A/HRC/20/24 should be considered only when someone presents a risk of absconding or presents a danger to their own or public security 70. Administrative detention should not be applied as a punitive measure for violations of immigration laws and regulations, as those violations should not be considered criminal offences. 71. The Special Rapporteur calls on States to adopt a human rights-based approach to migration and review their legislation and policies on detention of migrants, ensuring that national laws are harmonized with international human rights norms that prohibit arbitrary detention and inhumane treatment. 72. The Special Rapporteur calls on States to consider progressively abolishing the administrative detention of migrants. In the meantime, Governments should take measures to ensure respect for the human rights of migrants in the context of detention, including by: (a) Ensuring that procedural safeguards and guarantees established by international human rights law and national law are applied to any form of detention. In particular, grounds for detention of migrants must be established by law. A decision to detain should only be taken under clear legal authority, and all migrants deprived of their liberty should be informed in a language they understand, if possible in writing, of the reasons for the detention and be entitled to bring proceedings before a court, so that the court can decide on the lawfulness of the detention. Migrants in detention shall be assisted, free of charge, by legal counsel and by an interpreter during administrative proceedings; (b) Ensuring that migrants in detention are accurately informed of the status of their case and of their right to contact a consular or embassy representative and members of their families. Migrants and their lawyers should have full and complete access to the migrants’ files; (c) Ensuring that the law sets a limit on the maximum length of detention pending deportation and that under no circumstance is detention indefinite. There should be automatic, regular and judicial review of detention in each individual case. Administrative detention should end when a deportation order cannot be executed; (d) Ensuring that migrants under administrative detention are placed in a public establishment specifically intended for that purpose or, when this is not possible, in premises other than those intended for persons imprisoned under criminal law. The use of privately run detention centres should be avoided. Representatives of, inter alia, national human rights institutions, OHCHR, UNHCR, ICRC and NGOs should be allowed access to all places of detention. All migrant detention facilities – whatever their form – should be subject to a common set of standards, policies and practices and should be monitored by an independent central authority that is dedicated to ensuring compliance with the common set of standards, policies and practices; (e) Ensuring that the Body of Principles for the Protection of All Persons under Any Form of Detention and Imprisonment are applied to all migrants under administrative detention. The principles include the provision of a proper medical examination as promptly as possible and medical treatment and care whenever necessary and free of charge; the right to assistance, free of charge if necessary, of an interpreter and a legal counsel; the right to communicate with the outside world, in particular family and counsel; the right to obtain, within the limits of available public resources, educational, cultural and informational material; 18
