States Parties shall cooperate with each other and shall afford one another the greatest measure of mutual assistance with a view to assisting victims of enforced disappearance, and in searching for, locating and releasing disappeared persons and, in the event of death, in exhuming and identifying them and returning their remains. Article 16 1. No State Party shall expel, return (“refouler”), surrender or extradite a person to another State where there are substantial grounds for believing that he or she would be in danger of being subjected to enforced disappearance. 2. For the purpose of determining whether there are such grounds, the competent authorities shall take into account all relevant considerations, including, where applicable, the existence in the State concerned of a consistent pattern of gross, flagrant or mass violations of human rights or of serious violations of international humanitarian law. Article 17 1. No one shall be held in secret detention. 2. Without prejudice to other international obligations of the State Party with regard to the deprivation of liberty, each State Party shall, in its legislation: (a) Establish the conditions under which orders of deprivation of liberty may be given; (b) Indicate those authorities authorized to order the deprivation of liberty; (c) Guarantee that any person deprived of liberty shall be held solely in officially recognized and supervised places of deprivation of liberty; (d) Guarantee that any person deprived of liberty shall be authorized to communicate with and be visited by his or her family, counsel or any other person of his or her choice, subject only to the conditions established by law, or, if he or she is a foreigner, to communicate with his or her consular authorities, in accordance with applicable international law; (e) Guarantee access by the competent and legally authorized authorities and institutions to the places where persons are deprived of liberty, if necessary with prior authorization from a judicial authority; (f) Guarantee that any person deprived of liberty or, in the case of a suspected enforced disappearance, since the person deprived of liberty is not able to exercise this right, any persons with a legitimate interest, such as relatives of the person deprived of liberty, their representatives or their counsel, shall, in all circumstances, be entitled to take proceedings before a court, in order that the court may decide without delay on the lawfulness of the deprivation of liberty and order the person’s release if such deprivation of liberty is not lawful. 3. Each State Party shall assure the compilation and maintenance of one or more up-to-date official registers and/or records of persons deprived of liberty, which shall be made promptly available, upon request, to any judicial or other competent authority or institution authorized for that purpose by the law of the State Party concerned or any relevant international legal instrument to which the State concerned is a party. The information contained therein shall include, as a minimum: (a) The identity of the person deprived of liberty; (b) The date, time and place where the person was deprived of liberty and the identity of the authority that deprived the person of liberty; (c) The authority that ordered the deprivation of liberty and the grounds for the deprivation of liberty; (d) The authority responsible for supervising the deprivation of liberty; 6
