Meaning
Procedural representatives possessing specialized technical knowledge assist litigants in cross-examining expert appraisers and clarifying complex technical matters during court proceedings in China. The appointment of a 专家辅助人 is authorized under the Civil Procedure Law of the People’s Republic of China and relevant judicial interpretations to address technical asymmetry in complex litigation. These technical assistants act on behalf of the appointing party rather than as independent court officers, providing technical explanations, challenging judicial appraisal reports and questioning technical investigators.
Their statements in court are treated as representations of the appointing party.
Procedural Role
Appointing parties submit applications to the hearing tribunal prior to court sessions to secure permission for technical advisors to appear.
Cross Examination
During trial proceedings, these specialized representatives directly question court-appointed appraisal experts regarding testing methodologies, laboratory equipment calibration and analytical conclusions. A 专家辅助人 exposes technical contradictions in adverse expert reports and presents alternative technical interpretations supported by peer-reviewed literature or laboratory testing. The court permits these technical advisors to address judges directly, translating intricate engineering concepts, chemical formulas or software architectures into clear factual arguments.
This direct participation balances the technical capabilities of foreign rights holders and domestic defendants during high-stakes patent and trade secret litigation.
Judicial Evaluation
Statements provided by expert assistants do not constitute independent expert opinion evidence under Chinese civil procedure. Judges treat these submissions as factual allegations made by the party that retained the advisor, requiring corroboration through documentary evidence, physical samples or judicial appraisal reports. Courts evaluate the credibility of technical arguments presented by a 专家辅助人 based on logical consistency and alignment with verified physical evidence rather than formal expert witness status.
