A/HRC/42/31 expedite cases and make increased use of alternatives to custody. When the anti-drug campaign was renewed for the fourth time in March 2019, 56 per cent of all prisoners were charged or convicted of drug-related offences while only 29 per cent were serving a final enforceable sentence. The campaign has taken a particular toll on women: over 73 per cent of the total female prison population are women and girls detained or convicted of drugrelated charges. 24. OHCHR continued to work closely with prison registry officers and legal aid organizations to identify cases of prisoners held in excessive detention and followed up with the courts to ensure their release. In April 2019, OHCHR resumed technical assistance to support the development of a database for prisons. The database aims at enabling prison authorities to better keep track of multiple charges and sentences and the relevant time limits applicable to different categories of prisoner, in particular those detained pretrial, and to better monitor time served to facilitate timely releases and timely applications for sentence reduction or pardon. 25. With the International Committee of the Red Cross, OHCHR advocated for the finalization of long-awaited regulations on minimum standards for prison construction and renovation, foreseen in the 2011 Prison Law. The document reflects several recommendations made by OHCHR in previous years. As part of a broader programme on access to justice for persons with disabilities, OHCHR also partnered with the Cambodian Disabled People’s Organization, which started a mapping of the conditions and treatment of prisoners with disabilities in five prisons. 26. OHCHR continued to collaborate with trainers from the General Department of Prisons and the Professional Training Centre for Prison Officials of the Police Academy of Cambodia to improve training of prison personnel. In May, September and December 2018 as well as in May 2019, it co-organized four joint study visits to four prisons for 231 prison staff trainees and their 20 trainers, which allowed them to contextualize their learning and teaching in real prison environments. In May and September 2018 as well as in May 2019, OHCHR delivered lectures on the prevention of torture for 191 new recruits. OHCHR also worked with the Department and Academy trainers, including younger trainers, to review the human rights content of their curriculum. In the latest review meeting, held in November 2018, the trainers noted the pedagogical value of the prison visits and requested assistance in ensuring sustainable funding for the training programme. 27. OHCHR worked with national and provincial health and prison authorities to equip rooms at the referral hospital in Siem Reap Province with appropriate security features. Three secure rooms will be operational later in 2019. This will facilitate the hospitalization of sick prisoners without heightened escape risks, enabling the detainee patients to enjoy their right to health without being restrained by chains or handcuffs. 28. OHCHR continued to support the National Committee against Torture, which is the Cambodian national preventive mechanism, to raise awareness of the existence and mandate of the mechanism among authorities at places of deprivation of liberty as well as the public. In July 2018, the Deputy Prime Minister and Minister of Interior issued a letter to all national- and subnational-level authorities to clarify the National Committee’s independent mandate and its power to conduct unannounced preventive visits to all places of deprivation of liberty. In December 2018, OHCHR and the National Committee coorganized a national sensitization workshop on the roles and duties of this mechanism. Opening the workshop, which brought together 185 participants (including 13 females), including all prison directors, police commissioners, gendarmerie commanders, provincial governors and immigration, drug and social affairs authorities as well as representatives from non-governmental organizations and development partners, the Deputy Prime Minister emphasized these important messages once again. OHCHR continues to work with the National Committee in the development of its tools and methods. IV. Strengthening the rule of law 29.
