行为人既有国家工作人员的身份,又有非国家工作人员的职务身份,其犯罪时究竞利用了何种身份,是实践中的一个难题。在双重身份者利用身份实施的犯罪中,认定其犯罪身份,应以其行为时所从事的活动内容是否属于国家公务作为基本标准,而在具体认定时,则应重点做好以下三项工作:准确把握行为人涉嫌犯罪的行为;明确行为时所从事活动的内容和性质;严格坚持“事实存疑有利于被告”的原则。 It is a difficult problem in practice that the perpetrator not only has the status of national staff, but also has the status of non-state staff. In the crime of using identities by dual identities, the criminal identification should be based on whether the content of the activities engaged in their acts belonged to the state or not as the basic standard. In the concrete identification, the following three tasks should be focused on: Accurately grasping the perpetrator’s criminal behavior; Clarifying the content and nature of the activities engaged in the act; Strictly insisting on the principle that “the facts are in doubt in favor of the defendant.”
