At general law breach of the duties to avoid conflicts and profits (the conflicts and profits rules), as fiduciary duties, can be excused or authorized by the company as beneficiary of the duty. This can be done by approval of the company’s shareholders (usually in general meeting) or by provision in the company’s constitution (allowing disclosure to, and authorization by, the other directors). There are, however, limits placed on such authorization or ratification. The first part of this chapter discusses these limitations. It then discusses relevant statutory provisions in each of the jurisdictions, with a key focus on sections 175, 180, 239, and 232 of the Companies Act 2006 (UK). This includes more detailed discussion of the authorization provisions in sections 175(5) and (6), which are notably absent from section 176. The complex issue of ratification of breach of statutory duty in Australia is also canvassed. This limitation, which does not apply in the UK, renders a number of aspects of directors’ duties problematic. This includes attempts by companies to adopt more stakeholder-friendly approaches.
