Facing a felony accusation can make it feel like your future has already been decided. But in many California cases, there is an important early checkpoint before trial: the probable cause hearing, more commonly called a preliminary hearing.
A preliminary hearing is not a trial. There is no jury, and the prosecution does not have to prove guilt beyond a reasonable doubt. Instead, a judge closely evaluates whether the government has enough evidence to keep the felony case moving forward.
For someone accused of an Orange County crime, this hearing can be a critical opportunity. The prosecutor must present evidence connecting the accused to a public offense. But a criminal defense attorney can challenge the reliability of that evidence, test the credibility of key witnesses, and expose weaknesses that may otherwise go unnoticed until much later.
Under California Penal Code section 872, a judge can only move a case forward to trial when the evidence shows that a public offense was committed and there is sufficient cause to believe the defendant committed it. If the prosecution cannot make that showing, the case may not proceed in its current form.
What Prosecutors Must Show
The prosecution carries a minimal burden at a preliminary hearing compared with trial. This means prosecutors must establish probable cause, not whether guilt has been proven beyond a reasonable doubt. Put simply, prosecutors need enough evidence to create a reasonable basis for believing a crime occurred and that the defendant may be responsible.
But that lower standard does not mean the prosecutor gets a free pass. The court must still evaluate whether the evidence supports each charge. And in many cases, the prosecution relies heavily on police reports, physical evidence, and witness testimony.
California law allows a magistrate to consider certain hearsay testimony from qualified law enforcement officers. That can make preliminary hearings procedurally different from a jury trial. However, the defense can still challenge whether the testimony is reliable, whether the investigation was thorough, and whether the available facts actually support the charged offense.
If the judge finds probable cause, the defendant is generally “held to answer,” meaning the felony case can continue toward trial. If the prosecution’s evidence is legally insufficient, the court may dismiss charges or decline to hold the defendant to answer on particular counts.
Federal criminal cases use a similar early probable-cause process. A federal magistrate judge must dismiss the complaint and discharge the defendant when probable cause is not established, although dismissal does not necessarily prevent prosecutors from pursuing later charges.
Defense Advantages
A preliminary hearing can create meaningful defense advantages when approached strategically. One of the most valuable tools is early cross-exam. Defense counsel may question prosecution witnesses before trial, identify inconsistencies, and preserve testimony that could become important later.
This early scrutiny may reveal mistaken identification, gaps in a police investigation, conflicting witness accounts, or weak forensic evidence. It also gives the defense a clearer understanding of the prosecution’s theory and the evidence it intends to rely on.
A strong hearing can also create dismissal leverage. If the judge finds insufficient evidence on one or more charges, the prosecution may be forced to reduce or dismiss those allegations. Even when a case survives the hearing, testimony that exposes serious weaknesses can improve the defense’s position in plea negotiations or support later motions.
For example, California Penal Code section 995 permits a defendant to ask the trial court to set aside information when the defendant was committed without reasonable or probable cause. This makes the preliminary hearing record especially important.
It’s also important to understand how judges decide release or custody. A judge does not determine bail or pretrial release during a preliminary hearing. Bail, release conditions, and custody issues may be addressed separately based on the charges, the facts of the case, public-safety considerations, and the risk that a defendant may not appear in court.
A preliminary hearing may not decide guilt, but it can be the prosecution’s first real test. With an experienced criminal defense lawyer challenging the evidence early, it can become an opportunity to protect your rights, your freedom, and your future.
