The Arizona grand jury process is a secret charging procedure where jurors decide whether probable cause exists to indict a person under A.R.S. 21-407(A) and (B). Prosecutors may present evidence, but the accused usually does not appear unless the defense later challenges the indictment. In a DUI case, Arizona felony exposure can include 0.08% BAC, 0.15% extreme, or 0.20% super extreme, with mandatory jail, fines, and a license suspension through MVD. A second offense can mean at least 90 days in jail, 30 consecutive, and a $3,200 or higher fine.

How does the grand jury process work in Arizona?
In Arizona, the grand jury process starts when prosecutors present evidence to a panel of jurors in secret. The grand jurors decide whether there is probable cause to return a true bill, which means an indictment. Under A.R.S. 21-407, the proceedings are confidential, and that secrecy is meant to protect jurors, witnesses, and the investigation. The accused usually does not get to argue the case at this stage.
Because the process is one-sided, a target may not know about it until an indictment is filed. That is why early legal help matters. A defense lawyer can review what happened, preserve video, texts, records, and witness names, and prepare for what comes next in court.
What is a grand jury and what does it do in Arizona?
A grand jury is a group of citizens who listen to evidence and decide whether criminal charges should be brought. In Arizona, it acts as a screening body in felony cases, and the prosecutor must show probable cause, not proof beyond a reasonable doubt. The grand jury does not decide guilt or innocence, it only decides whether the state can proceed by indictment.
The process is especially important in serious cases, including drug crimes, assaults, weapons allegations, and other felony matters. If you are under investigation, an experienced Arizona criminal defense lawyer can explain the charge, help protect your rights, and respond before the case gets worse.
What happens if a grand jury indicts you?
If a grand jury indicts you, the case moves into the criminal court system as a formal felony prosecution. You will usually be arraigned, the court will set deadlines, and the defense can start challenging the evidence. An indictment is not a conviction, but it does mean the state convinced the grand jury that probable cause exists.
After indictment, your lawyer may attack search warrants, witness credibility, police reports, and any constitutional problems in the investigation. In DUI, drug, assault, domestic violence, and weapons cases, the early record matters a lot, because it can shape plea talks, motions, and trial strategy.
How does the grand jury process play out in local Arizona courts?
Grand jury cases are usually filed in the county court system where the alleged offense happened, then assigned to the local criminal court calendar.
