Section 24 empowers the supervisory authority, where it considers it appropriate or in the public interest, to investigate the possible breach of a prescribed accountancy body's standards by a member. The section contains the necessary powers to facilitate such an investigation by the supervisory authority, including requiring the production of documents, the attendance of relevant persons before the supervisory authority and the power to certify cases where relevant persons have refused to co-operate with an investigation by the supervisory authority to the court, with a view to the court determining the extent to which they should co-operate with the authority. Appropriate appeal mechanisms are also built into the section.
