A probable cause conference is an early hearing in a felony case where your attorney and the prosecutor meet to discuss the evidence, explore a plea agreement, and raise any bond issues before the case moves to a preliminary examination. It happens after arraignment but before any formal evidentiary hearing, and its purpose is practical: resolve the case early if possible, or at least narrow what has to be litigated later. Procedures vary by jurisdiction, but the function is the same wherever this step exists.
The conference itself does not decide whether probable cause exists. That determination comes later, at the preliminary examination. The conference is the informal step where the attorneys figure out whether the case can be resolved before anyone has to litigate that question.
When the Conference Is Scheduled
A probable cause conference is typically set within one to three weeks after arraignment. The exact timing depends on local court rules and whether you are in custody. Under federal rules, a preliminary hearing must occur within 14 days of the initial appearance if the defendant is in custody and within 21 days if released.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 5.1 – Preliminary Hearing Because the conference is scheduled before that examination, it falls inside those windows. Many courts set it about seven to fourteen days after arraignment.
Those timelines can be extended if both sides agree or if the court finds extraordinary circumstances. When a defendant hasn’t consented to a delay and is sitting in jail, courts generally stick close to the deadlines.
Who Will Be There
The main participants are the prosecuting attorney, your defense attorney, and you. A judge is available at the courthouse but doesn’t always sit in on the conference itself. The judge’s role is to handle any formal actions that come out of the discussion: accepting a plea agreement, modifying bond conditions, or scheduling future court dates.
The actual negotiations between the prosecutor and defense attorney often happen privately, outside the courtroom and off the record. You are required to be at the courthouse and available, but you may not always be in the room during those discussions. Your attorney should brief you before and after every conversation with the prosecutor so you know what’s being proposed and can make informed decisions about how to proceed.
Your Right to an Attorney
The Sixth Amendment guarantees the right to counsel at all critical stages of a criminal prosecution, which begins once formal proceedings have started through a charge, arraignment, or indictment.2Constitution Annotated (congress.gov). Sixth Amendment – Right to Counsel A probable cause conference falls squarely within that window. If you cannot afford a private attorney, you have the right to request a court-appointed one, and many courts handle that appointment at or shortly after arraignment, so counsel should already be in place by the time the conference arrives.
This is not a stage to handle on your own. The conference involves plea negotiations, evidence discussions, and strategic decisions that directly shape what happens in your case. Walking in without an attorney means walking in without anyone who can evaluate the strength of the prosecution’s evidence, push back on charges, or negotiate on your behalf.
What Actually Happens
The conference is less formal than most people expect. No testimony. No witnesses. The rules of evidence don’t apply. It’s a working meeting between attorneys.
Your defense attorney reviews whatever evidence the prosecution intends to use: police reports, witness statements, forensic findings, surveillance footage. The goal is to get a realistic picture of how strong the case is. Experienced defense attorneys look for weaknesses early, whether that’s an inconsistent witness statement, a procedural misstep during the investigation, or a gap between what the police report says and what the physical evidence shows.
A significant portion of the conference involves plea negotiations. The prosecutor may offer a deal that reduces the charges, recommends a lighter sentence, or drops some counts in exchange for a guilty plea. At this early stage, offers tend to be more favorable than what comes later. Prosecutors know trials are expensive and time-consuming, and defense attorneys know that the further a case progresses, the more entrenched both sides become. This is often the best window for resolving a case on favorable terms.
Evidence You’re Entitled To
The prosecution has a constitutional duty under Brady v. Maryland to turn over evidence that is favorable to the defense, whether it relates to guilt or sentencing.3Justia U.S. Supreme Court. Brady v. Maryland, 373 U.S. 83 (1963) If the prosecution has evidence that could help your case, they cannot sit on it. The rule applies regardless of whether the prosecutor is acting in bad faith.
In practice, the scope and timing of disclosure vary by jurisdiction. Some states require the prosecution to hand over most materials before or at the conference. Others operate on a more limited timeline. Your defense attorney can file discovery requests to push for access to police reports, lab results, witness lists, and other materials the prosecution holds. The conference is often the first chance to identify what evidence exists and to start demanding anything that hasn’t been provided yet.
How It’s Different From a Preliminary Examination
People often confuse the two, but they serve very different purposes.
The conference is informal. Attorneys talk, often privately, no witnesses testify, and nobody makes a legal determination about probable cause. It’s a negotiation and case-management session.
The preliminary examination is a formal evidentiary hearing. The prosecution calls witnesses and presents evidence. The defense can cross-examine those witnesses and introduce its own evidence. A judge then decides whether there’s enough probable cause to send the case to trial. If the judge says no, the complaint is dismissed and the defendant is released, though the government can still refile charges later.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 5.1 – Preliminary Hearing
The conference comes first. If it doesn’t resolve the case, the preliminary examination follows.
Possible Outcomes
A probable cause conference can end several different ways.
- Plea agreement. If the prosecution and defense reach a deal, the judge can accept the plea at the conference. The case then moves directly to sentencing, skipping the preliminary examination and trial entirely. This is the most common resolution for less serious felonies when the evidence is strong.
- Case proceeds to preliminary examination. If no deal is reached, the court schedules that hearing, where a judge evaluates whether probable cause exists to send the case to a higher court for trial.
- Grand jury indictment. In some jurisdictions, the prosecution can bypass the preliminary examination entirely by presenting the case to a grand jury. If the grand jury indicts, the case moves forward without a judicial probable cause finding.
- Dismissal. In rare situations, the prosecution may drop the case at this stage if the evidence falls apart or a legal defect surfaces. Uncommon, but it happens.
Bond conditions can also be modified during the conference. If your attorney believes bail is set too high or that certain conditions are unnecessary, the conference is a natural opportunity to raise those arguments with the judge.
Waiving the Preliminary Examination
During or after the conference, your attorney may discuss whether to waive the preliminary examination. Waiving means you agree to skip the hearing and allow the case to move directly to the trial court. It is not an admission of guilt. It simply means you’re foregoing the right to challenge probable cause at that stage.
There are reasons to consider it. If the evidence against you is strong and likely to survive the hearing anyway, a waiver can speed things up and let your attorney focus resources on trial preparation rather than a hearing that probably won’t change the outcome. A waiver can also be part of a broader negotiation strategy, offered in exchange for a concession from the prosecution.
The tradeoff is real. The preliminary examination is one of the few opportunities to see prosecution witnesses testify under oath before trial. It lets your attorney test their credibility, lock in their testimony, and identify inconsistencies that can be exploited later. Waiving that hearing means giving up that preview. For cases where the evidence is thin or the witnesses are shaky, that’s a significant sacrifice. Don’t waive the preliminary examination without a clear strategic reason discussed with your attorney.
What Happens If You Miss It
Skipping a probable cause conference triggers immediate consequences. The judge will almost certainly issue a bench warrant for your arrest, meaning law enforcement can pick you up anywhere, at any time. You could be taken into custody during a traffic stop, at your home, or at your workplace.
Beyond the warrant, failing to appear can result in additional criminal charges. Many jurisdictions treat it as a separate offense, and penalties often mirror the severity of the underlying case. If you were out on bail, the court can revoke it entirely and hold you in jail for the remainder of the proceedings. If you were released on your own recognizance, the judge can impose a cash bond as a condition for any future release. Fines and jail time for the failure to appear can stack on top of whatever sentence comes from the original charges.
If you genuinely cannot make a court date due to an emergency, contact your attorney immediately. Courts can sometimes reschedule, but only if you raise the issue before the hearing, not after. Once a bench warrant has issued, unwinding the situation becomes much harder and more expensive.
How to Prepare
Preparation starts with your attorney. Before the conference, make sure your lawyer has a complete picture of your situation. Bring any documents they’ve requested: employment records, medical information, character references, proof of community ties. These aren’t background filler. They can directly influence bond arguments and sentencing negotiations if a plea deal is on the table.
Ask your attorney what the prosecution’s evidence looks like and how strong the case appears. Understand the charges against you, the potential penalties, and the range of outcomes your attorney considers realistic. If a plea offer is likely, decide what you’d be willing to accept before the conference, not during it. Defendants who wait until they’re standing in the courthouse hallway to think about whether they’ll take a deal tend to make worse decisions under pressure.
Dress appropriately, arrive early, and bring identification. Courthouses have their own pace, and your attorney may need to speak with the prosecutor, check in with the clerk, and meet with you before anything starts. The more time you give yourself, the less stressful the morning will be.
