A/58/275 7. National human rights institutions and NGOs 50. National human rights institutions, NGOs and academics can play a crucial role in the protection of the human rights of migrants by analysing national legislation, monitoring its impact on the rights of migrants and making concrete recommendations in that regard. Monitoring the implementation of national legislation by competent authorities and agencies is also crucial as often, abuses, arbitrary treatment and discrimination against migrants are justified by invoking existing legislation and/or regulations. National human rights institutions can also make very valuable contributions to the development of national policies that have an impact on the human rights of migrants. They can also encourage dialogue at the national level and raise awareness about the situation of migrants. Through campaigns and public activities, national human rights institutions can also help fight negative stereotyping and promote a positive image of migration, thereby preventing racism and xenophobia. 51. National human rights institutions and NGOs can provide legal and psychological assistance to migrants. They can assist migrants who wish to file complaints by facilitating contacts with relevant agencies and authorities. They can also assist them in legal and administrative proceedings against the authorities and monitor the evolution of individual cases. In that connection, the Special Rapporteur believes that it is important that representatives of national human rights institutions visit migrant detention centres or other detention facilities where migrants are held in administrative detention. IV. Good practices observed by the Special Rapporteur 52. In discharging her mandate, the Special Rapporteur has come across a number of interesting initiatives, projects and activities, implemented by Governments and civil society, to address the challenges referred to in chapter II of this report. The examples mentioned below are not exhaustive. However, the Special Rapporteur believes that it is important to increase efforts to exchange information on the ways in which Governments, NGOs and international and regional organizations around the world are trying to promote respect for the human rights of migrants throughout the migration process. Prevention of irregular migration and combating trafficking 53. In some countries in Asia, commissions or committees on irregular migrant workers have been set up to undertake studies on occupation and employment structures to determine if irregular migrants could fill the vacancies in the labour market. In follow-up to the visit of the Special Rapporteur, the Government of Mexico reported that it had implemented a Human Development Opportunities Programme for the promotion of local development in order to prevent irregular migration. The programme is inter-institutional and aims at developing capacities in the poorest communities by direct assistance in the fields of health, food and education. The Women’s Institute also participates in the Programme. 17
