California Code, Government Code - GOV § 3524.78

(b) Except in cases of emergency as provided in subdivision (d), no meeting and conferring shall take place on any proposal subject to subdivision (a) until not less than seven consecutive days have elapsed to enable the public to become informed, and to publicly express itself regarding the proposals, as well as regarding other possible subjects of meeting and conferring, and thereafter, the employer shall, in an open meeting, hear public comment on all matters related to the meet and confer proposals.

(c) Forty-eight hours after any proposal that includes any substantive subject that has not first been presented as proposals for public reaction pursuant to this section is offered during any meeting and conferring session, those proposals and the position, if any, taken by the representatives of the employer, shall be a public record.

(d) Subdivision (b) shall not apply when the employer determines that, due to an act of God, natural disaster, or other emergency or calamity affecting the state, and that is beyond the control of the employer or recognized employee organization, it must meet and confer and take action upon a proposal immediately and without sufficient time for the public to become informed and to publicly express itself. In those cases, the results of the meeting and conferring shall be made public as soon as reasonably possible.
