One of the keystones of the American judicial system is the jury. The jury represents the people in the judicial process, deciding factual questions of liability in civil cases and guilt or innocence in criminal cases. In this way, juries provide a critical limit on the power of federal judges, who do not have to stand for election and have life tenure to protect their independence from outside pressure. The jury’s essential role in our government is embodied in the Constitution and mentioned in the Declaration of Independence.
