A/71/298 CCPR/C/IRL/CO/3). The Rome Statute and the Guidelines on the Conditions of Arrest, Police Custody and Pre-Trial Detention in Africa (Luanda Guidelines) expressly prohibit adverse inferences being drawn at trial from a suspect ’s exercise of the right to remain silent, finding that anything to the contrary may improperly imply that a suspect’s silence amounts to an admission of guilt and compromise the presumption of innocence. 78. The right to remain silent should equally apply, as a matter of law or policy, to prisoners of war, criminal detention relating to an armed conflict, detention of individuals considered to be civilian internees under international humanitarian law and administrative detention outside of armed conflict. With regard to interviews of witnesses and victims in the criminal justice system, courts alone may compel witness testimony. As a preventive measure against coercion and a matter of good practice, witnesses and victims should not be obliged to answer individual questions by which they could incriminate themselves during interviews. 19 4. Additional safeguards for vulnerable persons 79. Given that particular groups are more vulnerable during questioning, the protocol should contain specific provisions for, among others, children, women and girls, persons with disabilities, persons belonging to minorities or indigenous groups and non-nationals, including migrants (regardless of migration status), refugees, asylum seekers and stateless persons. The vulnerability of persons should be promptly identified for special consideration of their needs to be reflected in the conduct of interviews and implementation of additional safeguards. 80. With regard to the need to inform persons of their rights during questioning, additional safeguards are required for certain persons, with thorough explanations of the rights of children and persons with intellectual or psychosocial disabilities being provided directly to, among others, their parents, families, guardians or legal representatives (see general comment No. 35; and Inter-American Court of Human Rights, Tibi v. Ecuador). 81. A complementary safeguard is the presence of a support person during questioning, in addition to counsel. A child must never be subjected to questioning or requested to make any statement or to sign any document without the presence of a lawyer and, in principle, his or her caregiver or another appropriate adult (whose presence is encouraged to help to prevent coercion, reassure the child and limit potential traumatization), at all stages of the investigation and proceedings (see the United Nations Principles and Guidelines on Access to Legal Aid in Criminal Justice Systems; and Committee on the Rights of the Child, general comment No. 10 (2007) on children’s rights in juvenile justice). Persons who appear to suffer from psychosocial or intellectual disabilities should be assisted by an independent support person, whether a relative, legal guardian, mental health professional or social worker with relevant experience and training, during questioning. 82. Witnesses, victims, suspects and persons deprived of liberty who do not adequately speak or understand the language of questioning should be entitled to receive the free assistance of an independent, qualified and effective interpreter __________________ 19 20/25 See Vivienne O’Connor and Colette Rausch, eds.
