DEFENCE FOR CHILDREN INTERNATIONAL (DCI) - Belgium | Practical Guide A second important context in which children can be deprived of their liberty concerns the context of the child protection or child welfare system. In this context children can be deprived of their liberty for reasons of protection or education, or because children have disabilities or suffer from physical or mental problems. These children can be held in: ʺʺ Educational institutions and rehabilitation centres; ʺʺ Child detention schools; ʺʺ Psychiatric institution; ʺʺ Establishments for disabled children; ʺʺ Facilities where children are placed or hospitalised (voluntarily or not) for their own protection; ʺʺ Youth care institutions; ʺʺ Drug rehabilitation units; ʺʺ Isolation cells/rooms (even in open institutions) where children can be held for their own protection or for security or disciplinary purposes. Another context in which children can be deprived of their liberty is the context of migration. Unaccompanied or separated children, asylum-seeking children, migrant children can be deprived of their liberty alone or together with members of their family because they enter another country or have to leave a specific country. These children on the move can be held in: ʺʺ Reception or deportation centres; ʺʺ Retention centres; ʺʺ Return flights; ʺʺ Any form of administrative detention. Administrative detention is also used as a general term to cover forms of deprivation of liberty ordered by the administration for a variety of reasons, one of which is detention for public security reasons. Other forms include military detention or detention for committing administrative offences. This non-exhaustive list of contexts and forms of deprivation of liberty covers a wide range of places in which children find themselves deprived of their fundamental right to liberty. However, the different establishments and contexts should be isolated from one another and may well be strongly interrelated. For example, children in the context of criminal justice may end up in child protection facilities and the other way around. 24
