Disciplinary processes and tribunals
AAT investigates complaints of misconduct against our members in our mission to protect the public, maintain confidence in the accountancy profession and uphold the high standards of professional and ethical behaviour we expect from our membership. Depending on the circumstances, we may resolve cases informally or where there is evidence of misconduct we may investigate in accordance with our Disciplinary Regulations.
We define misconduct as "a member committing any act or omission that falls short of the standards reasonably expected, including but not limited to those matters listed in the Code of Professional Ethics, which brings, or is likely to bring, discredit to the member, the accountancy profession, or AAT".
A disciplinary investigation may result in sanctions, including monetary fines, being imposed to act as both a warning to the member to remedy their behaviour moving forward but also to deter other members, and our supervised firms, from conducting themselves in the same way. Sanctions are not intended to be punitive although may have a punitive effect.
We investigate complaints we receive in accordance with the Professional Standards Handbook, which is available on request.
