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 Service; Prisons; 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.

This plan sets out the proposed programme of inspections of the Criminal Justice System for 2027–29. Some of the inspections will be carried out jointly by two or more of our inspectorates. Others may combine findings from single-agency inspections or may take a different approach.
