Preliminary Hearing

A preliminary hearing is the pretrial filter for California felony cases. A judge — not a jury — listens to the prosecution’s evidence and decides whether there is enough to make the defendant stand trial. The legal standard is much lower than at trial, but the hearing itself is one of the most important strategic opportunities the defense has in the entire case.

How Preliminary Hearings Work in California

California preliminary hearings are governed by Penal Code §§ 858 through 883. Under § 859b, a felony defendant in custody is generally entitled to a preliminary hearing within 10 court days of arraignment, with limited exceptions. The hearing is held in front of a magistrate, who is typically a Superior Court judge sitting in a magistrate role. The prosecution presents its evidence, the defense can cross-examine witnesses and present its own evidence, and at the end the magistrate decides whether to “hold the defendant to answer.”

The legal standard at a preliminary hearing is probable cause — the same standard used for arrest. Under Penal Code § 872, the magistrate must find sufficient cause to believe both that a public offense has been committed and that the defendant is connected with it. This is dramatically lower than the beyond a reasonable doubt standard required at trial. Hearsay evidence is also broadly admissible at preliminary hearings under Proposition 115 and Penal Code § 872(b), allowing qualified law enforcement officers to testify about statements made by witnesses they did not personally interview.

If the magistrate finds probable cause, the defendant is “held to answer,” and the prosecution files an information in Superior Court within 15 days under Penal Code § 739. From that point forward, the case follows the standard California felony trial track. If the magistrate does not find probable cause as to a charge, that charge is dismissed — though under § 739, the prosecution can sometimes recharge offenses shown by the evidence even if the magistrate did not specifically hold on them. After a preliminary hearing dismissal, the prosecution generally has limited ability to refile under Penal Code § 1387.

The preliminary hearing also produces a transcript that becomes a permanent part of the case. Witness testimony given under oath at the hearing can be used as impeachment material at trial if the witness’s account changes. In some cases, where a witness later becomes unavailable, the preliminary hearing testimony can even be admitted at trial under Evidence Code § 1291 — making the cross-examination at the prelim its own form of trial preservation.

Why Preliminary Hearings Matter to Your Defense

The preliminary hearing is one of the most underused defense opportunities in California felony practice. It is the only stage before trial where the defense can cross-examine the prosecution’s key witnesses under oath. A well-prepared preliminary hearing can produce dismissals, reduce charges, weaken witnesses for trial, and lock in testimony that becomes powerful impeachment material later. Far too many felony cases are lost simply because the defense treats the prelim as a formality.

Skilled cross-examination at the preliminary hearing requires deep preparation. Defense attorneys who study every police report, every body camera video, and every prior witness statement before the hearing — and who develop a clear theory of what to lock in and what to expose — produce results that ad-hoc questioning never matches. Even when the case is held to answer, the work done at the prelim shapes everything that follows.

The hearing also drives Penal Code § 995 motion practice. After the prelim, the defense can move to set aside the information when the magistrate’s holding is not supported by sufficient evidence or when the proceedings were defective. Successful § 995 motions can dismiss counts, strike enhancements, and reshape the case entirely. This is the kind of careful, document-heavy California criminal defense work that separates routine representation from real advocacy in serious felony matters.

The preliminary hearing connects to the broader framework of charging through an information rather than a grand jury indictment, the standards of probable cause, and the cross-examination dynamics that drive a strong defense at every stage.
