The Court Process Timeline
The DUI court process in Maricopa County generally follows these steps:

The arraignment, also known as the first appearance, is your initial court hearing. In Maricopa County, this often takes place within 24 hours of your arrest. According to research, the initial appearance often occurs inside the Intake, Transfer, and Release (ITR) facility. At the arraignment, you will be formally advised of the charges against you, and the judge will inform you of your rights. You will also be asked to enter a plea of guilty, not guilty, or no contest.
-
Entering a Plea: If you plead "not guilty," your case will proceed to the next stage. A "no contest" plea is treated similarly to a guilty plea.
-
Court-Appointed Attorney: If you cannot afford an attorney, you can request a court-appointed attorney at the arraignment.
2. Pre-Trial Hearings
Following the arraignment, a series of pre-trial hearings will be scheduled. These hearings are used to:
-
Discovery Process: The prosecution will provide you with the evidence they have against you, including police reports, breathalyzer or blood test results, and witness statements. This is known as the "discovery" process.

3. Trial (If No Plea Deal)
If you and the prosecutor cannot reach a plea agreement, your case will proceed to trial.
-
Jury vs. Bench Trial: You have the right to a jury trial, where a panel of your peers will decide your guilt or innocence. You can also choose a bench trial, where the judge alone makes the decision.
-
What the Prosecution Must Prove: The prosecution must prove beyond a reasonable doubt that you were driving under the influence of alcohol or drugs, as defined by Arizona Revised Statutes (A.R.S.) Title 28.
-
Common Defenses: Common defenses in DUI cases include challenging the accuracy of the breathalyzer or blood test, arguing that you were not impaired, or claiming that the police violated your rights.
