Ethics in Auditing Practice

Ethics in auditing is not a code of rules but a discipline of judgement. The MIA By-Laws, the IFAC Code of Ethics, and the International Independence Standards all converge on five fundamental principles: integrity, objectivity, professional competence and due care, confidentiality, and professional behaviour. These are not aspirations — they are the conditions under which the audit opinion has value.

Independence is the most visible of these principles and the most frequently tested. The threats to independence are well-categorised: self-interest, self-review, advocacy, familiarity, and intimidation. Each threat demands a safeguard — sometimes a procedural control, sometimes a structural separation, sometimes the refusal of the engagement entirely. When safeguards cannot reduce the threat to an acceptable level, independence is compromised and the engagement must not be accepted or continued.

The hardest ethical decisions are not the clear-cut ones. They are the situations where the right answer is ambiguous, the commercial pressure is real, and the cost of doing the right thing is high. The code provides the framework; the practitioner must supply the courage.

Professional scepticism — an attitude that includes a questioning mind, alertness to conditions which may indicate possible misstatement, and a critical assessment of evidence — is the operational expression of independence. Without it, the audit is a mechanical exercise; with it, the audit is what the public expects it to be.
