A/69/44 articles 21 and 22 of the Convention in order to recognize the competence of the Committee to receive and consider communications. (33) The Committee invites the State party to ratify the core United Nations human rights treaties to which it is not yet a party, namely, the International Convention for the Protection of All Persons from Enforced Disappearance, the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families and the Second Optional Protocol to the International Covenant on Civil and Political Rights. In addition, the State party should consider becoming a party to the Convention relating to the Status of Stateless Persons (1954) and the Convention on the Reduction of Statelessness (1961). (34) The State party is requested to disseminate widely the report it submitted to the Committee and the Committee’s concluding observations, in appropriate languages, through official websites, the media and non-governmental organizations. (35) The Committee requests the State party to provide, by 23 May 2015, follow-up information in response to the Committee’s recommendations related to (a) ensuring or strengthening legal safeguards for persons in detention; (b) conducting prompt, impartial and effective investigations into cases of the involvement of members of law enforcement agencies in unlawful killings; and (c) prosecuting suspects and sanctioning perpetrators of torture or ill-treatment, as specified in paragraphs 11, 13 and 28 (b) of the present concluding observations. In addition, the Committee requests follow-up information on the regulation of the absolute prohibition of torture in the Constitution and the use of alternative measures of detention, as contained in paragraphs 10 and 24 of the present concluding observations. (36) The State party is invited to submit its next report, which will be its second periodic report, by 23 May 2018. For that purpose, the Committee invites the State party to agree, by 23 May 2015, to report under its optional reporting procedure, which entails the transmittal, by the Committee to the State party, of a list of issues prior to the submission of the report. The State party’s response to this list of issues will constitute, under article 19 of the Convention, its next periodic report. 69. Thailand (1) The Committee against Torture considered the initial report of Thailand (CAT/C/THA/1) at its 1214th and 1217th meetings (CAT/C/SR.1214 and 1217), held on 30 April and 1 May 2014, and adopted the following concluding observations at its 1239th meeting (CAT/C/SR.1239), held on 16 May 2014. A. Introduction (2) The Committee welcomes the submission of the initial report of Thailand (CAT/C/THA/1) and the common core document (HRI/CORE/THA/2012). However, it regrets that the report was submitted with a delay of five years, which prevented it from monitoring the implementation of the Convention in the State party during that time. The Committee also notes that while the report generally follows the guidelines on the form and content of initial reports (CAT/C/4/Rev.3), statistical information on the implementation of the Convention in the State party is lacking. (3) The Committee appreciates the open and constructive dialogue with the high-level delegation of the State party and the additional information provided by the delegation. (4) The Committee is deeply concerned at the declaration of martial law throughout Thailand, since its recent dialogue with the State party. It emphasizes that the State party should adhere strictly to the absolute prohibition of torture and ensure that the application of martial law does not, under any circumstances, contradict the rights guaranteed in the GE.14-12596 149
