Whether the machine used to administer your breath test was properly certified could make or break the state’s case against you. Illinois regulations set forth several parameters and guidelines the state must comply with to ensure that any machine used to administer a blood or breath test is accurate. If the machine used to administer a breath or blood test was not properly calibrated or tested, any results from the test should arguably be precluded as their accuracy cannot be verified. When it is revealed that the state cannot prove a machine used to administer chemical testing to DUI suspects is accurate, it often affects more than one case and the effects can be far-reaching.

Recently, in State v. Cassidy, the New Jersey Supreme Court ruled that any results from machines that were not properly calibrated for several years were inadmissible, and ordered the state to notify all affected defendants so they could seek appropriate relief. It is estimated that over 20,0000 convictions will be affected by the Cassidy decision, arguably making it one of the most substantial rulings in favor of DUI defendants in recent times. If you are charged with a DUI you should retain an experienced Illinois DUI to attorney analyze the accuracy of any evidence that may be used against you.

New Jersey Supreme Court Ruling

Reportedly, the police officer in charge of calibrating the breath test machines for several New Jersey counties and ensuring that the machines were accurate failed to take a required step in the process, potentially affecting over 20,0000 breath test results. In State v. Cassidy, the Supreme Court of New Jersey analyzed whether the failure to perform all the tests needed to ensure the accuracy of the machines called into question the reliability of the tests.

Pursuant to Georgia law, a trial judge may decide whether a procedure in question has reached a stage of scientific certainty. The trial court makes this determination based on evidence presented to it during trial, or based on exhibits, treatises, or cases from other jurisdictions. The trial court ultimately decides based on the evidence available to him rather than by calculating the consensus in the scientific community. This issue came up before the Georgia Supreme Court this fall in the context of a DUI appeal. It could play a role in Illinois DUI proceedings at some time as well.

Following a jury trial, a Georgia woman was convicted of DUI and possession of an open container. She appealed the DUI. The appeals court affirmed, and the Georgia Supreme Court granted certiorari to consider whether the intermediate court erred in holding that the trial court properly admitted the police officer’s testimony correlating her horizontal gaze nystagmus (HGN) test results with her blood alcohol content (BAC). The Georgia Supreme Court reversed her conviction because the testimony lacked a sufficient foundation.

The defendant was pulled over for a broken headlight, and the officer observed that her speech was slurred and she smelled of alcohol. Moreover, she was wearing a wristband from a bar, and there was a plastic cup in the center console that seemingly contained alcohol. The officer administered an HGN test, which revealed four out of six cues suggesting impairment.
