Grand Jury Duty

Find out what to expect if you've been summoned for grand jury service.

Like trial jurors, grand jurors are randomly selected to help ensure that the grand jury is an accurate representation of the population of the entire judicial district. Grand jurors don't serve on a trial like trial jurors, and the grand jury doesn't decide if someone is guilty or innocent. Grand jurors consider evidence presented by the prosecutor and decide if it's sufficient to bring a criminal charge.
