Many suspects and accused persons have intellectual or psychosocial impairments that, if not identified on time, may affect their ability to effectively and fairly participate in the criminal proceedings. Unlike age and physical illness, which are easily recognised, intellectual and psychosocial disabilities are not always visible and may remain unnoticed or misinterpreted. While some people may inform the criminal justice authorities of their disability, others may not be aware of their condition or try to hide it to avoid stigmatisation and intimidation.

This manual is designed to provide criminal justice practitioners with practical guidelines on how to identify and communicate with suspects and accused persons with intellectual and psychosocial impairments considering their vulnerable situation and respecting their rights.
