    Objective To investigate the characteristics of cases which exaggerated or disguised vision decrease during forensic medical appraisal after eye injury, summarizing the matters for attention in forensic medical appraisal practice. Methods Cases being identified as exaggerated or disguised vision decrease, from 2019 to 2022, were collected. The nature of the cases, general condition, injury objects, injury types, visual chart vision and examination results were analyzed statistically. Results 11 cases out of 39 cases had disguised binocular vision disorder. The type of injury was mostly eye adnexal injury, and the mode of injury was mostly boxing injury. The range of impaired visual acuity in disguise was between 0.05 and 0.4. Conclusion In the practice of eye injury assessment, the expert opinions can not only rely on the diagnosis of medical records and the self-reported visual acuity of the patients. It is necessary to take the degree of eye injury into consideration, and analyze objectively the correlation between visual impairment and trauma.

    Study on the Reliability of Forensic Science / Forensic Appraisal Opinions
    WANG Xu, ZHANG Mingrui,
    Chinese Journal of Forensic Sciences    2023, 0 (3): 1-8.   DOI: 10.3969/j.issn.1671-2072.2023.03.001

    In order to adapt to various investigation and evidence application purposes, forensic science/forensic appraisal opinions should have the characteristics of reliability and validity. This article begins with the question of the reliability of forensic science, and systematically sorts out the related concepts of forensic science. Taking the court science report of the US President’s Council of Advisors on Science and Technology in criminal justice as a reference, the central idea of the report is the reliability of appraisal opinions such as repeatability, reproducibility, and accuracy. The scientific standards for the reliability of forensic appraisal methods in the report are also extracted, which include foundational validity and validity as applied. The former includes two main elements: the need for reproducible and consistent appraisal procedures, and the need to empirically study the false positive rate and sensitivity. Based on the above review and analysis, it is proposed that the construction of reliability of the current appraisal opinions should include: ensuring the universal acceptance of scientific theories/methods applied by the forensic science community; ensuring the scientific validity of the appraisal method itself; setting requirements for the eligibility of appraisal personnel; preventing the influence of motive bias and cognitive bias on reliability; and strengthening the internal verification construction of forensic appraisal and comprehensively enhancing the quality control of forensic science/forensic appraisal to ensure the reliability of appraisal opinions.

    The Review Principles and Keypoints of Drunk Driving Dangerous Driving Appraisal
    LUO Jing
    Chinese Journal of Forensic Sciences    2024, 0 (4): 75-80.   DOI: 10.3969/j.issn.1671-2072.2024.04.010
    Abstract274)      PDF(pc) (1277KB)(585)       Save
     In recent years, with the increasing number of dangerous driving cases, the number of acquittals has also increased year by year. Among them, some of the acquittals were caused by the problem of expert opinion. In practice, the main body of the expert opinion is not qualified, the inspection is not standardized, the source of the sample is not legal, the report is overtime, the application of the identification standard is wrong, etc., often become the reason why the expert opinion is not adopted in the acquittal, which seriously affects the quality and efficiency of the processing of such cases. Therefore, it is particularly important to grasp the principles of review of expert opinions, and do a good job in the “penetrating” review of expert opinions from the aspects of source of samples, selection of blood collection vessels and disinfection reagents, qualification of appraisers and appraisal institutions, appraisal standards and methods, etc.

    With the rapid development of forensic science in China in recent years, a number of identification standards and technical specifications have been updated. However, due to the uniqueness of Chinese Judicial system, the application of relevant standards still causes confusions. From the aspect of applicability, this paper introduced the relevant standards of handwriting identification in Europe and the United States, and compared them with the standards of forensic handwriting identification in China. These identification standards formulated by different organizations are different in terms of basic structure, content, conclusion expression and so on. On the other hand, even domestic handwriting identification standards also varied in content and system. The causes of the differences were analyzed in this paper. Based on the current situation of domestic handwriting identification, suggestions were put forward to provide reference to the forensic practice, as well as the future modification of handwriting identification standards.

    The reliability of forensic expertise is an important dimension of the credibility of evidence. Compared with the threshold of evidence entry of relevance, reliability is the main indication of the quality of forensic evidence, and unreliable forensic expertise becomes the source of the error of fact-finding. We think there are three main ways to enhance the reliability of forensic expertise: The first is to strengthen the quality management of forensic examination process, including attaching importance to the role of pre-evaluation procedure, establishing the traceability mechanism of the materials, and maintaining the “neutrality” of forensic institutions and forensic practitioners. The second is to improve the production and cross-examination of the forensic expertise in court, including the proof of the identity or authenticity of materials by identification or authentication witnesses with their personal knowledge, and forensic practitioners presenting their forensic expertise, the cross-examination of the forensic expertise by lawyers and expert-assistants. The third is the deliberation of the “foundational validity” and the “validity as applied” of the forensic expertise by judges. While reviewing the “foundational validity”, the key is to grasp the “error rate” and “forensic technology standard”. Besides, we explore the quantitative control idea of the likelihood ratio in the whole process of forensic examination.

    The Decision on the Management of Forensic Appraisal (hereinafter referred to as the Decision) passed by the Standing Committee of the National People’s Congress in 2005, as the only specialized law in the field of forensic appraisal, has promulgated and implemented a unified forensic appraisal management system. However, with the progress of the rule of law and many new situations in the field of forensic appraisal, the legislation of forensic appraisal has once again become the focus of attention. The legislation of forensic appraisal is not only facing with the old problems left over from the formulation of the Decision, but also with new problems derived from the implementation of the Decision. On the basis of the operation of the existing system, it is necessary to conduct in-depth research on the major issues involved in the legislation of forensic appraisal, respectively from the macro, meso and micro levels, so as to gradually form a systematic, forward-looking and relatively mature legislative consensus.

    Rethinking and Solution to the Practice of “Substituting Trial by Appraisal”
    XI Fei
    Chinese Journal of Forensic Sciences    2023, 0 (4): 10-18.   DOI: 10.3969/j.issn.1671-2072.2023.04.002

    The amended Several Regulations on Evidence in Civil Litigation issued by the Supreme People’s Court in 2019 have not resolved the problem of “substituting trial by appraisal” in judicial practice. The constraints on the behaviors of judges are ignored, and excessive regulations on the behaviors of forensic appraisal institutions and litigants are set. As the dominant person in a lawsuit, a judge’s failure to review the appraisal matters, non-participation in the appraisal process and the focus on the form review of the appraisal opinions are the fundamental reasons causing the result of “substituting trial by appraisal”. The corresponding path and method should be followed by the involvement of judicial power in the appraisal process. To be specific, the identification of the facts should be taken as the center when the appraisal is initiated, and the parties shall undertake the burden of proof of “minimum evidence”, while the judge should accurately position the “specific issues” and determine the appraisal items through “party debate and functional review”. At the time of carrying out the appraisal, it is necessary to control the appraisal materials and the qualifications of appraisers. When reviewing the appraisal opinions, it should be considered whether the appraisal opinions and appraisal items, appraisal materials and appraisal basis, appraisal basis and appraisal reason conform to one another.

    Introspection and Reconstruction of Self-commissioned Appraisal Opinion
    QIAO Fang’e
    Chinese Journal of Forensic Sciences    2024, 0 (1): 82-90.   DOI: 10.3969/j.issn.1671-2072.2024.01.012

    Although self-commissioned appraisal widely exists in our country, the current legislation does not clearly indicate its nature, the definition of  “quasi private document certificate” in cross-examination rules reserves the room for academic discussion. In the theoretical circle, there are opposing views on the nature of the opinion issued by a self-commissioned appraiser: is it factual statement or statutory evidence, where the latter has the different views as expert opinion, witness testimony and documentary evidence. In practice, there are some errors in handling the problem of self-entrusted appraisal, such as simplification of judgment view, avoidance of making clear its nature, misinterpretation of provisions and abuse of burden of proof. Based on the re-thinking and examination of theoretical differences and errors in judgment, this paper argues that self-commissioned appraisal has the dual attributes of fact assertion and evidence, and the latter is more significant. Furthermore, it is argued that opinions issued by self-commissioned appraisal should not be regarded as statutory appraisal opinions in principle, but can be converted by exception upon the consent of the parties. In the absence of consent from the parties, it may be permitted to use similar appraisal opinions for cross-examination certification. At the same time, in order to effectively avoid errors in judgment, regulations regarding burden of proof, conditions for application of appraisal, the adoption of written opinions and other issues relating to self-entrusted appraisal should be comprehensively improved, so as to better understand and apply Article 41 of the 2019 revised Several Provisions of the Supreme People's Court on Evidence in Civil Litigation on the basis of systematic interpretation.

    Forensic appraisal involves not only litigation activities, but also administrative law enforcement, supervision, arbitration, mediation and other activities in many fields. The latter activities need forensic appraisal to provide forensic evidence, and also make connection machanism with appraisal law. The forensic legislation should be positioned from the perspective of national development strategy, embody the function of public legal service, and satisfy the real demands of various dispute settlement activities from multidimensional perspective. It is expected to emphasize the nature of comprehensive law embedding organic, administrative and coordinating law, and to guarantee that the legislative arrangement can provide scientific evidence on the basis of due process. Therefore, it can play the role of finding the true scientific evidence and develop the assistant function of experts in maintaining the right of parties.

    Forensic appraisal as an expert identification activity and opinion evidence in the judiciary, has multifaceted characteristics. To ensure its objectivity, impartiality, scientificity, and credibility, different laws are needed to regulate it from different aspects. There are different types of dual structures in these laws, including the subject duality of “producers” and “users” in forensic appraisal legal relationships, the administrative management of forensic appraisal laws and the duality of forensic procedures, and the duality of forensic appraisal in litigation procedures. Due to differences in functions and different regulations on forensic appraisal, different laws are prone to conflicts, so it is necessary to coordinate and solve such problems. By analyzing the dual structure of forensic appraisal law, based on the analysis of the problem and its causes, the principles for solving the coordination problem of the dual structure are established, and reference ideas are proposed for resolving the legal problems of the dual structure.

    Restatement and Review Path of the Reliability of Uncertain Appraisal Opinions
    GUO Hua
    Chinese Journal of Forensic Sciences    2023, 0 (3): 21-28.   DOI: 10.3969/j.issn.1671-2072.2023.03.003
    Abstract208)      PDF(pc) (1081KB)(1007)       Save
    The reliability of appraisal opinions is closely related to whether they can repeatedly obtain consistent results. Uncertain appraisal opinions, as a normal phenomenon of appraisal results, have reliability if the uncertain results can be repeated or consistent during re-appraisal, meeting the requirements of scientific appraisal. The reliability of the confirmation of uncertain appraisal opinions with positive and negative tendencies varies depending on the direction of the results, which to some extent affects the admissibility of the appraisal opinions as evidence. However, the method of cross-examination through falsification can enhance or weaken its credibility and obtain the result of validity. If the appraisal opinion cannot be falsified and has scientific validity, it can play a role in determining the facts of the case. When reviewing uncertain appraial opinions, opinion that does not conform to science should be excluded first, and then review opinions reliability. The consistency of repetition is checked through program control to ensure the scientificity of the appraisal. Judicial practice should be vigilant in excluding all uncertain appraisal opinions. And theoretically, it is also necessary to abandon the bias that all uncertain appraisal opinions are unreliable, and return them to the essence of scientific appraisal and their inherent functions.
