CAT/C/DEU/CO/6 (c) The conditions of detention of individuals suspected of terrorism are in accordance with the requirements set out in article 5 of the Convention for the Protection of Human Rights and Fundamental Freedoms and the Nelson Mandela Rules; (d) Individuals suspected of terrorism who are in detention, including in the context of deportations, have adequate access to legal representation and effective complaint mechanisms. The State party should also collect and publish statistical data on the number, nature and outcome of the complaints filed by those detainees; (e) Surveillance activities are carried out in accordance with its obligations under the Convention, and that any interference with human rights are in line with the principles of legality, necessity and proportionality. 46. The State party should provide information on the concrete steps taken to investigate the alleged involvement of its law enforcement officers in rendition and secret detention programmes. 47. The State party should refrain from facilitating operations from or through its territory that constitute a gross violation of the absolute prohibition against torture under the Convention. Trafficking in human beings 48. The Committee welcomes the important steps taken by the State party to develop the legal and institutional framework for combating trafficking in human beings, noting the importance of this matter and the continued evaluation of the State party by the Group of Experts on Action against Trafficking in Human Beings (arts. 2, 12 and 16). 49. The State party should take all measures to prevent and combat trafficking in human beings, especially children, including by implementing the recommendations contained in the reports by the Group of Experts on Action against Trafficking in Human Beings. The State party should ensure that violations are investigated, and perpetrators are prosecuted and, if convicted, punished with appropriate sanctions. Reparations and redress 50. The Committee is concerned that victims of torture, in particular asylum seekers and undocumented migrants, lack sufficient resources to access comprehensive services for rehabilitation, and that the overwhelming majority of psychosocial and therapeutic services are provided by civil society instead of social assistance or health-care providers (art. 14). In this regard, the Committee draws the State party’s attention to its general comment No. 3 (2012) on the implementation of article 14. 51. The State party should ensure in law that victims of torture or ill-treatment, whether committed within the State party or abroad, obtain full and effective redress and reparation, including compensation and the means for as full a rehabilitation as possible. The State party should also provide the Committee with information on legislative measures to ensure funding is available in all Länder for rehabilitative services, including specialized treatment, for victims of torture and ill-treatment. Training and education 52. The Committee is concerned at the insufficient attention to the Convention in the training of military personnel, as well as the apparent absence of an introduction to international humanitarian law and international human rights law, including the Convention, in the curricula of the German Armed Forces United Nations Training Centre. 53. While taking positive note that the Istanbul Protocol is widely disseminated and part of the training provided to employees of the Federal Office for Migration and Refugees, the Committee regrets the lack of information on training at the level of the Länder, in particular training for medical professionals working with asylum seekers and undocumented migrants. 9
