New Mexico Appeals Court overturns a man convicted of driving at .08
because evidence that his blood alcohol was less behind the wheel was
ignored.
Individuals in borderline driving under the influence (DUI) cases in
New Mexico now have a chance of proving their innocence after an Appeals
Court decision released on June 1.
The case involved a Lincoln County man named John Day who was pulled
over because his license plate was not illuminated. His driving did not
exhibit any signs of impairment. When the police officer noticed an open
container of beer in the car, however, he performed a field test and
arrested Day for drunk driving. A breath test conducted 66 minutes after
the stop showed Day was right at the .08 blood alcohol limit. Day later
was convicted in a Lincoln County District Court based on this
evidence.
Because the blood alcohol reading rises over time as alcohol is
absorbed into the bloodstream, Day’s reading may not have accurately
reflected his blood alcohol level at the time he was driving, according
to Doctor Edward Reyes, a pharmacologist who testified for the defense.
The appeals court ruled that it was improper for the state to ignore this
evidence.
“We hold that absent scientific evidence of the alcohol absorption and
elimination processes tied to facts that must be considered in
scientifically evaluating the alcohol absorption rate of a particular
driver, the jury could not have rationally inferred that defendant had a
.08 alcohol content at the time of driving,” Judge Jonathan A. Sutin
wrote for the court in a 3-0 decision.
The judges suggested that a “retrograde extrapolation” should have
been done to estimate Day’s intoxication level at the time he was driving
based on the time of alcohol consumption and other relevant factors. The
judges suggested that the law may need to be changed to ensure a constant
stream of convictions. “The problem of proof also raises the question of
whether a new statute is needed to overcome the difficulty of proof,”
Sutin wrote.
