derivative action n. a lawsuit brought by a corporation shareholder against the directors, management and/or other shareholders of the corporation, for a failure by management. In effect, the suing shareholder claims to be acting on behalf of the corporation, because the directors and management are failing to exercise their authority for the benefit of the company and all of its shareholders. This type of suit often arises when there is fraud, mismanagement, self-dealing and/or dishonesty which are being ignored by officers and the Board of Directors of a corporation.
