What DUI evidence will the state of California use to prosecute a DUI defendant for DUI?

In order to sustain a criminal conviction for DUI in California, the state, represented by the District Attorney's office, must produce evidence sufficient to satisfy the burden of proof for a criminal DUI conviction of the DUI defendant in criminal court. In a DUI case, like any other criminal case, the evidence is governed by the rules of evidence and the burden of proof is entirely on the state to prove that the DUI defendant is guilty of driving under the influence (a criminal violation). In order to satisfy the burden of proof, evidence is presented through witness testimony and physical evidence such as reports admitted into evidence, like forensic toxicology reports, police reports, forensic toxicology testimony, police testimony, and other witness testimony. Some evidence may be admissible to the DUI criminal court. However, some evidence may be inadmissible in the DUI criminal court proceedings, which means that the state can not use the evidence in the DUI court proceedings, if the evidence is deemed inadmisible. In order to properly anaylze the DUI evidence in a DUI case, knowledge of criminal law and forensic toxicology is essential. Once all discovery is concluded, and if the DUI case is still unresolved, the state must prove its DUI case to the court, beyond all reasonable doubt. The evidence in the DUI case is presented at a trial. Evidence of violation of DUI is necessary to prove beyond all reasonable doubt, a criminal violation of the DUI laws was committed by the DUI defendant. What evidence will the state use in the DUI prosecution? Is all witness testimony admissible? Can witness testimony be refuted? Does the police report come into evidence in the DUI case? Does the toxicology report come into evidence in the DUI case?

The state will begin its DUI case with an opening argument as to how the defendant violated the drunk driving laws in California and why the DUI defendant should be criminally convicted of driving under the influence. After the opening argument in the criminal DUI case, the District Attorney will present witnesses to the court, and will attempt to admit evidence in the DUI proceeding, like witness testimony, forensic toxicology reports, showing blood alcohol content, and police reports in order to prove that the DUI suspected was in violation of the California state DUI laws. The DUI witnesses will most likely testify as to facts that that the witness personally observed and to their opinions (if admissible) on the DUI matter. For example, the police officer who arrested the DUI defendant may testify as to what the police officer witnessed regarding field sobriety test administration and the results of the police observations. If the witness is qualified to testify as an expert, the witness may testify as an expert, as to how or why the drunk driving defendant violated the DUI law. Sometimes lay opinions are also admitted into the DUI judicial proceedings. Expert testimony and the evidence introduced as a result of the expert analysis is frequently determinative of the guilt in court of the DUI defendant. After all the evidence is presented to the court in the DUI trial, the prosecution concludes with a closing argument in the DUI case. It is at this point that the Judge or jury review the evidence and render a verdict to the court, as to whether the DUI defendant is guilty of driving under the influence as proscribed by the law.
