A/HRC/22/52 States that have so far failed to provide substantive responses to the inquiries made by the joint mandate-holders to do so without further delay. 45. In March 2009, the United States Senate Select Committee on Intelligence began a comprehensive investigation into the CIA's secret detention and interrogation programme, chaired by Senator Dianne Feinstein. The Special Rapporteur commends the United States for establishing an independent parliamentary which has reportedly had unrestricted access to classified information. On 1 December 2011, Senator Feinstein announced that the Committee was close to the completion of the comprehensive review, and the report was approved by the Committee the same month.106 46. The Special Rapporteur calls on the United States to release the full Senate Select Committee report as soon as possible, subject only to the specific redaction of such particulars as are considered by the Select Committee itself to be strictly necessary to safeguard legitimate national security interests or the physical safety of persons identified in the report. 47. On 6 July 2010, the Prime Minister of the United Kingdom announced an independent inquiry by members of the Privy Council (a body made up mainly of senior serving or retired politicians of distinction and senior judges), under the Chairmanship of Sir Peter Gibson, a retired judge with experience on national security issues. The Gibson Inquiry was set up in order to consider whether, and to what extent, the United Kingdom Government and its security and intelligence agencies were involved in, or aware of, the improper treatment or rendition of detainees held by other countries in counter terrorism operations outside the United Kingdom. 48. The terms of reference for the Gibson Inquiry were published on 6 July 2011 and a protocol was subsequently issued which governed its procedures. The inquiry lacked the power to compel the attendance of witnesses or the production of documents. Nor did it have any power to request the production of evidence from other States, or their personnel. Moreover, under the protocol established for the inquiry, the final decision as to whether any document or finding could be released to the public was vested in the Cabinet Secretary (a senior civil servant). As a result, the detainees, their lawyers and the NGOs who were supporting them, withdrew their cooperation.107 Thereafter, the Special Rapporteur, acting together with the Special Rapporteur on torture, engaged the United Kingdom in correspondence about the powers, terms of reference and protocol for the Gibson Inquiry.108 On 18 January 2012, the Justice Secretary announced there was no prospect of the Gibson Inquiry being able to start in the foreseeable future and the Government had therefore decided to terminate it. He indicated, however, that the inquiry would provide an interim report, which was delivered to the Prime Minister on 27 June 2012. Despite Government assurances of transparency, the interim report has not so far published and the Government has given no public explanation for the delay. 49. The Special Rapporteur calls upon the United Kingdom to publish the interim report of the Gibson Inquiry without further delay, subject only to such redactions as are considered by the independent inquiry team itself to be strictly necessary to safeguard legitimate national security interests or the physical safety of persons identified in the 106 107 108 18 S8130, Congressional Report – Senate, 1 December 2011, p. 52.
