Further to the receipt of such information, the Working Group has requested additional information, including on the frequency of visits and calls, the leave required, whether calls can be made internationally, their confidentiality and how individuals in the facilities are made aware of this entitlement. 40. The Working Group reminds the Government of China that the Declaration on the Protection of All Persons from Enforced Disappearance recognizes the right to be held in an officially recognized place of detention and to be brought before a judicial authority promptly after detention in order to challenge the legality of the detention (art. 10 (1)). The same Declaration establishes the obligation of the detaining authorities to make available accurate information on the detention of persons and their place of detention to their family, counsel or other persons having a legitimate interest (art. 10 (2)). The Declaration also establishes the obligation to maintain in every place of detention an official up-to-date register of detained persons (art. 10 (3)) and provides that no circumstances whatsoever, whether a threat of war, a state of war, internal political instability or any other public emergency, may be invoked to justify enforced disappearances (art. 7). 41. The Working Group also notes information contained in the reply received from the Government of China on 20 September 2019 indicating that many envoys have visited the country, including the aforementioned facilities. In this sense, the Working Group wishes to reiterate its interest in undertaking a visit to China, as expressed in several communications transmitted since 2013.
