A/HRC/39/46 2015, 18 November 2016 and 19 January 2018. The Working Group hopes that a positive reply will be received soon. Sri Lanka 128. The Working Group notes the establishment of the Office of Missing Persons and urges the Government to ensure its functioning and implementation and take into account the recommendations made after the visit carried out in November 2015 (see A/HRC/33/51/Add.2, paras. 79–80). 129. The Working Group reminds the State that the families of the disappeared in Sri Lanka have waited too long to know the truth about the fate or whereabouts of their loved ones. This is an absolute right under the Declaration and an obligation that the State should meet in accordance with international law. It also reminds the State that the victims of enforced disappearance and their families should obtain redress and have the right to adequate compensation, including the means for as complete a rehabilitation as possible. Sudan 130. The visit to Sudan scheduled for November 2017 was postponed due to a lack of understanding about the terms of reference for the visit. The Working Group greatly regrets that, in spite of a preliminary visit undertaken by the Chair-Rapporteur of the Working Group in order to clarify the terms of reference on 5 and 6 December 2017 — and an agreement in principle about the new dates in March 2018 — the Government has never officially accepted the visit. Syrian Arab Republic 131. The Working Group continues to be gravely concerned (see A/HRC/36/39 para. 105) about the situation in the Syrian Arab Republic, which facilitates the occurrence of enforced disappearances. It reiterates article 7 of the Declaration, which provides that no circumstances whatsoever may be invoked to justify enforced disappearances. 132. The Working Group reiterates its call to the Security Council to consider referring the situation in Syria to the International Criminal Court (see A/HRC/27/49, para. 99, and A/HRC/33/51, para. 103). 133. On 19 September 2011, the Working Group requested an invitation to visit the country. No response has yet been received from the Government in spite of reminders sent on 2 September 2013, 27 October 2014, 27 November 2015, 18 November 2016 and 19 January 2018. The Working Group hopes that a positive reply will be received soon. Thailand 134. The Working Group appreciates the meeting held during its 115th session. It recommends that the draft act on prevention and suppression of torture and enforced disappearance be swiftly adopted and that a definition of enforced disappearance in conformity with the Declaration and the Convention be included therein. The act should also prohibit refoulement to another country where the concerned individual may be at risk of enforced disappearance, in conformity with article 8 of the Declaration. 135. On 30 June 2011, the Working Group requested an invitation to visit the country. No positive response has yet been received from the Government in spite of reminders sent on 8 November 2012, 2 September 2013, 28 October 2014, 27 November 2015, 18 November 2016 and 19 January 2018. The Working Group hopes that a positive reply will be received soon. 24
