A director must act in accordance with the company's constitution and only exercise powers for the purposes for which they are conferred. The general duties in sections 171 to 177 are owed to the company, apply to shadow directors where the corresponding common law rules apply, and are interpreted and applied in the same way as the common law rules and equitable principles they codify (section 170). Breach has the civil consequences the common law provides (section 178).
