recommendations in key areas covered by the Committee’s preventive mandate had still not been implemented. Further, even where the Greek authorities had responded to previous visit reports that action had been taken, it turned out that the information provided did not correspond to the reality observed on the ground. The CPT has repeatedly emphasised that the principle of cooperation set out in the Convention requires that decisive action be taken to improve the situation in the light of the Committee’s recommendations. Further, for a meaningful ongoing dialogue to be conducted it is self-evident that the information provided in a State’s response must be accurate and reliable. 8. It is regrettable that the Greek authorities have not engaged themselves in a full and frank dialogue with the CPT nor taken significant steps to address the recommendations put forward by the Committee, in particular as regards the conditions of detention of irregular migrants and the situation in the prisons. The lack of action taken by the authorities to tackle the systemic deficiencies identified by the Committee in these areas was evident to the delegation which carried out the visit in January 2011. The CPT finds it not only necessary to reiterate many recommendations but even to recall to the Greek authorities that it is imperative for the Committee to be provided with complete and accurate information in relation to the various issues raised in its reports. Responses to the CPT’s reports represent a key component of a dialogue designed to identify and remedy any shortcomings in a State’s fulfilment of its obligation to prevent torture and inhuman or degrading treatment or punishment. If the information provided to the Committee is unreliable there can be no basis for cooperation. The CPT trusts that the Greek authorities will provide a full and reliable response to this visit report, detailing the concrete action taken to address the various recommendations put forward by the Committee. 2 On 15 March 2011, the CPT made a public statement concerning Greece.
