The grand jury is an investigative body created for the protection of society and the enforcement of the law. Although the responsibilities of a juror are many and diverse, the four predominant functions include:

1. Civil Government Oversight. This is a major function of present day grand jurors, and considerable effort is devoted to these responsibilities. The grand jury may examine all aspects of county and city government and special districts to ensure that the best interests of Ventura County citizens are being served. Its activities do not involved Federal or State groups operating within the county. The grand jury reviews and evaluates procedures, methods and systems utilized by government to determine whether more efficient and economical programs may be employed. The grand jury is authorized to:
   
   
   1. Inspect and audit books, records and financial expenditures to ensure that public funds are properly accounted and legally spent.
      
      
   2. Required to inquire into the conditions of jails and detention centers.
      
      
   3. Inquire into any charges of willful misconduct in office by public officials or employees.
      
      
2. Citizen Complaints. As part of the civil function, the grand jury receives letters from citizens alleging mistreatment by officials, suspicions of misconduct or governmental inefficiencies. Complaints received from citizens are acknowledged and investigated for their validity. All complaints are kept confidential. If the situation warrants, and corrective action is under the jurisdiction of the grand jury, appropriate action is taken.
   
   
3. Accusations. In addition to its oversight function, the Grand Jury can consider allegations of misconduct by public officials. The results of this accusation can lead to the trial and removal of the public official from office.
   
   
4. Reporting. California Penal Code 933 directs the Grand Jury to prepare and issue a final report. California Penal Code Section 916 requires that all problems identified in the final report be accompanied by suggested means for resolution, including financial, where applicable. There may be interim reports that are released upon completion. The investigation findings are contained in reports published at the end of the Grand Jury's term of service. Elected officials are required to respond in writing to the Grand Jury's recommendations in the final report within 60 days, all others within 90 days.
