Fraud under criminal law is a commonly committed crime, but there are still quite a few doubts as to its application in individual cases. This study will attempt to explain how the legal interest of fraud crime is the right of a person to dispose of one’s property, as well as seek to establish institutional social interaction, i.e. the widely practiced modes of interaction in which people acknowledge the subjectivity of one another, as the standard by which fraud-exported risks may be judged as unacceptable in criminal law, and its applicability to concrete, individual cases. Institutional social interaction can’t be understood by another concept external to itself, but may only be understood within itself. The concrete cases utilized in this study are therefore merely a momentary observation and conception of institutions. Hence, this study aims to stimulate more thought and dialogue on the matter rather than arousing wholesale agreement or disapproval.
