Criminal Justice Joint Inspection (CJJI)

CJJI is a product of long-standing cooperation between the four criminal justice inspectorates (of Constabulary and Fire & Rescue Services’the Crown Prosecution ServicePrisons; and Probation) which was formalised by the Police and Justice Act 2006.

We work together to address issues that involve more than one criminal justice agency and have a direct impact on the public who use the justice system. Working together produces a more rounded examination of issues that cut across the system and enables us to achieve more than if just one inspectorate acted alone.
