Voir dire is a legal procedure where judges and lawyers question people (or sometimes witnesses) to decide if they are suitable and fair for a trial. It literally comes from French meaning “to speak the truth.”

What is voir dire? (Quick Scoop)

  • It is most commonly the jury selection process, where potential jurors are questioned about their backgrounds, beliefs, and possible biases.
  • The goal is to ensure a fair and impartial jury that can decide the case based only on the evidence and the law.
  • In some systems, voir dire can also involve questioning witnesses (especially experts) to test whether they are competent or qualified to testify.
  • The term is rooted in common law and is widely used in countries like the United States and others that follow similar legal traditions.

How voir dire works in practice

During jury selection, lawyers and sometimes the judge ask potential jurors questions such as:

  • Whether they have heard about the case in the news or online.
  • Whether they have strong opinions about issues central to the case (for example, criminal justice, personal injury claims, or law enforcement).
  • Whether anything in their background (work, family experiences, prior cases) might make it hard to be neutral.

If a juror appears biased or unable to follow the court’s instructions, they can be removed:

  • Challenge for cause : A lawyer explains a specific reason the juror cannot be fair (for example, open prejudice or a clear conflict of interest).
  • Peremptory challenge : A lawyer asks to excuse a juror without giving a reason, though they cannot legally use this to discriminate based on race or gender.

Beyond juries: witnesses and evidence

  • Voir dire can be used to question an expert witness about their education, training, and experience before the judge decides if they may give opinion testimony.
  • In some countries (especially common-law jurisdictions outside the US), a voir dire can be like a “trial within a trial” used to decide whether a piece of evidence is admissible or whether a statement was given voluntarily.

Example: In Canada and other Commonwealth systems, a voir dire may be held to determine whether a confession to police was made freely, before the jury is allowed to hear it.

Why voir dire matters now

  • In high-profile or heavily online-discussed cases, many potential jurors come in with strong opinions or prior exposure to media coverage, making careful voir dire essential to filter out serious bias.
  • Courts and lawyers are increasingly asking about social media use, news habits, and online discussions during voir dire, because these can shape jurors’ views long before the trial starts.

Mini FAQ

Is voir dire only American?
No. It’s used in many common-law jurisdictions, though the details differ; in some places it focuses more on evidence admissibility than jury questioning.

Is voir dire the whole trial?
No. It is a preliminary step within the trial process, mainly about who can sit on the jury or whether certain evidence or witnesses are allowed.

TL;DR: Voir dire is the questioning process used to screen jurors (and sometimes witnesses) so the court can weed out bias and ensure a fair trial, literally “to speak the truth.”
