The Code of Best Practice produced by the Cadbury Committee on the Financial Aspects of Corporate Governance may be viewed as an ethical code in that it prescribes standards of board behaviour. The Code’s specific recommendations with regard to audit committees appear to offer a practical mechanism for the promotion of ethical behaviour through the inhibition of potentially unethical influences exerted by executive directors over external auditors. The rationale for these recommendations centres on the independence of audit committee members, implying (...) that independence is a prerequisite for ethical behaviour. This paper questions the assumptions regarding the role of independence through an exploration of conceptions of independence held by individuals involved in the activities of audit committees in major UK public limited companies. It suggests that audit committees may have an unarticulated role in providing an arena for the display of independence by the participants. This display forms a part of the ceremonial performance which builds confidence in corporate governance mechanisms. (shrink)
