Nevada County Grand Juryhttp://nccourt.net/divisions/grand-jury.shtml
The major functions of a grand jury are divided into criminal indictments and civil investigations. There are three predominant functions:
1) “Watchdog” Responsibilities: The Grand Jury may examine all aspects of county and city government and special districts to ensure that the county is being governed honestly and efficiently and that county monies are being handled appropriately.
2) Citizen Complaints: The Grand Jury receives many letters from citizens alleging mistreatment by officials, suspicions of misconduct, or governmental inefficiencies.
3) Criminal Investigations: Under certain, extremely rare, circumstances the Grand Jury holds hearings to determine whether evidence presented by the district attorney is of sufficient nature to warrant persons having to stand trial in court.
