20 years of combating torture: CPT General Report 2008-2009 84. It is essential that newly arrived irregular migrants be immediately given information on these rights in a language they understand. To this end, they should be systematically provided with a document explaining the procedure applicable to them and setting out their rights in clear and simple terms. This document should be available in the languages most commonly spoken by the detainees and, if necessary, recourse should be had to the services of an interpreter. General safeguards during deprivation of liberty 85. Every instance of deprivation of liberty should be covered by a proper individual detention order, readily available in the establishment where the person concerned is being held; and the detention order should be drawn up at the outset of the deprivation of liberty or as soon as possible thereafter. This basic requirement applies equally to irregular migrants who are deprived of their liberty. Further, the fundamental safeguards of persons detained by law enforcement agencies are reinforced if a single and comprehensive custody record is kept for every such person, recording all aspects of his/ her custody and all action taken in connection with it. 86. Detained irregular migrants should benefit from an effective legal remedy enabling them to have the lawfulness of their deprivation of liberty decided speedily by a judicial body. This judicial review should entail an oral hearing with legal assistance, provided free of charge for persons without sufficient means, and interpretation (if required). Moreover, detained irregular migrants should be expressly informed of this legal remedy. The need for continued detention should be reviewed periodically by an independent authority. 87. Arrangements should be made enabling detained irregular migrants to consult a lawyer or a doctor on an ongoing basis, and to receive visits from NGO representatives, family members or other persons of their choice, and to have telephone contact with them. If members of the same family are deprived of their liberty under aliens legislation, every effort should be made to avoid separating them. 40
