醉驾犯罪血液酒精含量鉴定证据客观性与合法性之判断

The Verdict about Objectivity and Legality of Blood Alcohol Concentration Testimony in Drunk Driving Criminal Case

我国醉驾案的立案标准是驾驶人员的血液中酒精含量值,血液酒精含量鉴定意见由此成为醉驾案最重要的定罪证据。血液酒精含量鉴定证据证明力只有经过排除合理怀疑之后才能确定。如果在血液酒精含量鉴定意见的形成过程中,遵循了鉴定证据取得所应遵循的必要性、中立性、专门性等原则,且其中不存在无法排除的怀疑时,其客观性即可得到证明。基于驾驶权是一种法律许可的特别权利而非自然权利的观念,在驾驶人员拒不配合查验血液酒精含量值的情况下,警察可以基于合理怀疑而采取必要的强制手段,例如强制截停与强制测试等。采取类似强制手段取得的证据,其合法性不存在疑问。当血液酒精含量鉴定意见的客观性与合法性存疑时,宜按照《刑事诉讼法》中的无罪推定原则,对驾驶人员不作犯罪处理。

In our country,the only standard for criminal registration of DUI is the number value of blood alcohol concentration.So,the expert conclusion of blood alcohol concentration is the most important evidence for the DUI prosecution and conviction.The expert testimony about blood alcohol concentration should follow the necessity,objectivity and technicality principles,and it can not be used as the evidence in trial until proven it beyond a reasonable doubt. The driving right is legal right granted rather than natural right,therefore,based on the reasonable doubt,the police can take some compulsory measures,such as mandatory stopping and testing,to obtain the evidence,when the driver refuses the test of blood alcohol concentration. According to the doctrine of the presumption of innocence,if there is any doubt in the objectivity and legality of the blood alcohol concentration expert testimony,the driver could be found no guilty.
