A unique overview of the main criminal justice institutions across the three UK jurisdictions of Scotland, Northern Ireland, and the combined jurisdiction of England and Wales.

• How are the main UK criminal justice institutions organised?

• How did they develop over time into their current form?

• How are they held to account?

• How can ordinary citizens challenge them and influence their work?

These are the main questions covered in Criminal justice systems in the UK.

No gold standard

Across the UK, there is no single, UK-wide criminal justice model; no ‘gold standard’ arrangement. Three criminal justice jurisdictions, with different histories, structures and operations, cover the United Kingdom: the combined jurisdiction of England and Wales, and the separate jurisdictions of Scotland, and Northern Ireland.

The diverse UK criminal justice arrangements, the result of distinctive histories, cultures and politics, offer a variety of operational and reform options.

Criminal justice systems in the UK takes the varieties of criminal justice across the UK as its starting point, drawing out similarities, and identifying contrasting arrangements across the UK's nations and regions.

Criminal justice systems are under constant scrutiny. Calls for improvement and change are never far away. This report outlines a number of key mechanisms currently available in the different jurisdictions of the United Kingdom to hold these institutions to account and to press for change and reform.

Report structure

Criminal justice systems in the UK is divided into four main chapters, covering the police, prosecution, courts and prisons. Each chapter examines the main mechanisms for accountability and change:

• Governance

• Inspection

• Complaints

• Citizen accountability

Each chapter examines how these four main mechanisms operate across the three UK jurisdictions of England and Wales, Scotland and Northern Ireland.
