Cal. Code Regs. tit. 17 § 60055.19
Within ten days after issuance of the hearing officer determination that a hearing is required or ten days after a petition has been amended, the executive officer shall file with the hearing officer and serve upon the petitioner a response to the petition. The response shall contain the reasons for and the facts in support of the decision of the executive officer under review. If a petition for review raises claims or issues in a manner that is so vague or ambiguous that the executive officer cannot reasonably be expected to respond, the executive officer may, within the time allotted for responding, move that the hearing officer require a more definite statement of matters covered in the petition for review. If such motion is granted, the petitioner shall comply within ten days of issuance of the order of the hearing officer.
