Cal. CCP § 1107

When an application is filed for the issuance of any prerogative writ, the application shall be accompanied by proof of service of a copy thereof upon the respondent and the real party in interest named in such application. The provisions of Chapter 5 (commencing with Section 1010) of Title 14 of Part 2 shall apply to the service of the application. However, when a writ of mandate is sought pursuant to the provisions of Section 1088.5, the action may be filed and served in the same manner as an ordinary action under Part 2 (commencing with Section 307). Where the real party in respondent’s interest is a board or commission, the service shall be made upon the presiding officer, or upon the secretary, or upon a majority of the members, of the board or commission. Within five days after service and filing of the application, the real party in interest or the respondent or both may serve upon the applicant and file with the court points and authorities in opposition to the granting of the writ.

The court in which the application is filed, in its discretion and for good cause, may grant the application ex parte, without notice or service of the application as herein provided.

The provisions of this section shall not be applicable to applications for the writ of habeas corpus, or to applications for writs of review of the Industrial Accident or Public Utilities Commissions.
