Cal. Ed. Code § 23007
If any county superintendent, district superintendent, chancellor of a community college district, or other employing agency that reports directly to the system fails to make payment of any assessment by the board, the Controller shall, upon order of the board, withhold subsequent payments from the State School Fund to the county for deposit in the county school service fund or, upon the request of a county superintendent of schools to the county auditor, he or she shall withhold payments to a school district for deposit in the district general fund until the contributions and report are received in acceptable form in the office of the system and the board directs the Controller to make those payments, less the amount of the assessments to the county that would have been paid had no payments been withheld. The Controller shall then pay to the system the amount of the assessments withheld for deposit in the State Treasury to the Teachers' Retirement Fund.
