A preliminary hearing is a court proceeding in a California felony case where a judge decides whether the prosecution has enough evidence to send the case to trial. Often called a “prelim,” it works like a mini trial: witnesses testify under oath, attorneys cross-examine them, and a judge rules at the end. But no jury is present, and the prosecutor does not have to prove guilt beyond a reasonable doubt. The only question is whether probable cause exists to believe a crime was committed and that the defendant committed it.
For anyone charged with a felony, the preliminary hearing is one of the most important dates in the entire case. It is the first real test of the prosecution’s evidence, the first chance to see and question the state’s witnesses, and often the moment when cases get dismissed, reduced, or resolved. Here is how the process works in California, what to expect in the courtroom, and the strategic decisions you and your attorney will face.
What Is a Preliminary Hearing?
A preliminary hearing is a probable cause hearing required in felony cases after the prosecutor files a criminal complaint. Under Penal Code 872, the judge, sitting as a magistrate, must answer two questions: is there sufficient cause to believe a crime was committed, and is there sufficient cause to believe the defendant is the person who committed it? If the answer to both is yes, the defendant is “held to answer” and the case moves toward trial. If not, the charges are dismissed.
The preliminary hearing functions as a screening mechanism. Its purpose is to weed out weak felony cases before they consume the time and expense of a jury trial, and to ensure that no one is forced to stand trial on charges the evidence cannot support.
Probable Cause: The Burden of Proof at a Prelim
The standard at a preliminary hearing is far lower than at trial. The prosecution only needs to present facts that would lead a reasonable person to a strong suspicion of the defendant’s guilt. That is a much easier bar to clear than proof beyond a reasonable doubt, which is why prosecutors win most preliminary hearings. But “most” is not “all,” and even when the case survives, the defense often walks out with something valuable: locked-in testimony, exposed weaknesses, and a clearer picture of what a trial would look like.
Do Misdemeanor Cases Have Preliminary Hearings?
No. Preliminary hearings apply only to felony prosecutions. Misdemeanor cases move from arraignment through pretrial conferences directly to trial or a negotiated resolution. One exception worth knowing: if a felony complaint also includes misdemeanor counts, those counts ride along through the preliminary hearing with the felony. In the rare California case that begins with a grand jury indictment instead of a complaint, there is no preliminary hearing at all.
When Does the Preliminary Hearing Happen? The 10-Day and 60-Day Rules
Timing is governed by Penal Code 859b, and the deadlines have real teeth. A defendant has the right to a preliminary hearing within 10 court days of arraignment or their not guilty plea. If the defendant is in custody and the hearing does not happen within those 10 court days, the complaint generally must be dismissed. Separately, the hearing must be completed within 60 calendar days of arraignment unless the defendant personally waives time.
In practice, many defendants waive these deadlines. Waiving time gives the defense room to obtain discovery, investigate, file motions, and negotiate. Whether to insist on a speedy prelim or waive time is a strategic call: a fast hearing pressures an unprepared prosecutor, while a waiver buys preparation time for a complex defense. Your attorney should make that decision deliberately, not by default.
What Happens at a Preliminary Hearing? Step by Step
A preliminary hearing follows a predictable structure:
- The prosecution presents its case. The DA calls witnesses, usually starting with the investigating officer, and introduces reports, photos, and other evidence.
- The defense cross-examines. Your attorney questions each witness under oath, testing their credibility and pinning down their story. Everything said becomes a transcript the defense can use at trial, and inconsistencies discovered here often become impeachment material later. This is also where gaps in the discovery the prosecution has turned over tend to surface.
- The defense may present evidence. The defense has the right to call witnesses and introduce evidence, though it often chooses not to reveal its hand this early.
- Both sides argue. The defense argues the evidence fails to establish probable cause on some or all counts; the prosecution argues the opposite.
- The judge rules. The magistrate holds the defendant to answer on some or all charges, dismisses charges, or reduces eligible felonies to misdemeanors.
Most preliminary hearings last one to two hours, though complex cases involving multiple counts or witnesses can run a full day or longer.
Can Police Officers Testify to Hearsay at a Prelim?
Yes, within limits. Under Proposition 115, codified at Penal Code section 872(b), a qualified law enforcement officer may testify at the preliminary hearing to what victims and witnesses told them, which means the prosecution often does not call civilian witnesses at all. The officer is limited to one level of hearsay, and this shortcut applies only at the prelim. At trial, the actual witnesses must appear and testify. For the defense, that difference is useful: if the prosecution’s prelim case is built entirely on an officer reciting statements, the real test of those witnesses is still to come.
Does the Defendant Testify?
Almost never. The defendant has the right to remain silent at the preliminary hearing, and testifying rarely helps at this stage because the probable cause bar is so low. Anything the defendant says becomes sworn testimony the prosecution can use later. In nearly every case, the defense strategy is to listen, cross-examine, and preserve every advantage for trial or negotiation.
Possible Outcomes of a Preliminary Hearing
The judge has more options than a simple yes or no:
- Held to answer. The judge finds probable cause on some or all counts, and the case proceeds toward trial.
- Dismissal. If the evidence fails to establish probable cause, the judge dismisses the charge or the entire case. The prosecution can sometimes refile, but a dismissal at prelim is a major defense victory and often the end of the matter.
- Charges reduced or trimmed. The judge can hold the defendant to answer on fewer counts than charged, or find probable cause only for lesser offenses.
- Felony reduced to a misdemeanor. For wobbler offenses that can be charged either way, the judge has the power under Penal Code 17(b)(5) to reduce the felony to a misdemeanor at the preliminary hearing. For many defendants, this reduction is the single most valuable outcome a prelim can produce.
Even a “loss” at the prelim can set up a win later. The transcript becomes a fixed record of what the witnesses said, and any charge the evidence barely supports becomes a target for the next motion.
Should You Ever Waive Your Preliminary Hearing?
Sometimes. Prosecutors occasionally offer a better plea deal in exchange for waiving the prelim, because the hearing costs them time and forces their witnesses on the record. If the evidence is overwhelming and the offer is genuinely favorable, waiving can make sense as part of a negotiated resolution, and your attorney will walk you through what pleading guilty or no contest would actually mean before you give anything up.
A preliminary hearing should never be waived casually. It is the defense’s one guaranteed chance before trial to test the state’s witnesses under oath, and everything learned there feeds into motions, negotiations, and trial strategy. As a rule, the weaker the prosecution’s case, the more valuable the hearing.
What Happens After a Preliminary Hearing?
If the defendant is held to answer, the prosecutor has 15 days to file a document called an information, and the defendant is arraigned again in superior court, this time on that charging document. The case then moves into the trial track: pretrial conferences, motions, and ultimately a jury trial or a negotiated resolution.
The prelim also unlocks a powerful post-hearing tool. If the defense believes the defendant was held to answer without sufficient evidence or that the hearing was legally defective, it can file a 995 motion to dismiss, asking the superior court to set aside the information. Charges that squeaked through the prelim on thin evidence are exactly what 995 motions exist to eliminate.
Frequently Asked Questions About Preliminary Hearings
How long does a preliminary hearing take?
Most take one to two hours. Cases with multiple charges, several witnesses, or contested suppression issues can last a full day or stretch across several sessions. The hearing is short compared to a trial because the prosecution only needs to establish probable cause, not prove guilt.
Can charges be dropped at a preliminary hearing?
Yes. If the judge finds the evidence insufficient on any count, that count is dismissed, and if no count survives, the entire case is dismissed. Judges also routinely trim overcharged cases at the prelim by dismissing enhancements or holding the defendant to answer on lesser charges.
Is a preliminary hearing the same as a trial?
No. A judge decides instead of a jury, the burden of proof is probable cause instead of beyond a reasonable doubt, limited hearsay is allowed, and no one is found guilty or not guilty. The prelim decides only whether the case may proceed to trial.
What is a holding order?
A holding order is the judge’s ruling at the end of the preliminary hearing that the defendant must “answer” the charges in superior court. It means the judge found probable cause. It is not a finding of guilt, and every trial right, including the presumption of innocence, remains fully intact.
Can the judge reduce a felony to a misdemeanor at the prelim?
Yes, for wobblers. If the offense is one that California law allows to be charged as either a felony or a misdemeanor, the judge can reduce it to a misdemeanor at the preliminary hearing. The defense can request this reduction based on the weakness of the evidence, the defendant’s record, and the circumstances of the offense.
