A/HRC/35/20 international standards. This analysis has been widely referenced, including by the Supreme Court of Nepal in its decision to strike down the amnesty clauses in the enabling law. OHCHR Cambodia Country Office effectively combines technical cooperation and human rights monitoring 12. OHCHR opened its first field presence in Cambodia in 1993. Its long-term presence in the country and its thorough understanding of the human rights challenges faced by the authorities have helped it to select priority technical cooperation initiatives, together with the Government. The human rights monitoring activities carried out by the OHCHR office in Cambodia since 1993 have substantially contributed to that understanding of the human rights situation and hence to the sound design of the technical cooperation programme in the country. 13. In April 2015, the Board of Trustees held its annual session in Cambodia, which allowed first-hand observation of successful OHCHR technical cooperation with the Cambodian justice system, particularly with the justice and interior ministries. OHCHR technical cooperation efforts in Cambodia include — among other issues — justice system reform, prison reform, and implementation of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment and its Optional Protocol.3 14. During its session, the Board of Trustees visited Correctional Centre 1, together with the authorities. It witnessed substantial overcrowding and therefore commended the efforts by OHCHR to support solutions to the current situation of large numbers of persons in pretrial detention. OHCHR has also provided appreciated technical support for the formulation and implementation of the new Code of Criminal Procedure. As a complementary measure, OHCHR and the United Nations Development Programme (UNDP) have supported infrastructure improvements to the Cambodian justice system, including the construction of the Kampong Speu court.4 15. It is important to note that the Board of Trustees found that OHCHR priorities in Cambodia were in line with the expectations of national stakeholders, and that the OHCHR country office continued to be seen, more than 20 years after its establishment, as a reliable partner with the capacity to respond effectively to requests for assistance. 5 OHCHR support for security sector reform 16. In 2012, OHCHR conducted a mapping exercise of its global support for security sector reform. The survey indicated that almost all OHCHR field presences (56 at the time) engaged with law enforcement, military and intelligence agencies in one form or another. The lessons learned point to the importance of taking a systemic approach to technical cooperation in the area of security sector reform, and to avoid isolated and often unsustainable human rights training with individual units. 17. In the experience of OHCHR, training is only one of many possible interventions to enhance the respect for human rights in a law enforcement organization. Before the decision to carry out human rights training is taken, it is essential to analyse the context in which such training is to take place, the challenges that it will seek to address and the complementary actions that will be necessary to ensure the training’s effectiveness. 18. As experienced by OHCHR field presences, there is little or no point in engaging in one-off briefings on human rights except where this is linked to other capacity-building initiatives. Sustainable engagements include engaging with internal reform processes and with training academies, regarding curriculum development, as well as in-service training. 19. Cooperation projects should closely meet the needs of the recipient entities and be based on the beneficiary profile of the given security force. There are many good examples of security sector reform cooperation projects designed jointly between OHCHR and the 3 4 5 4 See A/HRC/29/48, paras. 14-24. Ibid., para. 19. Ibid., para. 24.
