Detention monitoring rity units have been prepared. The Commission was nevertheless critical of the practice of using additional restraints for highly agitated individuals in security cells. The Commission requested that the facility ceases the use of such – in its view unnecessary – restraining measures and that, without exception, any further use thereof be officially recorded and accompanied by medical surveillance. Lastly, the Commission expressed its regret that no privacy room had been set up for long-term detainees.  igh Security Unit of the Lenzburg Correctional Facility H (Aargau)7 During its follow-up visit in August 2017 at the Lenzburg Correctional Facility, the Commission put particular attention to the detention conditions of detainees held in high security units. The Commission specifically assessed the criteria for ordering a placement in such units as well as the procedural aspects. Taking into consideration its previous recommendations, the Commission reiterated its position that the ordering of solitary confinement should be discontinued in cases where it is grounded solely on a risk of flight.8 With regard to the review of continued detention in solitary confinement, the Commission recommended that the measure should be reviewed at least every three months in accordance with international law. Lastly, the Commission found that the internal regulations on access to the telephone remained too restrictive in the facility. The Commission thus suggested that the rules in question be eased.
