A Motion To Suppress Is Vital In An Ohio DUI Case

In State v. French, 72 Ohio St. 3d 446, 1995-Ohio-32, 646 N.E. 2d 887 (1995), the Ohio Supreme Court held that a pretrial motion to suppress is the only way to challenge the admissibility of a chemical test.  If not filed, the results will be automatically admissible at trial.  The prosecuting attorney will not need to lay a foundation and any objection by the defense as to their admission will be overruled by the judge.  This makes choosing an experienced DUI attorney vital to your case as they will know what to challenge in a pretrial suppression motion.A motion to...

Community Control (Probation) in an OVI Case

If you are charged with a DUI (now called OVI; operating a vehicle impaired) chances are you will be placed on probation at the disposition of your case. Probation is now called "community control" and provides for terms and conditions you must comply with in order not to go to jail.  Probation requires you to work with a "probation officer" (P.O.) for a given period of time as set by the court.  A common misconception is that the probation officer will actively work against you in an effort to return you to jail.  Most of the time, the probation officer is working to make...

Gas Chromatography Mass Spectrometry (An Overview)

To fully comprehend the processes of chemical testing, your DUI attorney should understand gas chromatography - mass spectrometry. Gas chromatography mass spectrometry (hereinafter GCMS)  is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample.  GC-MS has been widely heralded as a "gold standard" for forensic substance identification because it is used to perform a specific test.Ohio Administrative Code 3701-53-03(A) sets forth the techniques and methods for determining the concentration of alcohol in blood, urine and other bodily substances.  Pursuant to that rule, Ohio allows for testing including gas chromatography and enzyme assays.  The GCMS instrument is...

DUI Science and Blood Contamination

The practice of modern DUI law involves understanding the various scientific tests that have become commonplace in forensic collection and storage of specimens for alcohol analysis.  Specifically, DUI attorneys must understand that contamination can increase the concentration of ethanol in a specimen.  Typically, contamination takes one of two forms.  The first is straight-forward physical contamination which may manifest itself before, during or after collection.  The second form of contamination occurs when microorganisms contaminate a sample and produce ethanol in the sample thereby falsely inflating the amount of ethanol therein.  This article will focus on the physical contamination that may cause...

DaytonDUI, Defending a Breath Test Case

"I'll Huff and I'll Puff and Blow Your House Down" Did you know that your breathing pattern can significantly alter the concentration of alcohol on your evidential breath test?  According to scientific research, "[t]he subject's test manner of breathing just prior to providing breath for analysis can significantly alter the concentration of alcohol in the resulting exhalation." (Jones, 1982, Schoknecht, 1989) as cited in Physiological Aspecs of Breath-Alcohol Measurement, Alcohol Drugs & Driving Vol. 6, No. 2, A.W. Jones.Hyperventilation "...
