In the current civil litigation system, the parties play a crucial rolein gathering and submitting evidence. However, in pursuit of maximizingtheir own interests, it is common to observe a phenomenon where theparties may engage in actions such as destruction, concealment, or refusal tosubmit evidence in order to impede the opposing party's proof activities. Theobstruction of proof in litigation constitutes a serious infringement on the rightto sue, hindering the progress and development of the litigation process, andreducing litigation efficiency. The urgent task at hand is to establish explicitlegal provisions to impose severe sanctions on acts of obstructing proof and toprovide judicial remedies for parties who have suffered from such obstruction,in order to uphold the fairness of the litigation process. In judicial practice inChina, prominent types of proof obstruction include cases related to intellectualproperty rights, family disputes, and infringement of trade secrets. These caseshave shown a growing trend of proof obstruction, with diverse methods ofobstruction being employed. However, the study of proof obstruction in China'sacademic community is still in a stage where the connection between theoryand practice is not sufficiently tight. The theoretical research on the proofobstruction system has always been the focus of investigation. It is important for us to shift our focus to bridging the gap between theory and practicefrom an international perspective, emphasizing the role of translating theoryinto practice, and drawing lessons from the experiences of other countries toeffectively apply the logical framework. We need to employ in-depth methodssuch as comparative research to conduct comprehensive studies on the proofobstruction system, and propose reasonable procedural safeguards andremedies.
