99.Under subsections (1) to (3) the Scottish Ministers may give directions to local authorities about their functions under the Act. Under subsections (4) and (5) Ministers may, if they so direct, exercise local authority functions under Parts 3 and 4 of the Act in place of that local authority. Ministers could, for example, use this provision to compel a local authority to repair one of its own buildings (e.g. the city chambers) where it refuses to do so.
