A California driving under the influence (DUI) case is just like any other criminal case in which the District Attorney must prove that the offender is guilty beyond a “reasonable doubt.” Every criminal case, whether it is a California DUI case or a driving under influence of drugs case, hinges on the District Attorney’s ability to establish “beyond a reasonable doubt” that the offender is guilty. If he or she is unable to do so, then the offender is entitled to a ruling of “not guilty.”
The District Attorney will need to prove that the offender was in fact “driving a vehicle,” was under the influence of alcohol or drugs, and/or in violation of California’s Per Se laws . If he or she can not prove these things, then the case is lost for the state. An experienced California DUI attorney will be able to challenge these issues and most often can obtain either a lesser DUI charge or a not-guilty ruling.
