[Does the highest judicial ordinance for a new limit value for absolute driving incapacity (BGH 4 StR 297/90, Beschl. v. 28 June 1990) allow unequal treatment of alcohol intoxicated drivers?].Blutalkohol. 1991 Jul; 28(4):252-5.B
The jurisdiction in the BRD knows a threshold value of the blood alcohol concentration from which on the actual absolute driving unfitness without any further evidence will be assumed. This threshold value has been lowered by the highest german criminal court (BGH) from so far 1.3% to now 1.1 g%. As the determination of the alcohol content takes place in two different procedures as a mean value out of four or five single values, the highest court orders a dispersion control--the standard deviation from 0.03 g% or 0.04 g%. The authors proof that therefore a dissimilar treatment of motor traffic participants under the influence of alcohol may be possible. The reason is to be traced in the different distributions of a single values around the mean value and in the incorrect application of the standard deviation.
