In civil litigation, the judgment of some specialized issues relies on appraisal opinions, but in litigation practice, judges and evaluators have differences on the clarity of appraisal opinions. The Several Provisions of the Supreme People’s Court on Evidence in Civil Proceedings and the Provisions on Several Issues Concerning the Entrustment of Appraisal Review Work in Civil Litigation by People’s Courts promulgated by the people’s courts both provide for the clarity of appraisal opinions. Based on these two provisions, this paper discusses the reasonableness of uncertainty appraisal opinions and the understanding of “uncertainty” and “unclear” in the two provisions from the perspective of judicial appraisal, and briefly analyzes the reasons for the conflict between judges and evaluators on the clarity of appraisal opinions and gives corresponding solutions.
