What is a Non-Departmental Public Body (NDPB) and how do they work?
A Non-Departmental Public Body (NDPB) is a classification applied by Government to certain types of public bodies. The NDPBs are not an integral part of a government department and carry out their work at arm’s length from Ministers, although Ministers are ultimately responsible to Parliament for the activities of the bodies sponsored by their department.
NDPBs such as CJI are not created to carry out Ministerial orders or policy and are more or less self determining.
Like most NDPBs CJI was established under statute and at that time was accountable to Parliament rather than Government.  Following devolution CJI became accountable to the Northern Ireland Assembly.
This arrangement facilitates more financial independence, since government is obliged to provide funding to meet statutory obligations.
CJI is an Executive NDPB. An executive NDPB delivers a particular public service and is able to employ its own staff and is allocated its own budget.  It is however different to other NDPBs as it is an NDPB in the person of the Chief Inspector of Criminal Justice.
CJI is one of nine NDPBs in Northern Ireland. Others include the Equality Commission for NI; the NI Human Rights Commission (NIHRC), the NI Policing Board (NIPB); the office of PONI and Probation Board for Northern Ireland (PBNI). More information on NDPBs can be found on the Civil Service Website www.civilservice.gov.uk
