“举证责任倒置”在医疗侵权诉讼中的实施虽然缓解了患者举证的困难,同时也在一定程度上导致了诉讼中民事责任的不当扩张。笔者对按照现行法律规定医疗机构所承担的举证责任从法理学、证据学、医学科学的角度进行分析,阐述了在医疗侵权诉讼中由专家举证来辅助“举证责任倒置”完成的观点。 Although the implementation of medical tort lawsuit alleviates the difficulty of patient proof, it also leads to the improper expansion of civil liability in the litigation to a certain extent. Based on the jurisprudence, evidence theory and medical science, the author analyzes the burden of proof that the medical institution undertakes in accordance with the existing laws and expounds the viewpoints that the expert evidences support the completion of the “reversal of the burden of proof” in medical tort litigation.
