The primary function of the grand jury is to examine all aspects of local government, ensuring that the county is being governed honestly and efficiently and that county monies are being handled judiciously. 

A grand jury is a body of the required number of persons (19 in San Luis Obispo County) returned from the citizens of the county before a court of competent jurisdiction and sworn to inquire of public offenses committed or triable within the county.

Each grand jury is charged and sworn to investigate or inquire into county matters of civil concern. [Penal Code Section (PC) § 888]
