Denmark’s Directive on the Ban on Torture (2008) states:
Central to the issue [of the ban on torture and cruel, inhuman or degrading treatment or punishment] is that detainees are treated well and humanely.
Examples:
Was … the detainee’s health [taken into consideration]?
Does the detainee receive the necessary food and drink?
Was due attention paid to the detainee’s age, gender and state of health?
Did the detainee have the opportunity to ensure personal hygiene?
Were there acceptable sanitary conditions under detention?
