醉驾案件酒精检测结果边缘值问题研究

Research on the Marginal Value of Alcohol Test Results in Drunk Driving Cases

对于科学证据的边缘值在案件处理中的特殊意义,我国理论界与实务界都缺乏关注。在醉驾案件中,如何对待酒精检测结果的边缘值决定着驾驶人员罪与非罪的不同命运。正视酒精检测结果的边缘值问题并引入清醒测试,可以更准确地识别驾驶人是否处于醉酒状态。这有助于压缩犯罪圈的不当扩张、减少冤假错案及促进司法的精密化。酒精检测结果的边缘值可分为绝对边缘值与相对边缘值。当酒精检测结果的落值区间不同时,应对案件作分类处理。边缘值问题在科学证据中普遍存在。当刑事科学证据检测结果处于边缘值区间时,一是要弱化科学证据的证明力,一般应有其他证据进行补强;二是应以有利于犯罪嫌疑人的方法运用科学证据。

There is a lack of attention in both theoretical and practical circles in China to the special significance of the boundary value of scientific evidence in case processing.How to deal with the boundary value of alcohol testing results determines the different fates of drivers'crime and non crime in many drunk driving cases.Facing the boundary value issue of alcohol detection and introducing sobriety testing can more accurately identify whether drivers are intoxicated.This helps to compress the improper expansion of the criminal circle,reduce false and erroneous cases,and promote the precision of the judiciary.The boundary value of alcohol testing results can be divided into absolute boundary value and relative boundary value.When the alcohol testing results are located in different intervals,the related cases should be classified.Boundary value problems are common in scientific evidence.When the detection results of criminal science evidence are in the edge value range,the application of scientific evidence should adhere to two directions:Firstly,the probative force of scientific evidence was weakened so that other evidence is generally necessary to serengthen the force;Secondly,scientific evidence should be used in a way that benefits the suspect.
