The double derivative suit has been developed in case law in the U.S.A. in the pursuit of justice. In the U.S.A., this kind of suit is inferred from a single derivative suit and extends its qualification for a plaintiff to a shareholder of its parent corporation. The 2006 revision draft of the Korean Commercial Code(K.C.C.) introduces a double derivative suit which is recognized in common law jurisdiction. The double derivative suit can protect minor shareholders of parent corporation from harmful management of fiduciaries of subsidiary. However the most business circles and corporations in Korea are opposed to introducing this kind of derivative suit in the K.C.C. on the ground that will obviously shrink activities of corporations. But it is very important to recognize that the derivative proceeding of shareholders is an equitable remedy. This means that it is only a extraordinary and exceptional device to help the shareholders. In consequence, it is very difficult and so at the same time meaningless to codify the pre-requisites of this suit. I think the best way to introduce and to develop it is through a case law.
