Voir dire is the jury selection phase of a trial, when the judge and the attorneys question prospective jurors under oath to identify anyone whose background, beliefs, or relationships would prevent them from deciding the case fairly. The phrase comes from Old French and roughly translates to “to speak the truth,” which captures the point of the exercise: people answer questions honestly so both sides can decide whom to keep and whom to remove.1U.S District Court. The Voir Dire Examination It happens in both civil and criminal cases, though how long it takes and how deep the questioning goes depends on what is at stake.
Where Voir Dire Fits in a Trial
Nothing else in the trial can begin until a jury is seated. The court summons a pool of prospective jurors, screens them, and from that pool the attorneys and judge build the panel that will hear the evidence. Voir dire is the screening. In a routine civil matter it can wrap up in a morning. In a complex or high-profile case it can stretch across days or even weeks.
How the Questioning Works
Screening usually starts before anyone walks into the courtroom. Courts send juror questionnaires with the summons, collecting occupation, education, prior contact with the legal system, and sometimes case-specific questions designed to surface obvious conflicts.2The Reporters Committee for Freedom of the Press. Secret Justice: Access to Juror Questionnaires In high-profile trials the questionnaires can run dozens of pages. Attorneys review them to build a preliminary picture of each person and to flag who they want to probe further.
Once the panel assembles in court, the prospective jurors are sworn in and the oral questioning begins. In federal civil cases, the judge has wide discretion over how this is run. Federal Rule of Civil Procedure 47 allows the judge to conduct the questioning personally, let the attorneys do it, or use some combination of both.3Legal Information Institute. Federal Rules of Civil Procedure Rule 47 – Selecting Jurors Some judges keep tight control and ask every question themselves. Others give lawyers substantial time to speak directly to the panel.
The questions in open court go deeper than anything on a form. A personal injury lawyer might ask whether anyone on the panel believes lawsuits have gotten out of hand. A criminal defense attorney might ask whether anyone assumes a person charged with a crime is probably guilty. These are not conversation starters. The answers decide who stays and who goes.
Removing a Juror for Cause
When a prospective juror reveals a concrete reason they cannot be impartial, either attorney can ask the judge to remove that person “for cause.” There is no cap on how many jurors can be struck this way. If ten people on a panel have disqualifying conflicts, all ten can go.4Office of the Law Revision Counsel. 28 US Code 1866 – Selection and Summoning of Jury Panels
For-cause challenges come in two forms. Actual bias is when a juror says outright that they cannot be fair. A person who says they would automatically believe a police officer over a civilian witness has stated actual bias. Implied bias comes from the juror’s relationship to the case: a close relative of the defendant, an employee of one of the law firms involved, or someone who is a party to related litigation would be removed regardless of what they claim about their own fairness.
The judge makes the final call on every for-cause challenge. Attorneys argue, but the judge decides whether the legal threshold has been met.
Peremptory Challenges
Peremptory challenges let attorneys remove prospective jurors without giving a reason. These are tactical. A lawyer might act on a gut feeling about someone’s answers, body language, or occupation. Unlike for-cause strikes, peremptory challenges come in a fixed number, and once they are used up they are gone.
In federal civil cases, each side gets three peremptory challenges. When multiple plaintiffs or defendants are involved, the court can either treat them as one side sharing those three or grant additional strikes.5Office of the Law Revision Counsel. 28 USC 1870 – Challenges Federal criminal cases provide more, scaled to the severity of the charge:6Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors
- Capital cases: 20 peremptory challenges per side.
- Other felonies: 6 for the government and 10 for the defendant.
- Misdemeanors: 3 per side.
The asymmetry in felony cases reflects that a defendant facing imprisonment typically needs more latitude in shaping the jury. Spend strikes too early and you may be stuck with someone worse later. Hold too many in reserve and you may run out of chances to use them.
What Peremptory Strikes Cannot Be Used For
Peremptory challenges are broad, but they are not unlimited. The Supreme Court has drawn a hard constitutional line: a juror cannot be struck because of race, ethnicity, or sex. Batson v. Kentucky established in 1986 that race-based peremptory strikes violate the Equal Protection Clause.7Justia U.S. Supreme Court Center. Batson v. Kentucky, 476 US 79 (1986) Eight years later, J.E.B. v. Alabama extended the same rule to strikes based on sex.8Justia U.S. Supreme Court Center. J.E.B. v. Alabama ex rel. T.B., 511 US 127 (1994)
How a Batson Challenge Works
When one side believes the other is striking jurors for a discriminatory reason, they raise what is called a Batson challenge. It moves through three steps.
The objecting party first has to show enough circumstances to raise an inference that the strike was based on race or sex. This is not a heavy burden. The pattern of strikes, the composition of the panel, and the questions asked can all contribute.
Second, the party that made the strike must offer a nondiscriminatory reason. The reason does not have to rise to the level that would justify a for-cause removal. Even a thin or idiosyncratic explanation can satisfy this step, as long as it is not inherently discriminatory and not simply a restatement of a stereotype.7Justia U.S. Supreme Court Center. Batson v. Kentucky, 476 US 79 (1986)
Third, the judge decides whether the stated reason is genuine or a pretext. This is a credibility determination, and it is where most Batson challenges are won or lost. The judge weighs the attorney’s demeanor, the plausibility of the explanation, and whether the same reason was applied consistently to jurors of different backgrounds. In Flowers v. Mississippi, the Supreme Court emphasized that a prosecutor’s history across multiple trials, disparate questioning of jurors of different races, and implausible explanations can all support a finding of discrimination.9Justia U.S. Supreme Court Center. Flowers v. Mississippi, 588 US ___ (2019)
If the judge finds a Batson violation, the usual remedies are to seat the improperly struck juror or to dismiss the panel and start over. A single discriminatory strike is enough to trigger reversal on appeal.
If You Are the One Being Summoned
People who receive a jury summons sometimes assume they can throw it away. In the federal system, failing to appear can result in a fine of up to $1,000, up to three days in jail, community service, or a combination of all three.10Office of the Law Revision Counsel. 28 USC 1864 – Drawing of Names from the Master Jury Wheel The same penalties apply to anyone who lies on the qualification form to get out of service or to secure a seat. State courts set their own penalties, and some are steeper.
Lying during voir dire itself is just as serious. If a juror’s dishonesty is discovered after trial, it can be grounds for overturning the verdict and forcing a new one. The whole system runs on honest answers from the pool. If you have a genuine hardship, say so to the court. Don’t ignore the summons, and don’t misrepresent your situation to shape the outcome.
