48 112. The Court, approvingly notices the attitude of the State towards this important matter. On such point, the Court orders that Colombia must adopt the necessary measures to strengthen existing control mechanisms in state arrest centers, for the purpose of guaranteeing adequate arrest conditions and respect for the due process of the law. Such control mechanisms must include, inter alia: a) medical examinations of every arrestee or convict, according to standard medical practice. Specifically, examinations shall be conducted under medical control, in private and never in the presence of security staff or other government officials. Such examinations shall be conducted as promptly as possible after the admission of the arrested or imprisoned person to the place of arrest or imprisonment, and thereafter medical care and treatment shall be provided whenever necessary; b) regular psychological assessments of staff in charge of the custody of persons arrested, in order to ensure their adequate mental health condition; and c) frequent access to such centers for staff ofn the appropriate human rights surveillance and protection organizations.48 X COSTS AND EXPENSES Argument by the Commission 113.
