I received an email via my contact page from John Adam, who wanted to wanted to give some perspective on how to challenge the Breathalyzer test. Interesting stuff - Tom
The use of breath to determine the blood alcohol level of a person is the most popular scientific method in DUI cases. There are many cases, when the wrong Breathalyzer tests cause the person, under suspicion of driving while drinking, face DUI charges. Breathalyzer results are inaccurate because of certain problems with calibrations or if there is an untrained police officer using the device.
The prosecuting party has to prove in the court that the defendant's BAC was at or above the legal limit. In a few states, it is .10% while in others it is .08%. When the person is wrongfully charged on the basis of defective Breathalyzer tests, the defendant needs a DUI attorney
to challenge the Breathalyzer test in court.
The Burden of Proof in Challenging the Results:
Under the wrongful DUI charges, the defendant must prove that these charges are invalid for the conviction. This is possible when the attorney convinces the court that there is a lack of strength in evidence or it is insufficient to convict the accused. The defense team may focus on the witness statement and evidence without having the burden of proof. When the defense refutes the proof and demonstrates that the prosecution has not strengthened in the case, this may help in dismissing the
Use of Breathalyzer:
There are many cases when the Breathalyzer is not used properly. The police officer uses the device inaccurately given improper maintenance, training or calibration, which gives the inaccurate results. When the prosecuting party has Breathalyzer results as the only evidence, by only refuting this proof it becomes easy as well as effective to defend the person from the conviction. However, in this case, the defense team needs the help of an expert in these devices or understands well the proper calibration to give accurate results.
Training of the Police Officer:
In many cases, the police officer who pulls over the driver on suspicion of being under the influence of drug or alcohol, may not be properly trained to conduct a Breathalyzer test or use the device. The device cannot provide the results if the officer does not use it accurately. There are certain rules for this such as observing the driver for twenty minutes to determine whether the results are accurate or not. Moreover, the office is supposed to check the intestinal health of the accused or alcohol in the mouth.
Breathalyzers have settings as well as calibrations that need regular maintenance and understanding. In case the officer in charge is unaware of how to set the device and keeps it maintained, the device can produce the wrong results.
Few devices need to be repaired and parts replaced. In case of lack of knowledge about taking care of the device, there will be inaccurate results leading to wrong DUI charges. Not only one, but all or most of the arrest will be affected.
Challenging the Results Varies According to the Case:
In addition to the above-mentioned ways, there are other ways to challenge the Breathalyzer tests. For instance, the accused may have a special condition that could lead to the retention of the alcohol in his or her system that brings wrong results. This is another effective to challenge the results and refute the charges completely.
Other factors involved, the environmental temperature and pressure in the atmosphere, and the chemical composition of the person taking the test. This refers to the emotional stress and physical activity, hyperventilating, heavy breathing due to anxiousness.
Given these several factors, the results are inaccurately measured. This is the reason few of the DUI cases involve expert witness who gives the testimony about the inaccuracy of the device with incorrect results. The DUI attorney must present the valid argument based upon these facts and evidence.
The defendant needs the support of the lawyer to challenge the Breathalyzer tests, as the attorney is skilled in dealing with such cases and will guide according to the given circumstances.
