이사의 충실의무(상법 제382조의 3)의 재검토 - 2009년 신탁법 개정안과 관련하여 -

Scholars' opinion has been divided on the issue of the relationship between director's duty of care and duty of loyalty in Korean Commercial Law. Case Law interprets that the duty of loyalty is included in the meaning of duty of care, and Art.382-3 of Commercial Law has no special meaning. Recently the Trust Law Amendment of 2009 clearly enacts the trustee' duty of loyalty that has been admitted only by interpretation. And the Commercial Law Amendment of 2008 tightens up the director's duty of loyalty; to expand the scope of self-dealing that requires the approval of the board of directors, and to introduce the new provision of corporate's business opportunity doctrine. In this circumstances, the writer's opinion is that the director's duty of loyalty should be estimated positively. And in this regard, the writer concentrates on considering why it should be. The concept of duty of loyalty is helpful, both in systematizing the director's various duties and in adjusting the various interests of stakeholders in stock corporations. So the writer's opinion is: There exists a fiduciary relationship between director and the stock corporation same as between trustee and truster, and fiduciary duty which is composed of duty of care and duty of loyalty comes from this relationship. And Art.382② of Commercial Law enacts the provision of director's duty of care, and Art.382-3 thereof enacts the provision of director's duty of loyalty. This paper consists of as follows:Ⅰ. Introduction Ⅱ. Traditional Theory and Case Law on the Meaning of Art.382-3 of Commercial Law Ⅲ. Terminology Ⅳ. Trustee's Duty of Loyalty in the Trust Law Amendment of 2009Ⅴ. Importance of Art.382-3 of Commercial Law Ⅵ. Conclusion
