California Code, Government Code - GOV § 56853

(a) If a majority of the members of each of the legislative bodies of two or more local agencies adopt substantially similar resolutions of application making proposals either for the consolidation of districts or for the reorganization of all or any part of the districts into a single local agency, the commission shall approve, or conditionally approve, the proposal.

(b) Except as provided in subdivision (c), a commission may order any material change in the provisions or the terms and conditions of the consolidation or reorganization, as set forth in the proposals of the local agencies. The commission shall direct the executive officer to give each subject agency mailed notice of any change prior to ordering a change. The commission shall not, without the written consent of all subject agencies, take any further action on the consolidation or reorganization for 30 days following that mailing. Upon written demand by any subject agency, filed with the executive officer during that 30-day period, the commission shall make determinations upon the proposals only after notice and hearing on the proposals. If no written demand is filed, the commission may make those determinations without notice and hearing. The application of any provision of this subdivision may be waived by consent of all of the subject agencies.

(c) The commission shall not order a material change in the provisions of a consolidation or reorganization, as set forth in the proposals of the local agencies pursuant to subdivision (a), that would add or delete districts without the written consent of the applicant local agencies.
