Apart from the statutory duties of the directors, there are fiduciary duties and the duty of care that is imposed on the directors of companies. Directors have always been considered as fiduciaries, who has accepted to act for another under the circumstances that result in a relationship which involves trust and confidence. As a result, the directors of companies are subject to related obligations that have been derived from the relationship of trust (Bristol and West Building Society v Mothew  Ch1). It is also important that the directors act in good faith and in the best interests of the person whom the present, which in this case is their company and it is also requires that they should not abuse the trust placed on them. At the same time, the duty of care and skill has also grown and tries to deal with the specific implications of the position of a director in a limited company (Prudential Assurance Co Ltd v. Newman Industries Ltd (No.2) 1982). The reason is that in such a case, the directors have been given the responsibility to run a business by the shareholders. Therefore, the shareholders are directly interested in the degree of care and skill of the directors with which they manage the business of the company.
However, apart from these duties, there are statutory duties of the directors also. The common law duties of the directors of companies have been categorized by the Companies Act, 2006. In this way, Ss 170 to 177 of the Companies Act are the eight sections of this legislation that are collectively referred to as the statement of general duties and establish the common law instructions into summarizing statements. Although, most of these duties are on expected lines, however certain important innovations are also present in these sections. Before the implementation of the Companies Act, the law related with directors’ duties was not clear in some aspects. The response to this was the code of Directors’ duties that is present in the Companies Act. In this regard, it needs to be noted that the code of Directors’ duties applies to all the companies.
