Gov. Code, § 11505

(a) Upon the filing of the accusation or District Statement of Reduction in Force the agency shall serve a copy thereof on the respondent as provided in subdivision (c). The agency may include with the accusation or District Statement of Reduction in Force any information that it deems appropriate, but it shall include a postcard or other form entitled Notice of Defense, or, as applicable, Notice of Participation, that, when signed by or on behalf of the respondent and returned to the agency, will acknowledge service of the accusation or District Statement of Reduction in Force and constitute a notice of defense, or, as applicable, notice of participation, under Section 11506. The copy of the accusation or District Statement of Reduction in Force shall include or be accompanied by (1) a statement that respondent may request a hearing by filing a notice of defense, or, as applicable, notice of participation, as provided in Section 11506 within 15 days after service upon the respondent of the accusation or District Statement of Reduction in Force, and that failure to do so will constitute a waiver of the respondent’s right to a hearing, and (2) copies of Sections 11507.5, 11507.6, and 11507.7.

(b) The statement to respondent shall be substantially in the following form:

Unless a written request for a hearing signed by or on behalf of the person named as respondent in the accompanying accusation or District Statement of Reduction in Force is delivered or mailed to the agency within 15 days after the accusation or District Statement of Reduction in Force was personally served on you or mailed to you, (here insert name of agency) may proceed upon the accusation or District Statement of Reduction in Force without a hearing. The request for a hearing may be made by delivering or mailing the enclosed form entitled Notice of Defense, or, as applicable, Notice of Participation, or by delivering or mailing a notice of defense, or, as applicable, notice of participation, as provided by Section 11506 of the Government Code to: (here insert name and address of agency). You may, but need not, be represented by counsel at any or all stages of these proceedings.

If you desire the names and addresses of witnesses or an opportunity to inspect and copy the items mentioned in Section 11507.6 of the Government Code in the possession, custody, or control of the agency, you may contact: (here insert name and address of appropriate person).

The hearing may be postponed for good cause. If you have good cause, you are obliged to notify the agency or, if an administrative law judge has been assigned to the hearing, the Office of Administrative Hearings, within 10 working days after you discover the good cause. Failure to give notice within 10 days will deprive you of a postponement.

(c) The accusation or District Statement of Reduction in Force and all accompanying information may be sent to the respondent by any means selected by the agency, but no order adversely affecting the rights of the respondent shall be made by the agency in any case unless the respondent has been served personally or by registered mail as provided herein, or has filed a notice of defense, or, as applicable, notice of participation, or otherwise appeared. Service may be proved in the manner authorized in civil actions. Service by registered mail shall be effective if a statute or agency rule requires the respondent to file the respondent’s address with the agency and to notify the agency of any change, and if a registered letter containing the accusation or District Statement of Reduction in Force and accompanying material is mailed, addressed to the respondent at the latest address on file with the agency.

(d) For purposes of this chapter, for hearings involving a reduction in force that are conducted pursuant to Section 44949, 45117, or 88017 of the Education Code, a “Notice of Participation” shall have the same meaning as a “Notice of Defense.”
