What Happens at a Preliminary Hearing in Wisconsin?

A preliminary hearing in Wisconsin is a court proceeding where a judge decides whether there is enough evidence to send a felony charge forward to trial. No one is found guilty or not guilty. The judge answers one question: is there probable cause to believe a felony was committed and that you committed it? The standard favors the prosecution, so most cases clear it, but the hearing still gives your defense a real early look at the state’s case.

When You Get a Preliminary Hearing

Preliminary hearings apply only to felony charges. Misdemeanor cases skip this step and head straight toward trial or plea negotiations.

Timing depends on custody status. If you are in custody and your bail has been set above $500, the hearing must begin within 10 days of your initial appearance. If you have been released, the deadline is 20 days.¹ Either side can ask for more time, and a judge can grant an extension for good cause or when both parties agree.

What the Judge Is Deciding

Probable cause is a specific legal standard, and it is deliberately lower than the “beyond a reasonable doubt” standard used at trial. Wisconsin’s pattern jury instructions describe it as facts, and reasonable inferences from those facts, that would lead a reasonable person to conclude a felony was probably committed and that you probably committed it.² The prosecution does not need to prove its whole case. It needs to show enough to justify moving forward.

The judge also does not weigh witness credibility at this stage. If a witness tells a plausible story that, taken at face value, supports the charge, the judge will generally accept it. Whether that witness is actually trustworthy is a question for a jury at trial. Wisconsin courts have applied this rule consistently since State v. Dunn in 1984.

What Happens in the Courtroom

The prosecution goes first. In many cases that means a law enforcement officer takes the stand and summarizes the investigation, though the state can call other witnesses too. Everyone testifies under oath, and a court reporter records the testimony.¹

Your attorney can cross-examine every witness the state calls. This is one of the hearing’s most useful features. Cross-examination lets the defense probe inconsistencies, pin witnesses down on details the prosecution might later want to adjust, and get a preview of how the state intends to build its case at trial.

You also have the right to call your own witnesses, who would then face cross-examination by the prosecution.¹ Most defense attorneys choose not to. Putting on your own evidence this early can reveal defense strategy without much upside, since the probable cause standard already tilts toward the state. The option is there, though, and sometimes it makes tactical sense.

The Two Possible Outcomes

Bindover for Trial

If the judge finds probable cause, you are “bound over” for trial and the case advances to the next phase. A guilty plea cannot be accepted until after bindover or waiver of the preliminary hearing, so this step is a required gateway in every Wisconsin felony prosecution.¹

Discharge or Partial Dismissal

If the judge does not find probable cause, the court must order you discharged. When a complaint contains multiple counts, the judge looks at each one separately. Any count that lacks probable cause gets dismissed, and the remaining counts move forward. Facts from a dismissed count cannot be used as the basis for new charges in any information filed later.¹

A dismissal here does not always end the matter. Wisconsin law allows the prosecution to seek a second preliminary hearing, and a dismissal does not strip the prosecutor of discretion to pursue the case again if new or additional evidence surfaces.³

What Comes Next After Bindover

Once you are bound over, the district attorney has 30 days to file a formal charging document called an “information.” This document sets out the charges supported by the evidence from the hearing. If the DA misses that window, you can ask the court to dismiss the case, though that dismissal is without prejudice and charges could potentially be refiled.⁴

After the information is filed, the next step is arraignment. The district attorney gives you a copy of the information, the charges are read aloud unless you waive the reading, and the court asks for your plea.⁴ At that point the case has formally entered the trial track.

Should You Waive the Hearing?

You can waive your right to a preliminary hearing. It is a strategic decision, not a default, and it should be made with your attorney. The waiver form used in Wisconsin courts spells out what you give up: the right to question the state’s witnesses, the right to present your own evidence, and the chance to learn about possible defenses.⁵

There are legitimate reasons to waive. If plea negotiations are already underway and both sides are close to a deal, the hearing can feel like a formality that slows things down. Some defendants prefer to keep potentially damaging testimony out of a public courtroom before trial. And because the probable cause standard favors the prosecution, dismissals at this stage are uncommon, which can make waiver feel like a low-cost trade.

The downside is real. A preliminary hearing is one of the few early opportunities to lock witnesses into sworn testimony. If a witness changes their story later, that recorded testimony can be powerful at trial. Waiving also means you skip the chance to see how the prosecution’s case fits together before making major decisions about your defense. Many experienced defense attorneys treat the hearing as an investigative tool, not just a probable cause checkpoint. Once you waive, the case moves directly to the information and arraignment.⁵

Closed Hearings in Sensitive Cases

Preliminary hearings are generally open to the public. Wisconsin law lets the judge close the courtroom in cases involving sexual assault, child exploitation, and related offenses. Either side can ask for closure, and the judge will grant it if an open hearing would seriously harm a compelling interest, such as protecting a victim from unnecessary emotional trauma. Any closure order must be as narrow as possible, and the judge has to put specific findings on the record explaining why it is necessary.¹
