(a) In a county of the eighth class, as defined by Sections 28020 and 28029 of the Government Code, upon a request by the grand jury, the presiding judge of the superior court may retain, in the name of the county, a special counsel to the grand jury. The request shall be presented to the presiding judge in camera, by an affidavit, executed by the foreperson of the grand jury, which specifies the reason for the request and the nature of the services sought, and which certifies that the appointment of the special counsel is reasonably necessary to aid the work of the grand jury. The affidavit shall be confidential and its contents may not be made public except by order of the presiding judge upon a showing of good cause. The special counsel shall be selected by the presiding judge following submission of the name of the nominee to the board of supervisors for comment.

1. (1) The types of legal services to be rendered to the grand jury; provided, (i) that the special counsel’s duties shall not include any legal advisory, investigative, or prosecutorial service that by statute is vested within the powers of the district attorney, and (ii) that the special counsel may not perform any investigative or prosecutorial service whatsoever except upon advance written approval by the presiding judge, which specifies the number of hours of these services, the hourly rate therefor, and the subject matter of the inquiry.
2. (2) The hourly rate of compensation of the special counsel for legal advisory services delivered, together with a maximum contract amount payable for all services rendered under the contract during the term thereof, and all service authorizations issued pursuant thereto.
3. (3) That the contract may be canceled in advance of the expiration of its term by the presiding judge pursuant to service upon the special counsel of 10 days’ advance written notice.

The special counsel shall be retained under a contract executed by the presiding judge in the name of the county. The contract shall contain the following terms:

(c) The contract shall constitute a public record and shall be subject to public inspection and copying pursuant to the provisions of the California Public Records Act (Division 10 (commencing with Section 7920.000) of Title 1 of the Government Code). However, at the sole discretion of the board of supervisors, any or all of the following steps may be taken:

1. (1) The nomination by the presiding judge, and any or all actions by the board of supervisors in commenting upon the nominee and the comments, may be made confidential.
2. (2) The deliberations and actions may be undertaken in meetings from which the public is excluded, and the communication containing comments may constitute a confidential record that is not subject to public inspection or copying except at the sole discretion of the board of supervisors. Moreover, any written authorization by the presiding judge pursuant to paragraph (1) of subdivision (a) shall constitute a confidential record that is not subject to public inspection or copying except in connection with a dispute concerning compensation for services rendered.
