232.Section 56 allows the Audit Commission to carry out studies relating to health care or English NHS bodies (under sections 54 and 55) on the Commission’s behalf, with the Commission’s agreement. Where a matter could be considered to fall within the remit of both organisations, as is the case for studies regarding economy, efficiency, and effectiveness in relation to adult social care, subsection (5) directs them to have regard to any guidance issued by the Secretary of State as to who should carry them out.
