Children living in prison with their mothers may be at heightened risk of suffering violence, abuse and conditions of confinement that amount to torture or ill-treatment. In this context, the imprisonment of pregnant women and women with young children must be reduced to a minimum. Girls in detention 29. Girls in the criminal justice system are at particular risk of experiencing torture and ill-treatment. The majority have prior histories of abuse and violence that serve as primary predictors of their entry into the juvenile justice system. Girls’ particular physical and mental health needs often go unrecognized and incarceration itself tends to exacerbate trauma, with girls suffering disproportionately from depression and anxiety and exhibiting a higher risk of self-harm or suicide than boys or adults. Many States lack facilities for separating girls from adults or boys, which significantly increases the risks of violence, including sexual violence.13 The employment of male guards in girls’ facilities significantly increases the risk of abuse, while girls held in remote, segregated facilities are isolated and have limited contact with their families. 30. Many States use the criminal justice system as a substitute for weak or non-existent child protection systems, leading to the criminalization and incarceration of disadvantaged girls who pose no risk to society and are instead in need of care and protection by the State.14 The Special Rapporteur recalls that the deprivation of liberty of children is inextricably linked with ill-treatment and must be a measure of last resort, used for the shortest possible time, only when it is in the best interest of the child and limited to exceptional cases (A/HRC/28/68). Accordingly, the lack of gender-centred juvenile justice policies directly contributes to the perpetration of torture and ill-treatment of girls. There is an urgent need for policies that promote the use of such alternative measures as diversion and restorative justice, incorporate broad prevention programmes, build a protective environment and address the root causes of violence against girls. Failure to support girls in detention with adequate and complete information about their rights in a comprehensible manner and to provide assistance with reporting complaints in a safe, supportive and confidential manner further aggravates mistreatment. Migrants and refugees 31. Migrants, asylum seekers and refugees worldwide face grave human rights violations during the migration process. Physical violence, threats and abductions by smugglers, traffickers and organized criminal groups are common. Women and girls are particularly vulnerable to sexual violence, exploitation and slavery along migration routes. Such abuses can amount to torture and ill-treatment and States’ failure to properly screen migrants and refugees, identify victims of torture and provide appropriate care and support can retraumatize victims and inflict additional mistreatment. 32. Upon interception or rescue, migrants and refugees tend to be criminalized and detained in substandard and overcrowded conditions amounting to torture or ill-treatment. Unsanitary conditions and inadequate medical care, including lack of access to reproductive care, affect women in particular. Many facilities fail to separate female and male prisoners, leading to heightened risks of sexual violence from other detainees or guards 13 14 Committee on the Rights of the Child, general comment No. 10 (2007) on children’s rights in juvenile justice.
