Abstract
For the theory of the duty to obey the law. its introductory discussion is as important as its main discussion. In order to bring out the importance and role of theory of the duty to obey the law. we cannot avoid examining its practical significance as well as its theoretical specificity. Here I propose to focus not only on the traditional problem of 'evil law' but also on the problem of 'doubtful law'. Each provides the means to overcome the skepticism about the importance (or, theoretical specificity) of the theory of the duty to obey the law. The former, 'evil law' approach have pointed out that the concept of law's content-independent morality - legality, or L. L. Fuller's 'inner morality of law' - is the key to establish the general duty to obey the law. Besides, the latter, 'doubtful law' approach opens up the perspectives to a new domain of inquiry on the conditions of subjects who are expected to obey and respect their law that is, the conditions of citizenship or law-abiding morality.
