In jury duty, a panel is the group of prospective jurors pulled from the day’s larger jury pool and sent into one courtroom, where the judge and attorneys will question them to choose the actual jury for a single trial. Being assigned to a panel does not mean you are on the jury. It means you are in the running to be on it. Most people who report for jury duty spend the day in the general assembly room; only some are ever called to a panel, and only a fraction of panel members end up seated as jurors.
Pool, Panel, and Jury Are Three Different Things
The three words sound interchangeable, and courts sometimes use them loosely, but they describe a funnel.
The jury pool is the wide opening: everyone who showed up at the courthouse that day in response to a summons. The panel, sometimes called a venire, is the narrower middle: a subset of the pool directed to one specific courtroom for one specific case. The seated jury is the narrow end: the people actually chosen to hear that case.
A routine criminal case might draw a panel of 30 to 50 people. A high-profile or sensitive case can pull a much larger panel because the attorneys expect to eliminate more people during questioning. In federal criminal trials, the seated jury is 12 unless both sides agree in writing to fewer.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 23 – Jury or Nonjury Trial Federal civil juries must start with at least 6 and no more than 12.2Legal Information Institute.

How You End Up on a Panel
Your day begins in the jury assembly room with everyone else who reported that morning. Court staff use random selection software to pull names or juror numbers whenever a judge is ready to start a trial. When your name comes up, you gather your things and follow a court officer to a courtroom. That walk is the moment you cross from the general pool into an active panel.
The randomness is deliberate. Courts are required to use random selection at each stage — summoning, panel assignment, and courtroom seating — so that no one can hand-pick a favorable group and so that panels reflect a genuine cross-section of the community.
Before any of this, you’ll fill out a juror questionnaire covering your job, education, past contact with the legal system, and any connection to people involved in the case. Those answers give the judge and the attorneys a starting point for the questioning that happens once the panel is in the courtroom.
What Happens Once Your Panel Is in the Courtroom
After the panel is seated in the courtroom, the judge begins voir dire, the questioning process used to uncover bias.3United States Courts. Juror Selection Process The phrase is Old French and roughly means “to speak the truth.” The court clerk calls panel members into the jury box a few at a time for closer questioning.
The judge usually opens with a short description of the case and introduces the attorneys and parties. For most panel members, this is the first time they learn what the trial is about. Then come the questions: your work, your family, your experiences with crime or lawsuits, and whether anything in your life might make it hard to be objective in this particular case. Some questions feel personal, and the judge will often let you answer sensitive ones privately rather than in open court. Panel members take an oath to answer truthfully.4U.S. District Court Southern District of New York. The Voir Dire Examination
How Attorneys Remove People from the Panel
Voir dire exists so attorneys can decide who they want off the panel. They have two tools for doing it.
A challenge for cause is an argument that a specific panel member cannot be impartial, usually because of a personal connection to the case or a stated bias. The judge decides whether to grant it. There is no limit on how many for-cause challenges either side can raise.4U.S. District Court Southern District of New York. The Voir Dire Examination
A peremptory challenge lets an attorney remove a panel member without giving a reason. These are capped. In federal criminal cases, the defense gets 10 peremptory challenges for felonies and the prosecution gets 6; in misdemeanor cases each side gets 3; in capital cases each side gets 20.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors
Peremptory challenges have one firm limit beyond the numerical cap. The Supreme Court has held that attorneys cannot use them to exclude jurors based on race or gender. The racial prohibition was established in 1986, and the same protection was extended to gender-based strikes in 1994.6United States Courts. Facts and Case Summary – JEB v Alabama If a panel member appears to have been struck for a discriminatory reason, the judge can require the attorney to give a neutral explanation.
The challenges continue until the required number of jurors remains. Those who survive are formally sworn in. At that point you stop being a panel member and become a juror.
Alternates Come From the Same Panel
In addition to the regular jurors, the court can seat up to six alternates from the same panel. Alternates go through the same selection process, sit through the whole trial, and step in only if a regular juror gets sick, has an emergency, or is disqualified.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors If an alternate replaces a juror after deliberations have already begun, the jury has to start deliberating over from the beginning.
If Your Name Is Never Called to a Panel
Many courts follow a “one day or one trial” model. If you report to the assembly room and your name is never called to join a panel by the end of the day, your service is complete and you go home. If you are called to a panel but not selected for the jury during voir dire, you’re typically sent back to the assembly room, and if no other panels need you, you’re released then.
So the panel assignment is the real fork in the road. Without one, your time in the assembly room is the whole obligation. With one, you move into the active selection process in a courtroom.
Grand Jury Panels Are a Different Animal
The word “panel” also applies to grand juries, and the commitment is nothing alike. A grand jury panel consists of 16 to 23 people who meet regularly over a period that can run up to 18 months, with extensions possible to 24 months.7United States Courts. Types of Juries Grand jurors don’t decide guilt. They review evidence from prosecutors and decide whether there’s enough to bring charges. If your summons specifically says “grand jury,” you’re looking at a much longer commitment than the trial panel described above.
