Grand jury

Grand jury, group of citizens who decide whether there is enough evidence to charge an individual with a crime. A grand jury never tries a case; its job is only to inquire and accuse. Originally, during the time of Henry III of England (1216–72), the grand jury not only inquired and accused, but also tried cases. In the United States the grand jury usually consists of 16 to 23 people, all legally adults and citizens.
