what type of jury is subjected to voir dire
Jury selection 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.
Jury trial Jury trials are used in a significant share of serious criminal cases in almost all common law lawful systems (Singapore, for example, is an exception), and juries or lay judges have been incorporated into the legal systems of many civil law countries for criminal cases. Only the United States makes routine use of jury trials in a wide variety of non-criminal cases. Other common law legal jurisdictions use jury trials only in a very select class of cases that make up a tiny share of the overall civil docket (like defamation suits in England and Wales), but true civil jury trials are almost entirely absent elsewhere in the world. Some civil law jurisdictions, however, have arbitration panels where non-legally trained members decide cases in select subject-matter areas relevant to the arbitration panel members' areas of expertise.
