Few offenses in America's criminal justice process call for greater attorney expertise than cases involving driving under the influence of drugs and alcohol. DUI cases are especially complex because they require defense counsel to understand scientific, as well as legal processes. The legal issues are wide-ranging, involving search and seizure, due process, illegal interrogation, denial of counsel, and evidentiary issues. These legal issues intersect in a DUI case with scientific areas of expertise, such as anatomy, biology, chemistry, physiology, and toxicology, as well as pseudo-scientific areas such as field sobriety testing. DUI defense counsel must also have a working understanding of the operation of breath test equipment, hospital testing equipment, and instruments utilized by forensic laboratories in the process of testing for intoxicants.
