Other forms: grand juries
When someone is charged with a crime, a grand jury is a group that decides whether there's enough evidence to hold a trial.
A trial jury hears testimony, considers evidence, and delivers a verdict, while a grand jury decides whether there should be a trial at all. The first grand juries convened in medieval England. They were once nearly universal, but only Liberia and the U.S. still use them. Preliminary hearings, when a judge decides if there’s enough evidence for a trial, are more common today. A grand jury is grand not because it is majestic but because it has more jurors than a trial jury.
