Grand Jury

A grand jury determines whether sufficient evidence exists to bring serious criminal charges.

Definition

A grand jury is a group of citizens that hears evidence presented by prosecutors and decides whether probable cause supports an indictment.

Why It Matters

It serves as a screening mechanism before certain criminal prosecutions.

How It Works

Proceedings are generally secret, and the prosecutor presents evidence without a trial judge deciding guilt.

History

Grand juries derive from English practice and are required by the Fifth Amendment for serious federal crimes.

Example

A federal grand jury may issue an indictment for fraud.

Common Misconceptions

  • A grand jury decides guilt.
  • Defendants always testify.
  • Every state must use grand juries in every felony case.
