Cal. Ed. Code § 16101
Notwithstanding any provision of law to the contrary, if an apportionment is or has been made at any time after October 1, 1953, to meet a construction low bid and if the State Allocation Board after approving the apportionment revises the apportionment, and the apportionment finally approved reveals that an applicant school district receives excess construction area to what they are entitled to pursuant to Section 16044, and if a judgment for the collection of the excess apportionment has not been rendered by a court prior to September 11, 1957, the excess apportionment shall be computed by the Controller and shall be repaid pursuant to this section. The district shall repay the amount of excess apportionment, and the interest thereon, in equal annual installments within 20 years from the date it receives the excess apportionment. The rate of interest shall be the same rate as that fixed for the approved apportionment. The district may at any time before the end of the 20-year period for repayment elect to repay, and repay, the balance of the excess apportionment then unpaid, plus interest computed to the date of repayment of such balance.
