JuryA jury is a sworn body of people (jurors) convened to hear evidence and render an impartial verdict (a finding of fact on a question) officially submitted to them by a court, or to set a penalty or judgment. Juries developed in England during the Middle Ages and are a hallmark of the English common law system. As such, they are used by the United Kingdom, the United States, Canada, Ireland, Australia, and other countries whose legal systems were derived from the British Empire.
Jury trialA jury trial, or trial by jury, is a legal proceeding in which a jury makes a decision or findings of fact. It is distinguished from a bench trial in which a judge or panel of judges makes all decisions. Jury trials are used in a significant share of serious criminal cases in many but not all common law judicial systems. The majority of common law jurisdictions in Asia (such as Singapore, India, Pakistan and Malaysia) have abolished jury trials on the grounds that juries are susceptible to bias.
Hung juryA hung jury, also called a deadlocked jury, is a judicial jury that cannot agree upon a verdict after extended deliberation and is unable to reach the required unanimity or supermajority. Hung juries usually result in the case being tried again. This situation can occur only in common law legal systems, because civil law systems either do not use juries at all or provide that the defendant is immediately acquitted if the majority or supermajority required for conviction is not reached during a single, solemn vote.
Grand juryA grand jury is a jury—a group of citizens—empowered by law to conduct legal proceedings, investigate potential criminal conduct, and determine whether criminal charges should be brought. A grand jury may subpoena physical evidence or a person to testify. A grand jury is separate from the courts, which do not preside over its functioning. Originating in England during the Middle Ages, grand juries are only retained in two countries, the United States and Liberia.
Jury selectionJury selection is the selection of the people who will serve on a jury during a jury trial. The group of potential jurors (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 or ID renewals. From those lists, summonses are mailed. A panel of jurors is then assigned to a courtroom. The prospective jurors are randomly selected to sit in the jury box.
