Venire

Jury selection are many methods used to choose the people who will serve on a jury. The jury pool, also known as the venire, is first selected from among the community using a reasonably random method. Jury lists are compiled from voter registrations and driver license/state ID renewals. From those lists, summons are mailed. A panel of jurors is then assigned to a courtroom. The prospective jurors are randomly selected to sit in the jury box. At this stage they will be questioned in court by the judge and/or attorneys in the United States. Depending on the jurisdiction, attorneys may have an opportunity to mount a challenge for cause argument or use one of a limited number of peremptory challenges. In some jurisdictions that have capital punishment, the jury must be death-qualified to remove those who are opposed to the death penalty. Jury selection and techniques for voir dire are taught to law students in trial advocacy courses. However, attorneys sometimes use expert assistance in systematically choosing the jury, although other uses of jury research are becoming more common. The jury selected is said to have been "empaneled."

Selected jurors are generally subjected to a system of examination whereby both the prosecution (or plaintiff, in a civil case) and defense can object to a juror. In common law countries, this is known as voir dire. Voir dire can include both general questions asked of an entire pool of prospective jurors, answered by means such as a show of hands, and questions asked of individual prospective jurors and calling for a verbal answer. In some jurisdictions, the attorneys for the parties may question the potential jurors; in other jurisdictions, the trial judge conducts the voir dire.

The method and scope of the possible rejections varies between countries:

In the United States the process of voir dire is often much more in depth than in other countries and its practical implementation is somewhat controversial because of this. The amount of privacy that the potential jurors are afforded when asked questions raises the issue of the definition of "impartial jury". Some people question if the intensive questioning of potential jurors looks not just for inherent bias but for a potential to be emotionally swayed. On the other hand, proponents argue that this method gives both sides more confidence in the verdict.
