Q: Which types of evidence can be challenged in a DUI case?
In a DUI case, several types of evidence can be challenged under California DUI law. One common basis for challenging evidence relates to the procedures used during the traffic stop and subsequent arrest. If law enforcement did not have probable cause to initiate the stop, any evidence gathered following that stop may be deemed inadmissible. This includes field sobriety tests, breath tests, or blood tests performed without justifiable cause.
Additionally, the reliability and accuracy of breath and blood tests can be questioned. This may involve examining whether the testing devices were properly calibrated and maintained, as well as scrutinizing the qualifications of the personnel administering the tests. If there is a failure to follow established procedures or if the integrity of the samples can be brought into question, this evidence may be challenged in court.
Moreover, witness testimony can also be challenged. This includes evaluating the credibility and reliability of both law enforcement officers and any other witnesses involved. A defense attorney may cross-examine these witnesses to expose potential biases, inconsistencies in their accounts, or uncertainties regarding what they observed. Each of these angles provides a potential strategy for a defense in contesting the evidence presented in a DUI case.
