A/70/212 Systematic reform of laws, policies and practices 107. In collaboration with representatives of minorities, Governments should elaborate and adopt a national strategy designed to prevent discrimination against minorities within the criminal justice system and to increase the effective participation of minorities within the system. 108. Police forces should collaborate with minorities at the local level in establishing permanent liaison mechanisms that are controlled or jointly controlled by the minorities themselves, developing local strategies, keeping open the lines of communication and building mutual trust. Representation and participation of minorities in the administration of justice 109. States should ensure the recruitment, retention and promotion of members of underrepresented minorities in the police, the judiciary, prosecution services, the legal profession and prison staff, including through specially targeted measures developed in consultation with minority groups and existing minority staff. 110. The Office of the United Nations High Commissioner for Human Rights should consider producing guidelines on integration with diversity in policing, thereby resuming the process initiated under the former Working Group on Minorities. Training 111. All staff working in the criminal justice system should receive training, conducted with the participation of minorities, in non-discrimination and cultural competency. Oversight mechanism and accountability 112. National human rights institutions should consider establishing a specific mechanism dedicated to addressing the rights of minorities, including within the criminal justice system. 113. National institutions responsible for oversight of police, as well as independent regulatory bodies for the judiciary, prosecutors and legal profession, should systematically assess and report on the situation of minorities within the criminal justice process, and take action when they observe discrimination. 26/27 15-12578
