What Is a Preliminary Hearing? A Plain-English Guide for California Felony Cases
If you've been charged with a felony in California, somewhere between your arraignment and any trial there's a court date called the preliminary hearing. Most people have never heard the term before it lands on their paperwork, and the name doesn't help — it sounds like a formality. It isn't. For a great many felony cases, the preliminary hearing is the most important day in court that ever happens, because most cases never reach trial at all.
This post explains what a preliminary hearing is, how it differs from a trial, and what actually happens in the courtroom, step by step.
This is general information, not legal advice. Every case is different, and the only way to understand what a preliminary hearing means for your case is to talk with an attorney.
The short version
A preliminary hearing is a probable cause hearing in a felony case. The judge decides whether there's enough evidence to send the case forward — not whether you're guilty.
The standard is low, and the judge is required to view the evidence in the light most favorable to the prosecution.
Misdemeanors don't get one. Preliminary hearings exist only in felony cases.
It happens early: generally within 10 court days of your arraignment or not-guilty plea, unless you waive that timeline.
It is not a trial. No jury, no "beyond a reasonable doubt," no verdict.
What a preliminary hearing is actually for
After you're arraigned on a felony, the prosecution has accused you of something — but nobody neutral has yet looked at their evidence and asked whether it holds up well enough to justify putting you through a felony trial.
That's the job of the preliminary hearing. The prosecutor puts on evidence, your attorney tests it, and the judge answers one question:
Is there probable cause to believe a felony was committed and that this defendant committed it?
If the answer is yes, the judge “holds you to answer” or “binds you over” (different ways of saying the same thing) and the case moves to the next stage. If the answer is no, the judge dismisses the charge.
The purpose, at its core, is protective. It's a filter that exists so people aren't forced to defend unsupported felony charges all the way through a trial.
How a preliminary hearing is different from a trial
This is the distinction that trips up almost everyone, so it's worth taking slowly. A preliminary hearing looks like a trial — courtroom, judge, witnesses, sworn testimony, cross-examination — and it is nothing like a trial in the ways that matter.
The question is different. A trial asks whether you're guilty. A preliminary hearing asks only whether there's enough evidence to proceed. A judge can be personally unconvinced of your guilt and still, correctly, send the case forward.
The burden of proof is far lower. At trial, the prosecution must prove guilt beyond a reasonable doubt — the highest standard in American law. At a preliminary hearing, it needs only probable cause: enough to lead a person of ordinary caution to entertain a strong suspicion. Prosecutors clear that bar in the large majority of preliminary hearings, and that's not a sign anything went wrong. It's a sign of where the bar sits.
There's no jury. A trial is usually decided by twelve jurors. A preliminary hearing is decided by one judge alone.
The evidence rules are looser. At trial, the rules of evidence apply in full, and you have the right to confront the witnesses against you. At a preliminary hearing, California allows something it doesn't allow at trial: under Proposition 115, a properly qualified law enforcement officer can testify about what other people said (i.e. hearsay) and the judge can find probable cause based on that testimony. In practice, this means the prosecution often calls a single investigating officer instead of the alleged victim and every witness. The officer must meet specific experience or training requirements, and your attorney can cross-examine them and challenge whether they qualify at all.
The prosecution shows less of its hand. They only need to put on enough to clear the probable cause bar, so they typically put on the minimum, and no more.
The outcome is different. A trial ends in a verdict: guilty, not guilty, or a hung jury. A preliminary hearing ends in a holding order or a dismissal, and a dismissal at this stage is often not permanent: the prosecution can, in many circumstances, refile the case.
Your defense is narrower. Your attorney's right to call defense witnesses at a preliminary hearing is limited in ways it isn't at trial. This is a day for testing the prosecution's case, not presenting your own.
Here's the way to hold all of that in your head at once: a trial is where the case is decided. A preliminary hearing is where the case is tested.
Why it matters
If the prosecution almost always wins, and it's not a trial, why does anyone treat it as the most important day in the case?
Because winning isn't the only thing that happens there.
It's the first time anyone testifies under oath. Police reports are summaries written by one side. The preliminary hearing is where a witness has to say it out loud, under oath, and answer questions about it. Testimony that shifts, contradicts the report, or falls apart under cross-examination is captured permanently in the transcript — and that transcript can be used to impeach the witness at trial if they change their story again.
It's where cases get valued. Most felony cases resolve by negotiation, not trial. The preliminary hearing is where both sides learn what the case is really worth. A case that looked strong on paper and wobbled in the courtroom is a case that gets a better offer afterward. That's not a technicality; it's how most outcomes are actually shaped.
Some charges fall away. A judge might find probable cause on some counts and not others, or hold you to answer on a lesser offense than the one charged. You don't have to win outright to gain ground.
Motions can be heard at the same time. In many cases, a motion to suppress evidence — arguing that a search or stop was unlawful — can be brought at the preliminary hearing. If key evidence is suppressed, what's left may not support probable cause at all.
Even a loss produces something valuable. You walk out with a transcript, a preview of the prosecution's theory, and a much clearer picture of the road ahead.
The steps, in order
1. Arraignment. At your felony arraignment, you're advised of the charges, you enter a plea, and the court sets the preliminary hearing date. In Sonoma County, that's now at the Hall of Justice at 625 Administration Drive in Santa Rosa. (See our post on the new courthouse and courtroom assignments if your paperwork still lists the old building.)
2. The 10 days, or a waiver. California law gives both sides the right to a preliminary hearing at the earliest possible time — generally within 10 court days of your arraignment or plea, whichever comes later, and in any event within 60 calendar days of arraignment unless you personally waive that right. Miss those deadlines without a valid waiver or good cause, and the charge must be dismissed.
In some cases, defendants waive time on the advice of counsel, especially when they're out of custody. Ten court days is barely two weeks to obtain discovery, review body-worn camera footage, locate witnesses, and prepare cross-examination; a rushed hearing usually helps the prosecution more than it helps you. If you're in custody, the calculus changes, because the timeline is also what limits how long you sit in jail before the case is tested. This decision is one of the more consequential ones early in a case, and it's exactly the sort of thing to talk through with your attorney rather than decide at the counsel table.
3. Preparation. Your attorney gets discovery from the prosecution — reports, video, recordings, lab results — and builds the cross-examination. This is where the hearing is actually won or lost.
4. The hearing itself. You appear, and the case is called. The prosecution presents its evidence: witnesses testify under oath, and physical evidence, video, and records may come in. Often this is one investigating officer, testifying in part to what others told them. Your attorney cross-examines each witness, pinning down details, exposing gaps, and locking testimony into the record.
5. The defense side. Your attorney may cross-examine, argue the evidence, litigate a suppression motion, or in limited circumstances call a witness. You have the right to remain silent, and defendants very rarely testify at a preliminary hearing.
6. Argument and ruling. Both sides argue whether the probable cause standard is met. The judge rules from the bench — usually the same day. Most preliminary hearings run from about half an hour to a few hours; complicated ones can go longer or span multiple days.
7. What comes next.
Held to answer: The prosecution files an information — the formal charging document that replaces the complaint — and you're arraigned again on it in the trial court. Pretrial motions, negotiations, and possibly trial follow.
Dismissed: The charge or the case is dismissed. Depending on the circumstances, the prosecution may be able to refile, so a dismissal isn't always the end.
Reduced: You may be held to answer on fewer counts or lesser charges than the prosecution originally filed.
What you should do on the day
Show up early, dress as you would for a job interview, and bring your paperwork. Confirm your courtroom before you go. You can check the court's daily calendar, particularly right now while Sonoma County is moving into the new building. Silence your phone. Don't discuss your case with anyone but your attorney, and that includes hallways, elevators, and jail phone calls, all of which are less private than they feel.
And expect the case to move forward. That's the ordinary outcome of a preliminary hearing, and it does not mean the day went badly.
Frequently asked questions
Is a preliminary hearing a trial? No. There's no jury, no verdict, and no finding of guilt. The judge decides only whether there's enough evidence for the case to continue.
Do I have to go? Yes. A felony defendant is generally required to be personally present at the preliminary hearing, and failing to appear can result in a bench warrant.
Can I be found guilty at a preliminary hearing? No. Guilt isn't on the table. The only rulings available are holding you to answer or dismissing.
Do misdemeanors have preliminary hearings? Cases that charge only misdemeanors do not have preliminary hearings.
Should I waive time? Sometimes yes, sometimes no. It depends heavily on whether you're in custody and how much preparation your case needs. It's a strategic decision to make with an attorney.
Can I skip the preliminary hearing? You can waive it with consent. Doing so gives up your best early chance to test the prosecution's evidence, get witnesses on the record under oath, and possibly narrow the charges so it's not a step to give away lightly, and there are limited situations where it makes sense as part of a negotiated resolution.
Will my accuser have to testify? Not necessarily. Because of Proposition 115, the prosecution can often present the case through a qualified officer relating what witnesses said, rather than calling those witnesses live.
How long does it take? Most last from about thirty minutes to a few hours, depending on how many witnesses testify and how complex the case is. Complex preliminary hearings can go on for days.
What if the judge dismisses my case? That's a good outcome, but confirm with your attorney whether the prosecution can refile before you consider the matter closed.
