DEFENCE FOR CHILDREN INTERNATIONAL (DCI) - Belgium | Practical Guide C. SETTING AN OVERALL TIMEFRAME FOR THE MONITORING PROGRAMME The timeframe for the monitoring programme should be based on the following elements: ʺʺ the duration of the monitoring body’s mandate; ʺʺ the time required for the accomplishment of a complete monitoring cycle (preparation - implementation – follow-up of the visit); ʺʺ when possible, the regularity of the visits – See – Section 3.3. – p.32; ʺʺ the capacity to plan unannounced and/or ad hoc visits. D. SELECTING PLACES WHERE CHILDREN ARE DEPRIVED OF THEIR LIBERTY TO VISIT Before selecting the places to be visited in priority, each monitoring body should establish a complete and updated mapping of the places where children are deprived of their liberty located in its scope of intervention and gather all useful information in relation to these places See – Section 2. – p.23 & Section 4.1. / A. – p.48. The order in which the facilities will be visited will then depend on the specific objectives set by the monitoring body. The following (non-exhaustive) criteria – alone or together – may help the monitoring body to select the different places to be considered: The risk (potential or actual) to which children are exposed: ʺʺ Police custody (at the time of arrest, during transportation or questioning); ʺʺ Pre-trial detention centres or remand homes; ʺʺ Facilities where children are held together with adults (pre-trial detention centres or remand homes, police custody, immigration detention facilities, prisons, etc.); ʺʺ Solitary confinement rooms or other similar rooms in which children are completely isolated (isolation cells, time out cells, separation units, etc.); ʺʺ Places not traditionally related to detention (hospitals, immigration centres, drug rehabilitation units, etc.). 50
