National human rights institutions should also include process indicators to ensure that the rights of detainees are protected: information on these must be collected. The Standard Minimum Rules for the Treatment of Prisoners require a complaints system for detainees, for instance. Other standards include providing specific human rights training to officials who come in contact with detainees. Planning for monitoring should identify the main process indicators that apply in the local circumstances. There should also be a process for families of detained persons to report irregularities to the NHRI, if it has a complaints procedure. National actions may also support efforts by the international human rights system, especially the Working Group on Arbitrary Detention.
