TLDR
- Arizona prosecutors bring a felony into superior court through one of two doors, a grand jury indictment or a preliminary hearing in front of a judge.
- A grand jury meets in secret, hears only what the prosecutor presents, and at least nine jurors must agree before an indictment issues.
- A preliminary hearing is public, your lawyer attends and cross examines the officer, and a judge decides whether probable cause exists.
- The door the prosecutor picks changes what you see, when you see it, and which motions your attorney files next.
Two doors into Arizona felony court
Every felony in Arizona needs a probable cause finding before it goes to trial in superior court. Probable cause is a low bar. It asks whether there is a reasonable basis to believe a crime happened and you committed it. Two bodies hold the power to make that finding, a grand jury or a judge at a preliminary hearing.
The prosecutor picks the door. You do not. The Maricopa County Superior Court criminal department handles the felony either way once probable cause is found, and the trial that follows looks the same. The road to get there does not.
With a direct complaint, the prosecutor files a written list of felony counts, a judge signs it, and you are summoned or arrested. Then comes the initial appearance, a status conference and a preliminary hearing date. With an indictment, the prosecutor skips the hearing and goes to the grand jury first. If the grand jury votes to indict, a judge issues a summons or a warrant, and your first court date is an arraignment. Our post on the difference between being detained, arrested and charged covers the steps before either door opens.
How a grand jury indictment works in Arizona
A county grand jury is a panel of twelve to sixteen citizens who serve for a term of months. In Maricopa County they sit several days a week and hear a long list of cases each day. The room is closed. The prosecutor presents, a court reporter records, and the jurors ask questions. No judge sits in the room. No defense lawyer argues. You are not told the date.
The prosecutor usually calls one witness, often the detective, who summarizes the police reports. Hearsay is allowed. At least nine jurors must agree before the grand jury returns an indictment, the formal charging document that names the counts. Jurors hold the power to add counts the prosecutor did not request, or to decline to charge at all. A refusal to indict is rare. The structure favors the prosecutor because only one side is talking.
Two protections exist, and both need a lawyer to work. First, a person under investigation has the right to ask the grand jury to hear from them or to consider evidence they point to. The jurors decide whether to grant it. Arizona law requires the jurors to weigh all the evidence they receive and lets them demand more when they have reason to believe something would explain away the charge. Second, the court reporter’s notes are transcribed and filed within twenty days after the indictment, and the transcript goes to you. That transcript is your first real look at what the grand jury was told.
The grand jury is also the usual path when charges come weeks or months after the incident. Our post on how long Arizona has to file charges explains the clocks that run during that silence.
How a preliminary hearing works in Arizona
A preliminary hearing is the open court version of the same question. A judge or commissioner presides. The prosecutor calls a witness, usually the arresting officer or the case agent, and your attorney cross examines that witness. Hearsay is allowed here too. At the end, the judge rules on probable cause. If the judge finds it, the case is bound over to superior court for arraignment. If the judge does not, the counts are dismissed, though the prosecutor remains free to refile or to go to a grand jury.
As of 2026, the preliminary hearing clock works this way. The hearing must be held within ten days of the initial appearance if you are in custody and within twenty days if you are out. The date goes on the calendar at the initial appearance along with a status conference. In Maricopa County, lower level felonies run through the Regional Court Center, and most first and second drug possession cases route through Early Disposition Court on an even faster track.
On the hearing date the prosecutor hands over a plea offer. Your lawyer weighs it against what the officer will say. Then you take the offer and waive the hearing, or you demand the hearing and make the prosecutor put a witness on the stand.
The hearing itself is short, often under an hour. Judges rarely dismiss at this stage. The value lies elsewhere. The officer testifies under oath, early, before stories harden, and your attorney gets a transcript and a first read on how the witness holds up under questions. When the prosecutor is not ready on the day, the hearing is scratched, and our post on what a scratched case means covers what follows.
Which door will the prosecutor pick?
The prosecutor chooses based on the kind of case and how it reached the office. The patterns are steady enough to predict.
Arrests at the scene usually bring a direct complaint and a preliminary hearing date. Aggravated DUI arrests, assaults with an arrest on scene, and drug possession cases follow this track.
Cases that come in later usually bring an indictment. Sex offenses, serious injury assaults, fraud and theft cases with records to gather, and anything with several victims or suspects almost always go to the grand jury. An indictment cancels both the status conference and the preliminary hearing. A direct complaint case that looks like it will be contested often gets vacated and sent to the grand jury instead. For someone in custody, that indictment usually follows within ten days.
The pick tells you something about the file. A rushed direct complaint means the case is thin and the office wants a plea at the first date. An indictment means the office spent time on the file and expects to try it. Both are winnable, in different ways.
The Law Behind This
| Charge or relief | What the law says | What it means for you |
|---|---|---|
| Class 6 undesignated felony | A.R.S. § 13-604 lets the prosecutor file a class 6 as a misdemeanor, and lets the complaint be amended to a misdemeanor, with your consent, before or during the preliminary hearing | The hearing date is a bargaining point on the lowest felony class, and an indictment takes that moment away |
| First felony sentencing range | A.R.S. § 13-702 sets prison ranges for a first felony, from half a year at the bottom of a class 6 to ten years at the top of a class 2 | The class on the complaint or the indictment sets your exposure, so the charging document is the first thing to attack |
| Aggravated assault | A.R.S. § 13-1204 ranks aggravated assault from class 2 to class 6 depending on injury, weapons, the victim and the setting | Injury and weapon cases tend to go to the grand jury, while a scuffle with an arrest on scene tends to get a hearing date |
| Dangerous drug possession | A.R.S. § 13-3407 makes personal use possession a class 4 felony, with a misdemeanor designation available on a first offense for most drugs | These cases run through Early Disposition Court on a fast hearing track |
| Aggravated DUI | A.R.S. § 28-1383 makes DUI a class 4 felony on a suspended license, a third offense in 84 months, an interlock order or wrong way driving, and a class 6 felony with a child under 15 aboard | Most aggravated DUI cases start with an arrest, a direct complaint and a hearing date |
What a felony defense attorney does at each door
The work starts before the door opens. If an investigation is running and no charge has been filed, a lawyer contacts the assigned prosecutor, offers the evidence the police skipped, and asks that the grand jury be told you want to be heard. Prosecutors are free to refuse. A letter from a lawyer still changes what the jurors hear and sometimes changes whether the case is presented at all. Our post on whether a lawyer stops charges before they are filed explains the prefile side of this.
On a direct complaint, the first job is the plea offer at the status conference. The second job is deciding whether to demand the hearing. We demand it when the officer’s story has holes, when the complaint overcharges what happened, or when a class 6 count should be filed as a misdemeanor before the case leaves the building. We waive it when the offer beats the risk, or when a hearing would hand the prosecutor a cleaner record for trial. Clients get a recorded video update after each date.
On an indictment, the first job is the transcript. We read every page the jurors heard and compare it to the police reports and the body camera footage. The second job is the arraignment, where release conditions get set and the trial judge gets assigned. From there the case runs on the same track as a bound over complaint, with disclosure, witness interviews and motions.
What happens when the grand jury got it wrong
An indictment is not the end of the probable cause fight. Arizona lets you ask the superior court judge for a new finding of probable cause. The motion argues that you were denied a substantial procedural right in the grand jury room. The strongest ground is a misleading presentation. The detective told the jurors something the reports do not support. The prosecutor left out evidence that clearly points away from guilt. A juror asked a question and got a wrong answer. If the judge agrees, the case goes back to the grand jury for a second presentation with the record corrected.
The deadline is tight. The motion must be filed within 45 days after the arraignment or after the transcript is filed, whichever comes later. Miss it and the ground is gone. An indicted client needs a lawyer reading the transcript in the first month, not the fourth.
A successful remand does not always mean a dismissal. Prosecutors often present again and get a second indictment. It does mean a cleaner record, fewer counts, and sometimes a lower class on the charge that survives. On a class 2 felony where the top of the first offense range is ten years, a count dropped at remand changes the entire case. Fees for a felony case are flat with payment plans, and the numbers are on our pricing page.

Frequently Asked Questions
Is a grand jury indictment worse than a preliminary hearing?
Neither is worse. They are different. An indictment means a panel of citizens already found probable cause on a one sided presentation, and your lawyer’s first chance to fight it is a remand motion after reading the transcript. A preliminary hearing gives you that fight in open court, and the sentencing exposure on the underlying charge is the same either way.
Do I get to attend the grand jury in Arizona?
Not as a matter of right. The grand jury meets in secret and you are not told the date. You have the right to ask to appear and to point the jurors toward evidence, and the jurors decide whether to hear it. If they do, your lawyer sits beside you but speaks only to you.
What does a grand jury target letter mean?
A target letter tells you the prosecutor plans to present your case to a grand jury and invites you to ask to testify. It is not a charge. It is a short window for a lawyer to send the prosecutor the evidence the police skipped and to decide whether appearing helps or hurts. Most people should not testify, and a lawyer makes that call case by case.
Should I waive my preliminary hearing?
Sometimes. Waiving makes sense when the plea offer beats any realistic trial outcome, or when the officer’s testimony would strengthen the prosecutor’s case for trial. Demanding it makes sense when the complaint overcharges what happened or the officer’s account has holes worth locking in under oath. The decision is made with a lawyer, on the day, with the offer in hand.
What happens if the prosecutor is not ready at the preliminary hearing?
The hearing gets scratched or vacated. A scratched hearing means the counts are dismissed for now, and the prosecutor is free to refile inside the time limit. A vacated hearing usually means the prosecutor is taking the case to a grand jury instead, and for someone in custody an indictment follows within days.
How many grand jurors have to agree to indict?
At least nine. A county grand jury has between twelve and sixteen members, nine make a quorum, and nine votes are required before the foreperson signs the indictment as a true bill. The jurors need only find probable cause, not guilt beyond a reasonable doubt.
Does an indictment mean I will be arrested?
Not always. After an indictment a judge issues either a summons or an arrest warrant. A summons is common when you have no record and the charge is not violent, and you appear at the arraignment on the date listed. A warrant is more likely on a serious charge or a history of missed court dates, and a lawyer sometimes arranges a self surrender so you are released the same day.
What is a motion to remand?
It is a request that the superior court judge send the case back to the grand jury for a new finding of probable cause. The usual ground is that the jurors were misled, or that evidence clearly pointing away from guilt was kept from them. The motion must be filed within 45 days after arraignment or after the transcript is filed, whichever comes later.
