From the perspective of normative nature, the first paragraph of Article 33 of the Supervision Law is not a special authorization provision, but a provision of attention. Its main function is to prompt judicial personnel that the supervisory organ has become the legal subject of duty crime investigation, and the evidence materials collected by it can be directly used in criminal procedure. This kind of direct use only gives the preliminary qualification that the supervisory investigation evidence enters the criminal procedure. If the supervisory investigation evidence wants to be the “final evidence”, it must be subject to the evidence examination of the judicial organ. There are two standards for evidence examination: the requirements and standards of evidence in criminal trials with legal effects; the provision of evidence collection in the supervision law.
