Article 35 of the Regulations on the Prevention and Handling of Medical Disputes establishes the institutional framework for legal experts'' participation in medical damage appraisal, yet it lacks clear provisions on core elements such as their role positioning, scope of duties, and applicable scenarios. In medical damage appraisal, legal experts can play a positive role in procedural scrutiny, normative guidance, theoretical clarification, and enhancement of public credibility. Regarding applicable scenarios, four categories of cases particularly require the intervention of legal experts: disputes over informed consent, improper fulfillment of administrative norms, disputes involving multiple parties, and difficulties in legal interpretation. To translate the participation of legal experts from institutional design into practical operation, differentiated access standards should be explored at the expert database construction stage, priority application rules for the four categories of cases should be clarified through working guidelines at the referral stage, and the review obligations and procedural responsibilities of appraisal institutions should be strengthened at the withdrawal stage to safeguard expert neutrality. The deeper value of legal experts'' participation lies in promoting medical damage appraisal from a purely medical judgment toward a collaborative dialogue between medicine and law, thereby endowing appraisal opinions with both factual foundation and legal character.
