If you’re wondering how they pick people for jury duty, the short version is this: a court’s computer pulls names at random from public records, mails those people a summons with a questionnaire, filters out anyone who doesn’t qualify, and then lets the judge and attorneys question the survivors in the courtroom until the right number of jurors remain for a specific case. Federal law requires the pool to represent a fair cross-section of the community, so the system casts a wide net early and narrows it in stages.
Where the Court Gets Your Name
Every federal court keeps a database called the master jury wheel. The primary source is voter registration or voting records within the court’s district, and each district must add at least one more source when voter rolls alone wouldn’t reflect the community.1Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection The most common addition is DMV records, which capture adults who have a license or state ID but aren’t registered to vote.
State courts work the same way in principle, though the specific lists differ. Some pull from tax rolls, utility records, or state ID databases alongside voter files. Merging several sources is deliberate: a single list would systematically miss people who don’t drive, don’t vote, or don’t own property.
Who Actually Qualifies to Serve
Being in the wheel is not the same as being eligible. Federal courts apply a short checklist before anyone is seated. You must be a U.S. citizen, at least 18 years old, and a resident of the judicial district for at least a year. You also have to read, write, speak, and understand English well enough to follow testimony and instructions.2United States Courts. Juror Qualifications, Exemptions and Excuses
Two groups are automatically disqualified: anyone with a felony conviction whose civil rights haven’t been restored, and anyone whose mental or physical condition would prevent adequate participation.2United States Courts. Juror Qualifications, Exemptions and Excuses State rules track these criteria with local variation.
Who Is Exempt or Can Be Excused
Three categories are exempt from federal jury service even when qualified:
- Members of the Armed Forces on active duty.
- Full-time members of a fire or police department at any level of government.
- Public officers in the executive, legislative, or judicial branches who are actively performing their duties.1Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection
Volunteer firefighters and rescue squad members can request to be excused under federal law. Beyond those statutory categories, each district’s jury plan lists other groups who can ask off for undue hardship or extreme inconvenience. Common grounds for an individual excusal include caretaking duties with no substitute, a medical condition that makes sitting through trial impractical, or financial hardship that daily pay wouldn’t offset. Most federal courts also let you defer through their online eJuror system and pick a later date rather than skip service entirely.3United States Courts. Summoned for Federal Jury Service
The Summons and Questionnaire
Once the computer pulls names, those people get a summons in the mail. It’s a legal order to appear, and it usually arrives with a juror qualification questionnaire asking about citizenship, age, residency, English proficiency, felony convictions, and any disqualifying condition. The court uses it to cut the raw list down to people who actually meet the requirements. You generally have ten days to return it, by mail or online.
Ignoring the questionnaire is a bad idea. A federal judge can order you to appear and explain why. If you can’t show a good reason, the penalty is a fine of up to $1,000, up to three days in jail, community service, or some combination.4Office of the Law Revision Counsel. 28 USC 1866 – Selection and Summoning of Jury Panels State penalties fall in a similar range.
Voir Dire in the Courtroom
Everyone who passes the questionnaire screening and reports to the courthouse becomes part of a larger group called the venire. This is still bigger than any single case needs. Voir dire is the in-court questioning that figures out who belongs on the final jury.
The judge usually asks the general questions first: whether anyone knows the parties or witnesses, whether anyone has been involved in a similar legal situation, whether anyone holds strong views about the kind of case being tried. The attorneys then follow with more targeted questions aimed at surfacing hidden biases or life experiences that could sway judgment. A personal injury lawyer might ask whether anyone works for an insurance company. A criminal defense attorney might probe how the group feels about eyewitness testimony. Voir dire can wrap in an hour for a straightforward civil matter or run several days in a high-profile criminal trial.
How Attorneys Remove Jurors
Attorneys have two tools during voir dire, and the difference between them explains why selection feels strategic.
A challenge for cause targets a specific, articulable reason the person can’t be fair. The prospective juror might be the defendant’s neighbor, might have publicly stated an opinion about the case, or might admit they can’t follow a particular instruction. There is no cap on these; if the judge agrees the person has a disqualifying bias or conflict, they’re out.5United States Courts. Participate in the Judicial Process – Rule of Law Judges grant these less freely than attorneys would like, which is why most of the real battle happens through the second mechanism.
Peremptory challenges let an attorney strike a juror without giving any reason. The number allowed depends on the case. In a federal civil trial, each side gets three.6Office of the Law Revision Counsel. 28 USC 1870 – Challenges Federal criminal cases work differently:
- Capital cases: each side gets 20.
- Other felonies: the prosecution gets 6 and the defense gets 10.
- Misdemeanors: each side gets 3.7Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors
There’s one firm limit on peremptory strikes. Attorneys cannot use them to remove jurors based on race or gender. The Supreme Court established the race rule in 1986, holding that the Equal Protection Clause bars prosecutors from challenging jurors solely on account of race.8Justia U.S. Supreme Court Center. Batson v. Kentucky, 476 U.S. 79 (1986) Eight years later it extended the same protection to gender-based strikes.9Legal Information Institute. J.E.B. v. Alabama ex rel. T.B., 511 U.S. 127 (1994) If one side suspects the other of discriminatory striking, they can raise a Batson challenge, and the judge will require a race- or gender-neutral explanation. Whoever remains after all the challenges becomes the sworn jury.
Grand Juries Follow a Different Path
If your summons is for a grand jury rather than a trial jury, selection starts the same way. Both types are drawn from the same master wheel and go through the same qualification process.4Office of the Law Revision Counsel. 28 USC 1866 – Selection and Summoning of Jury Panels After that, the experience diverges. A trial jury has 6 to 12 members and hears one case. A grand jury has 16 to 23 members, reviews multiple cases, and doesn’t decide guilt or innocence; it decides whether enough evidence exists to formally charge someone.10United States Courts. Types of Juries There is no voir dire for grand jurors in the trial-jury sense, because no single case is being tried.
What You Get Paid and What Your Job Owes You
Federal jurors earn $50 per day. If a trial runs past ten days, the judge can raise that to $60 per day for the remaining time, and jurors also get mileage reimbursement.11Office of the Law Revision Counsel. 28 USC 1871 – Fees State pay varies widely and in some places is nothing.
The paycheck from your actual job is usually the bigger concern. Federal law makes it illegal for any employer to fire, threaten, intimidate, or coerce a permanent employee because of jury service. A violation exposes the employer to liability for lost wages, a court order to reinstate the worker, and a civil penalty of up to $5,000 per violation. You’re entitled to return without loss of seniority, and your service counts as a leave of absence for benefits and insurance. If you need to bring a claim, the court can appoint an attorney to represent you at no cost.12Office of the Law Revision Counsel. 28 USC 1875 – Protection of Jurors Employment
