E/CN.4/2003/68 page 11 similar information should also be recorded regarding the actual detention, the state of health upon arrival at the detention centre, as well as the time the next of kin and lawyer were contacted and visited the detainee. Legal provisions should ensure that detainees are given access to legal counsel within 24 hours of detention. In accordance with the Basic Principles on the Role of Lawyers, all persons arrested or detained should be informed of their right to be assisted by a lawyer of their choice or a State-appointed lawyer able to provide effective legal assistance. The right of foreign nationals to have their consular or other diplomatic representatives notified must be respected. Security personnel who do not honour such provisions should be disciplined. In exceptional circumstances, under which it is contended that prompt contact with a detainee’s lawyer might raise genuine security concerns and where restriction of such contact is judicially approved, it should at least be possible to allow a meeting with an independent lawyer, such as one recommended by a bar association. In all circumstances, a relative of the detainee should be informed of the arrest and place of detention within 18 hours. At the time of arrest, a person should undergo a medical inspection, and medical inspections should be repeated regularly and should be compulsory upon transfer to another place of detention. Each interrogation should be initiated with the identification of all persons present. All interrogation sessions should be recorded and preferably video-recorded, and the identity of all persons present should be included in the records. Evidence from non-recorded interrogations should be excluded from court proceedings. The practice of blindfolding and hooding often makes the prosecution of torture virtually impossible, as victims are rendered incapable of identifying their torturers. That practice should be forbidden. Those legally arrested should not be held in facilities under the control of their interrogators or investigators for more than the time required by law to obtain a judicial warrant of pre-trial detention which, in any case, should not exceed a period of 48 hours. They should accordingly be transferred to a pre-trial facility under a different authority at once, after which no further unsupervised contact with the interrogators or investigators should be permitted. Specific preventive measures should be taken to ensure that the right to physical and mental integrity is fully guaranteed during all transfers, especially from the place of arrest to the initial detention facility; (h) Administrative detention often puts detainees beyond judicial control. Persons under administrative detention should be entitled to the same degree of protection as persons under criminal detention. At the same time, countries should consider abolishing, in accordance with relevant international standards, all forms of administrative detention; (i) Provisions should give all detained persons the ability to challenge the lawfulness of the detention, e.g. through habeas corpus or amparo. Such procedures should function expeditiously; (j) Countries should take effective measures to prevent prisoner-on-prisoner violence by investigating reports of such violence, prosecuting and punishing those responsible, and offering protective custody to vulnerable individuals, without marginalizing them from the prison population more than is required by the need for protection and without putting them at further risk of ill-treatment. Training programmes should be envisaged to sensitize prison officials to the importance of taking effective steps to prevent and remedy prisoner-on-prisoner abuse and to provide them with the means to do so.
