Juror Meaning
A juror is an individual selected to serve on a Jury. The person's legal job depends on the proceeding: a trial juror helps decide a case, while a grand juror helps decide whether a criminal accusation should proceed. A summons for possible service, an indictment, and a trial verdict therefore describe different stages and responsibilities.
That distinction matters if you receive a court notice or read that a grand jury has indicted someone. Being summoned does not mean you have been seated on a case, and being indicted does not mean a person has been convicted. The federal examples below explain the differences. State qualifications, selection procedures, jury sizes, and voting rules can differ; the actual court's instructions govern a person serving there.
What does each kind of juror decide?
The U.S. Courts' explanation of jury types distinguishes petit, or trial, juries from grand juries. Trial jurors decide factual issues under the law the judge explains. They do not independently choose a legal rule from a dictionary or website.
Juror's setting | Task, evidence and possible result |
|---|---|
Federal criminal trial | Jurors consider evidence admitted at trial, with prosecution and defense able to present their positions. The government must prove the charged crime beyond a reasonable doubt. The jury returns a guilty or not-guilty verdict; the defendant does not have to present evidence to make the prosecution meet its burden. |
Federal civil trial | Jurors decide disputed factual issues concerning the civil claim and any required relief. The parties present evidence. Preponderance of the evidence, meaning more likely than not, is a common standard, but the particular claim and the judge's instructions determine the applicable burden. A civil verdict is not a criminal conviction. |
Federal grand jury | Jurors investigate possible federal crimes, ordinarily hearing evidence presented by a government attorney and witnesses rather than a two-sided trial presentation. They decide probable cause for an indictment, not guilt beyond a reasonable doubt. An indictment is a formal accusation. |
Probable cause and proof beyond a reasonable doubt answer different questions. A grand jury considers whether the evidence justifies a criminal charge. A criminal trial jury decides whether the government has proved guilt under the much higher trial standard. Neither the grand jury's existence nor its decision substitutes for the trial jury's work.
The federal Grand Juror Handbook describes an indictment as a “true bill.” When the evidence does not persuade the grand jury that probable cause exists, its decision is called a “no bill” or “not a true bill.” Those terms concern the charging decision; they are not alternative names for a trial conviction or acquittal.
From a summons to a trial jury seat
The federal selection process separates drawing names from choosing jurors for a particular trial. A useful way to read your paperwork is to identify the stage:
- Names enter the selection pool. Federal courts draw randomly using voter lists and, when needed to obtain a representative community cross section, additional sources such as driver's-license lists. This is a pool for possible service, not a decision that a named person will hear a particular dispute.
- The court checks qualifications. A questionnaire supplies information for qualification decisions. Federal requirements include citizenship, age, residence, language ability, and other statutory conditions. The court's qualifications and excuses guide also addresses accommodations, exemptions, hardship requests, and local procedures. A request for an excuse is different from the court granting it.
- Summoned people report as instructed. Reporting may place a qualified person in the group available for trials. It does not guarantee a seat. Follow the particular notice's dates and response instructions; this glossary cannot grant a postponement or excuse.
- Potential trial jurors undergo voir dire. The judge, attorneys, or both ask questions to identify suitability and possible bias in the particular case. Relevant relationships, prior knowledge, and inability to follow instructions should be disclosed honestly. Answer the court's actual questions rather than trying to engineer a particular result.
- The selected jurors are sworn or affirm. After screening and challenges, the people selected for the trial take the required oath or affirmation. The Petit Jury Handbook explains this transition from prospective panel member to juror deciding the case.
Federal grand-jury selection also uses a randomly selected community pool and legal qualifications, but it is not selection of a trial jury for one defendant's two-sided trial. The Grand Juror Handbook describes the court considering excusal requests, selecting qualified members, appointing a foreperson and deputy, administering the oath or affirmation, and charging the grand jury with its duties. Grand jurors may consider multiple investigations during their service.
Voir dire and challenges are different steps
A challenge for cause asks the court to excuse a prospective trial juror for a sufficient reason, such as inability to remain impartial. The judge decides whether the stated cause warrants removal. A peremptory challenge permits a limited number of removals without the ordinary showing of cause.
Peremptory does not mean an unrestricted right to discriminate. The federal courts' criminal-trial guide explains objections to exclusions based on race, ethnicity, or gender. Nor is there one challenge allowance for every proceeding: Federal Criminal Rule 24 sets different numbers by case type, while 28 U.S.C. § 1870 addresses civil challenges and multi-party flexibility.
Being excused by a challenge is not a finding that the prospective juror is dishonest or unfit for every future jury. It concerns selection in that proceeding. Grand-jury objections, governed by Criminal Rule 6(b), address lawful selection or legal qualification; do not assume trial peremptory-challenge procedures apply unchanged to a grand jury.
Juror duties include limits on outside information
Trial jurors listen to admitted testimony, examine exhibits, evaluate factual disagreements, deliberate when instructed, and apply the court's law. They bring ordinary experience and common sense, but do not conduct a private investigation. The Petit Jury Handbook expressly addresses outside websites, news, dictionaries, scene visits, electronic communication, and discussion with family or others. If outside information reaches a juror during trial, the handbook instructs the juror to tell the court rather than share it in the jury room.
If you are serving on a jury, ask the judge through the court's prescribed process about a legal term. This glossary is not permission to research a live case, consult an AI tool about its evidence, or replace the instructions given in court.
Grand jurors have a distinct secrecy obligation. Federal Criminal Rule 6 restricts disclosure of matters occurring before the grand jury, subject to specified exceptions. It also limits who may attend sessions and excludes the government attorney from deliberations and voting. Do not translate that into a statement that every witness automatically has precisely the same secrecy duty as a grand juror; the rule identifies who is bound and the permitted disclosures.
An indictment and a verdict can differ without contradiction
Imagine a federal grand jury hears witness testimony and records supporting a fraud accusation. If the required jurors find probable cause, it may return an indictment. The news headline reports a charge, not established guilt.
If that charge later goes to a jury trial, a different jury considers the admitted trial evidence under the judge's instructions. The defense may challenge testimony and the government must prove guilt beyond a reasonable doubt. A not-guilty verdict can follow even though the earlier probable-cause decision allowed a charge. These are different decisions on different standards and presentations, not proof that the jurors performed the same task inconsistently. This is an illustrative sequence, not a prediction that every indictment necessarily results in a trial.
Common questions about jurors
Are there always 12 jurors? No. In federal criminal trials, Rule 23 starts from 12 but provides specified smaller-jury exceptions. Federal Civil Rule 48 starts a civil jury with 6 to 12 members. A federal grand jury has 16 to 23 members under Rule 6. These are federal rules, not a nationwide description of every state proceeding.
Do all jurors have to agree? Federal Criminal Rule 31 requires a unanimous trial verdict. Federal Civil Rule 48 requires unanimity unless the parties stipulate otherwise. A federal grand jury may indict with at least 12 jurors concurring; unanimity of all members is not required. Do not use the grand-jury voting threshold to interpret a trial verdict.
How likely am I to be selected? There is no reliable universal percentage. Random selection into the pool, legal qualifications, court scheduling, requests for excuse, and case-specific screening are separate stages. A summons alone cannot tell you that you will sit on a particular case. Contact the court named on the notice for its reporting procedures.
How much are federal grand jurors paid? The U.S. Courts' current pay guide lists $50 per day of service and eligibility for up to $60 after 45 days. Federal employees receive regular salary instead of that fee; certain travel reimbursements and allowances may also apply. State rates and employer salary policies are separate questions. Check the issuing court's current information rather than assuming that rate applies everywhere.
