All criminal trials include the right of the accused to receive a fair trial. A man charged with drunk driving got his conviction overturned by the Louisiana Court of Appeal because the trial he received was not a fair one. The recent ruling stated that, when the trial court allowed the state to use a partial and incomplete breath analysis test result as proof that the driver had a blood alcohol content above .08 and had violated the law, it allowed the jury to be improperly prejudiced and necessitated a reversal of the conviction.
In May 2010, John Wayne Farley was involved in an auto accident for which he was at fault. Shreveport Police Police arrested Farley for driving drunk. During a breath test, Farley began blowing on the Intoxilyzer device but stopped breathing into the device before it could complete its analysis. According to the officer overseeing the test, the device’s display gave a reading of .17 prior to the driver’s discontinuation of the test.
At Farley’s trial (4th offense DWI), the state offered evidence from the officer regarding the .17 reading. The state used this evidence as proof of that the driver had a blood alcohol content above the legal limit of .08 and that the man was guilty of violating La. R.S. 14.98. The prosecutor told the jury several times about the officer’s observation of the .17 reading and reminded them that a .17 blood alcohol content was more than twice the legal limit.
