关于自首认定在司法实践中存有许多疑难问题,集中体现在自首主体、自首时间、自首内容三个方面特定情形下的争议。本文指出解决这些问题需从自首制度建构基础上进行分析,且从立法上进行完善。 There are a lot of difficult problems in the judicatory practice about surrendering themselves, which are mainly embodied in the disputes under the special circumstances of the three aspects of surrendering the main body, surrendering time and surrendering contents. This paper points out that the solution to these problems needs to be analyzed from the construction of surrender system, and the legislation should be improved.
