A jury is the group of people who decide if a defendant is guilty or not guilty of a crime. A person who is arrested and goes before a judge is called a defendant. People on a jury are called jurors.
In the United States, every defendant has the right to have a trial by a jury of their peers. Peers are people who are like them.
A jury in a felony (FELL-o-nee) case has 12 people. A felony is a crime that is punishable by more than one year in jail or prison.
A jury in a misdemeanor (miss-de-MEEN-or) case has six people. A misdemeanor is a crime that is punishable by less than one year in jail.
