The present report is submitted pursuant to Human Rights Council resolution 45/30, in which the Council requested the United Nations High Commissioner for Human Rights to prepare a report on the rights of the child and family reunification. All children have the right to family life, yet millions worldwide are suffering preventable separation from their families and associated violations of their rights. In the present report, the High Commissioner recommends that States move to develop global, child rights-based guiding principles and a global strategy for family reunification.
