A California felony preliminary hearing is an early court proceeding where a judge determines whether the prosecution has presented enough evidence for the felony case to continue. It is sometimes informally called a “prelim” or probable-cause hearing.
This hearing is not a trial. The judge does not decide whether the defendant is guilty beyond a reasonable doubt. Instead, the prosecution must establish probable cause to believe that a felony occurred and that the defendant committed it.
Although the evidentiary threshold is lower than the standard required for conviction, a preliminary hearing can reveal important information about the prosecution’s case and influence how the case proceeds.
When Does a California Felony Preliminary Hearing Occur?
A preliminary hearing generally takes place after the defendant’s initial arraignment on a felony complaint.
At the arraignment, the defendant is informed of the charges, advised of important rights and asked to enter a plea. The court may also address legal representation, release conditions and scheduling.
The California Courts’ criminal case overview explains that felony cases generally include a preliminary hearing during the pretrial stage.
Our guide to what happens at an arraignment provides more information about the proceeding that normally comes before the preliminary hearing.
How Soon Must the Hearing Take Place?
Under California Penal Code Section 859b, both the prosecution and defendant have a right to a preliminary examination at the earliest possible time.
Unless the parties waive the deadline or the court finds good cause for a continuance, the hearing generally must occur within 10 court days after the arraignment or plea, whichever happens later.
The statute also contains a 60-day deadline. The complaint generally must be dismissed if the preliminary examination is set or continued more than 60 days after the arraignment or plea unless the defendant personally waives that right.
Exceptions and additional rules can apply. A dismissal based on a timing issue may not always prevent prosecutors from refiling charges.
Can the Defendant Waive the Preliminary Hearing?
Yes. A defendant may agree to waive the preliminary hearing, usually after discussing the decision with a defense lawyer.
A waiver allows the felony case to proceed without requiring the prosecution to present evidence at that stage. Defendants may consider a waiver as part of plea negotiations, to avoid revealing a defense strategy or for another case-specific reason.
However, giving up the hearing also means losing an opportunity to:
- Hear prosecution witnesses testify
- Cross-examine certain witnesses
- Evaluate the strength of the evidence
- Preserve testimony for later use
- Challenge whether probable cause supports the charges
- Learn details that may not appear in police reports
Waiving a preliminary hearing should be an informed strategic decision rather than an automatic procedural step.
What Must the Prosecutor Prove?
The prosecution does not need to prove guilt beyond a reasonable doubt at a California felony preliminary hearing. That higher standard applies at trial.
At the preliminary hearing, the prosecutor must present sufficient evidence to establish probable cause. In practical terms, the judge decides whether there is a reasonable basis to believe that:
- A crime was committed
- The charged defendant committed it
Probable cause is a relatively low evidentiary threshold. The judge generally does not resolve every factual conflict or decide which version of events is ultimately true.
A case may therefore survive the preliminary hearing even when the defense believes the prosecution’s evidence is weak or unreliable.
Who Attends the Preliminary Hearing?
People commonly present at the hearing include:
- The judge or magistrate
- The prosecutor
- The defendant
- The defense attorney
- A court reporter
- Court staff
- Law-enforcement witnesses
- Civilian witnesses when required
- An interpreter when necessary
The hearing is ordinarily conducted in open court, although legal rules may restrict access or testimony in particular circumstances.
A jury is not present. The judge alone determines whether the case should proceed.
What Happens During the Hearing?
The preliminary hearing resembles a shortened trial, but its purpose and procedures are different.
The Prosecution Presents Evidence
The prosecutor presents evidence supporting the felony charges. This may include testimony from:
- Police officers
- Investigators
- Alleged victims
- Eyewitnesses
- Expert witnesses
- Custodians or other people connected to records
Physical evidence, photographs, recordings, documents or laboratory information may also be introduced.
California law permits certain qualified law-enforcement officers to present hearsay testimony at preliminary hearings. As a result, the prosecution may not need to call every person who would be required to testify at trial.
The Defense Cross-Examines Witnesses
The defense attorney may question prosecution witnesses. Cross-examination can explore inconsistencies, gaps in the investigation, credibility problems and facts supporting the defense.
Potential subjects include:
- A witness’s ability to observe the event
- Conflicting descriptions
- Identification procedures
- Missing physical evidence
- Errors in police reports
- Bias or motive
- The timeline of events
- Whether the evidence supports every element of the charge
Cross-examination at a preliminary hearing can help the defense understand how an important witness may testify later.
The Defense May Present Evidence
The defense may present its own witnesses or evidence, but doing so is not always strategically helpful. Presenting a defense case early could disclose information the prosecution did not previously know.
The defense may instead focus on showing that the prosecution failed to establish probable cause.
The appropriate approach depends on the charges, available evidence and broader defense strategy.
Attorneys Make Legal Arguments
After evidence is presented, the attorneys may argue whether the prosecution satisfied the probable-cause standard.
The defense may ask the judge to dismiss one or more charges or enhancements. The prosecutor may argue that the evidence supports holding the defendant to answer in Superior Court.
What Does “Held to Answer” Mean?
If the judge finds probable cause, the defendant is “held to answer.” This means the felony prosecution may continue in Superior Court.
Being held to answer is not a conviction. It only means the prosecution presented enough evidence to move beyond the preliminary-hearing stage.
The prosecutor may then file a formal charging document called an information. The defendant is subsequently arraigned on that information and asked to enter a plea to the charges proceeding in Superior Court.
The case may then involve:
- Additional discovery
- Pretrial motions
- Plea negotiations
- Readiness conferences
- Trial preparation
- A jury trial
Can the Judge Dismiss the Charges?
The judge can dismiss a charge when the prosecution fails to establish sufficient cause to believe the defendant committed it.
Possible outcomes include:
- All charges proceed
- Some charges proceed while others are dismissed
- An enhancement is dismissed
- A felony is reduced when legally permitted
- The entire complaint is dismissed
A dismissal at the preliminary hearing does not necessarily end the matter permanently. Depending on the reason for dismissal and applicable law, prosecutors may be able to refile the charges or pursue review of the decision.
Our article about whether criminal charges can be dropped before trial explains other ways charges may be dismissed or discontinued.
Can the Charges Change After the Hearing?
Yes. The charges listed in the original complaint are not always the final charges in the case.
Following the preliminary hearing, the prosecution may file an information containing charges supported by the evidence presented. In some circumstances, the information may include related charges that were not stated exactly the same way in the original complaint.
The defense may challenge charges that exceed what the evidence or applicable procedural rules permit.
Are Victims Required to Testify?
An alleged victim may testify, but personal testimony is not required in every preliminary hearing. California’s evidentiary rules may allow a qualified officer to relate certain statements made by another person.
Whether the prosecutor calls the alleged victim can depend on:
- The nature of the charge
- The available witnesses
- The evidence needed to establish probable cause
- Hearsay rules applicable to preliminary examinations
- Witness availability
- Strategic considerations
If a witness is subpoenaed, that person should follow the subpoena and court instructions. Witnesses should not assume that attendance is optional.
Can Evidence Be Suppressed at a Preliminary Hearing?
Certain evidence issues may be raised before, during or after the preliminary hearing, depending on the legal basis and procedural requirements.
A defense attorney may examine whether police:
- Conducted an unlawful search
- Lacked probable cause for an arrest
- Obtained statements in violation of constitutional protections
- Used an improper identification procedure
- Failed to preserve important evidence
- Exceeded the scope of a warrant
A preliminary hearing is not automatically the final stage for litigating every evidentiary issue. California law provides specific procedures and deadlines for suppression motions and other challenges.
Can the Defendant Testify?
A defendant has the right to remain silent and generally cannot be forced to testify against themselves.
The defendant may choose to testify after receiving legal advice, but doing so can carry significant risks. The prosecutor may cross-examine the defendant, and the testimony may affect later proceedings.
Most defendants should not decide whether to testify without carefully discussing the consequences with their attorney.
Does the Preliminary Hearing Decide Bail?
The court may review bail or release conditions during the preliminary-hearing stage. The judge may consider the charges, evidence, criminal history, public-safety concerns, risk of nonappearance and compliance with existing release conditions.
Possible outcomes may include:
- Maintaining the current bail
- Increasing or reducing bail
- Modifying release conditions
- Releasing the defendant under authorized conditions
- Ordering continued detention where permitted by law
The specific rules depend on the charges and circumstances. A defendant should continue obeying every existing release condition unless the court formally changes it.
Is a Preliminary Hearing the Same as a Grand Jury?
No. Both procedures can play a role in establishing probable cause, but they operate differently.
At a preliminary hearing:
- A judge hears the evidence
- The defendant and defense attorney are present
- The defense may cross-examine witnesses
- A court record is created
In a grand-jury proceeding:
- Jurors evaluate evidence presented by the prosecution
- Proceedings generally occur in private
- The defense ordinarily does not participate in the same way
- The grand jury may return an indictment
Many California felony cases begin through a complaint and preliminary hearing, while some proceed through an indictment.
Is a Preliminary Hearing the Same as a Trial?
No. The differences are substantial.
| Issue | Preliminary hearing | Criminal trial |
|---|---|---|
| Main purpose | Determine probable cause | Determine guilt |
| Decision-maker | Judge | Judge or jury |
| Standard | Probable cause | Beyond a reasonable doubt |
| Scope | Limited review of evidence | Full presentation of the case |
| Result | Case proceeds or charges are dismissed | Acquittal or conviction |
| Final determination of guilt | No | Yes |
A defendant who loses at the preliminary-hearing stage remains presumed innocent.
How Long Does a Preliminary Hearing Take?
The length varies considerably. A relatively straightforward hearing may last part of a day. A case involving multiple defendants, numerous witnesses, technical evidence or several felony counts may require multiple court sessions.
The length can depend on:
- Number and complexity of charges
- Number of witnesses
- Volume of evidence
- Extent of cross-examination
- Legal arguments
- Interpreter needs
- Court scheduling
A hearing being brief does not necessarily mean the charges are unimportant. The prosecutor may be able to meet the probable-cause standard without presenting every piece of available evidence.
Why Is the Hearing Important for the Defense?
Even when dismissal is unlikely, a California felony preliminary hearing can provide valuable information.
The defense may use the proceeding to:
- Test witness accounts
- Identify contradictions
- Examine weaknesses in the investigation
- Clarify the prosecution’s theory
- Preserve testimony under oath
- Challenge unsupported charges
- Evaluate possible motions
- Prepare for negotiations or trial
Testimony from the hearing may become relevant if a witness later changes their account or becomes unavailable.
The information revealed can also affect plea discussions. Anyone evaluating a proposed agreement should understand the charges, evidence and consequences. Our guide on whether to accept a plea bargain discusses factors defendants may need to consider.
Preparing for a California Felony Preliminary Hearing
A defendant should work closely with counsel before the hearing. Preparation may include:
- Reviewing the criminal complaint
- Examining police reports and available discovery
- Identifying important witnesses
- Preserving messages, recordings and photographs
- Discussing possible defenses
- Evaluating whether to waive statutory deadlines
- Reviewing release conditions
- Preparing for possible outcomes
The defendant should arrive on time, dress appropriately and avoid discussing the case with witnesses or other people at the courthouse. Statements made outside the courtroom may still create legal problems.
