Jury

Jury: A group of citizens sworn to decide questions of fact and return a verdict. A petit (trial) jury decides cases; a grand jury decides whether to bring criminal charges. In federal civil cases, a jury must begin with at least 6 and no more than 12 members (Fed. R. Civ. P. 48(a)), and federal juror qualifications are set by statute (28 U.S.C. § 1865).

How to research the term

To research jury, begin with the rule, statute or contract where the word is used. Each one can give it a slightly different meaning. Then compare that text with how courts in your area have applied it. Also check the local rules of your court, since they can add requirements. If your case is in state court, the state rules control. So start with our state procedures guide to find them. In the end, always confirm that the source you rely on is current.
