In the jurisdiction of England and Wales, a Multi-Agency Public Protection Arrangement (MAPPA) is an arrangement for the "responsible authorities" tasked with the management of registered sex offenders, violent and other types of sexual offenders, and offenders who pose a serious risk of harm to the public. The "responsible authorities" of the MAPPA include the National Probation Service, HM Prison Service and England and Wales Police Forces. MAPPA is coordinated and supported nationally by the Public Protection Unit within the National Offender Management Service. MAPPA was introduced by the Criminal Justice and Court Services Act 2000 and was strengthened under the Criminal Justice Act 2003.
Following the Criminal Justice Act 2003, Lay Advisors have been introduced to sit on Strategic Management Boards (SMBs) who have the strategic oversight of MAPPA. These are members of the public who have been selected to help with the development and monitoring of Multi-Agency Public Protection Arrangements and aim to boost public confidence in the arrangements. There should be two Lay Advisers on each SMB in England and Wales, a total of 84 nationally.
The legislation requires a three-stage process for managing dangerous offenders. First, these three agencies in conjunction with partner agencies, such as social services and health agencies, need to identify three types of offender living in their area:
An offender cannot be in more than one MAPPA Category, and if multiple offences are committed, they will default to the lowest number category. For instance, if an offender committed an attempted murder, but also committed a sexual assault, they would be a Category 1 offender rather than a Category 2 for the duration of their Sex Offender Registration. Following the completion of their registration, if they were still under Probation supervision/licence then they would become a Category 2 offender. If the supervision/licence had expired, then it would be up to the local area MAPPA if they qualify for Category 3 status.
The legislation then requires that the agencies conduct a formal risk assessment of each offender and allocate them to a tier of multi-agency management — known as level one, two or three.
