Research on the Challenges and Optimization Path of Criminal Evidence Standards

The criminal evidence standard is a judicial tool established to implement the provisions of criminal law and resolve the issue of evidence deficiency. Its core concept involves setting minimum requirements for the quantity of evidence required for conviction and sentencing in relation to specific crimes, ensuring the evidence meets a threshold of usability. Scholars argue that evidence stand-ards should highlight the fundamental set of evidence required for convic-tion and sentencing, addressing the frequent issues of insufficient evidence, which may result in non-approval of arrests or non-prosecution. The current stand-ards established by local authorities are flawed in terms of their legal ba-sis, con-tent, and application methods, such as inconsistent legal foundations, overly simplistic content, or overly rigid or lenient enforcement. To resolve these is-sues, evidence standards should be based on the elements of crimes as defined by criminal law, and comprehensive evidence collection checklists should be jointly developed for each crime. These lists should be precise and inclusive. The application of these standards should strike a balance between normative rigid-ity and flexibility, allowing necessary annotations and adjust-ments based on specific case conditions, thereby improving the quality and effi-ciency of crimi-nal case processing.
