DUI Evidence

In a DUI case, like any other criminal case, before a jury (or a Judge) can consider the State’s evidence against, that evidence must be legally admissible. What that means is that the evidence against you can be suppressed (not heard) if your constitutional rights were violated by the police, or if the police did not follow the proper procedure and your case would likely be dismissed.

Reliability of the Evidence

If the evidence is not suppressed the State’s case against you will rest upon the reliability of the evidence. Generally the State’s evidence in DUI consists of the police officer’s testimony regarding his observations of your ability to drive (weaving, not using turn signal), your overall appearance, your behavior, the blood alcohol content test (BAC), your performance on the field sobriety tests, and any statements you made to the officer.

Inaccurate Evidence

None of the evidence against you is accurate 100% of the time. The officer’s testimony concerning your level of impairment is simply the officer’s subjective opinion and is open to argument as to why he is wrong. Additionally, the blood alcohol test is also not perfect. Many factors, including lack of maintenance, can invalidate test results. Many times what appears to be reliable evidence is wrong and can weaken the State’s DUI case. Each case is different and not everyone can successfully make these arguments. But you will never know if the machine was providing erroneous test results unless you have an experienced attorney request and examine the machine’s data. Without a full inquiry into the evidence against you, you may never know if there are issues with the prosecutor’s case against you.
