Voir dire is the pretrial questioning of prospective jurors that lets the judge and the attorneys decide who is fit to sit on a jury. The term comes from Old French and roughly translates as “to speak the truth.” Through a mix of direct questions and formal legal challenges, voir dire filters out people whose biases, relationships, or personal experiences would keep them from weighing the evidence objectively.
How the Questioning Works
A group of prospective jurors is brought into the courtroom. The judge usually opens by describing the case, introducing the parties and their lawyers, and laying out the ground rules. Then the questions begin.
Who does the asking depends on the court. In federal civil cases, the judge may question jurors directly, let the attorneys handle it, or do some combination of both. When the judge runs the initial round, the attorneys can follow up with any additional questions the court considers appropriate.1Legal Information Institute / Cornell Law School. Federal Rules of Civil Procedure Rule 47 – Selecting Jurors Many federal judges prefer to do most of the questioning themselves, sometimes working from questions the lawyers submit in advance. State courts vary. Some give attorneys broad latitude to question jurors directly for extended periods; others keep the process tightly controlled from the bench. Research on jury selection has consistently found that jurors tend to open up more when attorneys ask the questions than when the judge does, likely because the authority of the bench makes people more guarded.
For a routine case, voir dire often wraps up in a couple of hours. Complex or high-profile trials are different. Capital cases in particular can spend more time on jury selection than on the trial itself, sometimes stretching across weeks as attorneys probe each juror’s views on the death penalty and other sensitive topics.
What Prospective Jurors Are Asked
Voir dire questions are designed to reveal anything that might interfere with a juror’s ability to be impartial. Attorneys and judges ask about occupation, personal background, prior experiences with the legal system, and views on topics relevant to the case. In a personal injury lawsuit, a lawyer might ask whether anyone on the panel has been in a similar accident or holds strong opinions about frivolous lawsuits. In a criminal drug case, the questions might explore whether a juror has a family member who struggled with addiction.
Good voir dire questions are open-ended. Rather than asking “Can you be fair?” (to which almost everyone says yes), experienced attorneys ask things like “What comes to mind when you hear someone has been charged with fraud?” or “Tell me about a time you felt the legal system got something wrong.” These prompts get jurors talking in ways that reveal genuine attitudes rather than rehearsed assurances of impartiality.
In some cases, courts supplement oral questioning with written questionnaires sent to prospective jurors before they arrive in the courtroom. Questionnaires cover ground that would otherwise eat up live questioning time and are especially common in high-profile cases where pretrial publicity is a concern. They let attorneys identify jurors who have already formed opinions about the case before oral voir dire begins.
Challenges for Cause
When questioning reveals that a prospective juror cannot be impartial, an attorney asks the judge to remove that person through a challenge for cause. The attorney must point to a specific, legally recognized reason. Common grounds include an obvious bias toward one side, a personal relationship with a party or witness, prior knowledge of the facts of the case, or a stated inability to follow the law as instructed.
The judge decides whether the reason is sufficient. If the challenge is granted, the juror is dismissed and replaced. There is no cap on how many challenges for cause either side can raise. As long as you can articulate a legitimate reason and the judge agrees, you can keep going.
Peremptory Challenges
Peremptory challenges let attorneys remove prospective jurors without giving any reason at all. Each lawyer gets a fixed number of these strikes, and they are the primary tool for shaping the jury’s composition based on gut instinct, trial strategy, or concerns that fall short of a provable bias.
In federal criminal cases, the number of peremptory challenges depends on the severity of the charges:
- Capital cases: each side gets 20 peremptory challenges.
- Other felonies: the prosecution gets 6 and the defense gets 10.
- Misdemeanors: each side gets 3.
The imbalance in felony cases is intentional. Because a criminal defendant’s liberty is at stake, the defense receives more strikes.2Cornell Law Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors
In federal civil cases, each side receives three peremptory challenges. When multiple plaintiffs or defendants are involved, the court can treat them as a single party for strike purposes or grant additional challenges.3Office of the Law Revision Counsel. 28 US Code 1870 – Challenges State courts set their own numbers, which typically range from three to six per side in civil trials and can be higher in criminal matters.
Limits on Peremptory Strikes
Because peremptory challenges require no justification, attorneys could in principle use them to systematically exclude jurors based on race, gender, or ethnicity. The Supreme Court has spent decades closing that loophole.
The Batson Framework
In Batson v. Kentucky (1986), the Supreme Court held that the Equal Protection Clause forbids prosecutors from challenging potential jurors solely on account of their race.4Legal Information Institute / Cornell Law School. Batson v Kentucky, 476 US 79 The Court set out a three-step process for evaluating whether a strike is discriminatory:
- The party objecting to the strike must show that the circumstances raise an inference of discrimination. This burden is deliberately low.
- If that threshold is met, the attorney who made the strike must offer a race-neutral reason. The explanation does not need to be persuasive, but it must be specific enough that the court can evaluate it. Simply denying discriminatory intent is not enough.
- The trial judge then decides whether the objecting party has proven intentional discrimination, weighing the credibility of the explanation against the overall pattern of strikes.
Beyond Race
In J.E.B. v. Alabama (1994), the Court extended the Batson framework to gender, holding that “gender, like race, is an unconstitutional proxy for juror competence and impartiality.”5Legal Information Institute / Cornell Law School. JEB v Alabama Ex Rel TB, 511 US 127 In Flowers v. Mississippi (2019), where the prosecution struck 41 of 42 Black prospective jurors across six trials of the same defendant, the Court emphasized that a prosecutor’s full history of strikes is relevant when evaluating a Batson challenge.
Critics have long argued that the Batson framework is too easy to satisfy at step two, since nearly any explanation short of an explicit admission of bias can be characterized as race-neutral. Arizona eliminated peremptory challenges entirely in 2022. Washington adopted a rule that replaces the requirement of proving intentional discrimination with an “objective observer” standard, asking whether a reasonable person aware of implicit and institutional bias could view race as a factor in the strike. California, Connecticut, and New Jersey have also overhauled their approaches.
What Happens If a Juror Lies
Prospective jurors are under oath during voir dire, and lying carries real consequences. The most immediate risk is to the trial itself. Under the Supreme Court’s standard in McDonough Power Equipment v. Greenwood, a party can obtain a new trial by showing that a juror failed to answer a material question honestly and that a truthful answer would have provided a valid basis for a challenge for cause.6Legal Information Institute / Cornell Law School. McDonough Power Equipment Inc v Greenwood, 464 US 548 Both elements matter. A juror who innocently misunderstood a question, or whose dishonest answer would not have changed the outcome, does not trigger a new trial under this test.
Beyond the verdict, a dishonest juror can face criminal charges. Federal perjury law applies to anyone who willfully makes a false statement under oath in a court proceeding, and a conviction carries up to five years in prison.7Office of the Law Revision Counsel. 18 USC Ch 79 – Perjury A judge can also hold a dishonest juror in contempt of court, resulting in fines or jail time imposed on the spot. Courts have prosecuted jurors who concealed criminal histories, personal relationships with parties, or prior lawsuit experience during voir dire.
Who Is Eligible to Serve in the First Place
Voir dire is the second screen. Before anyone sits in the jury box to be questioned, prospective jurors must already meet basic eligibility requirements. Federal courts require that a juror be a United States citizen, at least 18 years old, and a resident of the judicial district for at least one year. Jurors must be able to read, write, and speak English adequately, and cannot be currently facing felony charges or have a prior felony conviction unless their civil rights have been restored.8United States Courts. Juror Qualifications, Exemptions and Excuses People who meet these basic requirements but have disqualifying mental or physical conditions that cannot be reasonably accommodated may also be excluded. State courts generally impose similar requirements, though the specifics vary. Voir dire then does the finer work: not just whether someone is legally eligible to serve, but whether they can be fair in this particular case.
