CAT/C/CHN/CO/5 whether an investigation took place on the alleged use of excessive force and other human rights violations by military officers in Beijing following the Tiananmen Square protests, resulting in the death of hundreds of civilians. The Committee draws the attention of the State party to its general comment No. 3 (2013) on the implementation of article 14 by States parties, in which it indicates that a State’s “failure to investigate, criminally prosecute, or to allow civil proceedings related to allegations of acts of torture in a prompt manner, may constitute a de facto denial of redress and thus constitute a violation of the State’s obligations under article 14”. The Committee is equally concerned at the failure of the State party to inform families of the whereabouts of their relatives who participated in the protests and are still in detention, and of persons who have allegedly been detained for organizing activities or expressing views to memorialize the event on the occasion of its twenty-fifth anniversary, in 2014 (arts. 12 and 14). 54. Recalling its previous recommendation (see CAT/C/CHN/CO/4, para. 21), the Committee urges the State party to ensure that: (a) All allegations of excessive use of force, torture and other ill-treatment perpetrated by State officials on or following the 3 and 4 June 1989 suppression of protests are effectively, independently and impartially investigated by an independent authority and that perpetrators are prosecuted and, if found guilty, punished; (b) Victims and their families obtain full reparation; (c) Families of those arrested or disappeared in connection with the 1989 events and its memorialization are informed of the fate of their relatives; (d) Victims, their families, witnesses and others who intervene on their behalf are protected at all times against retaliation for claiming their legitimate right to obtain redress and accountability for past violations; (e) The legal safeguards and due process rights of those detained in connection with the 1989 events, or with current activities to memorialize it, should be fully respected. Lesbian, gay, bisexual, transgender and intersex persons 55. The Committee is concerned about reports that private and publicly run clinics offer the so-called “gay conversion therapy” to change the sexual orientation of lesbian and gay persons, and that such practices include the administration of electroshocks and, sometimes, involuntary confinement in psychiatric and other facilities, which could result in physical and psychological harm. While noting that, in December 2014, a Beijing court ordered one such clinic to pay compensation for such treatment, the Committee regrets the State party’s failure to clarify whether such practices are prohibited by law, have been investigated and ended, and whether the victims have received redress (arts. 10, 12, 14 and 16). 56. The State party should: (a) Take the necessary legislative, administrative and other measures to guarantee respect for the autonomy and physical and personal integrity of lesbian, gay, bisexual, transgender and intersex persons and prohibit the practice of so-called “conversion therapy”, and other forced, involuntary or otherwise coercive or abusive treatments against them; (b) Ensure that health professionals and public officials receive training on respecting the human rights of lesbian, gay, bisexual, transgender and intersex persons, including their rights to autonomy and physical and psychological integrity; 15
