The forensic analyst who assessed Judge Nkola Motata's blood alcohol content admitted ignoring scientific standards when analysing his blood samples.
He said this yesterday during cross-examination by defence advocate Danie Dorfling in the Johannesburg magistrate's court.
"Do you agree with me that what you did, implementing the 25 degrees Celsius, you ignored the Counsel for Scientific Industrial Research standards?" Dorfling asked Logan Govender.
In response, Govender said: "That's correct."
By using the wrong temperature, wrong density of water, and wrong volume of liquid, Govender admitted he arrived at the wrong formula, which impacted on the blood alcohol percentages he got.
Giving evidence in court in November last year, he testified that the sample he analysed recorded a concentration of alcohol in the blood of 0.2g per 100ml.
The legal limit is 0.05g per 100ml. Yesterday he said a mix-up of files in the Johannesburg forensic laboratory was to blame as the "wrong batch number was added to Motata's certificate".
The trial continues. - Sapa
