Cal. Elec. Code § 9092
Not less than 20 days before he or she submits the copy for the state voter information guide to the State Printer, the Secretary of State shall make the copy available for public examination. Any elector may seek a writ of mandate requiring a copy to be amended or deleted from the state voter information guide. A peremptory writ of mandate shall issue only upon clear and convincing proof that the copy in question is false, misleading, or inconsistent with the requirements of this code or Chapter 8 (commencing with Section 88000) of Title 9 of the Government Code, and that issuance of the writ will not substantially interfere with the printing and distribution of the state voter information guide as required by law. Venue for a proceeding under this section shall be exclusively in Sacramento County. The Secretary of State shall be named as the respondent and the State Printer and the person or official who authored the copy in question shall be named as real parties in interest. If the proceeding is initiated by the Secretary of State, the State Printer shall be named as the respondent.
