About the CJS Spine

The CJS Spine is a shared set of capabilities that will enable secure, efficient and trusted flows of data across the CJS. It provides the foundations that allow organisations to work together effectively and deliver a seamless end-to-end service.

The CJS Spine will provide:

• A single view of a person, enabling us to reliably identify the same individual, whether they are a defendant, offender, victim or witness, so the right information follows them through the system.

• Connected systemsacross policing, courts, prisons, probation and victim services that can exchange information quickly and securely so it’s available at the point of need.

• High-quality, trusted data that stays that way, supported by clear standards, governance and provenance so confidence is maintained as data flows across organisations and over time.

Together, these foundations support faster, fairer and more joined-up justice. They enable better decision-making, reduce unnecessary duplication, and create the conditions for transformation through digital, data and AI.

The CJS Spine will play a critical role in enabling the Ministry of Justice’s strategic priorities, including protecting the public, reducing reoffending and ensuring swifter justice for defendants and victims through a modern and efficient criminal courts system.

This is an opportunity to work on a major, cross-system capability that will have a lasting impact on how the criminal justice system operates.
