A/HRC/13/31 detention and the treatment of the detainees. There was also no information about the procedures in place to decide about their detention and its duration. This practice is believed to amount to enforced disappearance and to involve other serious human rights violations, including torture or other ill-treatment. 537. The role of the Government in this practice allegedly includes the detention of persons inside its territory and their extrajudicial transfer to the custody of foreign intelligence agencies. 538. There were also reports that the Government of Sweden was allegedly informed by the secret detention of a number of persons falling under its jurisdiction or protection and provided no information of their fate or whereabouts to their respective families. The Government did not seek to facilitate their return. Reply from the Government 539. On 8 July 2009, the Government replied to the general allegation stating that it noted that the Working Group made general reference to information received from sources without any further specification concerning the nature of these sources. Unfortunately, based on the general and unspecified information provided by the Working Group, the Government is not in a position to provide substantive answers to the questions posed by the Working Group. 540. With the view to investigate earlier allegations put forward in Swedish media regarding the Government’s involvement in renditions, the Government instructed the Swedish Civil Aviation Authority and the LFV Group (Swedish Airports and Air Navigation Services) to carry out an investigation into the exact circumstances of all flights made by aircrafts suspected of being allegedly used to carry out renditions between 1 January 2002 and 17 November 2005. The results of the investigations have been presented in two reports of 7 December 2005 and 15 December 2005 and included more than 19,000 flights, both arrivals and departures. The finding of the reports is that it cannot be concluded that any of these flights were connected to the alleged practice of rendition. These reports have inter alia been submitted to the Secretary General of the Council of Europe. Finally, the Government assures that no enforced disappearances have been sanctioned by the Government of Sweden or Swedish authorities. Observations 541. The Working Group notes that the Government has signed the International Convention for the Protection of All Persons from Enforced Disappearance and calls upon the Government to ratify it and accept the competence of the Committee under articles 31 and 32.
