A/HRC/30/36 I. Introduction 1. The Working Group on Arbitrary Detention was established by the Commission on Human Rights in its resolution 1991/42 and entrusted with the investigation of instances of alleged arbitrary deprivation of liberty, according to the standards set forth in the Universal Declaration of Human Rights and the relevant international instruments accepted by the States concerned. The mandate of the Working Group was clarified and extended by the Commission in its resolution 1997/50 to cover the issue of administrative custody of asylum seekers and immigrants. At its sixth session, the Human Rights Council assessed and confirmed the mandate of the Working Group (Council resolution 6/4). On 26 September 2013, in its resolution 24/7, the Council extended the Working Group’s mandate for a further three-year period. 2. During the period 1 January–31 May 2014, the Working Group was composed of Shaheen Sardar Ali (Pakistan), Mads Andenas (Norway), Roberto Garretón (Chile), El Hadji Malick Sow (Senegal) and Vladimir Tochilovsky (Ukraine). On 1 June 2014, Sètondji Roland Jean-Baptiste Adjovi (Benin) and José Antonio Guevara Bermúdez (Mexico) started their functions as members of the Working Group, replacing Mr. Sow and Mr. Garretón, respectively. On 1 August 2014, Seong-Phil Hong (Republic of Korea) started his functions as a member of the Working Group, replacing Ms. Ali. 3. During 2014, Mr. Andenas was the Chair-Rapporteur of the Working Group and Vladimir Tochilovsky its Vice-Chair. At the seventy-second session of the Working Group, Mr. Hong was elected as Chair-Rapporteur, Mr. Guevara Bermúdez as First Vice-Chair and Mr. Adjovi as Second Vice-Chair. II. Activities of the Working Group in 2014 4. During the period 1 January to 31 December 2014, the Working Group held its sixty-ninth, seventieth and seventy-first sessions. It undertook an official mission to New Zealand, from 24 March to 7 April 2014, and two follow-up visits, one to Germany, from 12 to 14 November 2014 and one to Italy, from 7 to 9 July 2014 (see A/HRC/30/36/Add.2, 4 and 3, respectively). 5. On 24 March 2014, the Government of Nauru cancelled the visit of the Working Group scheduled to take place from 14 to 19 April 2014, owing to “unforeseen circumstances”. The Government has not yet accepted the new visit dates proposed by the Working Group. 6. Pursuant to Human Rights Council resolution 20/16, the Working Group adopted at its seventy-second session the draft basic principles and guidelines on remedies and procedures on the right of anyone deprived of his or her liberty by arrest or detention to bring proceedings before court. The draft basic principles and guidelines are aimed at assisting Member States in fulfilling their obligation to avoid arbitrary deprivation of liberty, in compliance with international human rights law. 7. The Working Group submitted to the Human Rights Council at its twenty-seventh session a report in which it compiled international, regional and national legal frameworks on the right to challenge the lawfulness of detention before court (A/HRC/27/47). The report was based largely on the responses submitted by a wide range of stakeholders to a questionnaire sent by the Working Group, in which it requested details on the treatment of the right in the respective legal frameworks. 4
