Cal. Gov. Code § 56843

If a reorganization committee does not complete and submit its report and recommendation before the date specified by the commission or, prior to that date, if members of the committee representing one-half or more of the subject districts report to the commission that the committee is unable to agree upon the report and recommendation, the commission may either order the discharge of the committee, or appoint additional members to the committee, not to exceed the maximum number authorized for a single subject district, to represent the public and order the committee, as so enlarged, to continue its study.
