Part 1 of the Local Government and Public Involvement in Health Act 2007 (c. 28) (“the 2007 Act”) provides for structural and boundary changes in relation to local government areas in England. Structural change is a change from two-tier local government (a county council and district councils) in an area to a single tier of local government. There is a single tier of local government for an area if there is either a county council and no district councils for that area, or a district council and no county council for that area (section 1(2) of the 2007 Act).
