Contra Costa County’s Grand Jury consists of 19 citizens. A new Grand Jury is impaneled each year. Grand Jurors are officers of the court, and function as an independent body under the guidance of a Superior Court judge.
Apart from the investigations mandated by the California Penal Code, each county’s Grand Jury decides what it will investigate. Investigations may be initiated in response to letters from citizens, newspaper articles and personal knowledge.
