| IOUs as proof of debts of important documents pervasive in economic activity among people.The bills as an object to illegal activities often occur. But in the nature of the bills, bills as to whether the object offense constitutes a crime, the issue of what constitutes crime, the criminal law field there are still many different views.I start from the nature of the bills, bills demonstrate the dual attributes of both documents and property rights, and similar concepts are compared with the distinction. As a basis to explore the illegally acquired bills violated legal interests of the specific circumstances of illegally acquired bills behavior and subsequent behavior may arise from the discussion of the classification,especially for implementation of the above acts of the perpetrator and the purpose of this bill such cases the specific positioning analysis, practice for resolving disputes involving bills cases appear to make qualitative judgments.This paper argues that the IOUs can be evaluated as property, but as a rights certificate of property interests. Because IOUs can be evaluated as property, so as a property crime offenses object does not violate the principle of legality. Illegally obtaining IOUs caused the victim infringement is a kind of danger that will only achieve evidenced property interests by IOUs to make dangerous into actual harm results. The indebtedness of the debtor’s behavior should not be evaluated as a crime, but the debtor illegally acquired IOUs behavior should be evaluated as a crime. Illegal acquisition of IOU’s behavior can be for a variety of purposes, for different purposes IOUs understanding is not the same, will affect the behavior of illegally acquired IOUs conviction and sentencing. |
