A/HRC/WGAD/2013/36 told the reasons for their detention or whether they will ever be released and no information regarding their whereabouts is provided to friends, neighbours, co-workers or more distant relatives who enquire about them (Ibid.). 31. The Working Group recalls that on 3 October 2012, together with the Special Rapporteur on the situation of human rights in the Democratic People’s Republic of Korea, the Special Rapporteur on extrajudicial, summary or arbitrary executions, the Special Rapporteur on torture and other cruel, inhuman or degrading treatment or punishment and the Working Group on Enforced or Involuntary Disappearances, it sent a joint letter to the Government of the Democratic People’s Republic of Korea on the alleged use of labour camps for political prisoners. Having received no response from the Government, the mandate holders issued a press release in February 2013 calling for an international inquiry into the human rights abuses in the Democratic People’s Republic of Korea, which would shed light on the country’s extensive political prison camp system. 32. The Working Group takes note of the recently established Commission of Inquiry on human rights in the Democratic People’s Republic of Korea that was mandated by the Human Rights Council in resolution 22/13 to investigate the systematic, widespread and grave reports of violations of human rights in the Democratic People’s Republic of Korea, with a view to ensuring full accountability, in particular for violations which could amount to crimes against humanity. Among the violations to be investigated are those pertaining to the right to food, those associated with prison camps, torture and inhuman treatment, arbitrary detention, discrimination, freedom of expression, the right to life, freedom of movement and enforced disappearances, including in the form of abductions of nationals of other States. 33. In a statement made to the sixty-eighth session of the Third Committee of the General Assembly on 29 October 2013, the Chair of the Committee noted that the final conclusions and recommendations of the Commission of Inquiry would have to await the end of the investigation, but that the entire body of evidence gathered to date pointed to what appeared to be large-scale patterns of systematic and gross human rights violations. 34. The Working Group recalls that it noted in its Opinions No. 4/2012 and No. 47/2012 that under certain circumstances, widespread or systematic imprisonment, or other severe deprivation of liberty in violation of fundamental rules of international law, may constitute crimes against humanity. The current case makes it necessary to reaffirm this. The duties to comply with international human rights that are peremptory and erga omnes norms, such as the prohibition of arbitrary detention, rests on all bodies and representatives of the State and on all individuals. 35. The Working Group holds that the detention of the petitioners in the present case is arbitrary and in violation of articles 8, 9, 10, 11, 13, 14, 18, 19 and 20 of the Universal Declaration of Human Rights and articles 8, 9, 12 and 14, 18, 19 of the International Covenant on Civil and Political Rights. Their detention thus falls within categories I, II and III of the categories applicable to the cases submitted to the Working Group. 36. The Working Group will remind the Democratic People’s Republic of Korea of its duties to comply with international human rights obligations not to detain arbitrarily, to release persons who are arbitrarily detained and to provide compensation to them. The Working Group has recalled above that, under certain circumstances, widespread or systematic imprisonment or other severe deprivation of liberty in violation of fundamental rules of international law may constitute crimes against humanity. The duties to comply with international human rights that are peremptory and erga omnes norms, such as the prohibition of arbitrary detention, rests not only on the Government but on all officials with relevant responsibilities, including judges, police and security officers and prison officers. No person can contribute to human rights violations. 6
