who can and is required by law to do jury service
Jury Serving on a jury is normally compulsory for individuals who are qualified for jury service. A jury is intended to be an impartial panel capable of reaching a verdict. Procedures and requirements may include a fluent understanding of the language and the opportunity to test jurors' neutrality or otherwise exclude jurors who are perceived as likely to be less than neutral or partial to one side. Juries are initially chosen randomly, usually from the eligible population of adult citizens residing in the court's jurisdictional area. Jury selection in the United States usually includes organized questioning of the prospective jurors (jury pool) by the lawyers for the plaintiff and the defendant and by the judge—voir dire—as well as rejecting some jurors because of bias or inability to properly serve ("challenge for cause"), and the discretionary right of each side to reject a specified number of jurors without having to prove a proper cause for the rejection ("peremptory challenge"), before the jury is impaneled.
