行为暴力与疾病共存的尸检鉴定中,死因有时难以确定。而刑法因果关系是刑法归责的基础,与客观因果律存在差异,故可以通过刑法因果关系规避鉴定的疑难点。本文先简介了刑法因果关系的各种流派,后通过分析三例疑难案件,得出三层次结论:行为暴力足以致死时无需考虑疾病影响;满足条件说公式即可肯定行为需刑法归责,疾病仅为特殊体质因素;在肯定疫学因果关系说前提下,法医鉴定报告仅需写明行为暴力、疾病与死亡相互间一般联系,无需分析特定案件行为暴力或疾病在死亡过程中具体的参与度。 In the autopsy of coexistence of behavioral violence and illness, the cause of death is sometimes difficult to determine. The criminal law causality is the basis of the criminal law imputation, and the objective causality is different, so causal relationship between criminal law can be identified by the difficult to avoid problems. This article first introduces the causal relationship between the various genres of criminal law, after the analysis of three cases of difficult cases, draw three levels of conclusions: behavior violence enough to die without considering the impact of disease; to meet the conditions that the formula can be affirmed the criminal law to be blamed, the disease Only for the special physical factors; affirming the causal relationship between the premise that the forensic identification report need only indicate the general behavior of violence, disease and death, no need to analyze the specific case of violence or disease in the process of death, the specific participation.
