52 other ombudsman decisions of importance to the rights of persons deprived of their liberty well acquainted with the instructions that exist regarding the use of mechanical restraint and of the decision-makers responsible specifying the provision under which the coercive measure is being implemented.17 Camera surveillance The issue of the camera surveillance of prison inmates has been subject to a number of different deliberations. One case concerns the issue of camera surveillance of living quarters in the isolation section of a high-security unit.18 The Parliamentary Ombudsman’s decision stated that in those cases where the prison does not decide that an inmate is to be under constant supervision, the camera in the living quarters should be covered. This ensures that inmates know when they are being monitored. The Parliamentary Ombudsman has also issued a statement concerning camera surveillance in connection with the taking of urine samples in the normal section of a high-security unit. According to the Prison and Probation Service, camera surveillance can serve as a complement to the witness function during sample taking and thereby protect the inmate against improper conduct. The Parliamentary Ombudsman has found no reason to question this. According to the Parliamentary Ombudsman, the inmates are under all circumstances closely supervised during sample taking. Therefore, the Parliamentary Ombudsman finds no reason to question this camera surveillance.19 One case involved a inmate in isolation at a prison who had been under camera surveillance for an extended period. It emerged that the personnel responsible for this surveillance via camera were in a different building to the inmate. The prison had had the inmate in isolation under camera surveillance for eight weeks. The prison made the assessment that there was a risk of the inmate harming himself. The Parliamentary Ombudsman stated that surveillance can be done in two ways: either through constant supervision by staff adjacent to the room where the inmate is, or through patrols at certain times. During patrols, camera surveillance can serve as a complement. The prison was seriously criticised for only having exercised supervision through camera surveillance since this prevented personnel from carrying out an immediate intervention in the event of an act of self-harm.20 Treatment The Parliamentary Ombudsman has criticised deficiencies in the supervision of inmates in police cells.21 There is also one case in which the Parliamentary 17 Ref. no. 1455-2013 18 Ref. no. 3978-2010 19 Ref. no. 4632-2010 20 Ref. no. 115-2013 21 Ref. no. 2112-2010, ref. no. 5244-2011, ref. no. 5802-2011, ref. no. 4626-2013, ref. no. 1632-2014
