A/HRC/14/30/Add.3 (d) Make available data on the channels of migration; (e) Improve data collection efforts on return migration. 83. Concerning independent bodies, such as the national human rights institutions and the children’s commissioners, the Special Rapporteur encourages them to operate within the framework of the Paris Principles and to continue cooperating among themselves, as well as to adopt a coordinated approach based, inter alia, on the Santa Cruz Declaration on the role of national human rights institutions in dealing with migration and the Seoul Declaration on upholding human rights during conflict and while countering terrorism. 84. The Special Rapporteur recommends that the Government ensure in law and practice respect for the prohibition of discrimination and establish monitoring mechanisms to avoid disproportionate scrutiny and psychological mistreatment of persons entering the United Kingdom with valid documentation, as well as take all necessary measures to prohibit in law and practice the use of profiles that reflect unexamined generalizations, such as profiling based on ethnic or national origin or religion. 85. The Special Rapporteur encourages the Government to establish programmes that promote a human rights-based approach to migration and the protection of the human rights of migrants, regardless of their immigration status, as good practices in migration governance.
