Local justice areas are units in England and Wales established by the Courts Act 2003, replacing and directly based on the previous petty sessional divisions. They have been in existence since 2005. Whilst previously, local justice areas were used to determine which magistrates' courts may hear a particular case, since 1 April 2015, any magistrates' court in England and Wales may hear any case from anywhere in England and Wales. The areas established were identical to the petty sessional divisions. They have since been amended by the merger of South Pembrokeshire and North Pembrokeshire to a single Pembrokeshire local justice area, and the merger of De Maldwyn and Welshpool to a single Montgomeryshire local justice area – this change came into force in 2006, although the magistrates already shared the same courtroom. A further amendment occurred in 2006 when the areas of Shrewsbury, Oswestry and Drayton were combined to become a new area named Shrewsbury and North Shropshire. The areas of Telford and Bridgnorth and South Shropshire were also combined to become a new area named Telford and South Shropshire. A major rearrangement culminated in April 2017, when many local justice areas were amalgamated to leave 75 across England and Wales. Each local justice area was part of a larger courts board area, which replaced the magistrates' courts committee areas with the inauguration of Her Majesty's Courts Service in 2005. Courts boards were abolished in 2012. Local Justice Areas will be abolished once Section 45 of the Judicial Review and Courts Act 2022 is brought into force.
